Interleukin-6 contributes to early fasting-induced free fatty acid mobilization in mice.
Contracting muscle releases interleukin-6 (IL-6) enabling the metabolic switch from carbohydrate to fat utilization. Similarly, metabolism is switched during transition from fed to fasting state. Herein, we examined a putative role for IL-6 in the metabolic adaptation to normal fasting. In lean C57BL/6J mice, 6 h of food withdrawal increased gene transcription levels of IL-6 in skeletal muscle ...
متن کاملFasting-induced selective mobilization of brown adipose tissue fatty acids.
This study was conducted to determine whether there is selective mobilization of fatty acids from brown adipose tissue. Rats were fed a fish-oil diet and then fasted for 0, 7, or 10 days followed by analysis of the fatty acid content and composition of triacylglycerols (TAG) and phospholipid (PL) in interscapular brown adipose tissue (IBAT). Fatty acids were selectively lost from IBAT triacylgl...
متن کاملEffects of Ramadan fasting on plasma free fatty acids in patients with non-alcoholic fatty liver disease
Introduction: Nonalcoholic fatty liver disease (NAFLD) is a global disease which its prevalence is about 10-35%. Several factors are involved in the pathogenesis of the disease. The present study was conducted to evaluate the effect of fasting during Ramadan on plasma free fatty acids in patients with NAFLD.Methods: This cross-sectional study was performed during the month of Ramadan in June-Ju...
متن کاملImpaired amino acid metabolism contributes to fasting-induced hypoglycemia in fatty acid oxidation defects.
The importance of mitochondrial fatty acid β-oxidation (FAO) as a glucose-sparing process is illustrated by patients with inherited defects in FAO, who may present with life-threatening fasting-induced hypoketotic hypoglycemia. It is unknown why peripheral glucose demand outpaces hepatic gluconeogenesis in these patients. In this study, we have systematically addressed the fasting response in l...
متن کاملKeap1-Knockdown Decreases Fasting-Induced Fatty Liver via Altered Lipid Metabolism and Decreased Fatty Acid Mobilization from Adipose Tissue
AIMS The purpose of this study was to determine whether Nrf2 activation, via Keap1-knockdown (Keap1-KD), regulates lipid metabolism and mobilization induced by food deprivation (e.g. fasting). METHODS AND RESULTS Male C57BL/6 (WT) and Keap1-KD mice were either fed ad libitum or food deprived for 24 hours. After fasting, WT mice exhibited a marked increase in hepatic lipid accumulation, but Ke...
