TP53 and cancer: Current strategies targeting p53 in cancer include two types: one targets wtp53 by blocking the degeneration of wtp53 or prolonging its cellular life and disrupting the interaction between wtp53 and its negative regulators MDM2/MDM4; the other targets mtp53 by destabilization of highly accumulated GOF p53 mutants and reactivation of mtp53 via recovery of the wild-type conformation and activity [31,92,93].
