Descripción
E‐cadherin, a central component of the adherens junction (AJ), is a single‐pass trans- membrane protein that mediates cell?cell adhesion. The loss of E‐cadherin surface ex- pression, and therefore cell?cell adhesion, leads to increased cell migration and invasion. Treatment of colorectal cancer (CRC)‐derived cells (SW‐480 and HT‐29) with 2.0 mM metformin promoted a redistribution of cytosolic E‐cadherin to de novo formed puncta along the length of the contacting membranes of these cells. Metformin also promoted translocation from the cytosol to the plasma membrane of p120‐catenin, another core component of the AJs. Furthermore, E‐cadherin and p120‐catenin colocalized with β‐catenin at cell?cell contacts. Western blot analysis of lysates of CRC‐derived cells revealed a substantial metformin‐induced increase in the level of p120‐catenin as well as E‐cadherin phosphorylation on Ser838/840, a modification associated with β‐catenin/ E‐cadherin interaction. These modifications in E‐cadherin, p120‐catenin and β‐catenin localization suggest that metformin induces rebuilding of AJs in CRC‐derived cells. Those modifications were accompanied by the inhibition of focal adhesion kinase (FAK), as revealed by a significant decrease in the phosphorylation of FAK at Tyr397 and paxillin at Tyr118. These changes were associated with a reduction in the numbers, but an increase in the size, of focal adhesions and by the inhibition of cell migration. Overall, these observations indicate that metformin targets multiple pathways associated with CRC development and progression.
