Abstract:

〔Abstract〕 Objective: To investigate the effects of the 7-Hydroxyisoflavone on the proliferative activity of HaCaT cells and the UVB-induced photodamage, as well as its mechanism. Methods: The cell counting assay was used to detect the effects of different concentrations of 7-Hydroxyisoflavone on the proliferative activity of HaCaT cells. Next, the HaCat cells were pretreated with 200 μmol/L 7-Hydroxyisoflavone and were exposed to UVB(30 mJ/cm2). Then, the production of reactive oxygen species(ROS) was detected by fluorescence method. The expressions of PARP1 and Caspase-8 were detected by Western blot. Results:The 7-Hydroxyisoflavone had the most obvious effect on the proliferative activity of HaCaT cells at the concentration of 200 μmol/L, and it could reduce the production of UVB-induced ROS. Besides, it could also inhibit the expressions of the PARP1 and Caspase-8.Conclusion:The 7-Hydroxyisoflavone can reduce photodamage caused by UVB and has a photoprotective effect on cells, which can be used to prevent skin damage caused by UVB.
