... of lipolysis and lipid oxidation and the downregulation of protein catabolism and synthesis. Consistent with a previously hypothesized diabetic-like fasting state, fasting was associated with elevated glucose and patterns of certain metabolites (e.g. citrate, cis-aconitate, myristoleic acid) indicative...

... dynamic pool of lipids, which can adjust to alterations in muscle energy supply and demand and can be modulated by both diet and exercise. Lipotoxicity PLIN5 PLIN2 Lipolysis Insulin sensitivity Dietary fatty acids are stored in adipose tissue. However, excess lipid intake leads...

.... Adipose tissue may display complementary but differing mechanisms to regulate lipolysis and re-esterification rates for the purpose of increasing fatty acid availability for milk synthesis. NES maintain high rates of lipolysis without ketoacidosis, in part, by maintaining high rates of glucose recycling...

...) in fasting rabbits. Our goals were to determine whether lipolysis is stimulated beyond values seen for short-term fasting, and to characterize the roles of primary (intracellular) and secondary (with transit through the circulation) triacylglycerol/fatty acid cycling (TAG/FA cycling) in regulating fatty acid...

... egg abandonment in fasting, incubating king penguins, lipolysis and NEFA availability are not depressed but are in fact increased. Thus, the phase III-associated refeeding signal that redirects behaviour from incubation towards the search for food does not appear to originate from a limited NEFA...

In spite of lower metabolic rates, thyroid hormone concentrations in captive manatees were comparable with those for other terrestrial...

Contrary to expectation, the rates of lipolysis and fatty acid release in resting trout are not affected by endurance exercise. Unlike mammals, which increase the rate...
