PtdIns(4,5)P(2) has been indirectly implicated as a negative regulator of apoptosis ; however, it is unclear if apoptotic stimuli negatively regulate PtdIns(4,5)P(2) levels in vivo. Here, we show that two apoptotic-stress stimuli, hydrogen peroxide (H(2)O(2)) and UV irradiation, cause PtdIns(4,5)P(2) depletion during programmed cell death independently of and prior to caspase activation. Depletion of PtdIns(4,5)P(2) is essential for apoptosis because maintenance of PtdIns(4,5)P(2) levels by overexpression of PIP5Kalpha rescues cells from H(2)O(2)-induced apoptosis. PIP5Kalpha expression promotes both basal and sustained ERK1/2 activation after H(2)O(2) treatment, and importantly, pharmacological inhibition of ERK1/2 signaling blocks PIP5Kalpha-mediated cell survival. H(2)O(2) induces tyrosine phosphorylation and translocation of PIP5Kalpha away from its substrate at the plasma membrane, and both are dependent upon the activity of c-src family kinases. Furthermore, constitutively active c-src enhances tyrosine phosphorylation of PIP5Kalpha in vivo and is sufficient for the translocation of PIP5Kalpha away from the plasma membrane. These observations demonstrate that certain apoptotic stimuli initiate an essential signaling pathway during cell death, and this pathway leads to caspase-independent downregulation of PIP5Kalpha and its product PtdIns(4,5)P(2)."xsd:string |
