Abstract: Objective: To study the effect of Angiotensin Ⅱ inhibitors,which is angiotensin converting enzyme inhibitor(ACEI)captopril and Ang Ⅱ 1 receptor inhibitor(ARB)valsartan on Ang Ⅱ-induced cervical cancer cell line HeLa AT1R,MMP2,MMP9 protein and gene expression. Methods:Treating cervical cancer HeLa cells alone with Ang Ⅱ,or combined ACEI or ARB. The MTT cell proliferation was detected by immunofluorescence staining method to detect AT1R,MMP2,MMP9 protein levels,Real-Time RT-PCR method of detection AT1R,MMP2,MMP9 gene relative expression. Results:MTT results showed that Ang Ⅱ had no significant role in promoting cell proliferation,but the ACEI and ARB could inhibit the effect of Ang Ⅱ cervical cancer HeLa cells;immunocytochemistry and Real-Time RT-PCR results showed Ang Ⅱ could significantly increase protein and gene expression of AT1R and MMP2 and MMP9,while ACEI and ARB could inhibit the role of Ang Ⅱ. Conclusions:Ang Ⅱcould promote cervical cancer HeLa cells AT1R,MMP2,MMP9 protein and gene expression,which expression could be Ang Ⅱ inhibitors captopril and valsartan inhibited,Ang Ⅱ inhibitors may be a kind of new control of cervical cancer metastasis and prolong survival in patients with cervical cancer drug.
