ABSTRACT
Hemangioma (HA), which is characterized by aberrant endothelial cell proliferation in blood vessels, is a common tumor during infancy. MicroRNAs (miRNAs/miRs) collectively participate in the development of HA; however, the potential roles of miR-195-5p in HA are not completely understood. The aim of the present study was to investigate the roles of miR-195-5p in HA. In the present study, miR-195-5p was found to be downregulated in HA cells, such as the XPTS-1 human infantile hemangioma-derived endothelial cell line and the EOMA hemangioendothelioma cell line. Overexpression of miR-195-5p was shown to suppress HA cell viability, colony formation and proliferation, and induced HA cell apoptosis. Furthermore, miR-195-5p downregulated Bcl-2 expression and upregulated Bax and Bcl-2 expression levels. V-ski sarcoma viral oncogene homolog (SKI) was ident ified as a target of miR-195-5p. Co-transfection of miR-195-5p mimics and SKI 3'-untranslated region wild-type decreased HA cell luciferase activity. SKI overexpression alleviated the miR-195-5p-induced decrease in HA cell proliferation and increased HA cell apoptosis. In addition, the regulatory role of miR-195-5p on the expression of Bcl-2, Bax and poly(ADP-ribose) polymerase was reversed by SKI. Collectively, the results of the present study demonstrated that miR-195-5p suppressed HA progression and its effects were mediated via SKI. Therefore, the miR-195-5p/SKI axis may represent a novel therapeutic target for HA.
