Abstract
The protooncogene bcl-2, which has been implicated in B-cell lymphoma development, inhibits apoptosis due to growth factor withdrawal in some, but not all, hematopoietic cells. Recently we found that bcl-2 also inhibits apoptosis in PC12 pheochromocytoma cells. We now report that bcl-2 inhibits the death of a central neural cell line due to serum and growth factor withdrawal, the calcium ionophore A23187, glucose withdrawal, membrane peroxidation, and, in some cases, free radical-induced damage. This broad range of protective effects of BCL-2 protein suggests that BCL-2 may interact with a central step in neural cell death. Measurements of intracellular free calcium suggest that BCL-2 alters the transduction of neural death signals at a point distal to the rise in intracellular free calcium.
