TP53 and cancer: Its activity against cancer appears to be closely associated with: mutational activation of Ras, deregulation of myc, overexpression of AP-1, amplification of cell cycle regulator cyclins D/E and Cdks 2/4, mutation of Fas and Bax, deletion of p53, disruption of DNA-damage response regulators Chk1/2 and ATM/ATR, overexpression of survival kinase AKT1, mutation of cell cycle inhibitors and translocation of anti-apoptotic Bcl-2 [106].
