WebInactivation of RB1, and CDKN2A are very common, and p53 inactivation occurs in as many as 76% of MIBCs (Cancer Genome Atlas Research Network, 2014). Similarly loss of the tumor suppressor gene RB1 is common in MIBC and leads to amplification and overexpression of the oncogene E2F3 (Knowles and Hurst, 2015). WebAug 16, 2024 · The cellular consequences of RB1 inactivation have been associated with multiple forms of genomic instability, which fuels tumorigenesis by eliminating safeguards that limit oncogenic transformation [19,20,21,22]. Such genomic instability is a hallmark of almost all types of cancers.
