β-catenin/ZEB1, β-catenin/ZEB1: Click to Expand ⟱
Source: HalifaxProj (inactivate)
Type:
β-catenin and ZEB1 are two important proteins that play significant roles in cancer biology, particularly in the processes of cell adhesion, epithelial-mesenchymal transition (EMT), and tumor progression.
β-catenin is a key component of the Wnt signaling pathway, which is crucial for cell proliferation, differentiation, and survival. It also plays a role in cell-cell adhesion by linking cadherins to the actin cytoskeleton.
Role in Cancer: ZEB1 is often upregulated in cancer and is associated with increased invasiveness and metastasis. It can repress epithelial markers (like E-cadherin) and promote mesenchymal markers (like N-cadherin and vimentin), facilitating the transition to a more aggressive cancer phenotype.

(MMP)-2 and MMP-9, which are the down-stream targets of β-catenin and play a crucial role in cancer cell metastasis.
