Figure 1A shows that YTHDF2 expression was substantially higher in BLCA (bladder urothelial carcinoma), breast invasive carcinoma, colon adenocarcinoma, esophageal carcinoma, LUAD (lung adenocarcinoma), stomach adenocarcinoma, prostate adenocarcinoma, and UCEC (uterine corpus endometrial carcinoma) tissues than in adjacent normal tissues. The gene discussed is YTHDF2; the disease is gastric adenocarcinoma.
