摘要:

目的:研究冬虫夏草(cordyceps sinensis)提取物对乙肝病毒X蛋白(hepatitis B virus X protein, HBx)诱导的人系膜细胞(human mesangial cells, HMCs)增殖和细胞外基质(extracellular matrix, ECM)积聚的作用及潜在机制。方法:用重组表达载体pCMV-HBx稳染人系膜细胞建立HBx过度表达模型,用空载体转染对照组。用MTT法和DNA合成法检测细胞增殖。蛋白质印迹法用于检测磷脂酰肌醇-3-激酶/蛋白激酶B(PI3K/Akt)信号通路相关蛋白和细胞外基质的表达。结果:HBx转染人系膜细胞可诱导系膜细胞增殖、基质积聚。HBx转染的HMCs可增强系膜细胞PI3K/Akt通路的活性,应用冬虫夏草可抑制这种作用。 结论:冬虫夏草可通过抑制PI3K/Akt信号通路减弱HBx诱导的人系膜细胞增殖和细胞外基质的产生。

Abstract:

AIM: To investigate the effect of C.sinensis extracts on HBx (Hepatitis B virus X protein) induced cell proliferation and extracellular matrix (ECM) accumulation and the underlying mechanism in cultured human mesangial cells (HMCs). METHODS: Human mesangial cells were stable transfected with pCMV-HBx to establish an HBx over-expression model, and a control group was transfected with an empty vector. Cell proliferation was determined by MTT assay and DNA synthesis assay. Western blotting was used to measure the expression of PI3K/Akt signaling pathway-related proteins and extracellular matrix.RESULTS: HBx transfection induced cell proliferation, matrix accumulation. HBx-transfected mesangial cells had increased activity of the PI3K/Akt pathways, and treatment with C.sinensis suppressed this effect. CONCLUSION: C.sinensis attenuates the HBx-induced human mesangial cell proliferation and matrix production in human mesangial cells via inhibition of the PI3K/Akt pathways.

Key words: cordyceps sinensis, proliferation, matrix accumulation, PI3K/Akt, HBx, human mesangial cells
