The integrins are a large family of cell adhesion molecules that are essential for the regulation of cell growth and function. The identification of key roles for integrins in a diverse range of diseases, including cancer, infection, thrombosis and autoimmune disorders, has revealed their substantial potential as therapeutic targets. However, so far,(More)
Cardiac /S-l adrenoceptors respond to sympathetic nerve stimulation (SNS), but it is not clear that SNS evokes fi-2 adrenoceptor-mediated vasodilation. Sensitivity of B adrenoceptors to catecholamines and to SNS was evaluated in dogs. Norepinephrine (NE) and epinephrine (E) were equipotent vasoconstrictors (femoral artery blood flow or gracilis(More)
The concept that the positive inotropic effect of cardiac glycosides is dependent on the contractile state of the myocardium was tested. Isolated left atria of rabbits, when driven electrically at 15, 30, 60 and 120/min (at 30, 33, or 37°C), responded to ouabain (1 yug/ml) in proportion to the number of contractions and not to the time of exposure or(More)
Protein tyrosine phosphatase receptor delta (PTPRD) is a member of a large family of protein tyrosine phosphatases which negatively regulate tyrosine phosphorylation. Neuroblastoma is a major childhood cancer arising from precursor cells of the sympathetic nervous system which is known to acquire deletions and alterations in the expression patterns of(More)
