Apoptosis regulator Bcl-w is essential for spermatogenesis but appears otherwise redundant

Abstract excerpt

Proteins of the Bcl-2 family are important regulators of apoptosis in many tissues of the embryo and adult. The recently isolated bcl-w gene encodes a pro-survival member of the Bcl-2 family, which is widely expressed. To explore its physiological role, we have inactivated the bcl-w gene in the mouse by homologous recombination. Mice that lack Bcl-w were viable, healthy, and normal in appearance. Most tissues...
