Zusammenfassung
Non-alcoholic fatty liver (NAFL) and ectopic lipid storage in skeletal muscle have been associated with insulin resistance and abnormal mitochondrial function in obesity and type 2 diabetes. The underlying causal relationships are yet unclear. The aim of this study was to determine the role of mitochondrial function during the development of lipid-induced NAFL and insulin resistance. We examined liver and muscle metabolism in 18- and 36-weeks-old female mice with secondary NAFL due to adipose tissue-specific overexpression of the sterol regulatory-element binding protein-1c (aP2-SREBP-1c: AP2; n=6–7) and in age-…
