长链非编码RNA CCAT1对子宫内膜癌细胞迁移侵袭及上皮-间质转化的影响
Effect of long non-coding RNA CCAT1 on metastasis, invasion and epithelial-mesenchymal transition of endometrial carcinoma cell
摘要
Abstract
Objective To investigate the effect of CCAT1 on migration,invasion and epithelial-mesenchymal transition (EMT) in endometrial carcinoma (EC) cell.Methods Using quantitative PCR assay,level of CCAT1 was detected in EC tissues to find its association with the initiation and malignancy degree of EC.Wound heal assay and transwell invasion assay were performed to study the effect of CCAT1 on migration and invasion ability of EC cell,while qPCR and western blot assay were utilized to detect the levels of related genes.Results In EC tissues,level of CCAT1 was significantly upregulated (P ＜ 0.001) and was positively associated with the malignancy degree of EC.After CCAT1 knockout,shorter migration distance was found,fewer cell passed through the chambers,levels of metastasis-related genes (MMP2 and MMP9) and mesenchymal markers (Snail,Zeb1 and Twist1) were up-regulated,and epithelial markers (E-cadherin and ZO-1) were down-regulated.Conclusion CCAT1 was up-regulated in EC tissue and its expression level was positively associated with the malignancy degree of EC.CCAT1 knockdown inhibited the metastasis,invasion and epithelial-mesenchymal transition of EC cell.关键词
