Emerging reports have indicated that long non-coding RNAs (lncRNAs) play pivotal roles in multiple cancers, containing cervical cancer. LncRNA ARAP1 antisense RNA 1 (ARAP1-AS1) was previously identified as a tumor-promoter in bladder cancer. However, the expression profile and possible modulation mechanism of ARAP1-AS1 in cervical cancer need to be further studied. In the current research, ARAP1-AS1 was discovered to exhibit a high level in cervical cancer cells. Besides, the knockdown of ARAP1-AS1 repressed cell proliferative and migratory capacities in cervical cancer, as detected by loss-of-function assays including CCK-8, EdU, colony formation, and transwell assays. Additionally, dual-specificity phosphatase 5 (DUSP5), lowly expressed in cervical cancer cells, was found to be negatively modulated by ARAP1-AS1. In subsequence, mechanism experiments proved that ARAP1-AS1 recruited enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) to regulate DUSP5 expression. Finally, rescue assays certified the oncogenic function of ARAP1-AS1/EZH2/DUSP5 axis in cervical cancer. This research probed the expression level and regulatory mechanism of ARAP1-AS1 underlying cervical cancer, which might shed novel lights into the exploration on cervical cancer treatment.
