(A) Graphic representation of real time RT-PCR results from 3–4 experiments for Claudin 7 (open bars), PAI-1 (light bars), and Caveolin-1 (dark bars) at both 10 and 37% stretch for 24h, normalized to 18S rRNA (*p<0.05 vs. no stretch). (B) Immunoblot densitometry, normalized to GAPDH (*p<0.05 vs. no stretch), and (C) representative immunoblot.
