This study aims to determine the function and mechanism of circPRMT5 in the regulation of PTC development.Methods: PTC tissues and cell lines were used to determine circPRMT5 expression via quantitative real-time polymerase chain reaction. Small interfering RNA (siRNA) was utilized to knock down circPRMT5. Proliferation was analyzed through CCK8 and colony formation assays. Transwell assay was performed to determine cell migration and invasion. Luciferase assay and RIP assay were carried out to analyze the interaction between circPRMT5 and miR-30c.Results: CircPRMT5 expression was upregulated in PTC tissues and cell lines. And circPRMT5 level was positively linked with advanced stage and lymph node metastasis. CircPRMT5 knockdown inhibited proliferation, migration and invasion while inducing apoptosis. CircPRMT5 worked as a competing endogenous RNA for miR-30c. By inhibiting miR-30c, circPRMT5 promoted the expression of E2F3.Conclusion: Our findings demonstrate that circPRMT5 acts as an oncogenic circRNA to promote PTC progression via regulating miR-30c/E2F3 axis.Keywords: circRNA, papillary thyroid cancer, circPRMT5, miR-30c, E2F3https://www.dovepress.com/circular-rna-circprmt5-accelerates-proliferation-and-invasion-of-papil-peer-reviewed-article-CMARcircrnapapillary thyroid cancercircprmt5mir-30ce2f3 |
