MS4A4A and Sepsis: four of the identified hub genes [MYB proto-oncogene like 1 (MYBL1) and killer cell lectin-like receptor G1 (KLRG1) form module “midnight blue”, stomatin (STOM) and membrane spanning 4-domains A4A (MS4A4A) from module “cyan”], predicted to be potential biomarkers for pediatric sepsis in intramodular analysis and with little known in sepsis, were further assessed for their difference in expression between 45 septic children and 16 controls (Table 4) by qPCR.
