Box plot showing GPX1 expression levels in tumors based on sample types, histological subtypes, and French American British classification via UALCAN database (P<0.05). (A) The box plot shows the relative expression of GPX1 in normal and KIRP samples; (B) expression of GPX1 in LGG based on histological subtypes, respectively, astrocytoma, oligoastrocytoma, oligodendroglioma; (C) expression of GPX1 in LAML based on French American British classification (M0, M1, M2, M3, M4, M5, M6, M7). GPX1, glutathione peroxidase-1; LGG, low grade glioma; LAML, acute myeloid leukemia.
