ZUSAMMENFASSUNG

This study was to investigate the roles of lncRNA associated competitive endogenous RNAs (ceRNAs) network in the endometrial cancer (EC). StarbaseV2.0 online software was used to predict the most probable lncRNAs which contain miR-205-5p binding site and are competent to interact with miR-205-5p. Then, lncRNAs which had decreased expression in EC compared with normal endometrium and conformed to the polyadenylated characteristics of lncRNAs were selected and then lncRNAs associated with miR-205-5p-PTEN network were identified. Two novel genes RP11-395G23.3 and LA16c-313D11.11 associated with endometrial cancer were identified and proved to be non-coding RNAs. They were more effective ceRNAs associated with the miR-205-5p-PTEN network. Our results suggest that lncRNAs harbor MREs (miRNA response elements) and play important roles in the post-transcriptional regulation in EC.
