2. EMT 与 Wnt/β-catenin 通路. EMT 受多种信号通路调节,例如 TGF-β 、Wnt/β-catenin、 Hedgehog 和 Notch 信号通路 ,这些途径通过刺激 Snail 、 Twist 和 ZEB1/2 等转录因子来触发 EMT。在所有信号通路中,Wnt/β-catenin 通路在 EMT 的调控中发挥着关键作用[6]。 2.1 Wnt/β-catenin 的激活 ...
经典信号通路总结——Wnt信号通路 - 知乎 - 知乎专栏
简单来说,当细胞没有接受Wnt信号刺激时 (Wnt Off),细胞质内的Axin、APC和GSK3β形成毁灭复合体(destruction complex),与β-Catenin结合并使其被磷酸化后,最终通过泛素化修饰而降解。
Wnt/β-catenin-driven EMT regulation in human cancers - PMC
Among the different regulators of EMT, Wnt/β-catenin axis has been emerged as a versatile modulator. Wnt is in active form in physiological condition due to the function of GSK-3β that destructs β-catenin, while ligand–receptor interaction impairs GSK-3β function to increase β-catenin stability and promote its nuclear transfer.

Wnt/β-catenin signalling, epithelial-mesenchymal transition and ...
2024年6月1日 · Persistent Wnt/β-catenin signalling facilitates the epithelial-mesenchymal transition (EMT), which accelerates CRC invasion and metastasis. This review provides a summary of recent molecular studies on the role of the Wnt/β-catenin signalling axis in regulating EMT in CRC cells, which triggers metastatic pathogenesis.
EMT发生的分子机制之Wnt/β-catenin信号通路 - DXY.cn
2017年9月14日 · 研究显示,Wnt与其他信号通路相互整合,促进EMT的发生发展过程。 RTK/Ras/MAPK通路中的MAPK 和PI3K/ILK/PKB通路中的PKB均具有抑制GSK-3β活性的功能,因此这两条通路能够与Wnt/β-catenin信号通路共同作用于GSK-3β,上调Snail的水平,进而降低E-钙粘蛋白的表达,促进EMT的 ...

Signaling mechanisms of the epithelial-mesenchymal transition
Wnt Signaling in EMT. Wnt signals are transduced across the plasma membrane by Frizzled and low-density lipoprotein receptor–related protein (LRP) receptors.
Role of Wnt/beta-catenin signaling pathway in epithelial …
Our data suggests that activation of the Wnt/beta-catenin signaling pathway correlates with the characteristic of EMT and potency of invasiveness and proliferation. This may be the critical factor that directly controls the process of EMT induced by HIF-1alpha in prostate cancer cells.
