Effects and mechanisms of silibinin on human hepatoma cell lines

AIM To investigate in vitro effects and mechanisms of silibinin on hepatocellular carcinoma (HCC) cell growth. METHODS Human HCC cell lines were treated with different doses of silibinin. The effects of silibinin on HCC cell growth and proliferation, apoptosis, cell cycle progression, histone acetylation, and other related signal transductions were systematically examined. RESULTS We demonstrated that silibinin significantly reduced the growth of HUH7, HepG2, Hep3B, and PLC/PRF/5 human hepatoma cells. Silibinin-reduced HuH7 cell growth was associated with significantly upregulated p21/CDK4 and p27/CDK4 complexes, downregulated Rb-phosphorylation and E2F1/DP1 complex. Silibinin promoted apoptosis of HuH7 cells that was associated with down-regulated survivin and upregulated activated caspase-3 and -9. Silibinin's anti angiogenic effects were indicated by down-regulated metalloproteinase-2 (MMP2) and CD34. We found that silibinin-reduced growth of HuH7 cells was associated with increased activity of phosphatase and tensin homolog deleted on chromosome ten (PTEN) and decreased p-Akt production, indicating the role of PTEN/ PI3K/Akt pathway in silibinin-mediated anti-HCC effects. We also demonstrated that silibinin increased acetylation of histone H3 and H4 (AC-H3 and AC-H4), indicating a possible role of altered histone acetylation in silibininreduced HCC cell proliferation.CONCLUSION Our results defined silibinin's in vitro anti-HCC effects and possible mechanisms, and provided a rationale to further test silibinin for HCC chemoprevention.     

Silibinin Enhances Ultraviolet B-Induced Apoptosis in MCF-7 Human Breast Cancer Cells

Purpose

Chemotherapies for breast cancer generally have strong cellular cytotoxicity and severe side effects. Thus, significant emphasis has been placed on combinations of naturally occurring chemopreventive agents. Silibinin is a major bioactive flavonolignan extracted from milk thistle with chemopreventive activity in various organs including the skin, prostate, and breast. However, the mechanism underlying the inhibitory action of silibinin in breast cancer has not been completely elucidated. Therefore, we investigated the effect of silibinin in MCF-7 human breast cancer cells and determined whether silibinin enhances ultraviolet (UV) B-induced apoptosis.

Methods

The effects of silibinin on MCF-7 cell viability were determined using the MTT assay. The effect of silibinin on PARP cleavage, as the hallmark of apoptotic cell death, and p53 protein expression in MCF-7 cells was analyzed using Western blot. The effect of silibinin on UVB-induced apoptosis in MCF-7 cells was analyzed by flow cytometry.

Results

A dose- and time-dependent reduction in viability was observed in MCF-7 cells treated with silibinin. Silibinin strongly induced apoptotic cell death in MCF-7 cells, and induction of apoptosis was associated with increased p53 expression. Moreover, silibinin enhanced UVB-induced apoptosis in MCF-7 cells.

Conclusion

Silibinin induced a loss of cell viability and apoptotic cell death in MCF-7 cells. Furthermore, the combination of silibinin and UVB resulted in an additive effect on apoptosis in MCF-7 cells. These results suggest that silibinin might be an important supplemental agent for treating patients with breast cancer.     

水飞蓟宾胶囊预防抗结核药物肝损害的临床观察

[摘要]目的:探讨水飞蓟宾胶囊在结核病治疗中预防药物肝损害的价值。方法:我院2007年7月~2009年1月期间住院治疗112例肺结核患者,治疗组(47例)在采取抗结核方案基础上应用水飞蓟宾胶囊（70mg,口服,tid）护肝,对照组(65例)未应用水飞蓟宾胶囊,采取抗结核方案与治疗组相同,观察两组肝功能损害的情况。结果:抗结核治疗期间治疗组发生肝功异常比例明显低于对照组,两组比较有统计学差异(P<0.05)。治疗组发生肝功能异常停用抗结核药物给予保肝治疗,肝功能恢复正常平均时间低于对照组,两组比较有统计学差异（P<0.05）。结论:结核病患者在常规抗结核治疗的同时应用水飞蓟宾胶囊可以降低肝损害的发生率,发生肝损害的程度也可减轻。
