Figure Lengend Snippet: Figure 10. (A,B) Representative confocal microscopy analysis of F-actin (Red) and integrin-β1 (green) distribution in MDA-MB-231 cells cultured under control conditions or treated with ZFEs for 96 h. Control cells exhibited a dense network of stress fibers (A). After ZFEs treatment, F-actin began to reorganize along the cell membrane, with lamellipodia and filopodia being nearly absent (B). Scale bars: 10 µm. (C,D) Representative confocal microscopy analysis of β-catenin (red) and E- cadherin (green) distribution in MDA-MB-231 cells cultured in control conditions or treated with ZFEs for 96 h. In untreated MDA-MB-231 cells, β-catenin was primarily localized in the cytosol and E-cadherin was completely absent (C). ZFEs treatment promoted the accumulation of β-catenin/E- cadherin complexes at the cell membrane, facilitating cell-to-cell contact and the reconstitution of an epithelial-like architecture (D). Scale bars: 20 µm.
Article Snippet: Finally, anti-integrin β1 antibody (sc8978 Santa Cruz, Dallas, TX, USA) was used with the secondary antibody goat anti-rabbit IgG Alexa Fluor® 488 (A11008; Invitrogen, Carlsbad, CA, USA) and Phalloidin TRITC labeled (P1951 Sigma-Aldrich–M.
