JAK2, the JAK2 V617F mutant and cytokine receptors
Recently, a unique recurrent somatic mutation was identified as a major molecular event in polycythemia vera, essential thrombocythemia and idiopathic myelofibrosis. Expression of this mutant in cytokine-dependent hematopoietic cell lines induces autonomous growth. This effect is enhanced by overexpression of cytokine receptors, and can be inhibited by

Combined Targeting of JAK2 and Bcl-2/Bcl-xL to Cure Mutant JAK2-Driven Malignancies and Overcome Acquired Resistance to JAK2 Inhibitors [PDF]
To design rational therapies for JAK2-driven hematological malignancies, we functionally dissected the key survival pathways downstream of hyperactive JAK2.

JAK2 is dispensable for maintenance of JAK2 mutant B-cell acute lymphoblastic leukemias [PDF]
Activating JAK2 point mutations are implicated in the pathogenesis of myeloid and lymphoid malignancies, including high-risk B-cell acute lymphoblastic leukemia (B-ALL). In preclinical studies, treatment of JAK2 mutant leukemias with type I JAK2 inhibitors (e.g., Food and Drug Administration [FDA]-approved ruxolitinib) provided limited single-agent ...

Recurrent numerical aberrations of JAK2 and deregulation of the JAK2-STAT cascade in lymphomas [PDF]
The Janus kinase 2 (JAK2)-signal transducers and activators of transcription (STAT) pathway plays an important role in hematological malignancies. Mutations and translocations of the JAK2 gene, mapped at 9p24, lead to constitutive activation of JAK2 and its downstream targets.

Cbl-mediated K63-linked ubiquitination of JAK2 enhances JAK2 phosphorylation and signal transduction
JAK2 activation is crucial for cytokine receptor signal transduction and leukemogenesis. However, the underlying processes that lead to full activation of JAK2 are unclear.

JAK2 Negative Polycythemia Vera
ABSTRACTPolycythemia vera (PV) is a stem cell disorder, characterized as a panhyperplastic, malignant, and neoplastic marrow disorder. Several reasons suggest that a mutation on the Janus kinase-2 gene (JAK2) is the most probable candidate gene involved in PV pathogenesis, as JAK2 is directly involved in intracellular signaling, following its exposure ...

PREFERENTIAL NUCLEAR ACCUMULATION OF JAK2V617F IN CD34+ BUT NOT IN GRANULOCYTIC, MEGAKARYOCYTIC OR ERYTHROID CELLS OF PATIENTS WITH PHILADELPHIA-NEGATIVE MYELOPROLIFERATIVE NEOPLASIA. [PDF]
Recently, Dawson et al. identified a previously unrecognized nuclear role for JAK2 in the phosphorylation of the tyrosine 41 of the histone H3 with the exclusion of HP1a from chromatin and resulting in a disregulation of several JAK2-regulated genes such

JAK2 Inhibitors: Are They the Solution? [PDF]
The discovery of the JAK2V617F mutation in patients with Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPN) started the era of targeted therapy for these diseases. Until now, patients had few treatment options available, which usually were restricted to hydroxyurea, interferon preparations, and chemotherapy in more aggressive cases ...
