To address this unmet clinical need, this study aimed to screen potential biomarkers for CRC drug resistance and prognosis through integrated bioinformatics analysis and clinical sample validation.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We analyzed Gene Expression Omnibus (GEO) database GSE153412 to screen differentially expressed genes (DEGs) between 5-fluorouracil (5-FU)-resistant and sensitive CRC cells (|log2FC|\u2009>\u20091.0, adj P\u2009<\u20090.05). Gene set enrichment analysis (GSEA) was used for pathway enrichment, Weighted gene co-expression network analysis (WGCNA) to identify resistance-related modules (correlation > 0.7, P\u2009<\u20090.01), and Protein-protein interaction (PPI) networks to screen hub genes. Their prognostic value was evaluated in TCGA-COAD, along with IC50 correlation. Finally, qPCR verified biomarker expression in clinical CRC samples.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n There were altogether 1033 DEGs screened. Through GSEA, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and Gene Ontology (GO) terms enriched by the DEGs were obtained. By PPI network construction, hub genes were screened. In TCGA-COAD datasets,\n CAV1 (P<\/jats:italic>\n \u2009\n =<\/jats:italic>\n \u2009\n 0.018)<\/jats:italic>\n ,\n CDH1 (P<\/jats:italic>\n \u2009\n =<\/jats:italic>\n \u2009\n 0.049)<\/jats:italic>\n ,\n CXCL8 (P<\/jats:italic>\n \u2009\n =<\/jats:italic>\n \u2009\n 0.00068)<\/jats:italic>\n ,\n CD24 (P<\/jats:italic>\n \u2009\n =<\/jats:italic>\n \u2009\n 0.00017)<\/jats:italic>\n ,\n NR3C1 (P<\/jats:italic>\n \u2009\n =<\/jats:italic>\n \u2009\n 0.016)<\/jats:italic>\n , and\n ZEB1 (P<\/jats:italic>\n \u2009\n =<\/jats:italic>\n \u2009\n 0.042)<\/jats:italic>\n were also related to CRC prognosis. The correlation analysis of key genes and drug resistance suggested the emergence of\n CDH1<\/jats:italic>\n ,\n CAV1<\/jats:italic>\n ,\n NR3C1<\/jats:italic>\n , and\n ZEB1<\/jats:italic>\n , which was also examined by clinical data validation.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Integrated bioinformatics and clinical validation analyses identified\n CDH1<\/jats:italic>\n ,\n CAV1<\/jats:italic>\n ,\n NR3C1<\/jats:italic>\n , and\n ZEB1<\/jats:italic>\n as key biomarkers for CRC. These genes were significantly associated with 5-FU resistance and CRC prognosis, as supported by their dysregulated expression in clinical samples, highlighting their mechanistic roles in the CRC drug resistance pathways.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/15330338261430993","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T18:14:17Z","timestamp":1773252857000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["CDH1<\/i>\n ,\n CAV1<\/i>\n ,\n NR3C1<\/i>\n , and\n ZEB1<\/i>\n are Potential Biomarkers in Colorectal Cancer Drug Resistance and Prognosis"],"prefix":"10.1177","volume":"25","author":[{"given":"Pengfei","family":"Wu","sequence":"first","affiliation":[{"name":"the Second Affiliated Hospital of Soochow University"},{"name":"Department of General Surgery, The People's Hospital of Rugao, Rugao Hospital Affiliated to Nantong University, Rugao City, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guodong","family":"Liu","sequence":"additional","affiliation":[{"name":"Suqian First Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lening","family":"Shao","sequence":"additional","affiliation":[{"name":"the Second Affiliated Hospital of Soochow University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9777-3041","authenticated-orcid":false,"given":"Yongyou","family":"Wu","sequence":"additional","affiliation":[{"name":"the Second Affiliated Hospital of Soochow University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,3,10]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.4251\/wjgo.v17.i10.110661"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(25)01635-6"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.suc.2023.11.009"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/cells13030245"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-025-09025-8"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopha.2021.112091"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-020-19173-2"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pharmthera.2019.107447"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.20517\/cdr.2022.136"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.32471\/exp-oncology.2312-8852.vol-43-no-2.16314"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/30.1.207"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12885-022-09417-3"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/28.1.27"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-9-559"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.2147\/OTT.S258439"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-022-30142-9"},{"issue":"5","key":"e_1_3_3_18_2","first-page":"1857","article-title":"Caveolin-1 in multi drug resistance and two-field lymphadenectomy for thoracic esophageal squamous cell carcinoma","volume":"30","author":"Fang W","year":"2017","unstructured":"Fang W, Ruan W, Lin S, et al.
