Protein kinases are frequently mutated in human cancer and inhibitors of mutant protein kinases have proven to be effective anticancer drugs. We screened the coding sequences of 518 protein kinases (approximately 1.3 Mb of DNA per sample) for somatic mutations in 26 primary lung neoplasms and seven lung cancer cell lines. One hundred eighty-eight somatic(More)
The protein-kinase family is the most frequently mutated gene family found in human cancer and faulty kinase enzymes are being investigated as promising targets for the design of antitumour therapies. We have sequenced the gene encoding the transmembrane protein tyrosine kinase ERBB2 (also known as HER2 or Neu) from 120 primary lung tumours and identified(More)
Photodynamic therapy (PDT) requires oxygen to cause cellular and vascular tumor damage. Tissue oxygen concentration, in turn, is influenced by blood flow and blood oxygenation. Real-time clinical measurement of these hemodynamic quantities, however, is rare. This paper reports the development and application of a probe, combining diffuse reflectance(More)
Treatment side effects and decreased quality of life associated with androgen deprivation therapy (ADT) suggest the need for supportive services for prostate cancer (PC) patients receiving ADT. Nonetheless, uptake of services is low, suggesting that PC patients' preferences are not being addressed. We examined interest in supportive services and predictors(More)
BACKGROUND Mutations in a novel gene, UBIAD1, were recently found to cause the autosomal dominant eye disease Schnyder corneal dystrophy (SCD). SCD is characterized by an abnormal deposition of cholesterol and phospholipids in the cornea resulting in progressive corneal opacification and visual loss. We characterized lesions in the UBIAD1 gene in new SCD(More)
AIMS The Bowman-Birk inhibitor (BBI), is a serine protease inhibitor derived from soy beans, which is presently being evaluated in clinical trials for its ability to serve as a cancer preventive or anti-inflammatory agent. The form of BBI currently in clinical trials is known as Bowman-Birk inhibitor concentrate (BBIC). There have been anecdotal reports(More)
Castrate-Resistant Prostate Cancer (CRPC) is characterized by persistent androgen receptor-driven tumor growth in the apparent absence of systemic androgens. Current evidence suggests that CRPC cells can produce their own androgens from endogenous sterol precursors that act in an intracrine manner to stimulate tumor growth. The mechanisms by which CRPC(More)
OBJECTIVE We sought to analyze the prevalence and incremental burden of depression among elderly with prostate cancer. METHODS We adopted a retrospective cohort design using the Surveillance, Epidemiology and End Results-Medicare linked database between 1995 and 2003. Patients with prostate cancer diagnosed between 1995 and 1998 were identified and(More)
The mechanisms of mechanosensitivity underlying the response of the human bladder to stretch are poorly understood. Animal data suggest that stretch-activated two-pore-domain (K2P) K(+) channels play a critical role in bladder relaxation during the filling phase. The objective of this study was to characterize the expression and function of(More)
We report a cell line (hBSM) established from human urinary bladder wall smooth muscle that maintains most of the phenotypic characteristics of smooth muscle cells. Cells were dissociated from the muscular layer with collagenase (1 mg/ml) and collected and grown in M199 supplemented with 10% fetal calf serum and 1% antibiotic–antimycotic. Primary cultures(More)
