Abstract
In order to demonstrate the potential therapeutic effect of two flavonoids, Baicalein and Wogonin, on suppression of pathological myocardial fibrosis in hypertension, we investigated their in vitro effects on collagen expression in primary cultured cardiac fibroblasts isolated from neonatal normotensive (WKY) and hypertensive (SHR) rats. Our results showed that over-expression of collagen mRNA and protein induced in cardiac fibroblasts by angiotensin (AngII) could be attenuated significantly by both flavonoids at an optimal dosage (30 μM; P < 0.01). Results of immunoblots showed that expression of 12-LO level, p-ERK/ERK ratio and MMP-9 in AngII-stimulated SHR cardiac fibroblasts were significantly down-regulated by both flavonoids. Our results show that both Baicalein and Wogonin can suppress collagen deposition in AngII-stimulated SHR and WKY cardiac fibroblasts.
