Abstract

Cervical cancer is one of the most common malignant carcinomas in the female reproductive system. Long non-coding RNAs (lncRNAs) have been verified to participate in the tumorigenesis of cervical cancer. In present study, we investigate the role of lncRNA XLOC_008466 in the occurrence and progression of cervical cancer. Results showed that XLOC_008466 expression was up-regulated in cervical cancer tissue and cells compared to normal controls. In vitro functional experiments, CCK-8 assay and colony formation assay showed that XLOC_008466 knockdown suppressed the proliferation of cervical cancer cells. Flow cytometry and transwell assay showed that XLOC_008466 knockdown induced G0/G1 phase arrest and aggravated the apoptosis. In vivo, XLOC_008466 knockdown inhibited the tumor growth. Bioinformatics analysis revealed that XLOC_008466 sponged miR-216b with the complementary binding sites at 3'-UTR. Overall, our study reveals the tumor promoting role of XLOC_008466 in cervical cancer carcinogenesis, providing a novel molecular mechanism and therapeutic target for cervical cancer.

Keywords: Cervical cancer; Long non-coding RNA; XLOC_008466; miR-216b.
