Fig. 1From: RNA interference targeting carbohydrate sulfotransferase 3 diminishes macrophage accumulation, inhibits MMP-9 expression and promotes lung recovery in murine pulmonary emphysemaMorphometric assessment after porcine pancreas elastase (PPE) administration. a Hematoxylin-eosin (HE) staining of lung tissue 21 days after PPE administration. PPE induced the development of airspace enlargement with destruction of the alveolar walls (Control siRNA). CHST3 siRNA attenuated emphysematous change (CHST3 siRNA). Scale bar 200 μm. b Semiquantative analysis of lung tissue using the mean linear intercept (MLI). n = 5. *p < 0.01 versus sham group. † p < 0.01 versus control siRNA groupBack to article page
