Induction of adipose S-100 protein release by free fatty acids in adipocytes.


The mechanism of S-100 protein release from adipocytes, which is apparently coupled with lipolytic activity, was investigated in vitro using rat epididymal fat pads. The S-100 protein release was increased severalfold by 10 microM epinephrine in the medium containing a low concentration (less than 5 mg/ml) of albumin, but the release was enhanced only… (More)
