Investigated TAM family receptor tyrosine kinase gene expression in response to small molecule inhibitors in glioblastoma multiforme

Not exact matches

The initial model for STAT signaling involves a specific cytokine binding to its cognate receptor and promoting the transphosphorylation of receptor associated tyrosine kinases from the Janus - activated kinase family (JAK).

Also, genes that code for receptor tyrosine kinases, a family of receptors on the surface of cells, may rearrange to form multiple distinct gene fusion partners, as evidenced in an article by Kulkarni, et al, on a translational study involving a patient who developed a BRAF fusion following treatment with a BRAF inhibitor1.

In 2005, the identification of an activating mutation in JAK2 (the V617F mutation) as a STAT5 - activating and disease - causing genetic alteration in a significant proportion of patients with myeloproliferative neoplasms (MPNs) has emphasized the oncogenic role of the JAK tyrosine kinases in hematologic malignancies.2 — 5 JAK2 is a member of the Janus tyrosine kinase family comprising three other mammalian non-receptor tyrosine kinases (JAK1, JAK3 and TYK2) that associate with cytokine receptors lacking intrinsic kinase activity to mediate cytokine - induced signal transduction and activation of STAT transcription factors.6 All JAKs share a similar protein structure and contain a tyrosine kinase domain at the C - terminus flanked by a catalytically inactive pseudokinase domain with kinase - regulatory activity, by an atypical SH2 domain and by a FERM domain that mediates association to the membrane - proximal region of the cytokine receptors.7, 8 Soon after the discovery of JAK2 V617F, we and others described that activating JAK1 mutations are relatively common in adult patients with T - cell acute lymphoblastic leukemia (ALL) and participate in ALL development allowing for constitutive activation of STAT5.9 — 11 Several STAT5 - activating JAK1 mutations were also reported in AML and breast cancer patients.10

Receptor tyrosine kinases of the Eph family and their ligands, the ephrins, represent an important cell communication system that controls a vast array physiological and disease processes.

In addition, at least some Eph receptors can also signal through non-canonical mechanisms that are independent of ligand binding and kinase activity, for example through interplay with other receptor tyrosine kinase families and with serine / threonine kinases.
