You will be shown a claim related to the COVID-19 pandemic, and the abstract of a biomedical research paper. Each sentence from the abstract will be on a separate line. Your task is to return a JSON object with two fields:

- "verdict": The fact-checking verdict. If the information in the abstract supports the claim, write "SUPPORT". If the abstract contradicts the claim, write "CONTRADICT".
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract.

For instance, if the model were given the claim "the COVID vaccine is safe for healthy adults", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["Our findings indicate that the risks of severe COVID vaccine side effects are low for healthy adults."]
}

Claim: Bulk and single-cell transcriptomics identify tobacco-use disparity in lung gene expression of ace2, the receptor of hla-ncov

Abstract:
In current severe global emergency situation of 2019-nCov outbreak, it is imperative to identify vulnerable and susceptible groups for effective protection and care.
Recently, studies found that 2019-nCov and SARS-nCov share the same receptor, ACE2.
In this study, we analyzed five large-scale bulk transcriptomic datasets of normal lung tissue and two single-cell transcriptomic datasets to investigate the disparities related to race, age, gender and smoking status in ACE2 gene expression and its distribution among cell types.
We didn't find significant disparities in ACE2 gene expression between racial groups (Asian vs Caucasian), age groups (>60 vs <60) or gender groups (male vs female).
However, we observed significantly higher ACE2 gene expression in former smoker's lung compared to non-smoker's lung.
Also, we found higher ACE2 gene expression in Asian current smokers compared to non-smokers but not in Caucasian current smokers, which may indicate an existence of gene-smoking interaction.
In addition, we found that ACE2 gene is expressed in specific cell types related to smoking history and location.
In bronchial epithelium, ACE2 is actively expressed in goblet cells of current smokers and club cells of non-smokers.
In alveoli, ACE2 is actively expressed in remodelled AT2 cells of former smokers.
Together, this study indicates that smokers especially former smokers may be more susceptible to 2019-nCov and have infection paths different with non-smokers.
Thus, smoking history may provide valuable information in identifying susceptible population and standardizing treatment regimen.
