Dihydrocaffeic Acid Prevents UVB-Induced Oxidative Stress Leading to the Inhibition of Apoptosis and MMP-1 Expression via p38 Signaling Pathway

DHCA reduces UVB-induced ROS. L929 cells were treated with 35 μM DHCA or 1 mM NAC for 1 h, irradiated with UVB (600 mJ/cm2), and immediately after irradiation, intracellular ROS (a) and extracellular H2O2 (b) production were evaluated by H2DCFDA and Amplex Red kit assay, respectively. Each column represents the mean ± SD (). : significantly different from nonirradiated and nontreated cells (NC); and : significantly different from irradiated and nontreated cells (UVB).
