Megamitochondria were induced within 36-40 hours in mouse hepatocytes by injecting cuprizone into the peritoneal cavity. Induction of megamitochondria was dependent upon the amount and the time intervals of the injection of cuprizone: 200 mg of cuprizone/kg of body weight-injected every 12 hours or 400 mg of cuprizone/kg of body weight-injected every 24 hours. When the latter amount of the noxious reagent was administered to the animal every 12 hours, fatty changes of the liver was observed. Involvement of the fusion phenomenon in the mechanism of megamitochondrial formation is discussed in the light of turnover rates for various components of the mitochondrion.

UI MeSH Term Description Entries
D008297 Male Males
D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.
