Lipid Peroxidation in Rat AH-130 Hepatoma Cells Enriched
Tumor cells generally display low lipid peroxidation. A low content of polyunsaturated fatty acids in membrane phospholipids is a possible cause of their decreased susceptibility to lipid peroxidation. To investigate the importance of substrate availability in eliciting lipid peroxidation and to study cell viability in conditions of stimulated lipid peroxidation, AH-130 hepatoma cells were enri...
متن کاملApoptosis induced by clofibrate in Yoshida AH-130 hepatoma cells: role of HMG-CoA reductase.
Clofibrate is a hypolipidemic drug belonging to the peroxisome proliferator (PP) family. PPs are well-recognized hepatocarcinogens, though only for rodents and not for humans. Their oncogenicity is usually ascribed to mitogenic or antiapoptotic action. However, we have reported that clofibrate can trigger fast and extensive apoptosis in rodent and human tumor cell lines. The present study exami...
متن کاملMarked hyperlipidaemia in rats bearing the Yoshida AH-130 ascites hepatoma.
Malignant tumour burden is a pathological s ta te associated with a considerable demand for nutrients by the growing tumour [l]. Although a great deal of work has been carried out, there are contradictory results about the effects of tumour burden on lipid metabolism both in experimental animals and man. Lipid oxidation has been reported either increased [2], unchanged [3] or decreased [4]. In ...
متن کاملMetabolic-independent volume changes and Mg++ binding in mitochondria isolated from AH-130 Yoshida ascites hepatoma.
The mitochondria isolated in isotonic sucrose from AH-130 Yoshida ascites hepatoma appear spontaneously swollen (11, 12). This spontaneous swelling may be in part responsible for the inability of tumor mitochondria to undergo extensive volume changes in hypotonie conditions or in conditions that induce large-amplitude, metabolic-dependent, or metabolic-independent swelling in normal liver mitoc...
متن کاملUranyl Acetate Induces Oxidative Stress and Mitochondrial Membrane potential collapse in the Human Dermal Fibroblast Primary Cells
Cytotoxicity of depleted uranium, as a byproduct of military has been came to spotlight in recent decades. DU is known as a chemical rather than radioactive hazard and efforts to illustrating its mechanism is undergo, but the precise complete molecular mechanisms are still unclear. Recent studies showed that uranium induces biological changes in many different target tissues, such as the kid...
