小檗碱抗肿瘤作用机制的研究进展

对近年来小檗碱抗肿瘤机制研究的最新进展进行总结,表明小檗碱可通过影响肿瘤细胞生长周期,抑制DNA和蛋白质的合成和影响拓扑异构酶活性来抑制肿瘤细胞增殖；通过调节凋亡相关基因的表达、诱导线粒体跨膜电位(△Φm)下降促进肿瘤细胞凋亡；通过抑制肿瘤血管形成、阻断肿瘤转移相关的信号传导通路、抗恶液质病等途径抑制肿瘤转移,另外小檗碱可通过诱导肿瘤细胞分化发挥抗肿瘤作用。

Advance on study in anti-tumor mechamism of bererine(Ber)

The article submitted the new progress of the study in antitumor mechanism of bererine (Ber). Reports indicated that Ber suppressed growth of tumor cells through impacting tumor cells growth cycle, inhibiting synthesises of DNA and protein, and reducing the activity of topoisomerase. Ber improved tumor cells apoptosis through several ways such as regulating apoptotic gene expression, inducing the decline of transmembrane potential on mitochondria. And Ber still could inhibit tumor metastasis through suppressing the formation of tumor angiogenesis, blocking signal transduction pathway, antagonizing extralumen, et al. In addition, Ber could induce tumor cells to differentiate to antagonize tumor.
