摘要: 目的 探讨miR-24对人结肠癌SW620细胞CARMA3的靶向调控作用及对细胞增殖的影响。方法 培养SW620细胞,用生物信息学预测miR-24和CARMA3的靶向匹配关系,并用双荧光素酶报告基因系统鉴定。Lipo3000转染miR-24模拟物后,real-time PCR检测miR-24和CARMA3 mRNA表达;Western blot检测CARMA3蛋白表达;CCK8检测SW620细胞增殖。结果 miR-24和CARMA3匹配良好,miR-24能够结合CARMA3 mRNA 3'UTR,并有效抑制其表达(P<0.05)。miR-24能够负向调控CARMA3表达和SW620细胞增殖(P<0.05)。结论 miR-24通过靶向作用于CARMA3 mRNA 3'UTR能够负向调控CARMA3基因的表达及负向调控SW620细胞的增殖。

Abstract: Objective To identify the role of miR-24 in human colorectal cancer SW620 cell proliferation. Methods SW620 cells were cultured in vitro. The miR-24 was predicted with bioinformatics and identified with dual luciferase report system. Expressions of miR-24 and CARMA3 were determined with Real-time PCR and Western blot after transfection of miR-24. The proliferation of SW620 cells was detected in vitro by CCK8. Results miR-24 can inhibit CARMA3 expression by binding to 3’ UTR of CARMA3 mRNA. miR-24 can negative control the CARMA3 expression. The proliferation of SW620 cells was negative controlled by miR-24. Conclusion The miR-24 may negatively regulate CARMA3 expression by binding to its 3’ UTR in human colorectal cancer SW620 cells and cell proliferation.
