lncRNA EGFEM1P Drives the Progression of Papillary Thyroid Cancer by Regulating miR-6867-5p/CHI3L1 Axis.
Long noncoding RNA (lncRNA), a subgroup of noncoding RNA with > 200 nt, plays critical roles in cancer progression. Here, we aimed to explore the detailed biological function of lncRNA EGFEM1P during papillary thyroid cancer (PTC) progression. RT-qPCR and Western blot were used to analyze the expression of lncRNA EGFEM1P, miR-6867-5p, and CHI3L1. CCK8, colony formation, and Transwell migration assays were undertaken to assess PTC cell proliferation and migration. A xenograft tumor mouse model was also used to establish tumor growth in vivo. Luciferase reporter and anti-AGO2 RNA immunoprecipitation (RIP) assays were used to clarify the interplay between miR-6867-5p and lncRNA EGFEM1P or CHI3L1. We found lncRNA EGFEM1P and CHI3L1 to be highly expressed in PTC tissues and cells, while miR-6867-5p expression decreases. Functionally, lncRNA EGFEM1P silence delays PTC cell proliferation and migration, and impairs tumorigenesis in vivo. LncRNA EGFEM1P targets miR-6867-5p, and CHI3L1 is a target gene of miR-6867-5p. LncRNA EGFEM1P silence decreases the pro-proliferation and pro-migration caused by the miR-6867-5p inhibitor in PTC cells, and CHI3L1 silence abrogates the pro-tumorigenic action resulting from the miR-6867-5p inhibitor in PTC cells. Our data showed that lncRNA EGFEM1P targeting of the miR-6867-5p/CHI3L1 axis drives PTC progression, suggesting lncRNA EGFEM1P as a therapeutically target for PTC.
期刊介绍:
Critical ReviewsTM in Eukaryotic Gene Expression presents timely concepts and experimental approaches that are contributing to rapid advances in our mechanistic understanding of gene regulation, organization, and structure within the contexts of biological control and the diagnosis/treatment of disease. The journal provides in-depth critical reviews, on well-defined topics of immediate interest, written by recognized specialists in the field. Extensive literature citations provide a comprehensive information resource.
Reviews are developed from an historical perspective and suggest directions that can be anticipated. Strengths as well as limitations of methodologies and experimental strategies are considered.
