    Description: Technological advances have made possible the development of high-resolution genetic linkage maps for the mouse. These maps in turn offer exciting prospects for understanding mammalian genome evolution through comparative mapping, for developing mouse models of human disease, and for identifying the function of all genes in the organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Copeland, N G -- Jenkins, N A -- Gilbert, D J -- Eppig, J T -- Maltais, L J -- Miller, J C -- Dietrich, W F -- Weaver, A -- Lincoln, S E -- Steen, R G -- HG00198/HG/NHGRI NIH HHS/ -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Oct 1;262(5130):57-66.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉ABL-Basic Research Program, National Cancer Institute-Frederick Cancer Research and Development Center, MD 21702.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8211130" target="_blank"〉PubMed〈/a〉

    Description: The ligand for CD40 (CD40L) is a membrane glycoprotein on activated T cells that induces B cell proliferation and immunoglobulin secretion. Abnormalities in the CD40L gene were associated with an X-linked immunodeficiency in humans [hyper-IgM (immunoglobulin M) syndrome]. This disease is characterized by elevated concentrations of serum IgM and decreased amounts of all other isotypes. CD40L complementary DNAs from three of four patients with this syndrome contained distinct point mutations. Recombinant expression of two of the mutant CD40L complementary DNAs resulted in proteins incapable of binding to CD40 and unable to induce proliferation or IgE secretion from normal B cells. Activated T cells from the four affected patients failed to express wild-type CD40L, although their B cells responded normally to wild-type CD40L. Thus, these CD40L defects lead to a T cell abnormality that results in the failure of patient B cells to undergo immunoglobulin class switching.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, R C -- Armitage, R J -- Conley, M E -- Rosenblatt, H -- Jenkins, N A -- Copeland, N G -- Bedell, M A -- Edelhoff, S -- Disteche, C M -- Simoneaux, D K -- A125129/PHS HHS/ -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Feb 12;259(5097):990-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7679801" target="_blank"〉PubMed〈/a〉

    Description: The cytoplasmic tyrosine kinase, Bruton's tyrosine kinase (Btk, formerly bpk or atk), is crucial for B cell development. Loss of kinase activity results in the human immunodeficiency, X-linked agammaglobulinemia, characterized by a failure to produce B cells. In the murine X-linked immunodeficiency (XID), B cells are present but respond abnormally to activating signals. The Btk gene, btk, was mapped to the xid region of the mouse X chromosome by interspecific backcross analysis. A single conserved residue within the amino terminal unique region of Btk was mutated in XID mice. This change in xid probably interferes with normal B cell signaling mediated by Btk protein interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rawlings, D J -- Saffran, D C -- Tsukada, S -- Largaespada, D A -- Grimaldi, J C -- Cohen, L -- Mohr, R N -- Bazan, J F -- Howard, M -- Copeland, N G -- AR36834/AR/NIAMS NIH HHS/ -- N01-CO-74101/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Jul 16;261(5119):358-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, University of California, Los Angeles 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8332901" target="_blank"〉PubMed〈/a〉

    Description: Human colorectal cancers (CRCs) display a large number of genetic and epigenetic alterations, some of which are causally involved in tumorigenesis (drivers) and others that have little functional impact (passengers). To help distinguish between these two classes of alterations, we used a transposon-based genetic screen in mice to identify candidate genes for CRC. Mice harboring mutagenic Sleeping Beauty (SB) transposons were crossed with mice expressing SB transposase in gastrointestinal tract epithelium. Most of the offspring developed intestinal lesions, including intraepithelial neoplasia, adenomas, and adenocarcinomas. Analysis of over 16,000 transposon insertions identified 77 candidate CRC genes, 60 of which are mutated and/or dysregulated in human CRC and thus are most likely to drive tumorigenesis. These genes include APC, PTEN, and SMAD4. The screen also identified 17 candidate genes that had not previously been implicated in CRC, including POLI, PTPRK, and RSPO2.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2743559/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2743559/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Starr, Timothy K -- Allaei, Raha -- Silverstein, Kevin A T -- Staggs, Rodney A -- Sarver, Aaron L -- Bergemann, Tracy L -- Gupta, Mihir -- O'Sullivan, M Gerard -- Matise, Ilze -- Dupuy, Adam J -- Collier, Lara S -- Powers, Scott -- Oberg, Ann L -- Asmann, Yan W -- Thibodeau, Stephen N -- Tessarollo, Lino -- Copeland, Neal G -- Jenkins, Nancy A -- Cormier, Robert T -- Largaespada, David A -- R01 CA113636/CA/NCI NIH HHS/ -- R01 CA113636-01A1/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1747-50. doi: 10.1126/science.1163040.
