摘要(Abstract):

寻找促进神经干细胞增殖与分化的有效方法是加速神经干细胞临床应用的途径之一。该文分析了近十年来中外文献关于调控神经干细胞增殖分化的中药及其作用靶点与信号通路的报道,发现中药对神经干细胞增殖分化信号通路具有综合调控作用。第一,中药能通过Notch,PI3K/Akt,Wnt/β-catenin,GFs等信号通路影响神经干细胞的增殖与分化。(1)黄芪、淫羊藿、龟甲、远志能通过调节Notch信号通路中的关键蛋白或基因Notch1,NICD和Hes的表达起调控作用;(2)人参、银杏叶、丹参能通过介导PI3K/Akt信号通路发挥调控作用,但对该通路中上下游靶标的具体作用机制尚无研究;(3)姜黄、蛇床子可以上调Wnt/β-catenin信号通路中的关键靶蛋白Wnt3a及β-catenin的水平从而介导Wnt/β-catenin信号通路起调控作用;(4)三七、川芎可以通过促进分泌性生长因子EGF,b FGF等的表达发挥作用。第二,一些中药能通过多种途径诱导神经干细胞的增殖或分化:黄芪中的黄芪甲苷可以通过Notch信号通路调控神经干细胞的增殖或分化,但黄芪多糖含药血清又可以通过调节VEGF含量,活化PI3K/Akt信号通路发挥作用;淫羊藿中的淫羊藿苷和淫羊藿黄酮类可以分别介导Notch或GFs信号通路来控制神经干细胞的命运转化;人参皂苷Rg1可以通过Notch和PI3K/Akt信号通路发挥调控作用;银杏内酯B可通过激活PI3K/Akt信号通路、上调HIF-1α表达来有效调节神经干细胞凋亡相关基因和促进细胞增殖与分化,进而起到神经保护作用,而银杏叶提取物也能通过上调多种细胞因子的释放促进神经干细胞的增殖与分化;姜黄素可以通过Wnt/β-catenin与Notch信号通路来调控神经干细胞的增殖与分化。第三,信号通路的串话(cross-talk)是一些中药发挥促NSCs增殖与分化的重要途径。Notch与GFs信号通路、GFs与PI3K/Akt信号通路、Notch与Wnt/β-catenin信号通路等在调控神经干细胞的过程中相互协调,相互制约,在中药促进神经干细胞增殖或分化中发挥着关键的作用。中药对调控神经干细胞增殖分化信号通路的串话研究有待进一步加深,阐明其多靶点和多途径的作用机制与综合调控作用。
Since the discovery of neural stem cells(NSCs) in embryonic and adult mammalian central nervous systems,new approaches for proliferation and differentiation of NSCs have been put forward. One of the approaches to promote the clinical application of NSCs is to search effective methods to regulate the proliferation and differentiation. This problem is urgently to be solved in the medical field. Previous studies have shown that traditional Chinese medicine could promote the proliferation and differentiation of NSCs by regulating the relevant signaling pathway in vivo and in vitro. Domestic and foreign literatures for regulating the proliferation and differentiation of neural stem cells in recent 10 years and the reports for their target and signaling pathways were analyzed in this paper. Traditional Chinese medicine could regulate the proliferation and differentiation of NSCs through signaling pathways of Notch,PI3 K/Akt,Wnt/β-catenin and GFs. However,studies about NSCs and traditional Chinese medicine should be further deepened; the mechanism of multiple targets and the comprehensive regulation function of traditional Chinese medicine should be clarified.
