Downregulation of NEAT1 reverses the radioactive iodine resistance of papillary thyroid carcinoma cell via miR-101-3p/FN1/PI3K-AKT signaling pathway.

ABSTRACT: Considering the resistance of papillary thyroid cancer (PTC) ¹³¹I therapy, this study was designed to find a solution at molecular respect. By probing into lncRNA-NEAT1/miR-101-3p/FN1 axis and PI3K/AKT signaling pathway, this study provided a potential target for PTC therapy. ¹³¹I-resistant cell lines were established by continuous treatment with median-lethal ¹³¹I. Bioinformatic analysis was applied to filtrate possible lncRNA/miRNA/mRNA and related signaling pathway. Luciferase reporter assay was employed in the verification of the targeting relationship between lncRNA and miRNA as well as miRNA and mRNA. MTT assay and flow cytometry assay were performed to observe the impact of NEAT1/miR-101-3p/FN1 on cell viability and apoptosis in radioactivity iodine
