Abstract

Pterocephalus hookeri is a widely applied Tibetan medicinal prescription for treatment of diseases such as flu, rheumatoid arthritis, and enteritis in China. It has been reported that Pterocephalus hookeri has anti-inflammatory and analgesic actions. However, the antitumor activity of Pterocephalus hookeri remains unknown. In the present study, we demonstrate that n-butanol extracts of Pterocephalus hookeri (YSC-ZDC) has a strong antitumor activity against hepatoma carcinoma cell in vitro and in vivo. YSC-ZDC inhibited proliferation of all cancer cell lines and significantly inhibited Hep3B cells proliferation in a dose- and time-dependant manner. Transmission electron microscopy, hoechst 33258 staining, and flow cytometry analysis revealed that YSC-ZDC induced apoptosis in Hep3B cells. YSC-ZDC treatment dramatically inhibited PDK1 and Akt phosphorylation in Hep3B cells. Moreover, YSC-ZDC increased Bax expression and inhibited Bcl-2 expression. In addition, YSC-ZDC inhibited growth hepatoma xenografts in vivo with no effect on body weight and spleen index. Consistent with results in vitro, YSC-ZDC increased Bax expression and inhibited Bcl-2 expression in tumor tissue. Taken together, this study shows YSC-ZDC with an antitumor activity both in vitro and in vivo. Its mechanism underlying is related to blocking of the Akt pathway and regulation of Bcl-2 family proteins expression.

摘要

西藏棱子芹是一种在中国广泛应用于治疗流感、类风湿性关节炎和肠炎等疾病的藏药方剂。据报道,西藏棱子芹具有抗炎和镇痛作用。然而,西藏棱子芹的抗肿瘤活性尚不清楚。在本研究中,我们证明西藏棱子芹正丁醇提取物(YSC-ZDC)在体外和体内对肝癌细胞均具有较强的抗肿瘤活性。YSC-ZDC抑制所有癌细胞系的增殖,并以剂量和时间依赖性方式显著抑制Hep3B细胞的增殖。透射电子显微镜、Hoechst 33258染色和流式细胞术分析表明,YSC-ZDC诱导Hep3B细胞凋亡。YSC-ZDC处理显著抑制Hep3B细胞中PDK1和Akt的磷酸化。此外,YSC-ZDC增加Bax表达并抑制Bcl-2表达。此外,YSC-ZDC在体内抑制肝癌异种移植瘤的生长,对体重和脾脏指数无影响。与体外结果一致,YSC-ZDC增加肿瘤组织中Bax表达并抑制Bcl-2表达。综上所述,本研究表明YSC-ZDC在体外和体内均具有抗肿瘤活性。其潜在机制与阻断Akt通路和调节Bcl-2家族蛋白表达有关。
