Effects of miRNA-130a on the proliferation and apoptosis of glioma cell lines

Regulatory ability of micro-ribose nucleic acid-130a (miRNA-130a) in the proliferation and invasive growth of human brain glioma cells and its mechanism were investigated. RT-qPCR was used to analyze expression of miRNA-130a in U-87MG glioma specimens; lipidosome was used to mediate miRNA-130a mimic transfecting glioma cells and the expression of miRNA-130a was detected by using RT-qPCR after transfection; methyl thiazolyl tetrazolium (MTT) assay and flow cytometry (FCM) were adopted to evaluate the changes in biological characteristics of cell growth and proliferation; the migration and invasion abilities of tumor cells were measured through scratch assay and Transwell in vitro cell migration assay. In miRNA-130a mimic-transfected U-87MG cells, RT-qPCR showed that the expression of miRNA-130a was upregulated; MTT assay and FCM revealed that the cell growth was strengthened; scratch assay and Transwell in vitro cell migration assay verified that the migration and invasion abilities of cells were enhanced. In conclusion, the high expression of miRNA-130a can promote growth and invasion, indicating that miRNA-130a can be considered as a candidate target of gene therapy for glioma.
