摘要
目的探讨雷公藤内酯醇(TP)诱导皮肤T细胞淋巴瘤Hut102细胞株的凋亡及机制。方法采用MTT法检测Hut102细胞的增殖抑制率,Annexin v-FITC/PI双染流式细胞术检测Hut102细胞的凋亡率,Western印迹法检测Hut102细胞中磷酸化p38丝裂原活化蛋白激酶(p38MAPK)、caspase-3、热休克蛋白27(Hsp27)的表达。结果雷公藤内酯醇可诱导Hut102细胞凋亡(P<0.01),磷酸化p38MAPK、caspase-3被激活,同时抑制Hsp27的表达。用p38MAPK特异性抑制剂SB203580干预后,雷公藤内酯醇诱导Hut102细胞凋亡率下降,磷酸化p38的表达降低,caspase-3激活被抑制,Hsp27的表达增加。结论雷公藤内酯醇可诱导Hut102细胞凋亡,该作用可被p38MAPK特异性抑制剂SB203580显著抑制,提示雷公藤内酯醇可能通过激活p38MAPK信号通路使部分Hut102细胞产生凋亡。
