  • Abstract:Glioma stem cells (GSCs) contribute to the malignant biological behavior of these tumors and have also been shown to be resistant to radiation and chemotherapy. Recently, a variety of microRNAs (miRNAs) has been found to present altered expression and to play an important oncogenic role or tumor-suppressive function in cancer stem cells (CSCs). microRNA-608 (miR-608) is one of the newly discovered microRNAs, and its biological functions remain unclear. Human macrophage migration inhibitory factor (MIF) is a well known oncogene associated with tumor recurrence and the poor prognosis of gliomas. In the present study, we found that miR-608 negatively regulated the gene expression of MIF at the post-transcriptional level and plays a tumor-suppressive role by targeting MIF in GSCs. We found that miR-608 expression was significantly downregulated and the expression levels of the MIF gene and protein showed an increase in the GSCs. miR-608 overexpression significantly attenuated the proliferation, migration and invasion, and induced the apoptosis of GSCs. The dual-luciferase reporter system revealed that the 3＇UTR of MIF is a direct target of miR-608, and miR-608 negatively regulates the gene expression of MIF at the post-transcriptional level by targeting its 3＇UTR. Furthermore, we demonstrated that miR-608 overexpression inhibited the malignant behavior of GSCs by downregulating MIF. Western blot results showed that the inhibition of MIF resulted in the inactivation of the PI3K/AKT and JNK pathways. These results demonstrate that miR-608 acts as a potential tumor suppressor and provide insight into new therapeutic targets for malignant glioma.
