摘 要:肿瘤干细胞是一类具有自我更新分化能力,在移植动物宿主中具有致瘤性且对放化疗抵抗的细胞小亚群,是肿瘤复发转移的主要原因。Notch信号通路在进化中高度保守,具有调控细胞增殖、分化和凋亡的功能,且在维持肿瘤干细胞的干细胞特性方面发挥重要作用,在干细胞中与多个信号通路存在交互作用。通过抑制Notch信号通路靶向作用肿瘤干细胞的治疗策略已进入临床试验阶段,具有广阔的发展前景。全文就Notch信号通路在肿瘤干细胞中的作用及其与Wnt、TGF-β、Her-2信号通路的交互作用进行阐述与分析。 |

Abstract:Cancer stem cells (CSCs) are a small subset of cells characterized by their ability to self-renew and differentiate,to generate a tumor when transplanted into an immune-deficient animal and to be resistant to chemo- and/or radiation- therapy,indicating the main reason for cancer relapse and metastasis. The Notch signal pathway,a strong evolutionary conservation pathway,has many functions including regulating cell proliferation,differentiation,cell death,cell fate determination and maintaining stem like characteristic of CSCs. It exists cross-talk between Notch and other pathways in stem cells. The progress in therapy of targeting the CSCs by inhibiting the Notch signal pathway has developed into the step of clinical trial research and a bright future can be seen. The purpose of this review is to explain and analyze the function of Notch signal pathway in CSCs and cross-talk between Notch signal pathway and Wnt,TGF-β,Her-2 signal pathways. |
