Western blotting analysis of cytoskeleton regulatory protein expression. a Coloured bands of integrin signalling pathway-related proteins. b-d Expression levels of integrin, phosphorylated FAK397 (pFAK397), and phosphorylated Rac1/cdc42 (pRac/cdc42). The integrin expression (b) remained almost unchanged during the first 14 h of stretch, but started to decrease significantly at 20 h (p < 0.01). The expression of both pFAK397 (c) and pRac/cdc42 (d) was significantly up-regulated in the first 14 h of stretch (p < 0.05), but began to decrease at 20 h (p < 0.01)
