ABSTRACT
Accumulating evidence has indicated the vital roles of long noncoding RNA (lncRNA) in the epithelial ovarian cancer (EOC). However, the function of lncRNA HAS2-AS1 in EOC is still unclear. This study aims to investigate the expression and role of HAS2-AS1 in EOC. In the cells and tissue of EOC, HAS2-AS1 expression was markedly up-regulated. Besides, the overexpression of HAS2-AS1 indicated the poor clinical outcome of EOC patients. Transcription factor CREB1 could bind with the promoter of HAS2-AS1 and activate its transcriptional expression. Functionally, HAS2-AS1 knockdown suppressed the proliferation, invasion and tumor growth of EOC cells in vitro and in vivo. Mechanical investigation found that HAS2-AS1 could relive the RUNX2 protein expression via sponging the miR-466, acting as miRNA sponge. In conclusion, this finding suggests the CREB1/HAS2-AS1/miR-466/RUNX2 axis in the in the EOC tumorigenesis, providing the novel insight for the molecular mechanism of EOC.
