Increasing evidence has demonstrated that microRNAs (miRNAs) have a crucial role in the initiation and progression of tumors. The present study aimed to investigate the expression and the role of miRNA-454-3p in human cervical cancer. Human cervical cancer cells were transfected with miRNA-454-3p mimics or negative control miRNA. MTT, Transwell and wound healing assays were performed to investigate the effects of miRNA-454-3p overexpression on cell proliferation, invasion and migration, respectively. The results indicated that miRNA-454-3p was down-regulated in human cervical cancer cell lines, while its ectopic overexpression significantly inhibited their proliferation, migration and invasion. Furthermore, a luciferase reporter assay confirmed that c-met was a novel target of miRNA-454-3p in HeLa cells. In conclusion, the results of the present study suggested that miRNA-454-3p exhibits significant tumor-suppressive effects in cervical cancer by targeting c-met, and may be a potential means of treating cervical cancer.
越来越多的证据表明,微小RNA(miRNA)在肿瘤的发生和发展中起关键作用。本研究旨在探讨miRNA-454-3p在人宫颈癌中的表达及其作用。用miRNA-454-3p模拟物或阴性对照miRNA转染人宫颈癌细胞。分别进行MTT、Transwell和伤口愈合试验,以研究miRNA-454-3p过表达对细胞增殖、侵袭和迁移的影响。结果表明,miRNA-454-3p在人宫颈癌细胞系中表达下调,而异位过表达则显著抑制其增殖、迁移和侵袭。此外,荧光素酶报告基因检测证实c-met是HeLa细胞中miRNA-454-3p的一个新靶点。总之,本研究结果表明,miRNA-454-3p通过靶向c-met在宫颈癌中表现出显著的肿瘤抑制作用,可能是治疗宫颈癌的一种潜在手段。
