Univariate Cox regression and least absolute shrinkage and selection operator (LASSO) Cox regression analyses were performed on the DEGs using The Cancer Genome Atlas (TGCA) Program data. MAPK13 was subsequently identified as promoting progression in PTC. The association between MAPK13 expression and clinicopathological features was analyzed using data from public database and the collected cohort. The CCK-8 assay, EdU assay, wound healing assay, transwell assay, flow cytometry, GSEA enrichment analysis, and xenograft model were used to investigate the function of MAPK13 in PTC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Higher expression of MAPK13 was associated with poorer progression-free survival, higher tumor pathologic stage, extrathyroidal extension, lymph node metastasis, multifocal tumors, American Thyroid Association (ATA) stratification system level, and BRAFV600E mutation. Overexpression of MAPK13 significantly promoted cell proliferation, migration, and invasion, and inhibited apoptosis of PTC. Knockdown of MAPK13 significantly inhibited cell proliferation, migration, and invasion, and promoted apoptosis of PTC. Epithelial-mesenchymal transition (EMT) was significantly enriched in GSEA analysis. Higher MAPK13 expression was related to higher N-cadherin and lower E-cadherin expression. Knockdown of MAPK13 significantly prevented tumor growth in vivo.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>MAPK13 promotes the malignant biological behavior of PTC cells and is associated with EMT.
