Figure 4. The impact of serum cytokines on the prognosis of the old IRI mice. (A) The canonical serum cytokines between the O-O: IRI to the old: IRI group and the Y-O: IRI to the old: IRI group. (B) Heat map of the O-O: IRI to the old: IRI group. (C) Heat map of the Y-O: IRI to the old: IRI group. (D) Gene Ontology Annotation was used to identify the molecular function of the differentially expressed cytokines (E) Gene Ontology Annotation was used to identify the cellular components of the differentially expressed cytokines (F) Gene Ontology Annotation was used to identify the biological process of differentially expressed cytokines (G) The KEGG pathways that changed significantly were those related to differentially expressed cytokines. (H) The protein-protein interaction network among the differentially expressed cytokines.
