Confirmatory GPX1 enzyme-linked immunosorbent assay (ELISA) Kit analysis was then performed, and the results demonstrated that GPX1 expression in the PT group was significantly decreased compared to the sham group, whereas allicin significantly increased the expression level of GPX1 in the infarct area of mice with cerebral infarction, consistent with our proteomic results (Fig. 3H, I). Here, GPX1 is linked to brain infarction.
