Fig. 4From: Oxymatrine inhibits aldosterone-induced rat cardiac fibroblast proliferation and differentiation by attenuating smad-2,-3 and-4 expression: an in vitro studyInhibitory effect of OMT on ALD-induced hydroxyproline (Hyp) secretion by cardiac fibroblasts. Cardiac fibroblasts were pre-treated with 7.57 × 10−4 mol/L [High] or 3.78 × 10−4 mol/L [Low] OMT or without OMT for 2 h, and then coincubated with ALD (1 × 10−8 mol/L) for 46 h. a Analysis of hydroxyproline content in cell lysis buffer and (b) cell supernatant. Results are means ± SEM of three independent experiments. (*P < 0.05, **P < 0.01 vs. control cells; # P < 0.05, ## P < 0.01 vs. ALD alone, n = 4)Back to article page
