MicroRNAs (miRNAs) are small non-coding RNAs that regulate diverse biological processes. We cloned novel small RNA from human mesenchymal stem cells (hMSCs) and termed microRNA-5787 (hsa-miR-5787) that met the criteria for a miRNA. The level of miR-5787 was elevated in senescent fibroblasts. Based on the target prediction algorithm and results that were obtained, we find that eukaryotic translation initiation factor 5 (eIF5) is a target of miR-5787. Similar to the over-expression of miR-5787, we showed that repression of eIF5 in fibroblasts negatively affected cell growth. Therefore, we propose that the miR-5787 represses cell growth, in part, by targeting eIF5.
► In the current study, we discovered the novel hsa-miR-5787.
► It was up-regulated in senescent fibroblasts.
► We selected the eIF5 as target gene according to the target prediction algorithm.
► Finally, we showed that the hsa-miR-5787 inhibited the cellular growth by targeting eIF5.
