Heterodimeric JAK-STAT Activation as a Mechanism of Persistence to JAK2 Inhibitor Therapy [PDF]

, 2014
The identification of somatic activating mutations in JAK21–4 and in the thrombopoietin receptor (MPL)5 in the majority of myeloproliferative neoplasm (MPN) patients led to the clinical development of JAK2 kinase inhibitors6,7.

Myelofibrosis, JAK2 inhibitors and erythropoiesis [PDF]

Leukemia, 2013
The term myeloproliferative disorders was introduced by William Dameshek1 in 1951 to describe four different diseases with a related pathogenesis: polycythaemia vera (PV), essential thrombocythaemia (ET), primary myelofibrosis (PMF) and chronic myeloid leukaemia. The discovery of the Philadelphia chromosome and the fusion gene BCR-ABL has permitted the

DNA damage stress and inhibition of Jak2-V617F cause its degradation and synergistically induce apoptosis through activation of GSK3β. [PDF]

PLoS ONE, 2011
The cytoplasmic tyrosine kinase Jak2 plays a crucial role in cytokine receptor signaling in hematopoietic cells. The activated Jak2-V617F mutant is present in most cases of BCR/ABL-negative myeloproliferative neoplasms and constitutively activates ...

DENDRITIC CELL DIFFERENTIATION BLOCKED BY PRIMARY EFFUSION LYMPHOMA-RELEASED FACTORS IS PARTIALLY RESTORED BY INHIBITION OF P38 MAPK [PDF]

, 2010
To better understand the molecular mechanisms underlying the dendritic cell (DC) defects in cancer, we analyzed which signaling pathway is implicated in the abnormal monocyte differentiation into DC determined by the presence of Primary effusion lymphoma

JAK2 Gets Histone H3 Rolling [PDF]

Cancer Cell, 2009
Activation of JAK2 is implicated in normal hematopoiesis as well as oncogenic transformation. A paper in the recent issue of Nature demonstrates that phosphorylation of histone H3 by JAK2 releases the transcriptional repressor HP1alpha from chromatin, resulting in gene transcription.

Legumain Restrains Granuloma Formation by Inhibiting mTORC1/STAT1‐Mediated M1 Macrophage Polarization in Sarcoidosis

Advanced Science, EarlyView.
Legumain (LGMN) is upregulated in macrophages during sarcoid‑like granuloma formation. Macrophage‑derived LGMN binds to integrin αvβ3 and suppresses mTORC1/STAT1 signaling to restrain M1 macrophage polarization. Intratracheal delivery of lipid nanoparticles carrying Lgmn plasmid DNA (pDNA) elevates LGMN expression and effectively attenuates pulmonary ...

TYK2-induced phosphorylation of Y640 suppresses STAT3 transcriptional activity [PDF]

, 2017
STAT3 is a pleiotropic transcription factor involved in homeostatic and host defense processes in the human body. It is activated by numerous cytokines and growth factors and generates a series of cellular effects.

JAK2 V617F negative essential thrombocythemia [PDF]

Medical Journal Armed Forces India, 2013
Essential thrombocythemia (ET) is an acquired myeloproliferative disorder (MPD), characterized by persistent peripheral thrombocytosis and a tendency for thrombosis and hemorrhage.1 Erythromelalgia is a kind of cutaneous manifestation, which appears as a thrombotic complication in patients with myeloproliferative disorders such as essential ...

Endogenous Ceramide 24:1 Constrains Th17‐Driven Neutrophilic Inflammation by Antagonizing EP2 Signaling

Advanced Science, EarlyView.
Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.
