Abstract:
AIM:To investigate the effect of microRNA-152-3p(miR-152-3p)targeting insulin-like growth factor 1(IGF1)gene on high glucose-induced retinal pigment epithelial ARPE-19 cell activity and apoptosis, and to explore its role mechanism.
METHODS: High glucose was induced into ARPE-19 cells and transfected with miR-152-3p mimics. MTT assay was used to detect cell proliferation activity. Flow cytometry was used to detect apoptosis. Fluorescence quantitative PCR(RT-PCR)was used to detect cells. The expression levels of IGF1 and VEGF in the cells were detected by Western blot and the binding relationship between IGF1 and miR-152-3p was detected by the dual luciferase reporter gene.
RESULTS:High glucose can decrease the activity of ARPE-19 cells, increase the apoptosis rate, inhibit the expression of miR-152-3p and increase the expression of IGF1 and VEGF. Over expression of miR-152-3p can up-regulate high glucose-induced cells. Increased activity and increased apoptosis inhibited the expression of IGF1 and VEGF. The dual luciferase reporter gene assay verified that IGF1 is the target gene of miR-152-3p.
CONCLUSION: miR-152-3p can inhibit the inhibition of high glucose-induced ARPE-19 cell activity and increase apoptosis by targeting IGF1 gene.
