Brain/gut peptides in fed and fasted rats.

abstract：:Fibroblast growth factor (FGF) 21, a unique, largely liver-derived endocrine member of the FGF superfamily, is often thought of as a fasting factor owing to its induction in rodents during starvation. However, FGF21 is not increased by fasting for periods of <7 days in humans; instead, it rises sharply after acute alc...

abstract：:The effect of fasting on hepatic endothelial lipase activity in the liver of adult rats was investigated. We found that, both in male and female rats, fasting produced a progressive decrease of the hepatic endothelial lipase activity. Upon refeeding, the activity returned to control values in 48 h. In isolated livers ...
