ASF1B and cancer: We also investigated ASF1B mRNA expression levels in 33 cancer tissues using the CCLE database and found that ASF1B mRNA was highly expressed in B‐cell acute lymphoblastic leukemia (ALL), T‐cell ALL, other leukemias, Burkitt lymphoma, other B‐cell lymphomas, and diffuse large B‐cell lymphoma (DUBCL) (Figure 1D).
