Abstract:

AIM: To evaluate the correlation between miRNA-375 and cell proliferation and apoptosis in glioma cancer cell.
METHODS: Collecting 30 cases of glioma cancer patients and 30 cases of cerebral infarction patients. The miRNA-375 and CTGF protein expressions were evaluated by ISH and IHC methods. In the cell experiment, the U87 cells were divided into 3 groups: NC group (the cells were treated with normal method); BL group (the cells were transfected with empty vector) and miRNA group (the cells were transfected with miRNA-375). The U87 cell proliferation and apoptosis rates and cell cycle of the different groups were measured by MTT and flow cytometry. The relative proteins (CTGF, EGFR, AKT, Erk and P21) expressions were measured by WB assay.
RESULTS: The miRNA-375 and CTGF expressions of glioma cancer tissues were significantly different compared with those of no-cancer tissues (p < 0.05, respectively).

In the cell experiments, the cell proliferation of miRNA group was significantly decreased compared with that of NC group (p < 0.05); the cell apoptosis and G1 phase rate of miRNA group was significantly decreased compared with NC group (p < 0.05, respectively). Depending on the WB assay, the CTGF, EGFR, AKT, Erk and P21 proteins expressions of miRNA group were significantly different compared with proteins expressions of NC group (p < 0.05, respectively).
CONCLUSION: miRNA-375 over-expression suppresses glioma cancer cells development via CTGF-EGFR pathway (Fig. 3, Ref. 30).
