Tomoregulin-1 improves cardiac pathological changes after pressure overload. Tomoregulin-1 improves cardiac pathological changes after pressure overload. H&E staining patterns of the whole-heart cross-sections from mice at 4 weeks after sham and TAC operation (A). Magnification of H&E-stained sections of the left ventricle (LV), showing disparate pathological changes (B). Magnification of Masson-trichrome-stained sections of LV; myocytes, stained red; collagenous tissue, stained green (C). The expression of Col3α1 was detected by real-time PCR, and the quantitative analysis of the expression of Col3α1 made using GAPDH for normalization (D; n=3 independent experiments, *P<0.05 versus NTG mice).
