OBJECTIVE To our knowledge, this is the first published case report of an adolescent girl with a mitochondrial disorder and depression who displayed both new-onset psychotic and increased mood symptoms during treatment with risperidone. DATA A 16-year-old girl was treated with risperidone for mood lability and impulsivity at a community hospital. Within days, she developed paranoid ideation, ...

muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. one explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. in mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respirat...

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...

mitochondrial functions have a major impact on t-cell functionality. in this study we characterized whether mitochondrial function in the neonatal t-cells differs from that in the adult t-cells during short t-cell activation. methods: we used fow cytometry methods to test mitochondrial mass and to monitor mitochondrial ca2+ levels, mitochondrial potential and superoxide generation in parallel w...

Alpers-Huttenlocher syndrome (AHS) is an uncommon autosomal recessive mitochondrial DNA depletion disease. The classic clinical triad of progressive developmental regression, liver degeneration, and seizures helps define the disorder, but a wide range expressions occur. most common mutations in childhood have been identified cytochrome c oxidase Ⅰ Ⅳ genes. 7706G˃A missense mutation Cox Ⅱ gene w...

Intracellular calcium homeostasis disorder and mitochondrial dysfunction are involved in many acute and chronic brain diseases, including ischemic brain injury. An imbalance in mitochondrial fission and fusion is one of the most important structural abnormalities found in a large number of mitochondrial dysfunction related diseases. Here, we investigated the effects of mitochondrial division in...

BACKGROUND Chronic life stress, such as the stress of caregiving, can promote pathophysiology, but the underlying cellular mechanisms are not well understood. Chronic stress may induce recalibrations in mitochondria leading to changes either in mitochondrial content per cell, or in mitochondrial functional capacity (i.e., quality). METHODS Here we present a functional index of mitochondrial h...

Disrupted-In-Schizophrenia 1 (DISC1) is a candidate risk factor for schizophrenia, bipolar disorder and severe recurrent depression. Here, we demonstrate that DISC1 associates robustly with trafficking-protein-Kinesin-binding-1 which is, in turn, known to interact with the outer mitochondrial membrane proteins Miro1/2, linking mitochondria to the kinesin motor for microtubule-based subcellular ...

Mitochondria are crucial regulators of energy metabolism and apoptotic pathways and have been closely linked to the pathogenesis of neurodegenerative disorders. In this review we mainly focus on mitochondrial dysfunction in two of the most prevalent neurological disorders: Alzheimer's disease and Parkinson's disease. We discuss whether the role of mitochondria in those diseases should be consid...
