LINC00319 promotes migration, invasion and epithelial-mesenchymal transition process in cervical cancer by regulating miR-3127-5p/RPP25 axis.

Cervical cancer is among the most prevalent malignancies for women. An increasing number of evidences have been proved that long non-coding RNAs (lncRNAs) play significant role in the initiation and progression of cervical cancer. However, the function of long intergenic non-protein coding RNA 319 (LINC00319) in cervical cancer still remains vague. In this study, our purpose was to investigate the effects of LINC00319 on cell migration, invasion and epithelial-mesenchymal transition (EMT) process in cervical cancer. It confirmed that LINC00319 was highly expressed in tissues and cell lines in cervical cancer. Further, overexpression of LINC00319 accelerates cell migration, invasion and EMT in cervical cancer. Moreover, LINC00319 could bind with miR-3127-5p and negatively regulated its expression. Besides, RPP25 was targeted by miR-3127-5p, and its expression was negatively/positively regulated by miR-3127-5p/LINC00319. Additionally, miR-3127-5p mimics or RPP25 insufficiency could offset the encouraging effects of LINC00319 overexpression on migration, invasion and EMT process in cervical cancer. Generally speaking, LINC00319 promotes migration, invasion and EMT process in cervical cancer by regulating miR-3127-5p/RPP25 axis, which may be conductive to cervical cancer treatment.
