The bcl-2 oncogene and apoptosis

D M Hockenbery. Semin Immunol. 1992 Dec.

Abstract

The bcl-2 oncogene is activated as a consequence of the t(14;18) chromosomal translocation in human follicular lymphomas. Bcl-2 functions to inhibit apoptosis in a variety of in vitro and in vivo experiments, suggesting interference with a central mechanism of apoptosis. The bcl-2 protein is associated with the inner mitochondrial membrane, however, the biochemical function of bcl-2 is unknown. Transgenic mice which overexpress bcl-2 provide evidence for bcl-2's role in memory B cells and thymic education as an intracellular survival factor. Additional regulators of apoptosis, such as the p53 tumor suppressor gene, may be altered in human cancers as one step in tumorigenesis.
