| الوصف: | AIM: To evaluate the effect of miRNA-451 on rhesus macaque choroid-retinal endothelial (RF/6A) cell function and proteome profile. METHODS: The RF/6A cells were transfected with miRNA-451 mimic and inhibitor. The role of miRNA-451 on proliferation ability was evaluated by CCK-8 assay. Furthermore, iTRAQ quantitative proteomic analysis was applied to comprehensively illuminate the change of cellular proteins and biological function between different groups. RESULTS: In miRNA-451 overexpression group, cell proliferation of RF/6A decreased both at 24h and 48h; while in miRNA-451 inhibition group, on the contrary, RF/6A cell proliferation was increased at 48h. Based on iTRAQ quantitative proteomic analysis, 23 differentially expressed proteins (DEPs) were detected in the comparison of miRNA-451 mimic and mimic control-transfected RF/6A cells, and 30 DEPs were identified in the comparison of RF/6A cells transfected with miRNA-451 inhibitor and inhibitor control. DEPs such as GORASP2, KRT1, SLC7A2, RIC8A, DDX42, CAP1, PCBP2 might be closely related to the inhibitory effect of miRNA-451 on RF/6A cell proliferation, while PCYT1A, MGAT1, TUBB, MCU, SIL1, BID, MSH6 might account for the positive effect of miRNA-451 inhibitor on RF/6A cell growth. PTPN1, as the only protein exhibiting an opposite trend between miRNA-451 mimic and inhibitor-transfected cells, was most likely accountable for the inhibition of miRNA-451 mimic on RF/6A cell growth, and the promotion of miRNA-451 inhibitor on RF/6A cell proliferation. CONCLUSION: miRNA-451 overexpression can suppress the growth of RF/6A cells while knockdown of miRNA-451 can promote RF/6A cell viability. Among all DEPs, increased PTPN1 is most likely to account for the negative regulation of miRNA-451 on RF/6A proliferation. miRNA-451 can be a protective factor for neovascular disease of fundus via regulating choroid retinal endothelial cell function. |
