Long noncoding RNAs (lncRNAs) have been reported to play vital roles in various human cancers. The aim of this study was to explore the critical role of lncRNA HOXA11-AS in uveal melanoma (UM) progression. Briefly, we found that HOXA11-AS is overexpressed in UM tissues and cells; HOXA11-AS could regulate UM cell growth, invasion, and apoptosis. Mechanistically, RNA immunoprecipitation demonstrated that HOXA11-AS could simultaneously interact with enhancer of zeste homolog 2 (EZH2) to suppress its target p21 protein expression. In addition, we demonstrated that HOXA11-AS functioned as a molecular sponge for miR-124, and overexpression of miR-124 attenuated the proliferation and invasion-promoting effect of HOXA11-AS. Collectively, our findings reveal an oncogenic role for HOXA11-AS in UM tumorigenesis.
