Multiple pathway analysis in HaCaT cells exposed to resveratrol, UVB or both: earlier time point (15 minutes).

<p>HaCaT cells were pretreated with 25 and 100 µM resveratrol for 2 and 24 hours prior irradiation with UVB (10, 40, and 100 mJ/cm²). Cell lysates were collected 15′ after UVB irradiation. Phosphorylated or not phosphorylated protein levels were analyzed by western blot. The figure shows representative blots analyzing the levels of the phosphorylated forms of ERK1/2, p38, p53, AKT, and S6, and the levels of BAX, and Bcl2.GAPDH was used as loading control.
