Abstract

BACKGROUND

The aim of this study was to investigate the potential function of miR-126 in neural stem cells (NSCs).

MATERIAL AND METHODS

Expression level of miR-126 was detected by quantitative real-time PCR (qRT-PCR). MiR-126 overexpression was established by transfecting miR-126 mimics into human NSC lines (HB1.F3 and HB1.A4 cells). Its effects on cell proliferation were studied using cell-counting kit-8 (CCK8) assay, colony formation assays. Flow cytometry was performed to evaluate the effect of miR-126 on cell survival.

RESULTS

CCK8 assay and colony formation assay showed that overexpression of miR-126 promoted cell proliferation and increased colony numbers in HB1.F3 and HB1.A4 cells. The flow cytometry confirmed the results that miR-126 inhibited cell apoptosis.

CONCLUSIONS

MiR-126 promoted the proliferation and survival of NSCs.

摘要

背景

本研究旨在探讨miR-126在神经干细胞（NSCs）中的潜在功能。

材料与方法

采用定量实时聚合酶链反应（qRT-PCR）检测miR-126的表达水平。通过将miR-126模拟物转染到人神经干细胞系（HB1.F3和HB1.A4细胞）中来实现miR-126的过表达。使用细胞计数试剂盒-8（CCK8）检测法、集落形成试验研究其对细胞增殖的影响。进行流式细胞术以评估miR-126对细胞存活的影响。

结果

CCK8检测法和集落形成试验表明，miR-126的过表达促进了HB1.F3和HB1.A4细胞的增殖并增加了集落数量。流式细胞术证实了miR-126抑制细胞凋亡的结果。

结论

miR-126促进了神经干细胞的增殖和存活。
