Bcl-2 and Bax mammalian regulators of apoptosis are functional in Drosophila

Résumé

Studies of apoptosis in C. elegans have allowed the identification of three genes, ced-3, ced-4 and ced-9. Their products constitute the components of an induction pathway of apoptosis conserved in the nematode and mammals. In Drosophila, homologues have been found for CED-3, CED-4 and CED-9. CED-9 belongs to the Bcl-2 family which includes negative (Bcl-2) and positive (Bax) regulators of apoptosis. The recently discovered Bcl-2 family member named Drob-1 acts as a positive regulator of cell death. To address whether a Bcl-2 anti-apoptotic pathway exists in the fly, we studied the effects of expressing the mammalian genes bcl-2 in Drosophila. In embryos, expression of bcl-2 inhibits developmental and X-ray-induced apoptosis. Expressing bcl-2 or the pro-apoptotic mammalian bax in the developing eye and wing alters these structures, bcl-2 increasing the number of cells, while bax reduces the number of cells. In addition, the functional interaction between Bcl-2 and Bax is conserved. These results indicate that factors necessary for the activity of bcl-2 and bax are present in Drosophila. Therefore, a Bcl-2 pathway for inhibition of cell death may exist in the fly. Cell Death and Differentiation (2000) 7, 804 ± 814.
