This study aimed to identify molecular signatures associated with GDM-related placental pathology and evaluate their diagnostic and therapeutic implications.</div></div><div><h3>Methods</h3><div>Two bulk placental transcriptomic datasets (GSE70493 and GSE263483) and one single-cell dataset (GSE173193) were analyzed. Differential expression analysis, WGCNA, and machine-learning feature selection (LASSO and SVM-RFE) were used to identify candidate gene signatures. A two-gene logistic regression model was constructed and externally validated. Immune-cell correlation rewiring and single-cell <em>in silico</em>perturbation analysis explored immune-network alterations and regulatory roles of identified genes. A drug-prioritization framework was used for therapeutic screening.</div></div><div><h3>Results</h3><div>Intersecting WGCNA modules with differentially expressed genes identified 29 candidates enriched in antigen presentation and mononuclear phagocyte functions. Dual-algorithm selection converged on HLA-DQA2 and FGL2. The two-gene model achieved an AUC of 0.786 in the discovery cohort and 0.813 in the external validation cohort. Immune rewiring analysis indicated a shift toward M1 macrophage polarization. Single-cell perturbation analysis supported regulatory roles of HLA-DQA2 and FGL2 within the macrophage lineage. Drug analysis reaffirmed insulin, metformin, and glyburide as stable therapeutic anchors.</div></div><div><h3>Discussion</h3><div>The HLA-DQA2/FGL2 signature captures key aspects of placental immunometabolic dysregulation in GDM, including altered antigen presentation and macrophage-associated immune rewiring. This integrated framework provides candidate biomarkers for GDM risk stratification and generates computational hypotheses for future mechanistic and therapeutic studies.</div></div>","PeriodicalId":20203,"journal":{"name":"Placenta","volume":"183 ","pages":"Pages 82-93"},"PeriodicalIF":3.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148865152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
