Since its discovery in the 1970s, the mitochondrial permeability transition (MPT) has been proposed to be a strategic regulator of cell death. Intense research efforts have focused on elucidating the molecular components of the MPT because this knowledge may help to better understand and treat various pathologies ranging from neurodegenerative and cardiac diseases to cancer. In the case of canc...

Cyclosporin A (CsA) shows cytoprotective properties in many cellular and in vivo models that may depend on interference of the interaction of cyclophilin A with calcineurin or of cyclophilin D with the mitochondrial permeability transition (PT) pore. The nonimmunosuppressive cyclosporin derivative N-methyl-4-valine-cyclosporin (PKF220-384) inhibits the mitochondrial permeability transition (MPT...

An increase in the permeability of outer mitochondrial membrane is central to apoptotic cell death, and results in the release of several apoptogenic factors such as cytochrome c into the cytoplasm to activate downstream destructive programs. The voltage-dependent anion channel (VDAC or mitochondrial porin) plays an essential role in disrupting the mitochondrial membrane barrier and is regulate...

We have studied biochemical changes occurring in brain cell mitochondria of white rats on the background of stress induced by 30-day isolation and disruption of circadian rhythms. It was ascertained that due to long-lasting stress, there occurs activation of oxidative processes in mitochondria as well as inhibition of anti-oxidant system activity, causing development of energy deficiency in bra...

Clinical use of nonsteroidal anti-inflammatory drugs (NSAIDs) like diclofenac (DCLF) is limited by multiple adverse effects, including renal toxicity leading to acute kidney injury. In mice with DCLF-induced nephrotoxicity, TDZD-8, a selective glycogen synthase kinase (GSK)3β inhibitor, improved acute kidney dysfunction and ameliorated tubular necrosis and apoptosis associated with induced cort...

Excitotoxicity, oxidative stress, and mitochondrial dysfunction are associated with autism. Considering the preventive role of complement 1q binding protein or olesoxime for the opening of mitochondrial permeability transition pore mediated by oxidative stress, it is hypothesized that complement 1q binding protein or olesoxime may improve some symptoms of autism.
