CASP12 and necrotizing enterocolitis: The results of Western blotting showed that the protein expressions of caspase-12 in the NEC group at 24 h, 48 h and 72 h of NEC modeling were greater than those in the control group by 22.02%, 45.25%, and 77.12%, respectively (P < 0.05 at all 3 time-points) (Fig. 4, Table 5).
