Maternal obesity can cause reduced oocyte quality and subfertility. Mitochondrial dysfunction plays a central role here, and most often inbred mouse models are used to study these pathways. We hypothesized that the mouse genetic background can influence the impact of high fat diet HFD -induced obesity on oocyte quality. HFD-mice had increased body weight gain, hypercholesterolemia, and increased oocyte lipid droplet LD accumulation in both strains. LD distribution was strain-dependent. In Swiss mouse oocytes, HFD significantly increased mitochondrial inner membrane potential MMP, reactive oxygen species concentrations, mitochondrial ultrastructural abnormalities by
It is generally agreed that individual genetic background and lifestyle factors contribute to the pathogenesis of this disorder. Both nutrition and physical activity are major factors in determining its manifestation, but the exact chain of causation remains unclear. Several rodent models have been used to study the pathogenesis of the metabolic syndrome. Models of acquired obesity generated by pharmacologic measures, such as the gold-thioglucose mouse model, certainly are unphysiologic in many respects. Subsequent studies have revealed that high-fat diets promote hyperglycemia and whole-body insulin resistance, and numerous researchers have examined their effects on muscle and liver physiology as well as insulin signal transduction. This has inevitably led to considerable variability in the results reported. Most studies have employed only one high-fat formula in contrast with standard chow and did not analyze the influence of the specific fat component in the model. Surprisingly, the role of monounsaturated fatty acids in this context remains to be defined.
