Abstract

This study was intended to analyze effects of lncRNA CRNDE on cervical cancer cell growth and metastasis. Fifty pairs of cervical cancer tissues and corresponding adjacent tissues were collected. Expressions of long non-coding RNAs (lncRNAs) in tissue samples were detected by microarray analysis. Expression levels of CRNDE in cervical cancer cells and normal cells were detected by qRT-PCR. Cell-counting kit-8 (CCK-8) assay and clone formation assay were utilized to evaluate cell growth. Wound healing assay and Transwell assay were conducted to detect the migratory and invasive capability of cervical cancer cells. The expressions of CRNDE in cervical cancer tissues and cells were higher than those in normal tissues and cells. CCK-8 assay and clone formation assay showed that the knockdown of CRNDE could inhibit the cell proliferation of HeLa and C-33A cells. Wound healing assay indicated that the downregulation of CRNDE expression could suppress the cell migration. The result of a Transwell assay demonstrated that the number of invasion cells reduced in the CRNDE-si group in comparison with the Mock group. LncRNA CRNDE could promote the cell growth and stimulate the metastasis of cervical cancer cells.
