【摘要】:目的:探讨绞股蓝总皂苷对紫外线照射的人皮肤相关原癌基因c-Fos和c-Jun表达的影响。方法:制备空白大鼠血清和绞股蓝含药血清。将人永生化角质形成细胞(human immortal skin keratinocytes,HaCaT)40瓶随机分为4组(A~D组),每组10瓶,将人皮肤成纤维细胞(human skin fibroblast,HSF)60瓶随机分为6组(Ⅰ~Ⅵ组),每组10瓶。分别用中波紫外线(ultraviolet B,UVB)对HaCaT细胞B~D组、用长波紫外线(ultraviolet A,UVA)对HSF细胞Ⅱ~Ⅵ组进行照射。将HaCaT 4组细胞培养上清液分别加入HSF细胞的Ⅲ~Ⅵ组。最终制成用于检测的6组细胞,分别为空白对照组(Ⅰ组)、UVA模型组(Ⅱ组)、HaCaT培养上清液A组(Ⅲ组)、HaCaT培养上清液B组(Ⅳ组)、HaCaT培养上清液C组(Ⅴ组)、HaCaT培养上清液D组(Ⅵ组)。采用反转录聚合酶链反应(reverse transcription-PRC,RT-PCR)和蛋白免疫印迹(Western blot)方法检测Ⅰ~Ⅵ组细胞cFos和c-Jun基因和蛋白的表达水平。结果:与Ⅰ组比较,Ⅱ组细胞c-Fos和c-Jun基因和蛋白的表达水平明显上调(各组P值均为0.000);与Ⅱ组比较,Ⅳ组c-Fos和c-Jun基因和蛋白表达均上调(Pc-Fos基因=0.016、Pc-Fos蛋白=0.001、Pc-Jun基因=0.005、Pc-Jun蛋白=0.000),而Ⅲ组变化不明显;与Ⅳ组比较,Ⅵ组c-Fos和c-Jun基因和蛋白表达均下调(各组P值均为0.000),而Ⅴ组变化不明显(Pc-Fos基因=0.081、Pc-Fos蛋白=0.088、Pc-Jun基因=0.109、Pc-Jun蛋白=0.026)。结论:经UVB照射的HaCaT细胞分泌细胞因子促进经UVA照射的HSF细胞原癌基因c-Fos和c-Jun基因和蛋白的表达。绞股蓝总皂苷对UVB照射HaCaT细胞培养上清液作用的UVA照射HSF细胞中原癌基因c-Fos和c-Jun的表达具有抑制作用。
