As shown in Fig. 1B, SLC31A1 expression is upregulated in lymphoid neoplasm, diffuse large B-cell lymphoma (DLBC), and cerebral low-grade leukaemia (LGG), but downregulated in acute myeloid leukaemia (LAML) and no significant difference in expression was found with other malignancies (Fig. S1). This evidence concerns the gene SLC31A1 and diffuse large B-cell lymphoma.
