In contrast, studies of SRPK1 in hematopoietic and lymphoid malignancies are rare and mostly focused on leukemias, such as acute adult T-cell leukemia [18], chronic myeloid leukemia [27, 28], acute lymphoblastic leukemia [29], and acute myeloid leukemia [19, 20]. The gene discussed is SRPK1; the disease is leukemia.
