PIK3CB and Sepsis: qPCR results showed that the expression of S100A9, PCBP1, PIK3CB, FOXO1, and TMEM59 was consistent with the public dataset, among which S100A9, PIK3CB, and TMEM59 were significantly overexpressed in sepsis, whereas PCBP1 and FOXO1 were significantly underexpressed in sepsis (Figure S1).
