Fas is involved in the p53-dependent apoptotic response to ionizing radiation in mouse testis.

Abstract excerpt

Apoptosis induced in male germ cells following ionizing radiation is dependent on functional p53 (Trp53) being present. We sought to determine whether Fas (Tnfrsf6/CD95/APO-1), an apoptotic factor, is involved in this p53-dependent germ cell death. In p53 knock-out mice exposed to 5 Gy of x-radiation, germ cells were protected from cell death, as assessed by counting apoptotic seminiferous tubules 12 h following...
