Effect of SIS3 on Extracellular Matrix Remodeling and Repair in a Lipopolysaccharide-Induced ARDS Rat Model

<div>SIS3 inhibited the protein expression of RAGE, TGF-<i>β</i>1, MMP2, and MMP9 proteins in lung homogenates acquired from ARDS rats. The expression levels of RAGE, TGF-<i>β</i>1, MMP2, and MMP9 proteins in lung tissue homogenates, sera, and BALF of ARDS rats and were determined using western blotting analysis at 24 h after LPS intervention. The results of western blotting showed that SIS3 inhibited LPS-induced (a) RAGE, (b) TGF-<i>β</i>1, (c) MMP2, and (d) and MMP9 protein expression in the lung homogenates.
