Question: Is lactotransferrin a tumour suppressor?

Context: LTF (lactotransferrin, or lactoferrin) plays important role in innate immunity, and its anti-tumor function has also been reported in multiple cancers.
We previously reported that LTF is significantly down-regulated in nasopharyngeal carcinoma (NPC) and acts as a tumor suppressor by suppressing AKT signaling.
The tumor suppressor function of lactotransferrin (LTF) has been reported in a variety of tumors, including GC, nasopharyngeal carcinoma (NPC) and prostate cancer.
Lactotransferrin (LTF) has been confirmed to act as a tumor suppressor in multiple cancers
Lactotransferrin acts as a tumor suppressor in nasopharyngeal carcinoma by repressing AKT through multiple mechanisms.
LTF is likely to be a candidate tumor suppressor and downregulates the development of NPC by inhibiting NPC proliferation through induction of cell cycle arrest and modulation of the MAPK signaling pathway.
