Fig. 6 Expression of Collagen Ⅰ, Collagen Ⅲ, MMP-2 and MMP-9. (A) Expression of Collagen Ⅰ/ Ⅲ mRNA analyzed with RT-PCR. The statistical result of Collagen Ⅰ, Collagen Ⅲ mRNA expression. (B) Expression of Collagen Ⅰ/ Ⅲ detected with Western blot. (C) The statistical result of expression of Collagen Ⅰ, Collagen Ⅲ proteins. (D) Expression of MMP-2 and MMP-9 mRNA analyzed with RT-PCR. The statistical result of MMP-2 and MMP-9 mRNA expression. (E) Expression of MMP-2 and MMP-9 proteins. (F) The statistical result of expression of MMP-2 and MMP-9 proteins. Histograms represented means ± SD of relative quantification from three independent experiments. *p < 0.05 versus control group,#p < 0.05 versus LPS group. †p < 0.05 versus LPS+serelaxin group.&p < 0.05 versus LPS+serelaxin+GW group.
