p53 and Fas Are Sequential Mechanisms of Testicular Germ Cell Apoptosis

Abstract excerpt

Testicular germ cell apoptosis in the cryptorchid testis is induced by abdominal heat stress. p53-dependent apoptosis appears responsible for the initial phase of germ cell loss in experimental cryptorchidism based on a 3-day delay of apoptosis in p53-/- mice. However, the mechanisms underlying the subsequent p53-independent apoptosis have not been identified. Although studies have suggested that Fas plays a role...
