Characterization of microRNA‐223‐3p as a novel promoter of cell proliferation and invasion in papillary thyroid carcinoma

Abstract

Papillary thyroid carcinoma (PTC), the most common thyroid cancer, has been linked to various molecular alterations. This study focuses on microRNA‐223‐3p, whose upregulated expression in PTC tissues appears to enhance tumor growth and cellular dysfunctions. Our findings demonstrate that microRNA‐223‐3p significantly promotes cell proliferation, invasion, and migration and induces epithelial‐mesenchymal transition (EMT). Additionally, neurofibromatosis type 2 (NF2) is identified as a direct target, suggesting that microRNA‐223‐3p could be crucial in PTC pathogenesis and may offer a target for therapeutic intervention.
