In addition, evidence suggests that CDKN2B-AS1 acts as competing endogenous RNA (ceRNA) and as a molecular sponge for microRNA let-7a27,28, miR-125a29, miR-99a/miR-449a30, and miR-122-5p31, which are involved in the progression of prostate cancer, nasopharyngeal cancer, oral carcinoma, gastric cancer, and hepatocellular carcinoma, respectively. The gene discussed is CDKN2B; the disease is Familial prostate cancer.
