Despite the increasing incidence of papillary thyroid cancer in the past decade, the molecular mechanism underlying its progression remains unknown. Several studies have reported down‐regulation of miR‐451a or circular miR‐451a in papillary thyroid cancer cell lines or patients. However, the underlying molecular mechanism remains unknown. In this study, we found that overexpression of miR‐451a could inhibit proliferation, epithelial‐mesenchymal transition and induce apoptosis in papillary thyroid cancer cells. Proteasome subunit beta type‐8 was predicted to be a direct target of miR‐451a and was validated with a luciferase reporter assay. Further functional assays showed that miR‐451a could inhibit thyroid cancer progression by targeting proteasome subunit beta type‐8.
