claim: no ace2 expression found in fat and cancer cells
evidence_1: ace2 expression correlated with increased macrophage abundance in some tumors, while tmprss2 was strongly associated with epithelial cells.", "results matched normal tissues generally display higher ace2 and tmprss2 expression compared with cancer, with normal and tumor from digestive organs expressing the highest levels.", "the expression of ace2 and tmprss2 was significantly higher in normal tissues relative to tumors (figure 1c).", "by the search for network database and re-analysis of pubic data, we found the level of ace2 expression in adipose tissue was higher than that in lung tissue, which indicated the adipose tissue might be vulnerable to sars-cov-2 as well; the levels of ace2 expressed by adipocytes and adipose progenitor cells were similar between non-obese individuals and obese individuals, but obese individuals have more adiposes so as to increase the number of ace2-expressing cells; the expression of ace2 in tumor tissues posed by five different types of cancers increased significantly compared with that in adjacent tissues."
