Serum starved Y1 cells were stimulated with either 1 nM of N-POMC1–28 (A) or N-POMC1–49 (B) for various times. Cell lysates were analyzed by immunoblotting with antibodies against total p44/42 ERK and phospho p44/42 ERK. Band intensities are normalized to those of the total amount of either p44 or p42 ERK and expressed as the mean (±S.E.M.) of three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001 relative to value at 0 min.
