Interestingly, a second bioinformatics study on Oncomine and TCGA databases gave slightly different results in terms of tumor-associated ACE2 expression changes, but confirmed the role of promoter hypomethylation in KIRP and uterine corpus endometrial carcinoma (UCEC) where ACE2 transcription was significantly upregulated (Yang et al., 2020a). The gene discussed is ACE2; the disease is neoplasm.
