Janus Kinase 2 Inhibitor AG490 Inhibits the STAT3 Signaling Pathway by Suppressing Protein Translation of gp130.
The binding of interleukin-6 (IL-6) cytokine family ligands to the gp130 receptor complex activates the Janus kinase (JAK)/ signal transducer and activator of transcription 3 (STAT3) signal transduction pathway, where STAT3 plays an important role in cell survival and tumorigenesis. Constitutive activation of STAT3 has been frequently observed in many cancer tissues, and thus, blocking of the g...
متن کاملInhibition of janus kinase 2 by compound AG490 suppresses the proliferation of MDA-MB-231 cells via up-regulating SARI (suppressor of AP-1, regulated by IFN)
Objective(s): The Janus kinase-signal transducers and activators of transcription signaling pathway (JAK/STAT pathway) play an important role in proliferation of breast cancer cells. Previous data showed that inhibition of STAT3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. This study aims to investigate the effect and associated mechanisms...
متن کاملThe structural basis of Janus kinase 2 inhibition by a potent and specific pan-Janus kinase inhibitor.
JAK2, a member of the Janus kinase (JAK) family of protein tyrosine kinases (PTKs), is an important intracellular mediator of cytokine signaling. Mutations of the JAK2 gene are associated with hematologic cancers, and aberrant JAK activity is also associated with a number of immune diseases, including rheumatoid arthritis. Accordingly, the development of JAK2-specific inhibitors has tremendous ...
متن کاملPrevalence of Janus Kinase 2 mutations in patients with unusual site venous thrombosis.
We aimed to study patients with splanchnic vein thrombosis (SVT) and cerebral vein thrombosis (CVT) searching for JAK2 mutations. We evaluated 14 patients (median age: 41.5 years) with portal vein thrombosis (PVT) = 7; mesenteric vein thrombosis (MVT) = 3; and CVT = 4. JAK2 V617F was assessed by allele specific PCR of peripheral blood DNA. In addition, DNA was sequenced for other JAK2 mutations...
متن کاملLong term association of the cytokine receptor gp130 and the Janus kinase Jak1 revealed by FRAP analysis.
Signal transduction through cytokine receptors is mediated mainly by non-covalently associated Jak tyrosine kinases. By confocal microscopy, the cytokine receptor gp130 and Jak1, fused with either yellow (YFP) or cyan (CFP) fluorescent protein, were found to be colocalized predominantly at intracellular vesicular structures and at the plasma membrane. Quantitative fluorescence recovery after ph...
