Next, we mined the database Cancer Cell Line Encyclopedia (CCLE) [5] to examine SLFN11 expression levels across different histologic subtypes of B-cell-derived cancer cell lines: B-ALL (B-cell acute lymphoblastic leukemia), GCB-DLBCL (germinal center B-cell like-diffuse large B-cell lymphoma), BL (Burkitt lymphoma), B-CLL (B-cell chronic lymphocytic leukemia), ABC-DLBCL (activated B-cell like-diffuse large B-cell lymphoma) and PCM (plasma cell myeloma). The gene discussed is SLFN11; the disease is plasma cell myeloma.
