摘要
Disturbed cardiac lipid homoeostasis in obesity is regarded as a key player in the development of cardiovascular diseases. in this study, we show that FAT (fatty acid translocase)/CD36-mediated LCFA (long-chain fatty acid) uptake in cardiac myocytes from young adult obese Zucker rats is markedly increased, but insensitive to insulin. Basal and insulin-induced glucose uptake rates in these myocytes are not changed, suggesting that during the development from obesity to hyperglycaemic Type 11 diabetes, alterations in cardiac LCFA uptake precede alterations in cardiac glucose uptake.
