摘要:
A method of selecting a substance capable of controlling the activation of prorenin with the use of, as an indication, the ability to control the activation of prorenin by an interaction between proteins in the profragment domain of prorenin; a prorenin activation controlling substance which has a function of controlling the activation of prorenin based on the interaction between proteins in the profragment domain of prorenin; and hypotensors, organ overgrowth inhibitors and arterial thickening inhibitors containing the above-described prorenin activation controlling substance as the active ingredient.
摘要:
Disclosed is a novel renin-active substance by utilizing a anti-peptide antibody capable of specifically recognizing a specific amino acid sequence in the human prorenin profragment exemplified, as a typical example, by a complex formed from human prorenin and an anti-peptide antibody capable of specifically recognizing an amino acid sequence consisting of at least 15 amino acid residues located within an amino acid sequence consisting of 33 amino acid residues between the isoleucine residue at the 11th site and the arginine residue at the 43rd site within human prorenin profragment having an amino acid sequence consisting of 43 amino acid residues.

Die Erfindung betrifft transgene Ratten, in deren Genom mindestens ein menschliches Gen, dessen Genprodukt an der Blutdruckregulation beteiligt ist, integriert ist. Die Erfindung betrifft ferner transgene Ratten und deren Nachkommen, die einen erhöhten Blutdruck (>90/>140 mm Hg) oder Bluthochdruck (>95/>160 mm Hg) aufweisen. Schließlich betrifft die Erfindung Verfahren zur Herstellung der erfindungsgemäßen transgenen Ratten sowie deren Nachkommen und deren Verwendung für pharmakologische Untersuchungen.
摘要:
An expression system for recombinant production of a desired protein comprises CHO cells transformed with a DNA sequence having the desired protein coding sequence under control of the human metallothionein-II promoter. The cells can be maintained on serum-free medium and induced in the presence of an induction mediator. In addition, the system may include an enhancer element and/or a resistance-conferring gene to provide increased levels of expression. The system can process genomic as well as intronless DNA, and is capable of producing proteins which have the same characteristics as those obtained from native sources. Human growth hormone which is indistinguishable from that produced by the pituitary has been thus produced. Expression systems containing genes encoding alveolar surfactant protein (ASH), apolipoproteins AI and AII (apoAI and apoAII), atrial natriuretic factor (ANF), erythropoetin (Epo), and renin are also contemplated.

摘要:
Expression vectors and methods for effecting the production of recombinant renin, prorenin, and preprorenin are disclosed. Sufficient quantities are thus obtained to generate pharmaceuticals useful in the treatment of disorders mediated by excessive renin levels such as hypertension. Methods to purify renin and prorenin from cell supernatants and to increase mature renin secretion are also disclosed.
摘要:
There are provided a method for selection of a substance which is capable of controlling activation of prorenin where an adjusting ability of the activation of prorenin by protein-protein interaction in a profragment region of prorenin as indicator is used; a prorenin activation controlling substance having a function of controlling the activation of prorenin based on protein-protein interaction by a profragment region of prorenin; and hypotensor, organ hypertrophy suppressor and arterial thickening suppressor containing the said prorenin activation controlling substance as an effective ingredient.
摘要:
The present invention provides methods for assessing cardiovascular status in an individual, which comprise determining the sequence at one or more polymorphic positions within the human genes encoding ACE, AT1, AGT, renin, aldosterone synthase, type-2 angiotensin II receptor, endothelin receptor, and β-adrenoceptor. The invention also provides isolated nucleic acids encoding polymorphisms in genes encoding ACE, AT1, AGT, renin, aldosterone synthase, type-2 angiotensin II receptor, endothelin receptor and β-adrenoceptor, nucleic acid probes that hybridized to polymorphic positions, kits for the prediction of cardiovascular status, and nucleic acid and peptide targets for use in identifying candidate cardiovascular drugs.
