Background and objectives: Beside its nutritional role, caper (Capparis spinosa) has long been used as an analgesic, anti-inflammatory, anti-diabetic and anti-cancer remedy. In the present study, we tested whether this plant can make effective changes in Sirt3 and mitochondrial function in colorectal carcinoma cell line since mitochondrial dysfunction has long been imp...
Multiple Sclerosis (MS) is a neurodegenerative and autoimmune disease that it’s molecular etiology and factors involving in its progression remains unknown. In this study for evaluation effect of mercuric on progression of MS we investigated the additive effect of mercuric sulfide on the brain mitochondrial dysfunction in experimental autoimmune encephalomyelitis (EAE) model of MS in C57BL/6 mi...
objective: the aim of the present study was to investigate the neuroprotective effects of melissa officinalis, a major antioxidant plant, against neuron toxicity in hippocampal primary culture induced by 3,4-methylenedioxymethamphetamine (mdma) or ecstasy, one of the most abused drugs, which causes neurotoxicity. materials and methods: 3-(4,5-dimethyl-2 thiazoyl)-2,5-diphenyl-tetrazolium bromid...
Mitochondrial functions include production of energy, activation of programmed cell death, and a number of cell specific tasks, e.g., cell signaling, control of Ca2+ metabolism, and synthesis of a number of important biomolecules. As proper mitochondrial function is critical for normal performance and survival of cells, mitochondrial dysfunction often leads to pathological conditions resulting ...
huntington disease (hd) is a genetically dominant condition caused by expanded cag repeats which code for glutamine in the hd gene product, huntingtin. huntingtin is expressed in almost all tissues, so abnormalities outside the brain can also be expected. involvement of nuclei and mitochondria in hd pathophysiology has been suggested. in fact, mitochondrial dysfunction is reported in brains of ...
in many models of programmed cell death, the mitochondrial protein aif translocates to the nucleus, where it induces the chromatin condensation and dna degradation. however, today it is well established that this flavoprotein is bifunctional. in addition to its lethal function in the nucleus of dying cells, aif plays a vital bioenergetic role in healthy ones by regulating mainly the activity of...
BACKGROUND Mitochondrial dysfunction has been associated with both human immunodeficiency virus (HIV) infection and exposure to antiretroviral therapy. Mitochondrial dysfunction has not been widely studied in HIV-infected children. We estimated the incidence of clinically defined mitochondrial dysfunction among children with perinatal HIV infection. METHODS Children with perinatal HIV infecti...
The contribution of mitochondrial dysfunction to insulin resistance is a contentious issue in metabolic research. Recent evidence implicates mitochondrial dysfunction as contributing to multiple forms of insulin resistance. However, some models of mitochondrial dysfunction fail to induce insulin resistance, suggesting greater complexity describes mitochondrial regulation of insulin action. We r...
INTRODUCTION Mitochondrial dysfunction has been postulated to participate in the development of many neuropsychiatric disorders, but there is no consensus as to its role. The aim of this paper is to review recent studies and to outline the current understanding of the association between mitochondrial dysfunction and psychiatric disorders. METHODOLOGY We reviewed articles that evaluated mitoc...
Mitochondrial dysfunction has been proposed to play a pivotal role in neurodegenerative diseases, including Alzheimer's disease (AD). To address whether mitochondrial dysfunction precedes the development of AD pathology, we conducted mitochondrial functional analyses in female triple transgenic Alzheimer's mice (3xTg-AD) and age-matched nontransgenic (nonTg). Mitochondrial dysfunction in the 3x...
