mitochondria play key roles in many cell functions including energy production, fatty acid metabolism, pyrimidine biosynthesis, calcium homeostasis, and aging. they also regulate crucial signaling cascades such as apoptosis and oxidative stress. the proteome is often used to investigate the functional correlations on protein levels. based upon the human, genome there is estimated 2000 to 2500 a...

objective(s): to understand the role of mitochondrial respiration in cisplatin sensitivity, we have employed wild-type and mitochondrial dna depleted rho0 yeast cells. materials and methods: wild type and rho0 yeast cultured in fermentable and non-fermentable sugar containing media, were studied for their sensitivity against cisplatin by monitoring growth curves, oxygen consumption, ph changes ...

oxidative stress and mitochondrial dysfunction are the main suggested mechanisms for neurodegenerative diseases. in this study, we have evaluated the effects of epicatechin (ec) on mitochondrial damage induced by homocycteine (hcy) using isolated rat hippocampus mitochondria in vivo . ec (50 mg/kg) was gavaged daily for a period of 10 days, starting 5 days prior to hcy (0.5 μmol/μl) intra hippo...

prohibitins are chaperone proteins highly conserved among eukaryotes. many different functions have been attributed to prohibitins depending on their tissue expression and sub-cellular localization. prohibitins play a major role in mitochondrial physiology, regulating the stability and the processing of both respiratory chain complex subunits and opa1, a mitochondrial fusion regulating protein....

multiple sclerosis (ms) is a chronic inflammatory demyelinating disease of the central nervous system that inflammation, demyelination, oligodendrocyte loss, gliosis, axonal injury and neurodegeneration are the main histopathological hallmarks of the disease. although ms was classically thought as a demyelinating disease, but axonal injury occurs commonly in acute inflammatory lesions. in ms mi...

Background: Although the bio kinetics, metabolism and chemical toxicity of Atorvastatin are well known, until recently little attention was paid to the potential neurotoxic effect of Atorvastatin (Atv). Regarding the concrete evidences indicating Atv may reduce Coenzyme Q10 (CoQ10) levels through blockage of  metalonate cycle, the present work aims to determine if Atorvastatin may provide toxic...

The health risks associated with outdoor air pollution are of global concern. Atmospheric negatively affects a number key aspects human health, including the functioning respiratory, cardiovascular and central nervous systems, but many issues remain unresolved about relationship between atmospheric development course pathologies. review analyzes data from Russian foreign sources on effect parti...

The concerns about the possible risk of manufactured nanoparticles (NPs) have been raised recently. Nano- and micro-sized copper oxide (CO and CONP) are widely used in many industries. In this regard, in-vitro studies have demonstrated that CONP is a toxic compound in different cell lines. Despite their unique properties, NPs possess unexpected toxicity profiling relative to the bulk m...

Viruses are known to hijack the intracellular organelles, including mitochondria, endoplasmic reticulum, lipid droplets, and cytoskeleton promote its replication. The host responds invading viruses by mounting antiviral responses rearrangement of organelles. In particular, mitochondria one target organelles exploited their proteins suppress response. this review, we have comprehensively summari...
