Objective: To predict key immune-related genes in placental implantation disorders using bioinformatics methods. Methods: In this study, the dataset GSE189267 was selected from the GEO database. Differential expression analysis of genes in each group was performed using R software (“limma” R package) to identify differentially expressed genes (DEGs) with statistical significance. Subsequently, bioinformatics analysis methods, including Gene Ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, weighted gene co-expression network analysis (WGCNA), protein-protein interaction network analysis, and gene set enrichment analysis (GSEA), were employed to determine immune-related genes significantly associated with placental implantation disorders. Results: A total of 93 DEGs highly associated with placental implantation disorders were identified. Further analysis using WGCNA revealed 17 immune-related genes significantly associated with placenta percreta. Among them, leptin (LEP), chorionic somatomammotropin 1 (CSH1), and chorionic somatomammotropin 2 (CSH2) were identified as the top three hub genes. Single-gene GSEA analysis showed that LEP may be involved in membrane fission, multivesicular body organization, and nuclear membrane reorganization, while CSH1 and CSH2 were involved in similar biological processes, including regulation of RAC protein signal transduction and SRP-dependent cotranslational protein membrane targeting. Conclusion: This study suggests that LEP, CSH1, and CSH2 are key immune-related genes in placenta percreta. They may participate in the development of placenta percreta through mechanisms such as membrane fission, multivesicular body organization, nuclear membrane reorganization, regulation of RAC protein signal transduction, and SRP-dependent cotranslational protein membrane targeting.
