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).
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.
