  • In this issue of Blood , Takahashi and colleagues have helped clarify the validity of using peripheral blood for monitoring the JAK2-V617F allele burden among the myeloproliferative neoplasms. (ashpublications.org)
  • The expression of RUNX1 mutant in ASXL1 -mutated myeloid cells augmented proliferation, blocked differentiation, and increased self-renewal activity. (biomedcentral.com)
  • This leads to uncontrolled proliferation, morphological transformation and anti-apoptotic effects. (umbc.edu)
  • Joshua Brody, MD, Director of the CLL/Lymphoma Immunotherapy Program, Icahn School of Medicine at Mount Sinai, New York, who was not involved in these trials, commented: "CLL is an extremely prevalent disease affecting nearly 200,000 patients in the United States. (ascopost.com)
  • There are a number of therapeutic strategies for doing this which, in general, are aimed at improving the anemia, or controlling the hyperproliferative manifestations of the disease (constitutional symptoms and painful splenitis). (fcarreras.org)
  • These patients are commonly treated with JAK2 inhibitors, but their disease progresses despite that therapy, so we're also trying to identify how the disease is able to worsen even in the setting of JAK2 inhibition," said Oh, who treats patients at Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine.

  • The researchers conducted a deep dive into the genetics of these tumors, both during the slow chronic phase and after the disease had transformed into the aggressive form while patients were taking JAK2 inhibitors. (technologynetworks.com)
  • The reason for the myeloid bias in these diseases is unclear, given the role of JAK2 downstream of numerous cytokine receptors, but could reflect qualitative differences in the consequences of JAK2V617F in the context of different receptors. (oncohemakey.com)
  • Patients with early phase (also known as chronic phase [CP]) disease usually respond to treatment with ABL tyrosine kinase inhibitors (TKIs), although some patients who respond initially later become resistant. (ca.gov)
  • FLT3 ( FMS -related tyrosine kinase 3) acts as an oncogene in myeloid neoplasms which is associated with several signal transduction pathways. (hindawi.com)
