Objective:To investigate the potential biological effects of long non-coding RNA Dleu2 on the characteristics of cervical
cancer cells, including items of proliferation, migration and invasion.Methods:High throughput microarray screening of LncRNA
was performed with 10 different cervical cancer tissues as samples and corresponding para-carcinoma tissues as controls, LncRNAs with
significantly different expression levels were selected and among which, the microarray results of LncRNA Dleu2 was further verified by
q-PCR method, then the overexpression of Dleu2 in Hela and Caski, were performed to investigate its potential functions on the proliferation,
migration and invasion of these two cervical cancer cell lines, which characteristic items were quantified separately by CCK8,
clone-forming unit assay, wound healing assay and tumor invasion assay methods.Results:Both the results of Microarray and q-PCR
demonstrated that the expression level of Dleu2 was significantly much lower in cervical cancer tissues and cell lines as compared with
corresponding normal controls. The results of CCK8 assay and colony-forming unit assay showed that Dleu2 overexpression could significantly
decrease cervical cancer cell proliferation. Wound Healing assay results indicated that Dleu2 overexpression could obviously suppress
cervical cancer cell proliferation and migration. Tumour invasion assay results demonstrated that Dleu2 could significantly suppress
cervical cancer cell invasion.Conclusion:The expression levels of Dleu2 are relatively much low in cervical cancer tissues and cell lines.
The overexpression of Dleu2 can significantly inhibit the ability of proliferation,migration and invasion of Hela and Caski cells. |
