GH signaling begins with activation of the GH receptor (GHR)-associated cytoplasmic tyrosine kinase, Janus kinase-2. GH-induced Janus kinase-2 activation leads to engagement of several signaling pathways, including the extracellular signal-regulated kinase (ERK), mitogen-activated protein kinase, phosphoinositol 3-kinase, and signal transducer and activator of transcription-5 (STAT5) pathways. ...
Abscisic acid (ABA) induces a rapid and transient mitogen-activated protein (MAP) kinase activation in barley aleurone protoplasts. MAP kinase activity, measured as myelin basic protein phosphorylation by MAP kinase immunoprecipitates, increased after 1 min, peaked after 3 min, and decreased to basal levels after ~5 min of ABA treatment in vivo. Antibodies recognizing phosphorylated tyrosine re...
BACKGROUND Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is characterized by a gene-expression profile similar to that of BCR-ABL1-positive ALL, alterations of lymphoid transcription factor genes, and a poor outcome. The frequency and spectrum of genetic alterations in Ph-like ALL and its responsiveness to tyrosine kinase inhibition are undefined, especially in adolesc...
The signaling pathways triggered by adherence of Candida albicans to the host cells or extracellular matrix are poorly understood. We provide here evidence in C. albicans yeasts of a p105 focal adhesion kinase (Fak)-like protein (that we termed CaFak), antigenically related to the vertebrate p125Fak, and its involvement in integrin-like-mediated fungus adhesion to vitronectin (VN) and EA.hy 926...
The phosphorylation of insulin receptor substrate 1 (IRS-1) on tyrosine residues by the insulin receptor (IR) tyrosine kinase is involved in most of the biological responses of insulin. IRS-1 mediates insulin signaling by recruiting SH2 proteins through its multiple tyrosine phosphorylation sites. The phosphorylation of IRS-1 on serine/threonine residues also occurs in cells; however, the parti...
Serine residues of the human insulin receptor (HIR) may be phosphorylated and negatively regulate the insulin signal. We studied the impact of 16 serine residues in HIR by mutation to alanine and co-overexpression in human embryonic kidney (HEK) 293 cells together with the docking proteins insulin receptor substrate (IRS)-1, IRS-2, or (SHC) Src homologous and collagen-like. As a control, IRS-1 ...
preeclampsia is an important pregnancy disorder with serious maternal and fetal complications which its etiology has not been completely understood yet. early diagnosis and management of disease could reduce its potential side effects. the vascular endothelial growth factor (vegf) family including vegf-a is the most potent endothelial growth factor which induces angiogenesis and endothelial cel...
The Met receptor tyrosine kinase has been shown to be overexpressed or mutated in a variety of solid tumors and has, therefore, been identified as a good candidate for molecularly targeted therapy. Activation of the Met tyrosine kinase by the TPR gene was originally described in vitro through carcinogen-induced rearrangement. The TPR-MET fusion protein contains constitutively elevated Met tyros...
More than 30% of acute myeloid leukemia (AML) patients possess activating mutations in the receptor tyrosine kinase FMS-like tyrosine kinase 3 or FLT3. A small-molecule inhibitor of FLT3 (known as quizartinib or AC220) that is currently in clinical trials appears promising for the treatment of AML. Here, we report the co-crystal structure of the kinase domain of FLT3 in complex with quizartinib...
