Background::Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. It has been demonstrated that microRNA-145 (miR-145) is correlated with the progression of various cancers by regulating the expression of multiple target genes, especially a number of genes that regulate angiogenesis and proliferation. However, the underlying mechanisms of miR-145 in tumor angiogenesis of UM are still not well illustrated. Thus, we aimed to explore the potential target genes or pathways regulated by miR-145 in UM and the effect of miR-145 on invasion and angiogenesis.Methods::Totally, 24 choroid samples were collected in our study, including 12 UM samples and 12 normal uveal tissues. The expression of neuroblastoma RAS viral oncogene homolog (N-RAS), phosphorylated protein kinase B (p-AKT), and vascular endothelial growth factor (VEGF) in UM tissues and normal uveal tissues was analyzed using Western blotting analysis. Lentivirus expression system was used to construct MUM-2B and OCM-1 cell lines wit
