A nomogram model was developed, and biomarker functions were explored through enrichment analysis, immunoinfiltration analysis, transcription factors (TFs) and microRNA (miRNA) prediction, and drug prediction. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed to validate the expression of biomarkers in sepsis and control group.Results: There were 3,899 differential expressed genes (DEGs) in sepsis, with 141 related to glucose metabolism. Eleven hub genes were identified from the PPI network, and six biomarkers were selected through machine learning and area under the curve (AUC) validation. Notably, PPARG (OR = 1.0730, 95% CI: 1.0330– 1.1160) and AKT1 (OR = 0.9211, 95% CI: 0.8569– 0.9902) had causal relationships with sepsis. The diagnostic nomogram based on these biomarkers showed good efficacy. Enrichment analysis suggested AKT1 inhibits sepsis development, while PPARG promotes it. Drug prediction indicated strong interactions between AKT1 and gigantol, and PPARG with echinatin. qRT-PCR showed reduced expression of PPARG and AKT1 in sepsis, aligning with bioinformatics predictions.Conclusion: In summary, AKT1 and PPARG are causally associated with sepsis, showing diagnostic potential. AKT1 may inhibit sepsis development, while PPARG may promote it. These findings provide valuable insights for sepsis diagnosis and therapeutic drug development.Keywords: sepsis, glucose metabolism, transcriptomics, Mendelian randomization, biomarkers |
