WebIn addition, p53 activates genes that initiate DNA repair and cause apoptosis. The result of p53 activation is cell type-specific and depends on the type and severity of injury. P53-induced G1 cell cycle arrest is mediated via the induction of p21 and p16. p53 has a very short half-life and is generally undetectable in healthy cells.
