Mitochondria dysfunction was first described in the 1960s. However, the extent and mechanisms of mitochondria dysfunction's role in cellular physiology and pathology has only recently begun to be appreciated. To adequately evaluate mitochondria-mediated toxicity, it is not only necessary to understand mitochondria biology, but discerning mitochondrial redox biology is also essential. The latter...

acrolein (acr) is α, β unsaturated aldehyde that exists extensively in the environment and (thermally processed) foods. it can also be generated through endogenous metabolism. the aim of this study was to investigate the possible protective role of pentoxifylline (ptx) is a non-selective phosphodiesterase (pde) inhibitor on toxicity of acr. in this study, oxidative damage were measured by marke...

mitochondria are unique organelles with major role in cellular function, not only as a major site of atp production, but also by regulating energy expenditure, apoptosis signaling, and production of reactive oxygen species. they play a central role in determining the point-of-no-return for the apoptotic process. there is accumulating evidence supporting a direct link between mitochondria, oxida...

Emerging line research showed that silk nanoparticles (NPs) have toxicity on the fibroblastand Huvec cells without any toxicity recognized mechanisms. Recently, it suggested peripheralarterial disease confounds almost eight million Americans. Also, due to the main effect offibroblast in a production of extracellular matrix (ECM), adhesive molecules, glycoproteinsand various cytokines, it decide...

OBJECTIVES Manganese chloride (MnCl(2)) is one of heavy metals for causing neurogenerative dysfunction like Manganism. The purpose of this study was to determine the acute toxicity of MnCl(2) using different times and various concentrations including whether manganese toxicity may involve in two intrinsic pathways, endoplasmic reticulum (ER) stress and mitochondria dysfunction and lead to neuro...

TDP-43 protein is found deposited as inclusions in the amyotrophic lateral sclerosis (ALS) patient's brain. The mechanism of neuron death ALS not fully deciphered but several toxicity mechanisms such mis-regulation autophagy, mitochondrial impairment and generation oxidative stress etc., have been implicated. A predominantly nuclear protein, Cyclin C, can regulate response via transcription gen...

Iron is an essential transition metal for its involvement in several crucial biological functions, the most notable being oxygen storage and transport. Due to high reactivity potential toxicity, intracellular extracellular iron levels must be tightly regulated. This achieved through transport systems that mediate cellular uptake efflux both at level of plasma membrane on membranes lysosomes, en...

Pioglitazone (PG) is one of thiazolidinediones used for the treatment of type II diabetes mellitus. Some reports of its hepatotoxicity exist, but the mechanism of its hepatotoxicity is not well known. In the present study, the protective effect of some ATP suppliers are investigated against mitochondrial toxicity of PG in isolated rat mitochondria. Mitochondrial viability was investigated by MT...
