Abstract

MicroRNAs (miRNAs/miRs) are short non-coding RNAs (between 20 and 22 nucleotides) that regulate gene expression by binding to the 3'‑untranslated region of target mRNA, and preventing protein translation or inducing mRNA destabilization. miRNAs are predicted to target ~60% of all mRNAs, therefore providing a marked degree of regulation of a number of cellular processes. In the present study, the expression of miR‑548c‑3p was determined by reverse transcription‑quantitative polymerase chain reaction analysis and demonstrated to be markedly downregulated in clinical malignant glioma tissues and the glioma T98G cell line compared with normal human brain tissue. Transfection of miR‑548c‑3p inhibited cell proliferation by inducing G1 cell cycle arrest and also inhibited the migration of the T98G cells in vitro. Furthermore, a bioinformatic algorithm and a luciferase reporter assay identified proto‑oncogene c-Myb (c-Myb) as a potential direct target of miR‑548c‑3p. Further experiments demonstrated that the inhibition of c-Myb by miR-548c-3p partially mediated the antitumor effect of miR‑548c‑3p. The results of the present study provide the novel insight that miR-548c-3p inhibits glioma tumorigenesis by targeting c‑Myb. Therefore, miR-548c-3p may contribute to the development of improved glioma treatment.
