SLC31A1 and lymphoid neoplasm: 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).
