SLC27A2 participates in the immune process of hematological tumors through T cell CD8 + and macrophages, In DLBCL, patients with low expression of SLC27A2 have poorer prognosis, while in AML, patients with high expression of SLC27A2 have poorer prognosis (Fig. S4). The gene discussed is SLC27A2; the disease is diffuse large B-cell lymphoma.
