Silencing lncRNAs PVT1 Upregulates miR-145 and Confers Inhibitory Effects on Viability, Invasion, and Migration in EC.

ABSTRACT: Long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) is correlated to various malignant tumors. Consequently, we explored effects of lncRNA PVT1 on esophageal carcinoma (EC) targeting microRNA-145 (miR-145). EC tissues, adjacent normal tissues, and EC-related cell lines were collected and cultured. Expression of lncRNA PVT1, miR-145, fascin-1 (FSCN1), and related genes with intervening expression of PVT1 and miR-145 was determined. Bioinformatic website, dual-luciferase reporter assay, and RNA immunoprecipitation (RIP) were carried to verify target relationship among lncRNA PVT1, FSCN1, and miR-145. Scratch test, Transwell assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and flow cytometry were performed for detection of migration, invasi
