Abstract Extramammary Paget’s disease is a rare malignant tumor of the skin that occurs primarily in genitocrural region. Although prognosis extramammary with distant metastasis poor, an effective therapy has not been established. Because Janus kinase 2 attracted attention as therapeutic target several cancers, we investigated expression protein and relationship between its level clinical signi...
Activation of Janus kinase 2 (JAK2) plays a critical role in normal hematopoiesis and leukemogenesis. Dawson et al. (2009; JAK2 phosphorylates histone H3Y41 and excludes HP1alpha from chromatin. Nature 461, 819-822) report that JAK2 performs this function by displacing the heterochromatin protein HP1α from chromatin through phosphorylation of histone H3.
Heterozygous STAT1 gain-of-function (GOF) mutations are associated with chronic mucocutaneous candidiasis and a broad spectrum of infectious, inflammatory, and vascular manifestations. We describe therapeutic failures with the Janus Kinase (JAK) inhibitor ruxolitinib in 2 STAT1 GOF patients with severe invasive or cutaneous fungal infections.
Janus kinases (JAKs) are receptor-associated multidomain tyrosine kinases that act downstream of many cytokines and interferons. JAK kinase activity is regulated by the adjacent pseudokinase domain via an unknown mechanism. Here, we report the 2.8-Å structure of the two-domain pseudokinase-kinase module from the JAK family member TYK2 in its autoinhibited form. We find that the pseudokinase and...
BACKGROUND AND PURPOSE Endothelin-1 (ET-1) is suggested to be a major cause of cerebral vasospasm after subarachnoid hemorrhage. However, the mechanism of ET-1-induced contraction in cerebral arteries remains unclear. This study was undertaken to demonstrate the possible role of protein tyrosine kinase (PTK), mitogen-activated protein kinase (MAPK), and protein kinase C (PKC) in ET-1-induced co...
Janus-activated kinases (JAK) are the mediators of a variety of cytokine signals via their cognate receptors that result in activation of intracellular signaling pathways. Alterations in JAK1, JAK2, JAK3, and TYK2 signaling contribute to different disease states, and dysregulated JAK–STAT signaling is associated with hematologic malignancies, autoimmune disorders, and immune-deficient condition...
