Mean and standard error of the mean for serum concentrations of (A) leptin (top), (B) estradiol (bottom-left), and (C) progesterone (bottom-right) in female Syrian hamsters either fed ad libitum or food-restricted to 75% of their ad libitum intake for eight days. Terminal blood was collected from groups representing every day of the four-day estrous cycle. Plasma was analyzed for estradiol and progesterone by radioimmunoassay (RIA). Plasma was analyzed for leptin using an enzyme-linked immunosorbent assay (ELISA) kit. * = significantly different at P < 0.05.
