Peptide hormones are post-translationally matured before they reach a structure in which they can fulfill their biological functions. The prohormone processing may encompass a variety of endoproteolytic cleavages, N- and C-terminal trimmings, and amino acid derivatizations. The same prohormone can be variably processed in different cell types and, in(More)
Measurement of cardiac natriuretic peptides in plasma has gained a diagnostic role in the assessment of heart failure. Plasma measurement is though hampered by the marked instability of the hormones, which has led to the development of analyses that target N-terminal fragments from the prohormone. These fragments are stable in plasma and represent surrogate(More)
Objective Primary androgen deprivation therapy (ADT) remains the gold standard in the management of patients with advanced prostate cancer (PCa). ADT relieves symptoms and reduces tumor burden, but it has never been demonstrated to increase either PCa-specific or overall survival per se. Several trials have challenged this dogma. The aim of this study was(More)
C-type natriuretic peptide (CNP) is expressed in several human tissues. We designed a specific processing-independent assay for proCNP-derived products and quantitated the concentrations in human seminal plasma from normal and vasectomized men. Antibodies were raised against the N-terminus of human proCNP 11-27. Samples were incubated with trypsin prior to(More)
AIM Urokinase plasminogen activator receptor (uPAR) plays a central role during cancer invasion by facilitating pericellular proteolysis. We initiated the prospective 'Copenhagen uPAR Prostate Cancer' study to investigate the significance of uPAR levels in prostate cancer (PCa) patients. METHODS Plasma samples and clinical data from patients with newly(More)
AIM Seminal plasma offer a more organ-specific matrix for markers in prostatic disease. We hypothesized that C-type natriuretic peptide (CNP) expression may constitute such a new target. METHODS Patients with benign prostatic hyperplasia, clinically localized and metastatic prostate cancer were examined for CNP and CNP precursor (proCNP) concentrations in(More)
AIMS Lymph node metastasis (N1) is an adverse prognostic factor for men with clinically localised prostate cancer (PCa), but the prediction of N1 disease remains difficult. Urokinase plasminogen activator receptor (uPAR) plays an important role in angiogenesis and tumorigenesis. We analysed whether plasma levels of the soluble uPAR forms uPAR(I-III),(More)
The natriuretic peptide system comprises three structurally related peptides: atrial natriuretic peptide, B-type natriuretic peptide and C-type natriuretic peptide. In circulation, they play an important endocrine role in the regulation of cardiovascular homeostasis by maintaining blood pressure and extracellular fluid volume. Atrial natriuretic peptide and(More)
