Relative to the control, the SOD1 protein level was decreased to 66.18% (p < 0.05), at 8 h after infection, but at 16 h after infection, it was reversed to a level close to the control (Figure 3(b)); SOD2 protein level was increased to 186.9% (p < 0.05) at 8 h after infection, then decreased to 65.5% (p < 0.05) at 16 h after infection (Figure 3(d)); CAT protein level was decreased to 66.8% (p < 0.05) at 16 h after infection (Figure 3(f)); and GPX4 protein levels were consistently increased to 144.1% (p < 0.05) and 183.5% (p < 0.05) at 8 and 16 h after infection, respectively (Figure 3(h)). The gene discussed is CAT; the disease is infection.
