MicroRNAs (miRNAs) are short non-coding RNAs, which negatively regulate gene expression. Post‑transcriptional regulation by miRNAs is important for organism development. In addition, endothelial cells are key regulators of angiogenesis. By using the 3-(4,5-dimethylthiazol-2-yl)‑2,5‑diphenyltetrazolium bromide (MTT), migration and gelatin sponge-chorioallantoic membrane assays, it was demonstrated that when miR-137 was overexpressed, cell viability and migration decreased. In addition, it was observed that blocking endogenous miR-137 increased cell viability and migration. Bioinformatics analysis indicated that the 3'‑untranslated region (3'UTR) of the ephrin type-A receptor 7 (EPHA7) has a putative binding site for miR-137. miR-137 is able to directly bind to the EPHA7 3'UTR and negatively regulate the expression of EPHA7. miR-137 is also able to decrease the growth and migration of human umbilical vein endothelial cells (HUVECs). The identification of the function of miR-137 and its target gene EPHA7 in HUVECs may provide novel insights into the mechanisms of angiogenesis.
