SOD1 and COVID-19: CAT overexpression was accompanied by a significant increase in SOD1 mRNA levels in v-COVID-19 (p < 0.001, 3.2-fold increase; p = 0.001, 2.7-fold increase) and u-COVID-19 (p < 0.001, 2.1-fold increase; p = 0.017, 1.8-fold increase) placentae compared to the v-CTRL and u-CTRL subgroups (Figure 2B).
