摘要:
A method of identifying an agent which modulates hydroxylation of hypoxia inducible factor (HIF), comprises contacting a HIF asparagine hydroxylase and a test substance in the presence of a substrate of the hydroxylase under conditions in which asparagine in the substrate is hydroxylated in the absence of the test substance; and determining hydroxylation of the substrate. Preferably the substrate is a HIF polypeptide comprising HIF-1α, a fragment thereof comprising Asn 803 of HIF-1α or a peptide analogue of HIF-1α or fragment thereof comprising an asparagine equivalent to Asn 803 of HIF-1α and wherein hydroxylation of Asn 803 or of a said equivalent asparagine is determined.

The invention provides a compound of one of the formulae (A), (B), (C), (D), (E), (F) as herein defined, or a salt thereof, for use in the treatment of a condition associated with increased or decreased HIF levels or activity, or a condition in which an increase or decrease in HIF levels or activity may be beneficial.
摘要:
A method of identifying, screening, characterising or designing a chemical entity, which mimics or binds to FIH, is described. The method comprises comparing a structural model of FIH with a structural model for said chemical entity, wherein said structural model of FIH is derived from structural factors or structural coordinates determined by subjecting to X-ray diffraction measurements a crystal comprising FIH. Such chemical entities may be used in the treatment of a condition associated with increased or decreased HIF levels or activity.

摘要:
The invention relates to the finding that the VHL tumour suppressor protein regulates hypoxia inducible factor α subunits, by targeting HIF α for destruction in normoxic, but not hypoxic cells. The invention provides assays for modulators of this interaction, and peptides based upon HIF α subunit sequences which may modulate this interaction.
摘要:
The MN/CA IX protein is identified herein as a hypoxia marker. The MN/CA9 gene promoter is characterized, and the location of the HIF-1 binding site within the MN/CA9 promoter is identified. Further, the hypoxia inducibility of the MN/CA9 gene and the uses of such inducibility are disclosed. In one aspect, the invention provides diagnostic/prognostic tools for determining the presence of hypoxia in a tissue in a vertebrate, preferably a human, and for measuring the relative degree of hypoxia in said vertebrate. In another aspect, the invention provides methods using tumor biopsies to predict the radioresistance of a preneoplastic/neoplastic tissue in a vertebrate subject, preferably a human patient, for diseases in which MN/CA IX levels can be used to indicate radiobiologically relevant tumor hypoxia. Such predictive methods can be used as an aid in patient therapy selection.

摘要:
A way for a consumer to display personalized information is provided as a display device for displaying the personalized information or other objects, and an attachment mechanism that attaches the display device to a vehicle by way of a base and that is also detachable from the base. The personalized information may be placed on or inside the display device for the consumer, or the consumer may place the personalized information on or inside the display device himself. The personalized information may represent military affiliation, authorization, or may be any other personalized image or text. The base may be affixed to the vehicle by way of a magnet or other mechanism. The display device may include a recess for holding a can or cup. The display device may be pivoted relative to the base so that the display device may be displayed perpendicular or parallel to a plane defined by the vehicle's wheels.
摘要:
The present invention provides methods for increasing endogenous globin expression in a subject, specifically γ-globin expression. The invention also provides compounds and medicaments for use in the methods. The methods are particularly useful for increasing fetal hemoglobin production in a subject, and can be used to treat various disorders, e.g., β thalassemia and sickle cell disease.
