Proinflammatory cytokines such as TNFα are elevated in patients with myeloproliferative neoplasms (MPN), but their contribution to disease pathogenesis is unknown. Here we reveal a central role for TNFα in promoting clonal dominance of JAK2(V617F) expressing cells in MPN. We show that JAK2(V617F) kinase regulates TNFα expression in cell lines and primary(More)
Sequestration in the bone marrow niche may allow leukemic stem cells to evade exposure to drugs. Because the CXCR4/SDF-1 axis is an important mechanism of leukemic stem cell interaction with marrow stroma, we tested whether plerixafor, an antagonist of CXCR4, may dislodge chronic myeloid leukemia (CML) cells from the niche, sensitizing them to tyrosine(More)
