Reference title
LncRNA NCK1-AS1 promotes proliferation and induces cell cycle progression by crosstalk NCK1-AS1/miR-6857/CDK1 pathway.
Experimental verification
Microarray,qRT-PCR,Western blot,Luciferase reporter assay,in vitro knockdown
Functional description
Functionally,we screened the CC-associated lncRNA NCK1-AS1 as a new candidate lncRNA and regulator which promotes development and progression in CC. qRT-PCR and RNA in situ hybridization (RISH) results showed that NCK1-AS1 was significantly up-regulated in 77.4% of the CC tissue group compared with the normal group.Interestingly,we demonstrated that transcription factor SP1 directly binds to the promoter to activate NCK1-AS1 expression in SiHa cells.In vitro and in vivo assays of silencing NCK1-AS1 significantly inhibited cell proliferation and invasion, with induction of cell arrest in S phase of the cell cycle.Furthermore,Human Transcriptome Array 2.0 analysis after NCK1-AS1 silencing highlighted alterations in cell proliferation and cell cycle pathways.NCK1-AS1 functioned as a molecular sponge for miR-6857, antagonizing its ability to repress CDK1/6 protein translation.
