The phosphorylation of proteins at tyrosine residues is critical in cellular signal transduction, neoplastic transformation and control of the mitotic cycle. These mechanisms are regulated by the activities of both protein-tyrosine kinases (PTKs) and protein-tyrosine phosphatases (PTPases). As in the PTKs, there are two classes of PTPases: membrane(More)
BACKGROUND Angiogenesis is the target of several agents in the treatment of malignancies, including renal cell carcinoma (RCC). There is a real need for surrogate biomarkers that can predict selection of patients who may benefit from antiangiogenic therapies, prediction of disease outcome and which may improve the knowledge regarding mechanism of action of(More)
INTRODUCTION The aim of this study is to review 10 years experience of retroperitoneoscopy procedures. METHODS A total of 600 patients treated between 1995 and 2007 by retroperitoneoscopy (nephrectomy, partial and total nephrectomy, adrenalectomy, pyeloplasty, renal cyst, calyceal diverticulectomy) were reviewed for per, peri and postoperative(More)
To detect heterologous expression of receptors coupled via G proteins to the stimulation of adenylate cyclase in Xenopus laevis oocytes, the receptor of interest is coexpressed with the cystic fibrosis transmembrane conductance regulator (CFTR)--a cAMP-dependent Cl- channel. The binding of an agonist to the expressed receptor stimulates adenylate cyclase(More)
