SUCNR1 and necrotizing enterocolitis: The western blot results revealed that SUCNR1 expression was significantly upregulated in the NEC group compared with the control group (p < 0.05), and SUCNR1 expression was further increased in the NEC+Succi group (p < 0.05), whereas SUCNR1‐neutralizing antibody treatment reversed this effect (p < 0.05; Figure 6a,b).
