摘　　要：目的研究CD147 siRNA转染对恶性黑素瘤细胞株A375中CD147表达及细胞增殖的影响。方法将前期构建的重组质粒pSUPER／CD147 siRNA稳定转染至恶性黑素瘤细胞株A375中,采用半定量RT-PCR法检测转染细胞中CD147 mRNA的表达。采用MTT法检测转染pSUPER／CD147 siRNA对肿瘤细胞增殖的影响。结果转染了pSUPER／CD147 siRNA的恶性黑素瘤细胞株A375中CD147 mRNA 表达水平显著下调,其在转染后24 h、48 h和72 h的增殖水平均显著下降。结论 siRNA转染能有效抑制恶性黑素瘤细胞株A375中CD147的表达,且能抑制肿瘤细胞的增殖能力。Objective To investigate the effects ofsiRNA targeting CD147 gene on the expression of CD147 in melanoma cell line A375, and on proliferation of these cells. Methods Previously prepared recombinant plasmid pSUPER/CD147 siRNA was used. In this study, the recombinant was transfected into the A375 cells. The mRNA expression of CD147 was measured by semi-quantitive RT-PCR, the proliferation of the cells by MTT assay. Results After the transfection with pSUPER/CD147 siRNA1 and pSUPER/CD147 siRNA2, the mRNA expression of CD147 in the A375 cells was significantly down-regulated by 90.81% （ P 〈 0.001 ） and 13.37% （ P 〈 0.05 ） respectively. The proliferation levels of transfected tumor cells at 24, 48 and 72 h after the transfection with pSUPER/CD147 siRNA1 also decreased significantly by 49.42%, 52.60% and 53.33% respectively （ P 〈 0.05, 〈 0.001, 〈 0.001, respectively ）. Conclusion siRNA targeting CD147 gene could effectively inhibit the expression of CD147 in A375 cells, and inhibit the prolif- eration of these cells.
