Aims: The aims of this study are to discover dysregulated adipocytokine signaling pathway and pyroptosis-related genes to predict neonatal hypoxic-ischemic encephalopathy (HIE) occurrence.

Background: HIE is an important cause of infant death and long-term neurological sequelae. Current treatment options for HIE are relatively limited and the pathogenesis of HIE remains to be fully explored. This study investigated the alterations of adipocytokine signaling pathway and pyroptosis in neonatal HIE.

Objective: To reveal the alterations of adipocytokine signaling pathway and pyroptosis relevant to HIE occurrence.

Methods: Data on neonatal HIE were downloaded from the Gene Expression Omnibus (GEO) database. Pathway analyses of single-sample gene set enrichment analysis (ss- GSEA) and GSEA were performed on the adipocytokine signaling pathway and pyroptosis. Proportions of immune cells in a single sample were also calculated by ssGSEA and CIBERSORT algorithm. The relationship between the adipocytokine signaling pathway and pyroptosis was analyzed according to Pearson correlation analysis.

Results: The activities of KEGG pathways changed after the occurrence of HIE, and adipocytokine signaling pathway was activated with related overexpressed genes. For the three energy metabolisms, carbohydrate metabolism was enhanced; lipid metabolism showed increased fatty acids metabolism and decreased ability of fatty acids synthesis; metabolic levels of phosphate and phenylalanine in amino acid metabolism were elevated. Enhanced pyroptosis and relevant overexpressed genes were accompanied by increased immune cells. A positive connection between adipocytokine signaling pathway and pyroptosis was observed.

Conclusion: These results indicated that the adipocytokine signaling pathway may promote HIE occurrence by upregulating the expression of pyroptosis-related genes, providing a novel mechanism for HIE.
