WebJan 16, 2013 · Here we examined genes and proteins involved in hepatic oxidation and lipogenesis in 14-week-old leptin-deficient Ob/Ob mice, a commonly studied model of obesity and hepatic steatosis. Obese Ob/Ob mice had increased fasting glucose, insulin, and calculated HOMA-IR as compared with lean wild-type (WT) mice.

WebApr 1, 2001 · Fat accumulation is determined by the balance between fat synthesis (lipogenesis) and fat breakdown (lipolysis/fatty acid oxidation). Lipogenesis … WebJan 15, 1987 · The high rates of lipogenesis that occurred in the liver remnant were accompanied by an altered relationship between lipogenic rate and hepatic malonyl-CoA concentration, such that much lower concentrations of malonyl-CoA were associated with any given rate of lipogenesis.
WebThese observations suggest that liver-derived LCN13 regulates lipogenesis and fatty acid β oxidation in an autocrine/paracrine fashion. Because the liver cross-talks with other tissues, including adipose tissues, skeletal muscles and the brain, it will be interesting to study whether LCN13 regulates lipid metabolism and lipid levels in the ... WebApr 14, 2024 · Impaired mitochondrial fatty acid oxidation, reduction in mitochondrial quality, and disrupted mitochondrial function are associated with a decrease in the energy levels and impaired redox balance and negatively affect mitochondria hepatocyte tolerance towards damaging hits.
