The results of our in vitro experiments with cultured cells and in vivo experiments using the nude mice bearing U2932 xenografts were corroborated by the analyses of clinical samples using TCGA public datasets, which demonstrated drastic overexpression of both PRDX1 and PRDX2 in DLBCL tissues of the patients. This evidence concerns the gene PRDX1 and diffuse large B-cell lymphoma.
