Background: Paraquat (PQ), as the most widely used herbicide in agriculture, induces poisoning in humans and animals mainly through oxidative stress. This study aimed to investigate the protective effects of nano-curcumin compared with curcumin against PQ-induced mitochondrial dysfunction. Materials and Methods: Thirty-six Wistar rats were used in this study. They were separated into 6 groups...

Fatigue is often described by patients as a lack of energy, mental or physical tiredness, diminished endurance, and prolonged recovery after physical activity. Etiologic mechanisms underlying fatigue are not well understood; however, fatigue is a hallmark symptom of mitochondrial disease, making mitochondrial dysfunction a putative biological mechanism for fatigue. Therefore, this review examin...

Striatal neuron death in Huntington's disease is associated with abnormal mitochondrial dynamics and functions. However, the mechanisms for this mitochondrial dysregulation remain elusive. Increased accumulation of Huntingtin-associated protein 40 (HAP40) has been shown to be associated with Huntington's disease. However, the link between increased HAP40 and Huntington's disease remains largely...

High levels of oxygen (hyperoxia) are often used to treat individuals with respiratory distress, yet prolonged hyperoxia causes mitochondrial dysfunction and excessive reactive oxygen species (ROS) that can damage molecules such as DNA. Ataxia telangiectasia mutated (ATM) kinase is activated by nuclear DNA double strand breaks and delays hyperoxia-induced cell death through downstream targets p...

Mitochondrial connexin 43 (Cx43) is important in cardioprotection by ischemic preconditioning; however, whether mitochondrial Cx43 is involved in mitochondrial dysfunction in the pathogenesis of dilated cardiomyopathy (DCM) remains to be elucidated. The present study was performed to investigate the changes in expression and the phosphorylation state of mitochondrial Cx43 in a rat model of DCM,...

OBJECTIVES In RA, synoviocytes cause increased oxidative stress, leading to mitochondrial alterations that may participate in the pathogenesis of RA. Here we investigated whether mitochondrial dysfunction induces inflammatory responses in cultured normal human synoviocytes, a hallmark of RA. METHODS Mitochondrial dysfunction was induced with the inhibitor oligomycin. The effects of mitochondr...

The neurobiological bases of mood instability are poorly understood. Neuronal network alterations and neurometabolic abnormalities have been implicated in the pathophysiology anxiety conditions associated with hence candidate mechanisms underlying its neurobiology. Fast-spiking parvalbumin GABAergic interneurons modulate activity principal excitatory neurons through their inhibitory action dete...

Myocardial mitochondria are the primary site of energy metabolism in heart. Thus, maintaining quality plays a vital role cardiovascular diseases. Mitochondrial control (MQC) mainly encompasses regulation mitochondrial dynamics, autophagy, and biogenesis. The pathogenic mechanisms abnormal features diseases remain complex, but understanding them may provide promising potential targets for discov...

Elaidic acid (EA) stimulation can lead to endoplasmic reticulum stress (ERS), accompanied by a large release of Ca2+, and ultimately the activation NLRP3 inflammasome in Kupffer cells (KCs). Mitochondrial instability or dysfunction may be key stimulating factors activate inflammasome, sustained Ca2+ transfer result mitochondrial dysfunction. We focused on KCs explore damag...

OBJECTIVES The purpose of this study was to test whether mitochondrial dysfunction is causative of sepsis sequelae, a mouse model of peritonitis sepsis induced by cecal ligation and perforation. Inhibition of mitochondrial permeability transition was achieved by means of pharmacological drugs and overexpression of the antiapoptotic protein B-cell leukemia (Bcl)-2. BACKGROUND Sepsis is the lea...
