Our results demonstrate that MMP-9 targeted RNAi is able to successfully suppress MMP-9 gene expression and inhibit cell growth and invasion of SGC7901 gastric adenocarcinoma in vitro and in vivo.
Furthermore, knockdown of HMGB1 by shRNA inhibited cell proliferative activities and invasive potential, and downregulated the expression of NF-κB p65, PCNA and MMP-9 in GAC cells (SGC-7901 and AGS).
