expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
OBJECTIVES Lymph node involvement is a key feature and an independent prognostic factor of oesophageal squamous cell carcinoma. However, an accurate and robust assay to predict the lymphatic spread of oesophageal squamous cell carcinoma is unavailable. The purpose of this study was to determine whether serum vascular endothelial growth factor-C (VEGF-C) and spleen tyrosine kinase levels are pot...
The protein tyrosine phosphatase PTPN22 inhibits T cell activation by dephosphorylating some essential proteins in the receptor (TCR)-mediated signaling pathway, such as lymphocyte-specific kinase (Lck), Src family kinases Fyn, and phosphorylation levels of Zeta-chain-associated kinase-70 (ZAP70). For first time, we have successfully produced CS transgenic mice which activity is suppressed. Not...
genistein is a soya isoflavone, which is found naturally in legumes, such as soybeans and chickpeas. the intraperitoneal administration of the optimum dose (200 mg/kg) of genistein 24 h and 15 minbefore irradiation (8 gy at a dose rate of 1.02 gy/min) recovered the deficit in protein content (28.63±1.44%) and the dna content (21.61±8.19%) if an average of 5 intervals of autopsies 1st, 3rd, 7th,...
The major NaCl-stimulated protein-tyrosine kinase activity found in soluble thymus extracts, as measured by the phosphorylation of angiotensin I, is a 40-kDa enzyme known as p40 (Zioncheck, T. F., Harrison, M. L., and Geahlen, R. L. (1986) J. Biol. Chem. 261, 15637-15643). Antibodies prepared against p40 cross-react with a 72-kDa protein-tyrosine kinase (p72) from spleen or thymus that is close...
Spleen tyrosine kinase (SYK) is a cytoplasmic enzyme that promotes survival and proliferation of B cells. SYK inhibition has shown promising results in the treatment of arthritis and chronic lymphocytic leukemia (CLL). However, in other context, it has been shown that SYK overexpression in epithelial cancer cells induced senescence in p53-dependent mechanism, which underscored its antineoplasti...
