    Negative regulation of Wingless signaling by D-axin, a Drosophila homolog of axin (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-03-12
    Description: Wnt/Wingless directs many cell fates during development. Wnt/Wingless signaling increases the amount of beta-catenin/Armadillo, which in turn activates gene transcription. Here the Drosophila protein D-Axin was shown to interact with Armadillo and D-APC. Mutation of d-axin resulted in the accumulation of cytoplasmic Armadillo and one of the Wingless target gene products, Distal-less. Ectopic expression of d-axin inhibited Wingless signaling. Hence, D-Axin negatively regulates Wingless signaling by down-regulating the level of Armadillo. These results establish the importance of the Axin family of proteins in Wnt/Wingless signaling in Drosophila.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hamada, F -- Tomoyasu, Y -- Takatsu, Y -- Nakamura, M -- Nagai, S -- Suzuki, A -- Fujita, F -- Shibuya, H -- Toyoshima, K -- Ueno, N -- Akiyama, T -- New York, N.Y. -- Science. 1999 Mar 12;283(5408):1739-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncogene Research, Research Institute for Microbial Diseases, Osaka University, 3-1 Yamadaoka, Suita 565-0871, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10073940" target="_blank"〉PubMed〈/a〉

    Rapid colorectal adenoma formation initiated by conditional targeting of the Apc gene (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-10-06
    Description: Familial adenomatous polyposis coli (FAP) is a disease characterized by the development of multiple colorectal adenomas, and affected individuals carry germline mutations in the APC gene. With the use of a conditional gene targeting system, a mouse model of FAP was created that circumvents the embryonic lethality of Apc deficiency and directs Apc inactivation specifically to the colorectal epithelium. loxP sites were inserted into the introns around Apc exon 14, and the resultant mutant allele (Apc580S) was introduced into the mouse germline. Mice homozygous for Apc580S were normal; however, upon infection of the colorectal region with an adenovirus encoding the Cre recombinase, the mice developed adenomas within 4 weeks. The adenomas showed deletion of Apc exon 14, indicating that the loss of Apc function was caused by Cre-loxP-mediated recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, H -- Toyama, K -- Shioya, H -- Ito, M -- Hirota, M -- Hasegawa, S -- Matsumoto, H -- Takano, H -- Akiyama, T -- Toyoshima, K -- Kanamaru, R -- Kanegae, Y -- Saito, I -- Nakamura, Y -- Shiba, K -- Noda, T -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):120-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Cancer Institute, Toshima-ku, Tokyo 170, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311916" target="_blank"〉PubMed〈/a〉

    Association of B cell antigen receptor with protein tyrosine kinase Lyn (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-01-11
    Description: Antigen is thought to cross-link membrane-bound immunoglobulins (Igs) of B cells, causing proliferation and differentiation or the inhibition of growth. Protein tyrosine kinases are probably involved in signal transduction for cell proliferation and differentiation. The Src-like protein tyrosine kinase Lyn is expressed preferentially in B cells. The Lyn protein and its kinase activity could be coimmunoprecipitated with IgM from detergent lysates. Cross-linking of membrane-bound IgM induced a rapid increase in tyrosine phosphorylation of at least ten distinct proteins of B cells. Thus, Lyn is physically associated with membrane-bound IgM, and is suggested to participate in antigen-mediated signal transduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamanashi, Y -- Kakiuchi, T -- Mizuguchi, J -- Yamamoto, T -- Toyoshima, K -- New York, N.Y. -- Science. 1991 Jan 11;251(4990):192-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, University of Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1702903" target="_blank"〉PubMed〈/a〉

    Binding of APC to the human homolog of the Drosophila discs large tumor suppressor protein (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-05-17
    Description: The adenomatous polyposis coli gene (APC) is mutated in familial adenomatous polyposis and in sporadic colorectal tumors, and its product binds to the adherens junction protein beta-catenin. Overexpression of APC blocks cell cycle progression. The APC-beta-catenin complex was shown to bind to DLG, the human homolog of the Drosophila discs large tumor suppressor protein. This interaction required the carboxyl-terminal region of APC and the DLG homology repeat region of DLG. APC colocalized with DLG at the lateral cytoplasm in rat colon epithelial cells and at the synapse in cultured hippocampal neurons. These results suggest that the APC-DLG complex may participate in regulation of both cell cycle progression and neuronal function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsumine, A -- Ogai, A -- Senda, T -- Okumura, N -- Satoh, K -- Baeg, G H -- Kawahara, T -- Kobayashi, S -- Okada, M -- Toyoshima, K -- Akiyama, T -- New York, N.Y. -- Science. 1996 May 17;272(5264):1020-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncogene Research, Institute for Microbial Diseases, Osaka University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8638125" target="_blank"〉PubMed〈/a〉

    Amplification and enhanced expression of the epidermal growth factor receptor gene in A431 human carcinoma cells (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-04-27
    Description: The sequence of the human epidermal growth factor (EGF) receptor shows great homology with the avian erythroblastosis virus v-erb B oncogene, raising the possibility that the receptor gene is identical to the c-erb B protooncogene. Human A431 epidermoid carcinoma cells, which have an unusually high number of EGF receptors, were examined to determine whether elevated EGF receptor levels correlate with gene amplification. Southern blots of genomic DNA's from A431 and other human cell lines were probed with either a v-erb B gene fragment or a human EGF receptor complementary DNA clone (pE7), previously isolated from an A431 complementary DNA library. When either probe was used to analyze Eco RI- or Hind III-generated DNA fragments, EGF receptor DNA sequences were amplified about 30-fold in A431. Differences in the banding pattern of A431 DNA fragments relative to normal fibroblast DNA indicate the occurrence of a rearrangement in the region of the receptor gene. Furthermore, A431 cells contain a characteristic, prominent 2.9-kilobase RNA. These results are consistent with the hypothesis that, in A431 cells, gene amplification, possibly associated with a translocation event, may result in the overproduction of EGF receptor protein or the appearance of the transformed phenotype (or both).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merlino, G T -- Xu, Y H -- Ishii, S -- Clark, A J -- Semba, K -- Toyoshima, K -- Yamamoto, T -- Pastan, I -- New York, N.Y. -- Science. 1984 Apr 27;224(4647):417-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200934" target="_blank"〉PubMed〈/a〉

    The product of the human c-erbB-2 gene: a 185-kilodalton glycoprotein with tyrosine kinase activity (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-06-27
    Description: Antibodies were raised against a synthetic peptide corresponding to 14 amino acid residues at the COOH-terminus of a protein deduced from the human c-erbB-2 nucleotide sequence. These antibodies immunoprecipitated a 185-kilodalton glycoprotein from MKN-7 adenocarcinoma cells. Incubation of the immunoprecipitates with (gamma-32P)ATP resulted in the phosphorylation of this protein on tyrosine residues. These results indicate that the human c-erbB-2 gene product is the 185-kilodalton glycoprotein that is associated with tyrosine kinase activity. Although the c-erbB-2 protein was predicted to encode a protein very similar to epidermal growth factor (EGF) receptor, EGF did not stimulate this kinase activity either in vivo or in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akiyama, T -- Sudo, C -- Ogawara, H -- Toyoshima, K -- Yamamoto, T -- New York, N.Y. -- Science. 1986 Jun 27;232(4758):1644-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3012781" target="_blank"〉PubMed〈/a〉
