  • Title: Multiple pathways of cytochrome c release from mitochondria in apoptosis.
    Author: Gogvadze V, Orrenius S, Zhivotovsky B.
    Journal: Biochim Biophys Acta; 2006; 1757(5-6):639-47. PubMed ID: 16678785.
    Abstract:
    Release of cytochrome c from mitochondria is a key initiative step in the apoptotic process, although the mechanisms regulating permeabilization of the outer mitochondrial membrane and the release of intermembrane space proteins remain controversial. Here, we discuss possible scenarios of the outer membrane permeabilization. The mechanisms by which the intermembrane space proteins are released from mitochondria depend presumably on cell type and on the nature of the apoptotic stimulus. The variety of mechanisms that can lead to outer membrane permeabilization might explain diversities in the response of mitochondria to numerous apoptotic stimuli in different types of cells.
