CASP9 and Sepsis: Finally, we noticed that the levels of caspase-3/9 protein decreased in sepsis + miR-21 mimic group, while the levels of caspase-3/9 protein increased in sepsis + miR-21 inhibitor group [t value (caspase-3: NC versus SP) = 10.643, p < 0.01; t value (caspase-3: miR-21 mimic versus SP) = 4.089, p < 0.01; t value (caspase-3: miR-21 inhibitor versus SP) = 4.545, p < 0.01; t value (caspase-9: NC versus SP) = 7.345, p < 0.01; t value (caspase-9: miR-21 mimic versus SP) = 4.664, p < 0.01; t value (caspase-9: miR-21 inhibitor versus SP) = 2.681, p < 0.05] (Figures 7(g)–7(j)).
