MiR-532-5p acts as a tumor suppressor and inhibits glioma cell proliferation by targeting CSF1.

OBJECTIVE: Recent studies have discovered a class of micro-RNAs (miRNAs), which are dysregulated in various tumors and associated with carcinogenesis. In our research, we aim to uncover the molecular functions of miR-532-5p in glioma development. PATIENTS AND METHODS: Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was performed to detect miR-532-5p expression in 48 glioma samples and 4 glioma cell lines. The Pearson's Chi-square test was used to determine the association of miR-532-5p expression with several clinicopathological indexes in glioma patients. Besides, cell proliferation assay, colony formation assay, and Ethynyl deoxyuridine (EdU) incorporation assay were performed to explore in vitro effects of miR-532-5p on glioma cells. Furthermore, the interaction between miR-532-5p and CSF1 in glioma was studied by performing Western blot assay and Dual-Luciferase Reporter Gene Assay. RESULTS: Downregulated miR-532-5p expression was observed in glioma tissues compared with adjacent normal samples. MiR-532-5p expression was associated with the KPS score and tumor grading in glioma patients. Moreover, cell proliferation of glioma was inhibited after overexpression of miR-532-5p in vitro. Furthermore, CSF1 was a target of miR-532-5p in glioma. After overexpression of miR-532-5p, CSF1 was downregulated at mRNA and protein levels in vitro Besides, the expression of CSF1 in glioma tissues was negatively related to that of miR-532-5p. CONCLUSIONS: Malignant phenotypes of glioma cells were remarkably suppressed through the overexpression of miR-532-5p. MiR-532-5p/CSF1 axis was identified as a new therapeutic intervention for the treatment of glioma.
