Multinucleated masses produced by the fusion of many cells; often associated with viral infections. In AIDS, they are induced when the envelope glycoprotein of the HIV virus binds to the CD4 antigen of uninfected neighboring T4 cells. The resulting syncytium leads to cell death and thus may account for the cytopathic effect of the virus.
Giant Cell Tumor of Bone
A bone tumor composed of cellular spindle-cell stroma containing scattered multinucleated giant cells resembling osteoclasts. The tumors range from benign to frankly malignant lesions. The tumor occurs most frequently in an end of a long tubular bone in young adults. (From Dorland, 27th ed; Stedman, 25th ed)
Giant Cell Arteritis
A systemic autoimmune disorder that typically affects medium and large ARTERIES, usually leading to occlusive granulomatous vasculitis with transmural infiltrate containing multinucleated GIANT CELLS. The TEMPORAL ARTERY is commonly involved. This disorder appears primarily in people over the age of 50. Symptoms include FEVER; FATIGUE; HEADACHE; visual impairment; pain in the jaw and tongue; and aggravation of pain by cold temperatures. (From Adams et al., Principles of Neurology, 6th ed)
Giant Cell Tumors
Granuloma, Giant Cell
Carcinoma, Squamous Cell
Carcinoma, Giant Cell
A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.
Carcinoma in Situ
A syndrome in the elderly characterized by proximal joint and muscle pain, high erythrocyte sedimentation rate, and a self-limiting course. Pain is usually accompanied by evidence of an inflammatory reaction. Women are affected twice as commonly as men and Caucasians more frequently than other groups. The condition is frequently associated with GIANT CELL ARTERITIS and some theories pose the possibility that the two diseases arise from a single etiology or even that they are the same entity.
Giant Cells, Langhans
Multinucleated cells (fused macrophages) seen in granulomatous inflammations such as tuberculosis, syphilis, sarcoidosis, and deep fungal infections. They resemble foreign-body giant cells (GIANT CELLS, FOREIGN BODY) but Langhans giant cells contain less chromatin and their nuclei are arranged peripherally in a horseshoe-shaped pattern. Langhans giant cells occur frequently in delayed hypersensitivity.
Carcinoma, Ductal, Breast
Carcinoma, Basal Cell
A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1471)
Carcinoma, Transitional Cell
Tumor Markers, Biological
Molecular products metabolized and secreted by neoplastic tissue and characterized biochemically in cells or body fluids. They are indicators of tumor stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including hormones, antigens, amino and nucleic acids, enzymes, polyamines, and specific cell membrane proteins and lipids.
Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
Carcinoma, Intraductal, Noninfiltrating
Carcinoma, Adenoid Cystic
Carcinoma characterized by bands or cylinders of hyalinized or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumors occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (Dorland, 27th ed)
Carcinoma, Small Cell
A carcinoma composed mainly of epithelial elements with little or no stroma. Medullary carcinomas of the breast constitute 5%-7% of all mammary carcinomas; medullary carcinomas of the thyroid comprise 3%-10% of all thyroid malignancies. (From Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1141; Segen, Dictionary of Modern Medicine, 1992)
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992)
Tumor Cells, Cultured
Gene Expression Regulation, Neoplastic
Neoplasm Recurrence, Local
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
A usually benign tumor composed of cells which arise from chondroblasts or their precursors and which tend to differentiate into cartilage cells. It occurs primarily in the epiphyses of adolescents. It is relatively rare and represents less than 2% of all primary bone tumors. The peak incidence is in the second decade of life; it is about twice as common in males as in females. (From Dorland, 27th ed; Holland et al., Cancer Medicine, 3d ed, p1846)
A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575; Holland et al., Cancer Medicine, 3d ed, p1240)
Head and Neck Neoplasms
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)
A highly malignant, primitive form of carcinoma, probably of germinal cell or teratomatous derivation, usually arising in a gonad and rarely in other sites. It is rare in the female ovary, but in the male it accounts for 20% of all testicular tumors. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, p1595)
Tomography, X-Ray Computed
Carcinoma, Merkel Cell
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Giant Cells, Foreign-Body
Multinucleated cells (fused macrophages), characteristic of granulomatous inflammation, which form around exogenous material in the skin. They are similar in appearance to Langhans giant cells (GIANT CELLS, LANGHANS), but foreign-body giant cells have more abundant chromatin and their nuclei are scattered in an irregular pattern in the cytoplasm.
A malignant neoplasm of the ADRENAL CORTEX. Adrenocortical carcinomas are unencapsulated anaplastic (ANAPLASIA) masses sometimes exceeding 20 cm or 200 g. They are more likely to be functional than nonfunctional, and produce ADRENAL CORTEX HORMONES that may result in hypercortisolism (CUSHING SYNDROME); HYPERALDOSTERONISM; and/or VIRILISM.
Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, esophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (Segen, Dictionary of Modern Medicine, 1992)
Carcinoma, Signet Ring Cell
Reverse Transcriptase Polymerase Chain Reaction
Neoplasms, Multiple Primary
Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies.
Carcinoma, Large Cell
Autosomal dominant neurocutaneous syndrome classically characterized by MENTAL RETARDATION; EPILEPSY; and skin lesions (e.g., adenoma sebaceum and hypomelanotic macules). There is, however, considerable heterogeneity in the neurologic manifestations. It is also associated with cortical tuber and HAMARTOMAS formation throughout the body, especially the heart, kidneys, and eyes. Mutations in two loci TSC1 and TSC2 that encode hamartin and tuberin, respectively, are associated with the disease.
A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Bone Cysts, Aneurysmal
A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
Characteristic cells of granulomatous hypersensitivity. They appear as large, flattened cells with increased endoplasmic reticulum. They are believed to be activated macrophages that have differentiated as a result of prolonged antigenic stimulation. Further differentiation or fusion of epithelioid cells is thought to produce multinucleated giant cells (GIANT CELLS).
Combined Modality Therapy
Tumor Suppressor Protein p53
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

Carcinoma, Non-Small-Cell Lung
In Situ Hybridization
Adenocarcinoma, Clear Cell
An adenocarcinoma characterized by the presence of varying combinations of clear and hobnail-shaped tumor cells. There are three predominant patterns described as tubulocystic, solid, and papillary. These tumors, usually located in the female reproductive organs, have been seen more frequently in young women since 1970 as a result of the association with intrauterine exposure to diethylstilbestrol. (From Holland et al., Cancer Medicine, 3d ed)
Cell Transformation, Neoplastic
Histiocytoma, Benign Fibrous
A benign tumor composed, wholly or in part, of cells with the morphologic characteristics of HISTIOCYTES and with various fibroblastic components. Fibrous histiocytomas can occur anywhere in the body. When they occur in the skin, they are called dermatofibromas or sclerosing hemangiomas. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 5th ed, p1747)
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS. (from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
A malignant cystic or semicystic neoplasm. It often occurs in the ovary and usually bilaterally. The external surface is usually covered with papillary excrescences. Microscopically, the papillary patterns are predominantly epithelial overgrowths with differentiated and undifferentiated papillary serous cystadenocarcinoma cells. Psammoma bodies may be present. The tumor generally adheres to surrounding structures and produces ascites. (From Hughes, Obstetric-Gynecologic Terminology, 1972, p185)
Synovitis, Pigmented Villonodular
Carcinoma, Lewis Lung
A carcinoma discovered by Dr. Margaret R. Lewis of the Wistar Institute in 1951. This tumor originated spontaneously as a carcinoma of the lung of a C57BL mouse. The tumor does not appear to be grossly hemorrhagic and the majority of the tumor tissue is a semifirm homogeneous mass. (From Cancer Chemother Rep 2 1972 Nov;(3)1:325) It is also called 3LL and LLC and is used as a transplantable malignancy.
A polypeptide hormone of approximately 25 kDa that is produced by the SYNCYTIOTROPHOBLASTS of the PLACENTA, also known as chorionic somatomammotropin. It has both GROWTH HORMONE and PROLACTIN activities on growth, lactation, and luteal steroid production. In women, placental lactogen secretion begins soon after implantation and increases to 1 g or more a day in late pregnancy. Placental lactogen is also an insulin antagonist.
Magnetic Resonance Imaging
Tissue Array Analysis
A nonparametric method of compiling LIFE TABLES or survival tables. It combines calculated probabilities of survival and estimates to allow for observations occurring beyond a measurement threshold, which are assumed to occur randomly. Time intervals are defined as ending each time an event occurs and are therefore unequal. (From Last, A Dictionary of Epidemiology, 1995)
Sensitivity and Specificity
Carcinoma, Pancreatic Ductal
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
Tumor Suppressor Proteins
Gene Expression Profiling
Histiocytoma, Malignant Fibrous
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
The pathological process occurring in cells that are dying from irreparable injuries. It is caused by the progressive, uncontrolled action of degradative ENZYMES, leading to MITOCHONDRIAL SWELLING, nuclear flocculation, and cell lysis. It is distinct it from APOPTOSIS, which is a normal, regulated cellular process.
Loss of Heterozygosity
Mammary Neoplasms, Experimental
Inflammation of the synovial lining of a tendon sheath. Causes include trauma, tendon stress, bacterial disease (gonorrhea, tuberculosis), rheumatic disease, and gout. Common sites are the hand, wrist, shoulder capsule, hip capsule, hamstring muscles, and Achilles tendon. The tendon sheaths become inflamed and painful, and accumulate fluid. Joint mobility is usually reduced.
In Situ Hybridization, Fluorescence
The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.
Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
A phylum of the kingdom Metazoa. Mollusca have soft, unsegmented bodies with an anterior head, a dorsal visceral mass, and a ventral foot. Most are encased in a protective calcareous shell. It includes the classes GASTROPODA; BIVALVIA; CEPHALOPODA; Aplacophora; Scaphopoda; Polyplacophora; and Monoplacophora.
A cell surface protein-tyrosine kinase receptor that is overexpressed in a variety of ADENOCARCINOMAS. It has extensive homology to and heterodimerizes with the EGF RECEPTOR, the ERBB-3 RECEPTOR, and the ERBB-4 RECEPTOR. Activation of the erbB-2 receptor occurs through heterodimer formation with a ligand-bound erbB receptor family member.
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
Optic Neuropathy, Ischemic
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy.

Study on the metastatic mechanisms of human giant-cell lung carcinoma comparison between the strains C and D. (1/25)The biologic characteristics of the two human giant-cell lung carcinoma strains with high (strain D) and low metastatic potential (strain C) were studied, including karyotype of chromosome, intracellular free calcium ([Ca2+]i), morphologic changes of cell surface and the expression of nm23-H1, p53, ras, c-myc, c-erbB2, bcl-2 genes and PCNA. The correlation between different biologic features and the metastatic potential of the two strains was analyzed. We found: 1) Both strains had the karyotypic abnormality of -13, -14, -15, +20, +21 with seven same marker chromosomes. Only strain D had the karyotypic abnormality of +7, -17, -18, +X, 7p+; 2) [Ca2+]i of the strain C (984.7 +/- 573.8) and D (517.6 +/- 216.6) was significantly different (p < 0.05). The amplitude of intracellular calcium oscillations of strain C was lower than the one of strain D; 3) strain C had more villous-like protrusions on the cell surface, whereas strain D had more bubble-like protrusions; 4) The expression of nm23-H1 and p53 protein of strain C was all higher than that of strain D. The expression of PCNA of strain C was lower than strain D; 5) nm23-H1 mRNA levels of strain C was lower than that of strain D. We consider that the karyotype of chromosomes, intracellular free calcium, the structure of cell membrane and the expression of nm23-H1 gene, p53 gene, PCNA could be closely related to the metastatic potential of human giant-cell lung carcinoma. They could be used as the sign for judging whether the tumor will metastasize in clinical practice as well as in judging the prognoses of patients. (+info)
Effect of interleukin-6 on the growth of human lung cancer cell line. (2/25)OBJECTIVE: To investigate the effect of interleukin-6 (IL-6) on the growth of human lung cancer in vivo as well as in vitro. METHODS: To examine the mRNA level of IL-6 receptor (IL-6R) in high-metastatic human lung giant cell carcinoma cell line PG by means of reverse transcription polymerase chain reaction (RT-PCR). To assess the existence of IL-6 receptor complex (including IL-6R and gp130) with the treatment of PG cells by use of recombinant human IL-6 (rhIL-6), recombinant human oncostatin M (rhOSM), and recombinant human leukemia inhibitory factor (rhLIF), respectively. To detect the expression of IL-6 by Northern blotting hybridization and bioactive assay. To identify the effect of IL-6 secreted by PG cells by use of IL-6 and IL-6R antisense oligodeoxynucleotides (ODNs), and specific neutralizing antibody to IL-6. To document the influence of IL-6 on PG cells growth in vivo through the strategy of the transfection of expression vector inserted antisense IL-6 cDNA. RESULTS: RT-PCR analysis revealed that PG cells expressed IL-6R mRNA. Any one of the recombinant cytokine IL-6, OSM and LIF stimulated the growth of PG cells in vitro in a concentration-dependent manner. These results demonstrated IL-6 receptor complex exist in PG cells. At the same time, PG cells expressed IL-6 mRNA and secreted bioactive IL-6. Both IL-6 antisense ODNs and IL-6R ODNs inhibited PG cells proliferation. Treatment of PG cells with IL-6 antibodies reduced the growth of PG cells in vitro. PG cells transfected with IL-6 antisense expression vector showed a decreased growth in nude mice. CONCLUSION: IL-6 functions as an autocrine growth stimulator for PG cells in vivo as well as in vitro. (+info)
Pleomorphic carcinoma: report of a case with massive pleural effusion and asbestos particles. (3/25)Pleomorphic (spindle/giant cell) carcinoma (PC) is one subset of large cell carcinoma. It is well known that PC patients have a poor survival rate. This report describes a 68-year-old man with PC. The patient's tumor had a massive pleural effusion. A left lower lobectomy and partial resection of the left diaphragm, peritoneum, and parietal pleura were performed to remove the tumor. Numerous asbestos particles were found in the left lower lobe. This is the first reported case of PC which may have been caused by asbestos particles. Further investigation is needed into whether asbestos exposure causes PC. (+info)
Effective asymmetry in gap junctional intercellular communication between populations of human normal lung fibroblasts and lung carcinoma cells. (4/25)The dysfunction of homologous and/or heterologous gap junctional intercellular communication (GJIC) has been implicated in tumorigenesis of many kinds of cells. Here we have characterized GJIC and the expression of connexins in six human lung carcinoma cell lines and normal lung fibroblasts (HLF). Compared with HLF, all the carcinoma cells showed reduced or little homologous GJIC. They expressed remarkably reduced connexin(Cx)43 mRNA and variable levels of Cx45 mRNA, but neither Cx43 nor Cx45 protein could be detected. However, using a preloading assay, transfer of calcein was observed between donor HLF cells and first order neighboring recipient tumor cells (recipient cells in 1000-fold excess). Transfer from tumor to HLF cells under the same conditions was not seen, although increasing the ratio of donor tumor cells to recipient HLF cells and plating the cells at low density did reveal weak transfer from tumor cells to HLF. Transfection of Cx43 into giant cell carcinoma PG cells increased homologous communication and eliminated the rectifying behavior of heterologous communication. This indicates that the apparent rectification of dye transfer between normal and tumor cells was a product of low rates of heterologous transfer linked to (i) rapid dilution of the dye to below detectable limits through a very well coupled cell population (tumor to HLF) and (ii) concentration of dye in immediate neighbors in a poorly coupled cell population (HLF to tumor cells). These results suggest that the coupling levels may need to exceed a certain threshold to allow propagation of signals over a sufficient distance to affect behavior of a cell population. We propose that the relative rates of heterologous and homologous coupling of cell populations and the 'pool size' of shared metabolites in tumor cells and the surrounding normal tissue are likely to be very important in the regulation of their growth.

Clinicopathological features of giant cell carcinoma of the pancreas. (5/25)BACKGROUND: Giant cell carcinoma of the pancreas (GCCP) as a tumor of high malignancy, large size, and inflammatory reaction occupies 2.1%-12.8% of all cases of pancreatic malignancies. This study was to analyze cases of GCCP collected in 8 years at our hospital in an attempt to describe some features of GCCP in Chinese people. METHODS: The clinicopathological features of 19 patients who had been pathologically diagnosed as having GCCP from 1021 patients with pancreatic malignancies collected by Pancreatic Disease Research Group (PDRG) of Changhai Hospital were retrospectively analyzed compared with those of 96 patients with common pancreatic carcinoma (PC) who were randomly selected from 1002 patients with pancreatic carcinoma. The differences of location, clinical symptoms, imagings, laboratory test, operation and the prognosis of these two groups were defined. RESULTS: Tumors in the head of the pancreas were found in 8 patients (42.1%), and those in the body or tail of the pancreas in 11 (57.9%). The initial symptom was abdominal pain in most patients (57.9%). Abdominal pain (73.7%), dyspepsia (63.2%), weight loss (36.8%) but jaundice were common at the time of diagnosis. The abnormal rates of routine laboratory tests in the GCCP group were lower than those in the common PC group. The assay of tumor markers between the groups of GCCP and common PC was approximately the same. The sensitivity and accuracy of ultrasonography, spiral computed tomography and magnetic resonance imaging were considerably high. Large carcinoma in stage IV was seen in 9 patients or 47.4% of the GCCP group, a rate higher than that in the common PC group. Osteoid formation was found microscopically in some patients, and poorly differentiated tumor cells were found in most patients. The 1-year survival rate was 17.6%, which was lower than that in the common PC group. CONCLUSION: The clinicopathological features of GCCP are different from those of common PC. Imaging tests can be used together with the assay of tumor markers to diagnose GCCP as early as possible and to improve the prognosis of GCCP patients. (+info)
Structure analysis and expressions of a novel tetratransmembrane protein, lysosoma-associated protein transmembrane 4 beta associated with hepatocellular carcinoma. (6/25)AIM: To analyze the structure and expressions of the protein encoded by an HCC-associated novel gene, lysosome-associated protein transmembrane 4 beta (LAPTM4B). METHODS: Primary structure and fundamental characteristics of LAPTM4B protein were analysed with bioinformatics. Expressions of LAPTM4B in HCC tissues and various cell lines were detected using polyclonal antibodies and Western blot. RESULTS: LAPTM4B encoded two isoforms of proteins with molecular masses 35-ku and 24-ku, respectively. The expression level of LAPTM4B-35 protein in HCC tissues was dramatically upregulated and related to the differentiation status of HCC tissues, and it was also high in some cancer cell lines. Computer analysis showed LAPTM4B was an integral membrane protein with four transmembrane domains. LAPTM4B showed relatively high homology to LAPTM4A and LAPTM5 in various species. CONCLUSION: LAPTM4B gene encoded two isoforms of tetratransmembrane proteins, LAPTM4B-35 and LAPTM4B-24. The expression of LAPTM4B-35 protein is upregulated and associated with poor differentiation in human HCC tissues, and also at high levels in some cancer cell lines. LAPTM4B is an original and conserved protein. (+info)
Combined osteoclastic giant cell and pleomorphic giant cell tumor of the pancreas: a rarity. An immunohistochemical analysis and review of the literature. (7/25)CONTEXT: The combination of an osteoclastic giant cell tumor and a pleomorphic giant cell carcinoma of the pancreas is distinctly unusual and is associated with an adverse outcome. The origin of these two components within a tumor has long been debated based on the immunohistochemical and ultra-structural analysis. CASE REPORT: Herein we describe a tumor with amalgamation of these two distinct histomorphologies along with a minute focus of well-differentiated ductal adenocarcinoma (on multiple sections) in a 50-year male. On immunohistochemical analysis, osteoclastic giant cells were reactive for CD68 and vimentin confirming histiocytic/mesenchymal derivation whereas pleomorphic giant cells and mononuclear cells were reactive for cytokeratin which proved their epithelial nature. CONCLUSIONS: Although the present case had an equal proportion of both components, it is very important to correctly assess the predominant histology since osteoclastic giant cell tumor has a better prognosis as compared to the more aggressive pleomorphic giant cell carcinoma component.

Aggressive giant cell tumour of bone. (8/25)INTRODUCTION: The surgical treatment of Stage III or aggressive giant cell tumour of the bone, whether to perform intralesional or en-bloc resection, remains controversial. The aim of this study is to identify the effectiveness of en-bloc resection for local control and final oncological outcome of the disease. METHODS: The data of 20 consecutive patients with Stage III giant cell tumour were retrospectively reviewed to determine the local control and oncological outcome after treatment with wide resection. RESULTS: The majority of the patients presented late with mean duration of symptoms of 24 months, and four patients presented with recurrences. All patients were treated with wide resection except for two patients who underwent ablative surgery due to major neurovascular involvement. Ten patients required free vascularised tissue transfer to cover massive soft tissue defect. Local recurrence occurred in one patient who was again treated with wide resection and vascularised flap. Six patients had pulmonary metastases. Two patients with resectable disease were treated with thoracoscopic surgery and they remained disease-free 36 months after surgery. Two patients with multiple lung metastases were treated with chemotherapy and the disease remained non-progressive. The remaining two patients who refused chemotherapy showed radiological progression, and one succumbed to the disease with massive haemoptysis. CONCLUSION: Aggressive giant cell tumour of bone should be treated with wide resection for better local control, and treatment of pulmonary metastases is mandatory for overall prognosis. (+info)

Osteoclastic giant cell rich undifferentiated pleomorphic sarcoma of the vulva- A rare case report | International Journal of...
Background: Undiffrentiated pleomorphic sarcoma of vulva with osteoclastic giant cells is a diagnosis of exclusion. It is an exceptionally uncommon diagnostic finding which was eventually diagnosed in our institute and this required a methodical clinical approach and extensive immunohistochemical markers to rule out other probable diagnostic possibilities at this site. The quick diagnostic approach at our institute was ensued by operation. Case Report: 53 years old female presented with vulval growth to our institute. Incision biopsy was performed as a routine procedure. Biopsy showed atypical spindle cells with few cells showing rhabdoid morphology and osteoclast like giant cells were also present. Histological findings with aid of immunohistochemistry led to the diagnosis of undifferentiated pleomorphic sarcoma with osteoclast like giant cells. The tumor cells stained intensely for vimentin (a mesenchymal marker), but no immunoreactivity for the Cytokeratin Pan (epithelial cells marker), ...

Pulmonary Sarcomatoid carcinoma: a surgical diagnosis and prognostic factors | Read by QxMD
INTRODUCTION: Pulmonary Sarcomatoid Carcinoma (PSC) is a rare group of tumors accounting for about 0.4% of non-small cell lung carcinoma (NSCLC). Five subtypes were described: pleomorphic carcinoma, spindle cell carcinoma, carcinosarcoma, giant cell carcinoma and pulmonary blastoma. The diagnosis is pathological but requires a good quality sampling of the tumor.. METHODS: On a series of 1582 patients operated on for lung cancer from 1992 to 2016, 43 patients were retrospectively identified as having been treated surgically for pulmonary sarcomatoid carcinoma.. RESULTS: The population consisted of 33 males and 10 females with mean age of 55 years. Imaging findings showed a peripheral mass in the majority of cases (n=29). Careful investigation failed to discover a primitive lesion elsewhere. Six patients received induction therapy for wall involvement. Lobectomy or bilobectomy was performed in 30 patients and pneumonectomy in 11 patients. A wedge resection was performed in one patient and an ...
Computed tomographic features of pulmonary sarcomatoid carcinoma | OncologyPRO
The mean age of patients was 56.8 years (range, 46-73 years). The CT appearance of the tumor was similar for all our patients: Large mass, peripheral, heterogeneous density, with massive necrotic tissue component that strongly heightened after contrast injection; tumor had a locoregional extension with parietal and bone invasion (n = 5) and a distance extension (n = 4) to the adrenal glands. Pathological examination found a pleomorphic carcinoma (n = 3), a giant cell carcinoma (n = 1) and a carcinosarcoma (n = 2). Sarcomatoid carcinoma diagnosis was increased for the remaining patients without precision of histological subtype. ...
The insulator protein CTCF regulates Drosophila steroidogenesis | Biology Open
It has been reported that at the onset of pupariation there is an increase of lipid droplets in PG cells that can be seen by Oil Red O staining of precisely staged 120 h AEL wandering larvae (Talamillo et al., 2013). At 120 h AEL, phm,CTCFRNAi PGs had a reduced content of lipid droplets in comparison to controls (Fig. 4B, compare middle and left panels), likely due to developmental delay. However, there is also an increase of lipid droplets at the end of larval development in phm,CTCFRNAi PG cells which tend to be slightly higher than in control animals (Fig. 4B, compare right and left panels and supplementary material Fig. S4). Since the subcellular lipid accumulation phenotype of phm,CTCFRNAi PG cells is similar to that of Niemann-Pick type C (npc) mutants (Huang et al., 2005), we analyzed dnpc1a transcriptional levels but we found no changes between control and phm,CTCFRNAi larvae (data not shown). Increased lipid accumulation in the fat body in EcR knockdown larvae has been reported ...
We also analyzed the latency and jitter (the SD of the latency) of responses to ON stimulation. Across the entire GAD65+ PG cell population latencies ranged from 1.8 to 8.2 ms (mean: 3.61 ± 0.22 ms; Fig. 3D) and jitter ranged from 30 to 2,616 μs (mean: 470 ± 70 μs; Fig. 3E). However, cells with spontaneous and ON-evoked single EPSCs had significantly lower latency (2.63 ± 0.06 ms, range: 1.79-4.08 ms) and jitter (173 ± 9 μs, range: 31-298 μs) than cells with spontaneous and ON-evoked EPSC bursts (latency: 4.62 ± 0.3 ms, P , 0.000001, range: 2.16-8.20 ms; jitter 774 ± 119 μs, P , 0.000001; range: 309-2,616 μs).. ET cells provide monosynaptic burst input to ∼70% of PG cells (Hayar et al. 2004b). Thus the burst-sEPSC PG cell responses to ON input may derive from the disynaptic, ON→ET→PG circuit. However, mitral/tufted (M/T) cells could also contribute to this burst response: Back propagation of action potentials initiated near the M/T cell soma into the apical dendrites might ...

Aneurysmal Bone Cyst located in the Mandibular Condyle | Head & Face Medicine | Open peer review
A rare case of aneurysmal bone cyst (ABC) located in the mandibular condyle in a 10-year-old boy is presented. The patient came to our attention for a sudden swelling in the right temporomandibular region, the mouth opening was not reduced. A rapid growing mass, depicting soft tissue invasion, in the right condyle of the mandible was found. Clinically and radiographically it resembled to a malignant lesion. The surgical excision of the mandibular condyle allowed a complete removal of the lesion. The histological examination revealed a pseudocystic expanding osteolytic lesion containing blood-filled space separated by connective tissue and many osteoclastic giant cells, which was a conventional vascular ABC. The ABC is an infrequent bone lesion which can only be found very rarely at the craniofacial skeleton. There have been described about 160 cases of ABC originated in the molar region or in upper maxilla and even more rare is the location of this cyst in the mandibular condyle. Only 6 cases were

NGC 6940 - Wikipedia
NGC 6940 is an open cluster in the constellation Vulpecula. It was discovered by William Herschel in 1784. The cluster is nearly a billion years old and it is located 2,500 light years away. It is considered the finest open cluster in the constellation. It is located a bit more than two degrees south-southeast of 41 Cygni and three and a half degrees southwest from 52 Cygni. The cluster is bright enough to be seen even with small binoculars, which can partially resolve it. NGC 6940 is included in the Herschel 400 Catalogue. NGC 6940 has hundreds of members. The cluster is quite scattered and in between its members are also visible field stars. For example, two bright stars, a 8.6 mag B8III giant star at the NE edge and a 9.1 mag A0III giant at the SW corner of the cluster are too young to be true members of NGC 6940 and are probably background stars. The brightest star (lucida) of NGC 6940 is the red giant VG Vulpeculae, a semiregular variable star whose magnitude ranges from 9.0 to 9.5 every 80 ...

Parent of origin imprints on the genome have been implicated in the regulation of neural cell type differentiation. The ability of human parthenogenetic (PG) embryonic stem cells (hpESCs) to undergo neural lineage and cell type-specific differentiation is undefined. We determined the potential of hpESCs to differentiate into various neural subtypes. Concurrently, we examined DNA methylation and expression status of imprinted genes. Under culture conditions promoting neural differentiation, hpESC-derived neural stem cells (hpNSCs) gave rise to glia and neuron-like cells that expressed subtype-specific markers and generated action potentials. Analysis of imprinting in hpESCs and in hpNSCs revealed that maternal-specific gene expression patterns and imprinting marks were generally maintained in PG cells upon differentiation. Our results demonstrate that despite the lack of a paternal genome, hpESCs generate proliferating NSCs that are capable of differentiation into physiologically functional ...

Factor VIII has a domain organization A1-A2-B-A3-C1-C2 and synthesized as single-chain polypeptide of 2351 amino acids, from which you cut the signal peptide of 19 amino acids during translocation into the lumen of the endoplasmic reticulum. Due to the fact that factor VIII is bad glycosylases, it was difficult to achieve a high expression level (,0.2 PG/cell/day) factor VIII (Lind et al., 1995, Eur J Biochem. 232: 19-27; Kaufman et al., 1989, Mol Cell Biol. 9: 1233-1242). Expression of factor VIII in mammalian cells usually 2-3 orders of magnitude lower than the expression of other genes using similar vectors and techniques. The productivity of cell lines to obtain factor VIII is in the range of 0.5-1 MCED/KL/d (0.1-0.2 PG/CL/d).. It was shown that the B-domain of factor VIII is irrelevant to protagonizada activity. Different groups reported improvement in the expression of factor VIII in mammalian cells using truncated variants of factor VIII (Lind et al., 1995, Eur J Biochem 232: 19-27; ...

Giant Cell Tumor of Bone - an Overview
Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal cells and the presence of many multi- nucleated giant cells with homogenous distribution. There is no widely held consensus regarding the ideal treatment method selection. There are advocates of varying surgical techniques ranging from intra-lesional curettage to wide resection. As most giant cell tumors are benign and are located near a joint in young adults, several authors favor an intralesional approach that preserves anatomy of bone in lieu of resection. Although GCT is classified as a benign lesion, few patients develop progressive lung metastases with poor outcomes. Treatment is mainly surgical. Options of

From UniProt:. Porokeratosis 8, disseminated superficial actinic type (POROK8): A form of porokeratosis, a disorder of faulty keratinization characterized by one or more atrophic patches surrounded by a distinctive hyperkeratotic ridgelike border called the cornoid lamella. The keratotic lesions can progress to overt cutaneous neoplasms, typically squamous cell carcinomas. Multiple clinical variants of porokeratosis are recognized, including porokeratosis of Mibelli, linear porokeratosis, disseminated superficial actinic porokeratosis, palmoplantar porokeratosis, and punctate porokeratosis. Disseminated superficial actinic porokeratosis (DSAP) is the most common subtype. It is characterized by multiple small, annular, anhidrotic, keratotic lesions that are located predominantly on sun-exposed areas of the skin, such as the face, neck, and distal limbs. The lesions typically begin to develop in adolescence and reach near-complete penetrance by the third or fourth decade of life. ...

Diagnostic Radiology/Musculoskeletal Imaging/Tumors Basic/Giant cell tumor - Wikibooks, open books for an open world
Giant cell tumors of the bone are uncommon bone tumors which represent around 4-5% of primary bone tumors and 18% of all benign bone lesions. They are interesting in the fact that their classic radiographic appearance is easily identifiable. Giant cell tumors can either be benign or malignant, although the majority of them are benign. Radiographically, benign versus malignant tumors are difficult to distinguish. In most patients, the tumor has an indolent course, but repeated local recurrence of the tumor does happen. Approximately 5% of giant cell tumors are defined as malignant. Malignancy usually occurs as the result of malignant transformation after radiation therapy. These tumors are slightly more common in females, with 50-57% of cases occurring in females. The general age range for giant cell tumors is 20-40 years old. Approximately 85% of tumors occur in the long bones, namely the distal femur, proximal tibia, proximal humerus, and distal radius. Another location typical of giant cell ...
