GATA1 and diffuse large B-cell lymphoma: Subsequently, we did GSEA of single gene GATA1 and found three pathways: PROTEASOME (P = 0.00 FDR = 0.0029), OXIDATIVE PHORYLATION (P = 0.013 FDR = 0.06), and PARKINSONS DISEASE (P = 0.028 FDR = 0.07), which can regulate the proliferation of DLBCL (Figure 4(c)).
