Fig. 7From: RNA interference targeting carbohydrate sulfotransferase 3 diminishes macrophage accumulation, inhibits MMP-9 expression and promotes lung recovery in murine pulmonary emphysemaKinetics of TNF-α and MMP-9 mRNA after PPE administration. Real time quantitative PCR analysis of (a) TNF-α, (b) MMP-9 mRNA in the lung. Total RNA was isolated from lung tissues on days 0, 7, and 21 after PPE administration. (n = 5 per group). *p < 0.05 versus the Sham group. † p < 0.05 versus the Control siRNA groupBack to article page
