Liver cancer is a common malignant tumor with high mortality. Currently, effective medicines against liver cancer are still lacking. Paclitaxel is a wide-spectrum anti-tumor agent, while wilfortrine has been shown to have an inhibitory effect on the proliferation of liver cancer cells. This study thus investigated the potential effect of paclitaxel combined with wilfortrine on cultured liver cancer cells and related mechanisms, in order to provide evidence for pathogenesis and treatment of liver cancer.
MATERIAL/METHODS: Liver cancer cell line HpeG2 was divided into control, paclitaxel, wilfortrine, and combined treatment groups. Cell proliferation was tested by MTT, while invasion was detected in Transwell chamber assay. Apoptotic protein Bcl-2 and Bax expression levels were further quantified using real-time PCR and Western blotting.
Both of those 2 drugs can effectively inhibit cancer cell proliferation, depress invasion ability, increase Bcl-2 expression, and elevate Bax expression levels (p<0.05 in all cases). The combined therapy had better treatment efficacy compared to either of those drugs alone (p<0.05).
The combined treatment using wilfortrine and paclitaxel can inhibit proliferation and invasion of liver cancer cells via down-regulating Bcl-2 and up-regulating Bax, with better efficacy than single use of either drug.
肝癌是一种常见的恶性肿瘤,死亡率很高。目前,仍然缺乏有效的抗肝癌药物。紫杉醇是一种广谱抗肿瘤药物,而雷公藤春碱已被证明对肝癌细胞的增殖有抑制作用。因此,本研究探讨了紫杉醇联合雷公藤春碱对培养的肝癌细胞的潜在作用及其相关机制,以便为肝癌的发病机制和治疗提供依据。
材料/方法:将肝癌细胞系HpeG2分为对照组、紫杉醇组、雷公藤春碱组和联合治疗组。通过MTT法检测细胞增殖,采用Transwell小室实验检测细胞侵袭。使用实时PCR和蛋白质印迹法进一步定量凋亡蛋白Bcl-2和Bax的表达水平。
这两种药物均能有效抑制癌细胞增殖,降低侵袭能力,增加Bcl-2表达,并提高Bax表达水平(所有情况下p<0.05)。与单独使用这两种药物中的任何一种相比,联合治疗具有更好的治疗效果(p<0.05)。
雷公藤春碱与紫杉醇联合治疗可通过下调Bcl-2和上调Bax来抑制肝癌细胞的增殖和侵袭,其疗效优于单独使用任何一种药物。
