Wnt信号通路在细胞的分化、增殖和凋亡等生理过程中,以及在细胞癌变、肿瘤侵袭等病理过程中均发挥了重要的调控作用,已经成为细胞生物学和分子生物学研究的一大热点。 近年来,wnt信号通路的很多重要分子被一一发现,出现了大量的关于Wnt信号通路的研究报道。β-链蛋白(β—catenin)介导的信号通路是Wnt信号传导通路中的经典信号通路,尽管很多报道都介绍了Wnt/β-catenin信号通路中的分子机制,但由于研究者所选择的表达时间、采用的模式生物以及检测的作用位点等方面的不同,得到的研究结果也有很大差异,甚至出现完全相反的结果。
In recent years,Wnt/β-catenin signaling has been identified as a key player in embryogenesis and human diseases.Canonical Wnt signaling pathway is controlled by a variety of classic molecules like Wnt,β-catenin,Axin,APC,GSK-3β and CK1,which interact and coordinate to regulate the expressions of cell signaling molecules.The latest evidences suggest that some components of the Wnt/β-catenin signaling,like APC,GSK-3β,CK1,Dkk2 and WISE,play dual roles different from what they have been thought previously.Here we reviewed some recent discoveries on the canonical Wnt/β-catenin signaling pathway to provide some new ideas and principles for signaling transduction studies.
