Low concentration of doxorubicin (0.05mg/l) was added in cultured cholangiocarcinoma cell line (QBC939). The expression of survivin was detected by RT-PCR and Western blot at 24h and 48h after adding doxorubicin.RESULTS:Survivin was expressed in 24 of 33 cholangiocarcinoma cases (72.7%).In contrast,no expression of survivin in adjacent noncancerous and benign bile duct lesions was observed (P<0.01). No correlation was found between survivin expression and clinical features.Doxorubicin could markedly (P<0.001) up-regulate survivin mRNA and protein expression of QBC939 cells.CONCLUSION:Overexpression of survivin in cholangiocarcinomas may play an important role in the development of cholangiocarcinoma, its relationship with prognosis of cholangiocarcinoma deserves further investigation. Higher expression of survivin is induced by doxorubicin in QBC939.Survivin expression may resist apoptosis induced by chemotherapy agents. 关 键 词:胆管上皮癌 阿霉素 细胞周期抑制素 免疫组织化学 化疗 细胞凋亡
