Methods: The oxycodone anesthesia dataset GSE232804 profile was downloaded from the GEO database, generated by GPL20084. Differentially expressed genes (DEGs) were screened, and weighted gene co-expression network analysis (WGCNA), functional enrichment analysis, and protein-protein interaction (PPI) network construction and analysis were conducted. A heatmap of gene expression was generated. The Comparative Toxicogenomics Database (CTD) was used to identify diseases most related to core genes, and TargetScan was used to screen miRNAs regulating central DEGs. Results: A total of 171 DEGs were identified. GO analysis showed that in the BP category, they were primarily enriched in cellular response to corticotropin-releasing hormone, neuron differentiation, and regulation of synaptic plasticity. In the CC category, they were mainly enriched in the nucleus, transcription factor complex, and neuron cell body. In the MF category, they were focused on protein binding, transcription corepressor activity, and protein kinase activity. KEGG analysis showed enrichment in the MAPK signaling pathway, amphetamine addiction, NF-kappa B signaling pathway, and TNF signaling pathway. Core genes (Rasl11a, Map3k14, Dusp5, Dusp6, Arl4d, Kdm6b, Egr1, Egr3, Bcorl1) were identified in the PPI network. The soft-thresholding power in WGCNA analysis was set to 9, generating a total of eight modules. Five core genes (Dusp1, Egr1, Egr2, Fos, Nr4a1) were identified. The heatmap of core gene expression showed that Dusp1, Egr1, Egr2, Fos, and Nr4a1 were highly expressed in samples of oxycodone anesthesia post-surgery. CTD analysis revealed that the core genes (Dusp1, Egr1, Egr2, Fos, Nr4a1) were associated with immune system diseases, neurological diseases, arrhythmia, tachycardia, and digestive system abnormalities. Conclusion: Egr1 and Fos are highly expressed in oxycodone anesthesia samples post-surgery.展开更多
