Figure 4. Resveratrol inhibits p38 and JNK phosphorylation. HLEB-3 cells were treated with 100 μM H₂O₂ with or without 20.0 μM resveratrol for intervals ranging between 1 and 3 h and p38 and JNK activities were evaluated by western blotting analysis using anti-phosphorylated p38 and anti-phosphorylated JNK antibodies. Resveratrol significantly inhibited p38 and JNK phosphorylation compared to control. Anti-p38 and anti-JNK protein antibodies show equal loading of protein samples.
