1. Tumour necrosis factor-alpha (TNF alpha) increases the expression of the adhesion molecule intercellular adhesion molecule-1 (ICAM-1) on cultured endothelial and epithelial cells and modulation of this may be important in controlling inflammation. Activation of tyrosine kinase(s) is known to

The effects of sodium orthovanadate, an inhibitor of protein tyrosine phosphatases, on the endothelial nitric oxide (NO) pathway were studied in vitro. Vanadate caused endothelium-dependent relaxations in isolated porcine coronary arteries, which were abolished by N omega-nitro-L-arginine methyl ester. The

This study was designed to examine whether or not intramural delivery of ST638 (a specific tyrosine kinase inhibitor) with biodegradable stent can suppress the restenotic changes of the coronary artery in vivo. Clinical and animal studies demonstrated that restenosis after

Polymorphonuclear leukocytes (neutrophils) release a variety of toxic agents--proteins and reactive oxygen species (ROS)--that are used to inactivate foreign microorganisms in the non-specific immune response. This study was undertaken to compare intracellular signalling pathways that lead to the ROS production

Treatment of high-metastatic Lewis lung carcinoma A11 cells with sodium orthovanadate, a phosphotyrosine phosphatase inhibitor, resulted in a dose- and time-dependent suppression of cell spreading on various extracellular matrix components such as Matrigel, fibronectin, laminin and type IV collagen, while
