Antioxidant effect of 6-shogaol in UVA-irradiated HDFs. a 6-Shogaol treatment scavenged ROS in a dose-dependent manner. 6-Shogaol treatment also upregulated the expression of b SOD, c CAT, and d NRF2 mRNA in a dose-dependent manner. The graphs are combined from three independent experiments (mean ± S.D.). Student’s t test was conducted to determine statistical significance. *p < 0.05 compared with UVA-irradiated cells without 6-shogaol treatment; #p < 0.05 compared with negative controls that were not treated 6-shogaol or UVA irradiation
