Functional enrichment analysis, pathway analysis, and the construction of protein\u2013protein interaction (PPI) networks were performed on core genes within these modules to pinpoint hub genes. The GSE25906 dataset was utilized as a validation cohort to evaluate the diagnostic significance of the hub genes. Immunohistochemistry assays were employed to validate the protein expression levels of these genes in placental tissues from both preeclampsia and control groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Through WGCNA, 33 co-expression modules were identified, with 4 modules significantly associated with multiple clinical traits (\u22653). Among these, 75 core genes were highlighted, predominantly enriched in pathways related to the adaptive immune response and platelet activation. Notably,\n                      <jats:italic>TYROBP, PLEK, LCP2, HCK, and ITGAM<\/jats:italic>\n                      emerged as hub genes with high PPI network scores and strong diagnostic potential, all prominently associated with immunity-related pathways. Protein expression analysis revealed that these genes were downregulated in placental tissues from preeclampsia patients compared to healthy controls.\n                    <\/jats:p>\n
