摘要
磷脂酰肌醇-3-激酶/丝苏氨酸蛋白激酶(PI3K/AKT)信号转导通路作为细胞生长增殖的重要转导通路,在维持细胞恶性生物学特性中起重要作用。细胞在一系列内外因素的作用下,通过启动PI3K/AKT信号转导通路,诱导细胞的增殖、分化,避免细胞发生凋亡。近年来研究表明,PI3K/AKT信号转导通路在肿瘤细胞恶性增殖、血管新生和转移以及对放化疗的拮抗中起着重要作用。文章主要综述PI3K/AKT信号转导通路的结构特点,及其在乳腺癌转移与耐药中的作用。
The PI3K/AKT signal transduetion pathway is an inportant pathway in cell growth and prohferation,whieh plays an important role in keeping malignant bionomics of cells. Under a series of exterior and interior factors, cells proliferation and, differentiation can be, induced and cell apoptosis can be avoided by initiating PI3 K/ AKT pathway. Recent studies indicate that this pathway plays an important role in tumor cells proliferation, blood vessel neogenesis, tumor metastasis and resistance to chemotherapy and radiotherapy. This article mainly reviews the structure feature of PI3 K/AKT and its effect in metastasis and drug fast of breast cancer.
