Mitochondria are critical sources of hydrogen peroxide (H2O2), an important secondary messenger in mammalian cells. Recent work has shown that O2•-/H2O2 emission from individual sites of production in mitochondria is regulated by protein S ...

Rab1A Promotes Hepatic Steatosis by Suppressing Mitophagy via the Raf-1/ERK1/2/PINK1 Signaling Axis. [PDF]
Why does fat accumulate in the liver? Our study reveals Rab1A as the molecular switch that silences the cell's mitochondrial cleanup crew. Turning Rab1A off reactivates mitophagy, clears excess fat, and reverses fatty liver disease in mice—offering a promising new therapeutic target for MASLD, a growing global health challenge.

Contribution of mitochondria to injury of hepatocytes and liver tissue by hyperthermia
Objective: The aim of this study was to investigate functional changes of liver mitochondria within the experimentally modeled transition zone of radiofrequency ablation and to estimate possible contribution of these changes to the energy status of liver

The mitochondrion is one of the most important cellular organelles, and many drugs work by acting on mitochondria. Curcumin (Cur)-induced apoptosis of HepG2 in liver cancer cells is closely related to the function of inhibiting mitochondria. However, the

Potassium Metabolism of Liver Mitochondria.
SummaryRabbit liver mitochondria contain K which cannot be removed by repeated washings with NaCl solutions at 2°C. This K fraction exchanges with ambient K under appropriate metabolic conditions, indicating a dependence of K metabolism on aerobic oxidation. Orthophosphate depresses the mitochondrial K level.

Mitotherapy for Fatty Liver by Intravenous Administration of Exogenous Mitochondria in Male Mice
Mitochondrial dysfunction is a major and common mechanism in developing non-alcoholic fatty liver disease (NAFLD). Replacement of dysfunctional mitochondria by functional exogenous mitochondria may attenuate intrahepatic excessive lipid and recover ...

Protein phosphorylation in yeast mitochondria [PDF]
We describe the identification and submitochondrial localization of four protein kinases and of their target proteins in derepressed yeast mitochondria. The activity of one of the kinases depends on the presence of cyclic AMP (cAMP).
