Cell proliferation was assessed using the CCK\u20108 assay and colony formation assay. Tumor growth was evaluated using nude mouse xenograft models. Cell invasion was evaluated using the transwell assay, while cell migration was assessed with the wound healing assay. Transcriptomic analysis was conducted to examine the molecular mechanism, and real\u2010time quantitative PCR was performed for gene expression validation. The findings revealed that CHI3L1 expression was upregulated in various cancers, mainly in PTC. Both in\u00a0vitro and in\u00a0vivo assays demonstrated that cell proliferation was suppressed when CHI3L1 was knocked down. Transcriptome sequencing indicated that CHI3L1 knockdown was associated with migration\u2010related pathways and the TP53 signaling pathway. Transwell assays showed reduced cell invasion upon CHI3L1 suppression, while wound healing assays demonstrated decreased cell migration. Following CHI3L1 silencing, real\u2010time quantitative PCR verified the overexpression of TP53\u2010related genes. Survival analysis further indicated a correlation between elevated CHI3L1 expression and reduced survival rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study identified that CHI3L1 was an oncogene in PTC and promotes tumor cell proliferation associated with downregulating the TP53 pathway.
