miR‐214 regulated papillary thyroid carcinoma (PTC) cell metastasis and growth by regulating PSMD10. 33 In addition, miRNA‐361‐5p inhibited PTC progression by targeting ROCK1. However, the roles of miR‐338‐3p in TC progression, especially the relationship with mRNA were still poorly understood. This evidence concerns the gene PSMD10 and differentiated thyroid carcinoma.
