Molecular characterization of mitochondrial apoptosis-inducing factor
Mitochondria play a key part in the regulation of apoptosis (cell death). Their intermembrane space contains several proteins that are liberated through the outer membrane in order to participate inExpand

Bax and adenine nucleotide translocator cooperate in the mitochondrial control of apoptosis.
The proapoptotic Bax protein induces cell death by acting on mitochondria. Bax binds to the permeability transition pore complex (PTPC), a composite proteaceous channel that is involved in theExpand

Sequential reduction of mitochondrial transmembrane potential and generation of reactive oxygen species in early programmed cell death
Programmed cell death (PCD) is a physiological process commonly defined by alterations in nuclear morphology (apoptosis) and/or characteristic stepwise degradation of chromosomal DNA occurring beforeExpand

Essential role of the mitochondrial apoptosis-inducing factor in programmed cell death
Programmed cell death is a fundamental requirement for embryogenesis, organ metamorphosis and tissue homeostasis. In mammals, release of mitochondrial cytochrome c leads to the cytosolic assembly ofExpand

Mitochondrial control of nuclear apoptosis
Anucleate cells can be induced to undergo programmed cell death (PCD), indicating the existence of a cytoplasmic PCD pathway that functions independently from the nucleus. Cytoplasmic structuresExpand

Bcl-2 inhibits the mitochondrial release of an apoptogenic protease
Bcl-2 belongs to a family of apoptosis-regulatory proteins which incorporate into the outer mitochondrial as well as nuclear membranes. The mechanism by which the proto-oncogene product Bcl-2Expand

The Permeability Transition Pore Complex: A Target for Apoptosis Regulation by Caspases and Bcl-2–related Proteins
Early in programmed cell death (apoptosis), mitochondrial membrane permeability increases. This is at least in part due to opening of the permeability transition (PT) pore, a multiprotein complexExpand

Heat-shock protein 70 antagonizes apoptosis-inducing factor
Heat-shock protein 70 (Hsp70) has been reported to block apoptosis by binding apoptosis protease activating factor-1 (Apaf-1), thereby preventing constitution of the apoptosome, the Apaf-1/cytochromeExpand

The HIV-1 Viral Protein R Induces Apoptosis via a Direct Effect on the Mitochondrial Permeability Transition Pore
Viral protein R (Vpr) encoded by HIV-1 is a facultative inducer of apoptosis. When added to intact cells or purified mitochondria, micromolar and submicromolar doses of synthetic Vpr cause a rapidExpand

Mitochondrio‐nuclear translocation of AIF in apoptosis and necrosis
Apoptosis inducing factor (AIF) is a novel apoptotic effector protein that induces chro‐matin condensation and large‐scale (—50 kbp) DNA fragmentation when added to purified nuclei in vitro. ConfocalExpand
