In light of this, we endeavored to identify diagnostic gene candidates for MDD in individuals with comorbid anorexia.Methods: Gene expression data pertaining to MDD and healthy controls (HC) were retrieved from the Gene Expression Omnibus (GEO) database. Utilizing Limma and weighted gene co-expression network analysis (WGCNA), key MDD-associated genes were meticulously screened. Subsequently, these genes were cross-referenced with established anorexia-related genes to pinpoint common genetic factors shared between MDD and anorexia. Further refinement was conducted using Cytoscape software to identify hub-genes. Ultimately, animal experiments were conducted to validate and confirm the findings.Results: We identified a total of 214 genes that are commonly associated with both MDD and anorexia. These genes were found to be enriched in inflammatory and immune-related pathways. Among these 214 genes, six were distinguished as hub-genes: IL10, ITGAM, PTPRC, IL13, STAT5B, and JAK2. Immune infiltration analysis further revealed that all these hub-genes exhibited associations with multiple immune cell types. Animal experiments demonstrated that, compared to control mice, the model group exhibited significantly elevated expression levels of PTPRC, STAT5B, and JAK2.Conclusion: Through the application of bioinformatics analysis and animal experimentation, we have pinpointed three hub-genes (PTPRC, STAT5B, and JAK2) that hold potential as both diagnostic biomarkers and therapeutic targets for MDD accompanied with anorexia.Keywords: major depressive disorder, anorexia, inflammation, bioinformatics analysis, differentially expressed genes |
