This paper aims to identify differentially expressed genes (DGEs) in pancreatic cancer tissues using bioinformatics methods, elucidate the functions and signaling pathways of these DGEs, screen out signaling pathways related to the extracellular matrix (ECM), determine the relationship between ECM pathway research and pancreatic cancer, and identify potential biomarkers of the ECM in pancreatic cancer. Sample data of pancreatic cancer were downloaded from the Gene Expression Omnibus (GEO) database. Based on the chip data from GSE91035, R language was used to screen DGEs in the data. Gene Ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed on the DGEs related to pancreatic cancer. The GSEA database was utilized to visualize the ECM pathway and identify key genes. The GEPIA2 database was employed to verify the relationship between the expression of these key genes and prognosis. A total of 3023 DGEs were identified, with 1803 upregulated and 1220 downregulated genes. Among them, genes related to the ECM included COL1A1, LAMB3, COMP, FN1, THBS2, LAMC2, ITGA11, ITGB6, COL4A5, and HMMR. Verification was conducted to confirm that LAMB3, ITGB6, and HMMR are associated with the occurrence and development of pancreatic cancer. The DGEs in this dataset primarily affect the occurrence and development of pancreatic cancer by participating in biological processes such as antigen processing and presentation, ECM receptor interaction, cell adhesion molecules, and cell adhesion. It was determined that genes related to the ECM are crucial in pancreatic cancer. Through the analysis of DGEs in pancreatic cancer, this study identified genes related to the ECM as key targets of influence. %K 胰腺癌， %K 差异基因， %K 生物信息学， %K 细胞外基质
