Mitochondrial dysfunction and associated apoptosis have been reported in the pathogenesis of neuron degeneration. The effects of eicosapentaenoic acid (EPA) and arachidonic acid (AA) on the mitochondrial membrane potential, mitochondrial biogenesis, and mitochondrial function of rat C6 glioma cells were determined in this study. Increased cytochrome c release and activated caspase-3 expression ...

Immune cells have a remarkable influence on tissue homeostasis and stem cell function. Our study is focused how age-related immunometabolic alterations in T can affect fundamental dependent processes the skin, such as skin homeostasis, hair growth regeneration. To address this, we used Tfamfl/fl Cd4Cremouse model with severe mitochondrial dysfunction owing to lack of transcription factor A (Tfa...

BACKGROUND Mitochondrial DNA (mtDNA) copy number decreases in animal and human heart failure (HF), yet its role in cardiomyocytes remains to be elucidated. Thus, we investigated the cardioprotective function of increased mtDNA copy number resulting from the overexpression of human transcription factor A of mitochondria (TFAM) or Twinkle helicase in volume overload (VO)-induced HF. METHODS AND...

Background: Gamete cryopreservation is an inseparable part of assisted reproductive technology, and vitrification is an effective approach to the cryopreservation of oocytes. The aim of this study was to investigate vitrification effects on the expression levels of mitochondrial transcription factor A (Tfam) and mitochondrial-encoded cytochrome c oxidase subunit 1 (Cox1) in mouse metaphase II o...

Compelling evidence has demonstrated that arsenic (As) exposure is associated with kidney injuries. Given inflammatory responses and immune imbalances are the root causes of several diseases, this study investigated potential mechanisms underlying NLRP3 inflammasome activation in As-induced injury. A rat model sub-chronic As was established via oral administration NaAsO2. The results revealed u...

BACKGROUND FOXC2 has lately been implicated in diabetes and obesity as well as mitochondrial function and biogenesis and also as a regulator of mtTFA/Tfam. In this study, the expression of FOXC2 and selected genes involved in mitochondrial function and biogenesis in healthy subjects and in a matched cohort with type 2 diabetes patients before and after treatment with rosiglitazone was determine...

A change in mRNA stability alters the abundance of mRNA available for translation and is emerging as a critical pathway influencing gene expression. Variations in the stability of functional and regulatory mitochondrial proteins may contribute to the divergent mitochondrial densities observed in striated muscle. Thus we hypothesized that the stability of mRNAs encoding for regulatory nuclear an...
