As demonstrated in Figure 1A, KDM6B shared a lower expression level in the tumor tissues of BLCA (bladder urothelial carcinoma), BRCA (breast invasive carcinoma), COAD (colon adenocarcinoma), KICH (kidney chromophobe), LUAD (lung adenocarcinoma), LUSC (lung squamous cell carcinoma), THCA (thyroid carcinoma) (all p < 0.001), and LIHC (liver hepatocellular carcinoma) (p < 0.01). The gene discussed is KDM6B; the disease is lung adenocarcinoma.
