[目的]构建FBXO47基因3'-UTR双荧光素酶报告载体,并验证miR-33b-5p与FBXO47的靶向关系。[方法]采用生物信息学软件预测miR-33b-5p与FBXO47结合位点;利用PCR扩增FBXO47基因3'-UTR序列,将其克隆到GV272载体中,构建FBXO47野生型及突变型双荧光素酶报告质粒;将miR-33b-5p或阴性对照分别与野生型GV272-FBXO47-wt 3'-UTR或突变型GV272-FBXO47-mut 3'-UTR双荧光素酶报告质粒共转染至293T细胞中,双荧光素酶报告系统检测各组荧光素酶活性。[结果]酶切及测序结果表明,野生型GV272-FBXO47-wt 3'-UTR及突变型GV272-FBXO47-mut 3'-UTR双荧光素酶报告载体构建成功;荧光素酶活性结果表明,相较于对照组,miR-33b-5p可使野生型GV272-FBXO47-wt 3'-UTR的荧光素酶活性降低66%左右;而定点突变GV272-FBXO47-mut 3'-UTR的荧光素酶荧光素酶活性没有显著变化。[结论]成功构建了FBXO47基因3'-UTR的荧光素酶报告基因载体,miR-33b-5p与FBXO47存在靶向性。 展开更多

It has been certified that GABPB1-AS1 is aberrantly expressed and plays as a vital role in some kinds of cancers.However,its expression pattern and functions in non-small cell lung cancer(NSCLC)are still largely unknown.This study aims to assess GABPB1-AS1 expression and biological roles in NSCLC.The expression of GABPB1-AS1 was detected in NSCLC specimens and adjacent normal specimens.CCK8 and Transwell assays were performed to evaluate the effects of GABPB1-AS1 on NSCLC cell proliferation,migration and invasion.Bioinformatics tools and luciferase reporter assays were applied to predict and verify GABPB1-AS1’s direct targets.The results revealed that GABPB1-AS1 is sharply reduced in NSCLC specimens and cell lines.CCK8 assays indicated that overexpression of GABPB1-AS1 dramatically reduced NSCLC cell growth,and Transwell assays proved that NSCLC cell migration and invasion were distinctly inhibited by GABPB1-AS1.Exploration of the mechanism uncovered that miRNA-566(miR-566)/F-box protein 47(FBXO47)is directly targeted by GABPB1-AS1 in NSCLC.The study demonstrated that GABPB1-AS1 inhibited NSCLC cell proliferation,migration and invasion by targeting miR-566/FBXO47. 展开更多
