Overexpression UT stimulated fibroblast activation to myofibroblasts in primary cultured cardiac fibroblasts. (A, B & C) cultured fibroblasts treated with adenovirus to overexpress UT. Quantitative mRNA expression in these cells performed by real-time PCR. All gene expressions were calculated by ΔΔcq and standardized by housekeeping gene 18s. A, Renin; B, Ace (angiotensin-converting enzyme); and C, Agtr1: angiotensin II receptor type1. D, Primary cultured cardiac fibroblasts transduced with Ad-UT for 48 hours. Western blot of lysates were performed for α-SMA and TGF. The point graphs show the levels of each protein comparing in arbitrary units. Protein level normalized by total protein density of Ponceau S staining. All data: mean ± SEM (N = 4-6). *P < .05, **P < .005 by one-way ANOVA analysis
