A. Effect of introduction of anti-CTGF siRNA, anti-CCND1 siRNA, has-miR-26b mimics and control on the mRNA expression level of CTGF in hPASMCs (p<0.01); B. lower panel: Effect of introduction of anti-CTGF siRNA, anti-CCND1 siRNA, has-miR-26b mimics and control on the protein expression level of CTGF in hPASMCs, as determined by western blot; upper panel: densitometric analysis of the western blot results underneath (p<0.01); C. Effect of introduction of anti-CTGF siRNA, anti-CCND1 siRNA, has-miR-26b mimics and control on the mRNA expression level of CCND1 in hPASMCs (p<0.01); D. lower panel: Effect of introduction of anti-CTGF siRNA, anti-CCND1 siRNA, has-miR-26b mimics and control on the protein expression level of CCND1 in hPASMCs, as determined by western blot; upper panel: densitometric analysis of the western blot results underneath (p<0.01). All experiments were repeated three times (N value=3).
