Differential Intrinsic Enzymatic Activity of Syk and Zap-70 Protein-tyrosine Kinases*

Journal of Biological Chemistry, 1996
Syk and Zap-70 are related protein-tyrosine kinases implicated in antigen and Fc receptor signaling. While Zap-70 is restricted to T-cells and natural killer cells, Syk accumulates in B-cells, mast cells, platelets, and immature T-cells.

Molecular imaging predicts trastuzumab‐deruxtecan (T‐DXd) response in head and neck cancer xenograft models

Molecular Oncology, EarlyView.
Trastuzumab‐deruxtecan, a HER2‐targeting antibody‐drug conjugate, shows promising antitumor activity in head and neck squamous cell carcinoma with low HER2 expression. In vitro and in vivo studies demonstrated dose‐dependent cell death and tumor growth reduction in low HER2‐expressing cell lines, which correlated with drug accumulation measured using a

Oncogenes, Protein Tyrosine Kinases, and Signal Transduction

Journal of Biomedical Science, 1994
Many oncogenes encode protein tyrosine kinases (PTKs). Oncogenic mutations of these genes invariably result in constitutive activation of these PTKs. Autophosphorylation of the PTKs and tyrosine phosphorylation of their cellular substrates are essential events for transmission of the mitogenic signal into cells.

Role of Non Receptor Tyrosine Kinases in Hematological Malignances and its Targeting by Natural Products

Molecular Cancer, 2018
Tyrosine kinases belong to a family of enzymes that mediate the movement of the phosphate group to tyrosine residues of target protein, thus transmitting signals from the cell surface to cytoplasmic proteins and the nucleus to regulate physiological ...

Phosphorylation and Activation of the DNA Binding Activity of Purified Stat1 by the Janus Protein-tyrosine Kinases and the Epidermal Growth Factor Receptor (*)

Journal of Biological Chemistry, 1995
The activation of Janus protein-tyrosine kinases (Jaks) and the subsequent phosphorylation and activation of latent signal transducers and activators of transcription (Stats) are common elements in signal transduction through the cytokine receptor ...

Loss of primary cilia promotes EphA2‐mediated endothelial‐to‐mesenchymal transition in the ovarian tumor microenvironment

Molecular Oncology, EarlyView.
Loss of primary cilia in endothelial cells promotes EndMT and vascular abnormalities in the ovarian tumor microenvironment through EphA2 activation. Using human samples, in vitro models, and endothelial‐specific Kif3a‐knockout mice, we show that primary cilia loss drives the acquisition of cancer‐associated fibroblast‐like phenotypes, thereby ...

The fusion proteins TEL-PDGFRβ and FIP1L1-PDGFRα escape ubiquitination and degradation

Haematologica, 2009
Background Chimeric oncogenes encoding constitutively active protein tyrosine kinases are associated with chronic myeloid neoplasms. TEL-PDGFRβ (TPβ, also called ETV6-PDGFRB) is a hybrid protein produced by the t(5;12) translocation, FIP1L1-PDGFRα (FPα ...

Analysis of CD28 cytoplasmic tail tyrosine residues as regulators and substrates for the protein tyrosine kinases, EMT and LCK.

Journal of Immunology, 1997
The CD28 cell surface receptor provides an important costimulatory signal for T cells necessary for their response to Ag. Early events in CD28 signaling include recruitment and activation of phosphatidylinositol 3-kinase (PI3-kinase) and activation of ...
