  • Patent number: 8796505
    Abstract: A method for the preparation of a eukaryotic organism, for example selected from plants, animals and fungi, showing constitutive, inducible and/or organ specific expression of a specifically modified TPS gene, which comprises the steps of providing a TPS gene; designing a suitable modification to the TPS gene by aligning the gene with the corresponding gene of yeast and establishing which part of the gene extends beyond the 5? terminus of the yeast gene; deleting or inactivating a part of the N-terminal region of the TPS gene extending beyond the 5? terminus of the yeast gene, in order to achieve an increased trehalose-6-phosphate synthase activity; cloning the thus modified gene into an expression vector under the control of a constitutive, inducible and/or organ-specific promoter; transforming a plant cell or tissue with the thus obtained expression vector; and regenerating a complete plant from the transformed plant cell or tissue.

  • Publication number: 20130177565
    Abstract: The present invention relates to the field of pathological angiogenesis and arteriogenesis and, in particular, to a stress-induced phenotype in a transgenic mouse (PIGF?/?) that does not produce Placental Growth Factor (PIGF) and that demonstrates an impaired vascular endothelial growth factor (VEGF)-dependent response. PIGF deficiency has a negative influence on diverse pathological processes of angiogenesis, arteriogenesis and vascular leakage comprising ischemic retinopathy, tumor formation, pulmonary hypertension, vascular leakage (edema formation) and inflammatory disorders. The invention thus relates to molecules that can inhibit the binding of PIGF to its receptor (VEGFR-1), such as monocloncal antibodies and tetrameric peptides, and to the use of these molecules to treat the above-mentioned pathological processes.

  • Patent number: 8048986
    Abstract: The invention relates to a recombinant receptor, comprising a ligand-binding domain and a signaling domain that comprises a heterologous bait polypeptide, which receptor is inactivated by binding of a prey polypeptide to the heterologous bait peptide, either in presence or absence of a ligand binding to the ligand-binding domain. The receptor is activated by addition of a compound that disrupts the bait-prey interaction. The invention also relates to a method of screening compounds that disrupt compound-compound binding using the recombinant receptor.

  • Patent number: 8003096
    Abstract: Described are methods of modulating stem/progenitor cell recruitment involving molecules that agonize the formation of plasmin stimulating the recruitment of stem/progenitor cells, including hematopoietic and endothelial precursor cells. Conversely, antagonists of plasmin can inhibit recruitment of the stem cells. In addition, the identification of the uPA receptor (uPAR) as a retention signal for stem cells in their niche suggests a novel method for increased engraftment and isolation of multipotent stem cells.

  • Patent number: 7888322
    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.

  • Patent number: 7863246
    Abstract: The present invention relates to the treatment of motoneuron diseases. More particularly, the invention relates to the treatment of amyotrophic lateral sclerosis (ALS). It is found that the intracerebroventricular delivery of low amounts of vascular endothelial growth factor into a pre-clinical ALS animal model induces a significant motor performance and prolongation of survival time of the animals.

  • Patent number: 7807809
    Abstract: Methods for determining whether a tissue sample or an analogue and/or derivative thereof comprises a cell with a chromosome (11:18) translocation associated with malignancies such as mucosa-associated lymphoid tissue (MALT) lymphomas. The invention further provides insight into a novel mechanism of transformation of primary cells. The mechanism involves expression of a fusion proteinaceous molecule comprising at least apoptosis inhibitor 2 (API2) or a functional part, derivative and/or analogue thereof fused to at least one other proteinaceous molecule. The invention also provides a novel nucleic acid sequence and proteinaceous molecule expressed from the sequence termed “MALT-lymphoma associated Translocation (MLT) protein.
