Figure 4A shows that RCAN1 expression is considerably decreased in various cancers, including bladder urothelial carcinoma (BLCA), breast invasive carcinoma (BRCA), kidney chromophobe (KICH), kidney renal papillary cell carcinoma (KIRP), liver hepatocellular carcinoma (LIHC), and lung adenocarcinoma (LUAD). Here, RCAN1 is linked to lung adenocarcinoma.
