Since pRb’s first description as a transcriptional repressor of genes important for cell cycle progression, many more functions have been elucidated, e.g. in developmental decisions …
WebIn addition, cells lacking pRB are largely insensitive to p16 INK4-induced cell cycle arrest. The p16 INK4 /cyclin D/cdk4/pRB pathway is disrupted in a variety of ways in tumor cells. Retinoblastoma cells, for example, contain mutations in RB1. Many cervical cancers, on the other hand, express HPV E7 proteins that bind and inactivate all three ...
