By postmortem biochemical and molecular genetic analyses, an 8-month-old infant was diagnosed with long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency, an inborn error of mitochondrial fatty acid beta-oxidation. He was born following a pregnancy complicated by a maternal floor infarction of the placenta, a disorder of unknown etiology. We speculate that the child's autosomal recessive ...
arsenic exposure mainly through food and water has been shown to be associated with increased incidence of numerous cancers and non-cancer harmful health. it is also used in cancer chemotherapy and treatment of several cancer types due to its apoptogenic effects in the various cancer and normal cell lines. we have already reported that liver is the storage site and important target organ in as ...
sepsis is a systemic inflammatory response to infection. sepsis, which can lead to severe sepsis, septic shock, and multiple organ dysfunction syndrome, is an important cause of mortality. pathogenesis is extremely complex. in recent years, cell hypoxia caused by mitochondrial dysfunction has become a hot research field. sepsis damages the structure and function of mitochondria,conversely, mito...
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...
BACKGROUND Mitochondrial dysfunction and defects in oxidative metabolism are a characteristic feature of many chronic illnesses not currently classified as mitochondrial diseases. Examples of such illnesses include bipolar disorder, multiple sclerosis, Parkinson's disease, schizophrenia, depression, autism, and chronic fatigue syndrome. DISCUSSION While the majority of patients with multiple ...
Mitochondrial DNA (mtDNA) is highly polymorphic, and its variations in humans may contribute to individual differences in function as well as susceptibility to various diseases such as Parkinson disease, Alzheimer disease, bipolar disorder, and cancer. However, it is unclear whether and how mtDNA polymorphisms affect intracellular function, such as calcium signaling or pH regulation. Here we se...
Lithium (Li) is still useful in the treatment of bipolar disorder. Cellular mechanisms of Li action are not fully understood and include some cytoprotective properties. Data concerning Li effect on the apoptotic mechanisms in cells other than neurons are fragmentary and contradictory. We have investigated anti-apoptotic activity of Li in a lymphoid derived MOLT-4 cell line. Spontaneous and camp...
BACKGROUND Coronary heart disease is the leading cause of death worldwide. Mitochondrial genetic determinants for the development of this disorder remain less explored. METHODS AND RESULTS We performed a clinical and genetic evaluation and mutational screening of 22 mitochondrial tRNA genes in a cohort of 80 genetically unrelated Han Chinese subjects and 125 members of 4 families with coronar...
Resistance to thyroid hormone (RTH), a dominantly inherited disorder usually associated with mutations in thyroid hormone receptor beta (THRB), is characterized by elevated levels of circulating thyroid hormones (including thyroxine), failure of feedback suppression of thyrotropin, and variable tissue refractoriness to thyroid hormone action. Raised energy expenditure and hyperphagia are recogn...
We studied the physiometabolic effects of a mitochondrial DNA (mtDNA) heteroplasmic point mutation, the A Gtransition associated with maternally inherited myopathy and cardiomyopathy. To eliminate the possible influence of the autochthonous nuclear gene set, we fused myoblast-derived cytoplasts of a patient with a human tumoral cell line deprived of mtDNA (Rho0). The presence and amount of the ...
