RNA expression aberration of ACE2 in tumors. a RNA expression aberration of ACE2 in tumors using GEPIA2 (upper panel) and Ualcan (lower panel) database. Red, tumor samples; grey, normal control samples. b Colon adenocarcinoma (COAD), kidney renal papillary cell carcinoma (KIRP), pancreatic adenocarcinoma (PAAD), rectum adenocarcinoma (READ), lung adenocarcinoma (LUAD), and stomach adenocarcinoma (STAD) presented increased ACE2 expression. *p < 0.05. This data was obtained using GEPIA2. Red, tumor samples; grey, normal control samples. c Testicular germ cell tumors (TGCT), thyroid carcinoma (THCA), and kidney chromophobe (KICH) presented decreased ACE2 expression. *p < 0.05. This data was obtained using GEPIA2. Red, tumor samples; grey, normal control samples.
