WebHere we show, using a pH-sensitive green fluorescent protein (GFP), that mitochondria-dependent apoptotic stimuli (such as Bax, staurosporine and ultraviolet irradiation) induce rapid, Bcl-2-inhibitable mitochondrial alkalinization and cytosol acidification, followed by cytC release, caspase activation and mitochondrial swelling and depolarization. WebJun 9, 1998 · The in vitro pH dependency of various GFP mutants has been reported recently (9, 10). Here we extend these observations to other GFP mutants with improved properties as pH probes. We target these GFPs to the cytosol plus nucleus, trans-Golgi cisternae, and mitochondrial matrix to study pH regulatory mechanisms in these organelles in living cells.
