  • Patent number: 7357929
    Abstract: This invention relates to antagonists of placental growth factor and signalling thereof, pharmaceutical compositions containing such antagonists and the use of such antagonists to prevent bone loss or bone mass and to enhance bone healing including the treatment of conditions which present with low bone mass and/or bone defects in vertebrates, and particularly mammals, including humans.

  • Patent number: 7341992
    Abstract: The in vivo role of the N-terminal lectin-like domain of thrombomodulin was studied by using homologous recombination in murine ES cells to create mutant mice that lack this region of thrombomodulin. Phenotypic analysis shows that said mice respond identically to their wild type littermates following pro-coagulant challenges meaning that the protein C pathway is not altered by the mutation. However, following several inflammatory stimuli, it was observed that the mutant mice showed an elevated neutrophil extravasation in several organs. It is found that leukocyte adhesion could be abrogated by addition of recombinant lectin-domain meaning that said domain has direct anti-inflammatory properties which means that the lectin-like domain can be used to manufacture a medicament useful for the treatment of a variety of inflammatory disease processes.

  • Publication number: 20080032314
    Abstract: The present invention relates to neurological and physiological dysfunction associated with neuron disorders. In particular, the invention relates to the involvement of vascular endothelial growth factor (VEGF) and homologues in the aetiology of motor neuron disorders. The invention further concerns a novel, mutant transgenic mouse (VEGFm/m) with a homozygous deletion in the hypoxia responsive element (HRE) of the VEGF promoter which alters the hypoxic upregulation of VEGF. These mice suffer severe adult onset muscle weakness due to progressive spinal motor neuron degeneration which is reminiscent of amyotrophic lateral sclerosis (ALS)—a fatal disorder with unknown aetiology. Furthermore, the neuropathy of these mice is not caused by vascular defects, but is due to defective VEGF-mediated survival signals to motor neurons.

  • Publication number: 20070190586
    Abstract: A method having clinically sufficient degree of diagnostic accuracy for detecting the presence of coronary artery disease in a human patient from the general population and for distinguishing between the stages of the disease in that patient is disclosed. The stages are, first, the non-acute stage, which is either asymptomatic coronary artery disease or stable angina, second, the acute stage known as unstable angina, and, third, the acute stage known as acute myocardial infarction. The diseased state (as opposed to the non-diseased state) is indicated by the clinically significant presence of a first marker in a sample from the patient. The presence of one of the two acute stages, unstable angina or acute myocardial infarction, is indicated by the clinically significant presence of a second marker in a sample from the patient. The presence of the more severe acute stage known as acute myocardial infarction is indicated by the clinically significant presence of a third marker in a sample from the patient.

  • Publication number: 20070172423
    Abstract: A method for modulating vasculogenesis or arteriogenesis or angiogenesis, especially for treating heart and limb ischemia, using the core domain protein of PDGF-C, a new member of the PDGF/VEGF family of growth factors, or a homodimer or a heterodimer comprising the core domain. Also disclosed are pharmaceutical compositions comprising the core protein, nucleotide sequences encoding the protein, and uses thereof in medical and diagnostic applications.

  • Publication number: 20050163781
    Abstract: The present invention is concerned with compositions for use in the medical art. More particularly the invention relates to uses of inhibitors against hypoxia-induced genes for the manufacture of a medicament to prevent and/or to suppress post-operative/post-wounding adhesions formation. Post-operative adhesions are an unwanted result from surgery and are a major source of postoperative morbidity and mortality. The invention applies to human and veterinary applications. To date, no single therapeutic approach has proven universally effective in preventing formation of post-operative adhesions formations.

  • Publication number: 20050136045
    Abstract: Methods for the identification, production and use of staphylokinase derivatives characterized by a reduced immunogenicity after administration in patients and that can be administered by a single bolus injection. The derivatives of the invention are obtained by preparing a DNA fragment comprising at least part of the coding sequence of staphylokinase; performing in vitro site-directed mutagenesis on the DNA fragment; cloning the mutated DNA fragment in a suitable vector; transforming a suitable host cell with the vector; culturing the host cell under conditions suitable for expressing the DNA fragment; purifying the staphylokinase derivative and chemically modifying Cys residues with thiol-directed polyethylene glycol. The invention also relates to pharmaceutical compositions comprising at least one of the staphylokinase derivatives according to the invention together with a suitable excipient, for treatment of arterial thrombosis.
