Abstract: Objective To investigate the effects of interfering with the expression of the lncRNA NCK1-AS1 on the growth and invasion of the thyroid cancer cell line CAL-62. Methods lncRNA NCK1-AS1 expression in CAL-62 cells was silenced by transfecting the corresponding shRNA.The expression level of lncRNA NCK1-AS1 was detected by RT-PCR.Cell proliferation was assessed by EdU staining,and apoptosis was analyzed by flow cytometry.RT-PCR was used to detect the mRNA expression levels of proliferating cell nuclear antigen(PCNA),p21,and Survivin.Cell invasion was assessed using the Transwell assay,and the number of microtubule-like structures was measured via a microtubule formation assay.Western blot analysis was performed to detect the expression levels of vascular endothelial growth factor(VEGF),E-cadherin,and N-cadherin. Results Compared with the control group,the lncRNA NCK1-AS1 interference group exhibited reduced cell proliferation,increased apoptosis,downregulated PCNA and Survivin mRNA levels,upregulated P21 mRNA levels,decreased number of invading cells and microtubule-like structures,downregulated VEGF and N-cadherin protein expression,and upregulated E-cadherin expression.These differences were statistically significant(P<0.05). Conclusion Silencing the expression of lncRNA NCK1-AS1 inhibits the growth and invasion of CAL-62 thyroid cancer cells.
