  • Publication number: 20070218055
    Abstract: Positional cloning has been carried out to identify the gene responsible for the hypochromic anemia of the zebrafish mutant weissherbst. The gene, ferroportin1, encodes a novel multiple-transmembrane domain protein, expressed in the yolk sac. Zebrafish ferroportin1 is required for the transport of iron from maternally-derived yolk stores to the circulation, and functions as an iron exporter when expressed in Xenopus oocytes. Human and mouse homologs of the ferroportin1 gene have been identified. The invention includes isolated polynucleotides, vectors and host cells comprising nucleotide sequences encoding Ferroportin1 proteins and variants thereof, including those having iron transport function. The invention also includes polypeptides encoded by ferroportin1 genes and variants of such polypeptides, and fusion polypeptides comprising a Ferroportin1 or a portion thereof.

  • Publication number: 20050221487
    Abstract: The present invention provides a method for enhancing the proliferation and/or hematopoietic differentiation and/or maintenance of mammalian stem cells. The method is useful for generating expanded populations of hematopoietic stem cells (HSCs) and thus mature blood cell lineages. This is desirable where a mammal has suffered a decrease in hematopoietic or mature blood cells as a consequence of disease, radiation or chemotherapy. The method of the present invention comprises increasing the intracellular level of a cdx in stem cells, including hematopoietic stem cells, in culture, either by providing an exogenous cdx protein to the cell, or by introduction into the cell of a genetic construct encoding a cdx. The cdx is selected from the cdx family and includes cdx1, cdx2, or cdx4. The cdx may be a wild type protein appropriate for the species from which the cells are derived, or a mutant form of the protein.

  • Publication number: 20050155087
    Abstract: The present invention is directed to a novel, target-blind approach to drug discovery. The concept is to model human phenotypes in a teleost, such as a zebrafish, and then screen compounds, e.g., small molecules, for their ability to alter the phenotype. Because the screen is performed with a whole vertebrate organism and uses a phenotype as the output, the need to first identify target genes is eliminated. This approach is powerful because a single screen can theoretically detect drugs affecting any target relevant to the phenotype being observed, even if those targets are not yet characterized.

  • Patent number: 5700927
    Abstract: Disclosed is a substantially pure DNA encoding a Tbc1 polypeptide; a substantially pure Tbc1 polypeptide; and methods of using such DNA to express Tbc1 in leukemic stem cells and treat certain leukemias. Also disclosed are methods for diagnosing other leukemias and spermatogenesis disorders by assaying for Tbc1 expression.
