CCNB1 and cancer: Oncogenes such as MYC, AKT1, AKT2, cyclins CCNA2, CCNB1, CCNB2, CCNE1, CCNE2 and cyclin-dependent kinases CDK1 and CDK4, which were upregulated under androgen treatment, exhibited a significantly reduced expression following PVT1 knockdown, thereby modulating cancer-associated oncogenic pathways.
