摘要:

[摘要] 目的:探讨7-羟基异黄酮对HaCaT细胞的增殖活性和中波紫外线(UVB)诱导光损伤的影响及作用机制。方法:通过细胞计数法检测不同浓度7-羟基异黄酮对HaCaT细胞增殖活性的影响;用200 μmol/L 7-羟基异黄酮预处理HaCaT细胞后给予30 mJ/cm2 UVB照射,荧光法检测活性氧(ROS)生成量,用蛋白质印迹法检测细胞凋亡相关蛋白聚ADP-核糖聚合酶1PARP1)和半胱氨酸蛋白酶-8Caspase-8)的表达。结果:200 μmol/L 7-羟基异黄酮对HaCaT细胞增殖活性作用最明显,可降低UVB诱导的ROS生成量,抑制PARP1Caspase-8的表达。结论:7-羟基异黄酮能减轻UVB所致的光损伤,对细胞具有光保护作用,可预防UVB造成的皮肤损伤。

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 UVB30 mJ/cm2. Then the production of reactive oxygen speciesROS was detected by fluorescence method. The expressions of PARP1 and Caspase-8 were detected by Western blot. ResultsThe 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.ConclusionThe 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.
