Mitochondrial permeability transition pore as a selective target for anti-cancer therapy
Mitochondrial outer membrane permeabilization (MOMP) is the ultimate step in dozens of lethal apoptotic signal transduction pathways which converge on mitochondria. One of the representative systems proposed to be responsible for the MOMP is the mitochondrial permeability transition pore (MPTP). Although the molecular composition of the MPTP is not clearly understood, the MPTP attracts much int...
متن کاملMitochondrial Permeability Transition Pore-as a Promising Target for Novel Neuroprotective Agents
Despite the differences in symptomatic pictures among Neurodegenerative Diseases (ND) all of them result in selective or generalized neuronal loss. The cascade of events leading to the neuronal death is multifactorial. The factors involved include metabolic disturbance, acidosis, excitotoxicity, oxidative stress, neuroinflammation, pathological aggregation of some proteins, and disregulation of...
متن کاملMitochondrial permeability transition pore as a target for cardioprotection in the human heart.
After an episode of myocardial ischemia, opening of the mitochondrial permeability transition pore (mPTP), at the onset of reperfusion, is a critical determinant of myocyte death. We investigated the role of the mPTP as a target for cardioprotection in the human heart. We subjected human atrial tissue, harvested from patients undergoing cardiac surgery, to a period of lethal hypoxia and investi...
متن کاملThe 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...
متن کاملPerspectives in Pharmacology Mitochondrial Permeability Transition Pore Opening as a Promising Therapeutic Target in Cardiac Diseases
In addition to their central role in ATP synthesis, mitochondria play a critical role in cell death. Oxidative stress accompanied by calcium overload, ATP depletion, and elevated phosphate levels induces mitochondrial permeability transition (MPT) with formation of nonspecific MPT pores (MPTP) in the inner mitochondrial membrane. Pore opening results in mitochondrial dysfunction with uncoupled ...
