Figure Lengend Snippet: Figure 3. Inhibition of focal adhesion proteins partially suppressed CS-induced cell columnarization (A) Western blotting results showing the effects of 10 μM PF228 (FAK inhibitor) treatment for 24 h on pFAK expression in MDCK cells under NS and CS conditions. (B) Representative images of cell junctions (center) and stress fibers (bottom) under NS and CS conditions with and without PF228 treatment. Dimethyl sulfoxide (DMSO) was used as the solvent control of PF228. Scale bar: 20 μm. (C and D) Quantification of the cell height and aspect ratio under NS and CS conditions and treatment with PF228. The quantification was based on mea- surements of 70–83 cells from 3 independent experiments (2-way ANOVA/Bonferroni correction). (E) Transverse and longitudinal sections of vinculin (VCL) expression under NS or CS conditions. Scale bar: 20 μm.
Article Snippet: MDCK cells were pretreated with 10 μM PF573228 (PF228) (Selleckchem, Houston, TX, USA) for 30 min before undergoing cyclic stretch experiments, during which the cells were continuously exposed to 10 μM PF228 for 24 h. Cell contractility was inhibited by treatment with 50 μM blebbistatin (BB) (Tocris Bioscience, Bristol, UK) for 30 min before and during 24 h of cyclic stretching.
