GAPDH and ACTB expression profiles determined by RT-PCR were highly similar (Figure 3), and higher GAPDH expression in sepsis compared to SIRS was confirmed by QGP in this study (Figure 5B) and previously in sepsis compared to age- and sex-matched outpatients by Cummings et al. (2014) [49]. This evidence concerns the gene ACTB and systemic inflammatory response syndrome.
