Objective:Toinvestigate the influence of MMP7 antisense oligodeoxynucleotide(ASODN)on adhesion and invasion ofhuman lung adenocarcinoma cell line A549.Methods:Phosphorothioate MMP7 ASODN was transfected to A549 cells mediated by liposome. The expression of MMP7 was examined by RT-PCR.The adhesive and invasive ability were examined by plate adhesion model and Boyden Chamber transwell assay.Results:After MMP7 ASODN was transfected
the relative optical density(ROD)of electrophoresis strip was decreased obviously(P<0.01).Compared with A549 group and liposome group
the cells adhering to plate and permeating septum of Boyden chamber were decreased markedly(P<0.01).Conclusion:The MMP7 ASODN could effectively inhibit the expression of MMP7 and reduce the adhesive and invasive ability of A549.
