To verify the authenticity of our data, the new DLBCL dataset GSE32918 (tissue RNA-seq results of DLBCL) and peripheral blood samples from the normal control group were screened again for limma analysis to detect differential genes, as well as their interaction with previously screened shared genes, to finally identify three core genes, GATA1, KLF1, and ACSL6 [22,23]. Here, KLF1 is linked to diffuse large B-cell lymphoma.
