Effect of theophylline on UV irradiation–induced JNK phosphorylation and cell apoptosis. (A) Effect of theophylline (Theoph) on UV irradiation–induced JNK phosphorylation. (B) Effect of theophylline on UV irradiation–induced cell death. HCE cells were preincubated with theophylline at the indicated concentrations for 30 minutes and then exposed to UV irradiation. The cells were harvested for Western blot analysis 15 minutes after UV irradiation. Cell viability was tested by EB/AO staining 20 hours after UV exposure. Statistical significance was determined by Student’s t-test (P < 0.001, n = 6).
