We visualized the heatmap of the expression levels of core genes in the samples (Figure 10a for GSE58294 and Figure 10b for GSE154918), and found that the core genes (UQCRQ, USMG5 [ATP5MD], COX6C, NDUFB3, ATP5L [ATP5MG], COX7C, NDUFA1, NDUFA4) were highly expressed in septic shock and stroke samples, while lowly expressed in normal samples. This evidence concerns the gene COXFA4 and stroke disorder.
