The mitochondrial permeability transition pore.
This chapter reviews recent advances in the identification of the structural elements of the permeability transition pore. The discovery that cyclosporin A (CsA) inhibits the pore proved instrumental. Various approaches indicate that CsA blocks the pore by binding to cyclophilin (CyP)-D. In particular, covalent labelling of CyP-D in situ by a photoactive CsA derivative has shown that pore ligan...

This paper reports on the results of a survey conducted within the Department of Design and Technology, Loughborough University, UK, in response to increasing concern over the quality and effective use of 2D modelling by design undergraduates at all levels. A survey, in the form of a questionnaire supported by ongoing tutorials, was conducted in an attempt to establish the underlying reasons wh...
متن کاملp53 Opens the Mitochondrial Permeability Transition Pore to Trigger Necrosis
Ischemia-associated oxidative damage leading to necrosis is a major cause of catastrophic tissue loss, and elucidating its signaling mechanism is therefore of paramount importance. p53 is a central stress sensor responding to multiple insults, including oxidative stress to orchestrate apoptotic and autophagic cell death. Whether p53 can also activate oxidative stress-induced necrosis is, howeve...
متن کاملErratum to: The Mitochondrial Permeability Transition Pore and ATP Synthase.
Mitochondrial ATP generation by oxidative phosphorylation combines the stepwise oxidation by the electron transport chain (ETC) of the reducing equivalents NADH and FADH2 with the generation of ATP by the ATP synthase. Recent studies show that the ATP synthase is not only essential for the generation of ATP but may also contribute to the formation of the mitochondrial permeability transition po...
متن کاملMitochondrial permeability transition pore: an enigmatic gatekeeper
Mitochondrial permeability transition pore (MPTP) is a transient structure formed in the inner mitochondrial membrane (IMM) upon oxidative challenge of the organelle. The transition is a Ca 2+ -dependent increase of permeability of IMM leading to loss of transmembrane potential (∆ψm), mitochondrial swelling and, finally, rupture of outer mitochondrial membrane leading to release of factors caus...
