Objectiv To explore the mechanism of SOCS3 on the migration and invasion of human lung adenocarcinoma cell line A549. Methods A549 cells that express SOCS3 stably were generated. The migration and invasion abilities of A549 cells were observed by Boyden Chamber assay. The mRNA and protein expressions of MMP-2 and MMP-9 were assessed by semi-quantitive RT-PCR and gelatin zymography respectively. Results Compared with the control group
the migration and invasion abilities of A549 cells with stable SOCS3 expression were significantly lower (P0.05). The mRNA expression and activities of MMP-2 and MMP-9 in A549 cells with stable SOCS3 expression were inhibited significantly (P0.05). Conclusion SOCS3 protein inhibits the migration and invasion abilities of A549 cells probably by down-regulating the expression and activation of MMP-2 and MMP-9.
