    Description: CD9 is an integral membrane protein associated with integrins and other membrane proteins. Mice lacking CD9 were produced by homologous recombination. Both male and female CD9-/- mice were born healthy and grew normally. However, the litter size from CD9-/- females was less than 2% of that of the wild type. In vitro fertilization experiments indicated that the cause of this infertility was due to the failure of sperm-egg fusion. When sperm were injected into oocytes with assisted microfertilization techniques, however, the fertilized eggs developed to term. These results indicate that CD9 has a crucial role in sperm-egg fusion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyado, K -- Yamada, G -- Yamada, S -- Hasuwa, H -- Nakamura, Y -- Ryu, F -- Suzuki, K -- Kosai, K -- Inoue, K -- Ogura, A -- Okabe, M -- Mekada, E -- New York, N.Y. -- Science. 2000 Jan 14;287(5451):321-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Life Science, Kurume University, Kurume, Fukuoka 839-0861, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10634791" target="_blank"〉PubMed〈/a〉

    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〉

    Description: Previous studies have demonstrated that allelic deletions of the short arm of chromosome 17 occur in over 75% of colorectal carcinomas. Twenty chromosome 17p markers were used to localize the common region of deletion in these tumors to a region contained within bands 17p12 to 17p13.3. This region contains the gene for the transformation-associated protein p53. Southern and Northern blot hybridization experiments provided no evidence for gross alterations of the p53 gene or surrounding sequences. As a more rigorous test of the possibility that p53 was a target of the deletions, the p53 coding regions from two tumors were analyzed; these two tumors, like most colorectal carcinomas, had allelic deletions of chromosome 17p and expressed considerable amounts of p53 messenger RNA from the remaining allele. The remaining p53 allele was mutated in both tumors, with an alanine substituted for valine at codon 143 of one tumor and a histidine substituted for arginine at codon 175 of the second tumor. Both mutations occurred in a highly conserved region of the p53 gene that was previously found to be mutated in murine p53 oncogenes. The data suggest that p53 gene mutations may be involved in colorectal neoplasia, perhaps through inactivation of a tumor suppressor function of the wild-type p53 gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baker, S J -- Fearon, E R -- Nigro, J M -- Hamilton, S R -- Preisinger, A C -- Jessup, J M -- vanTuinen, P -- Ledbetter, D H -- Barker, D F -- Nakamura, Y -- White, R -- Vogelstein, B -- GM07184/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- HD20619/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Apr 14;244(4901):217-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oncology Center, Johns Hopkins University School of Medicine, Baltimore, MD 21231.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2649981" target="_blank"〉PubMed〈/a〉

    Description: DNA methylation of CpG dinucleotides is an important epigenetic modification of mammalian genomes and is essential for the regulation of chromatin structure, of gene expression and of genome stability. Differences in DNA methylation patterns underlie a wide range of biological processes, such as genomic imprinting, inactivation of the X chromosome, embryogenesis, and carcinogenesis. Inheritance of the epigenetic methylation pattern is mediated by the enzyme DNA methyltransferase 1 (Dnmt1), which methylates newly synthesized CpG sequences during DNA replication, depending on the methylation status of the template strands. The protein UHRF1 (also known as Np95 and ICBP90) recognizes hemi-methylation sites via a SET and RING-associated (SRA) domain and directs Dnmt1 to these sites. Here we report the crystal structures of the SRA domain in free and hemi-methylated DNA-bound states. The SRA domain folds into a globular structure with a basic concave surface formed by highly conserved residues. Binding of DNA to the concave surface causes a loop and an amino-terminal tail of the SRA domain to fold into DNA interfaces at the major and minor grooves of the methylation site. In contrast to fully methylated CpG sites recognized by the methyl-CpG-binding domain, the methylcytosine base at the hemi-methylated site is flipped out of the DNA helix in the SRA-DNA complex and fits tightly into a protein pocket on the concave surface. The complex structure suggests that the successive flip out of the pre-existing methylated cytosine and the target cytosine to be methylated is associated with the coordinated transfer of the hemi-methylated CpG site from UHRF1 to Dnmt1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arita, Kyohei -- Ariyoshi, Mariko -- Tochio, Hidehito -- Nakamura, Yusuke -- Shirakawa, Masahiro -- England -- Nature. 2008 Oct 9;455(7214):818-21. doi: 10.1038/nature07249.

    Description: Atopic dermatitis is a chronic inflammatory skin disease that affects 15-30% of children and approximately 5% of adults in industrialized countries. Although the pathogenesis of atopic dermatitis is not fully understood, the disease is mediated by an abnormal immunoglobulin-E immune response in the setting of skin barrier dysfunction. Mast cells contribute to immunoglobulin-E-mediated allergic disorders including atopic dermatitis. Upon activation, mast cells release their membrane-bound cytosolic granules leading to the release of several molecules that are important in the pathogenesis of atopic dermatitis and host defence. More than 90% of patients with atopic dermatitis are colonized with Staphylococcus aureus in the lesional skin whereas most healthy individuals do not harbour the pathogen. Several staphylococcal exotoxins can act as superantigens and/or antigens in models of atopic dermatitis. However, the role of these staphylococcal exotoxins in disease pathogenesis remains unclear. Here we report that culture supernatants of S. aureus contain potent mast-cell degranulation activity. Biochemical analysis identified delta-toxin as the mast cell degranulation-inducing factor produced by S. aureus. Mast cell degranulation induced by delta-toxin depended on phosphoinositide 3-kinase and calcium (Ca(2+)) influx; however, unlike that mediated by immunoglobulin-E crosslinking, it did not require the spleen tyrosine kinase. In addition, immunoglobulin-E enhanced delta-toxin-induced mast cell degranulation in the absence of antigen. Furthermore, S. aureus isolates recovered from patients with atopic dermatitis produced large amounts of delta-toxin. Skin colonization with S. aureus, but not a mutant deficient in delta-toxin, promoted immunoglobulin-E and interleukin-4 production, as well as inflammatory skin disease. Furthermore, enhancement of immunoglobulin-E production and dermatitis by delta-toxin was abrogated in Kit(W-sh/W-sh) mast-cell-deficient mice and restored by mast cell reconstitution. These studies identify delta-toxin as a potent inducer of mast cell degranulation and suggest a mechanistic link between S. aureus colonization and allergic skin disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4090780/" 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/PMC4090780/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakamura, Yuumi -- Oscherwitz, Jon -- Cease, Kemp B -- Chan, Susana M -- Munoz-Planillo, Raul -- Hasegawa, Mizuho -- Villaruz, Amer E -- Cheung, Gordon Y C -- McGavin, Martin J -- Travers, Jeffrey B -- Otto, Michael -- Inohara, Naohiro -- Nunez, Gabriel -- R01 AR059688/AR/NIAMS NIH HHS/ -- R01AR059688/AR/NIAMS NIH HHS/ -- R01HL062996/HL/NHLBI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2013 Nov 21;503(7476):397-401. doi: 10.1038/nature12655.

    Description: Regulated transcription controls the diversity, developmental pathways and spatial organization of the hundreds of cell types that make up a mammal. Using single-molecule cDNA sequencing, we mapped transcription start sites (TSSs) and their usage in human and mouse primary cells, cell lines and tissues to produce a comprehensive overview of mammalian gene expression across the human body. We find that few genes are truly 'housekeeping', whereas many mammalian promoters are composite entities composed of several closely separated TSSs, with independent cell-type-specific expression profiles. TSSs specific to different cell types evolve at different rates, whereas promoters of broadly expressed genes are the most conserved. Promoter-based expression analysis reveals key transcription factors defining cell states and links them to binding-site motifs. The functions of identified novel transcripts can be predicted by coexpression and sample ontology enrichment analyses. The functional annotation of the mammalian genome 5 (FANTOM5) project provides comprehensive expression profiles and functional annotation of mammalian cell-type-specific transcriptomes with wide applications in biomedical research.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4529748/" target="_blank"〉〈img

    Description: The interleukin-2 (IL-2) receptor gamma chain (IL-2R gamma) is an essential component of high- and intermediate-affinity IL-2 receptors. IL-2R gamma was demonstrated to be a component of the IL-4 receptor on the basis of chemical cross-linking data, the ability of IL-2R gamma to augment IL-4 binding affinity, and the requirement for IL-2R gamma in IL-4-mediated phosphorylation of insulin receptor substrate-1. The observation that IL-2R gamma is a functional component of the IL-4 receptor, together with the finding that IL-2R gamma associates with the IL-7 receptor, begins to elucidate why deficiency of this common gamma chain (gamma c) has a profound effect on lymphoid function and development, as seen in X-linked severe combined immunodeficiency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Russell, S M -- Keegan, A D -- Harada, N -- Nakamura, Y -- Noguchi, M -- Leland, P -- Friedmann, M C -- Miyajima, A -- Puri, R K -- Paul, W E -- New York, N.Y. -- Science. 1993 Dec 17;262(5141):1880-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Pulmonary and Molecular Immunology, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8266078" target="_blank"〉PubMed〈/a〉

    Description: The interleukin-2 receptor gamma chain (IL-2R gamma) is a necessary component of functional IL-2 receptors. IL-2R gamma mutations result in X-linked severe combined immunodeficiency (XSCID) in humans, a disease characterized by the presence of few or no T cells. In contrast, SCID patients with IL-2 deficiency and IL-2-deficient mice have normal numbers of T cells, suggesting that IL-2R gamma is part of more than one cytokine receptor. By using chemical cross-linking, IL-2R gamma was shown to be physically associated with the IL-7 receptor. The presence of IL-2R gamma augmented both IL-7 binding affinity and the efficiency of internalization of IL-7. These findings may help explain the defects of XSCID. Given its role in more than one cytokine receptor system, the common gamma chain (gamma c) is proposed as the designation for IL-2R gamma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noguchi, M -- Nakamura, Y -- Russell, S M -- Ziegler, S F -- Tsang, M -- Cao, X -- Leonard, W J -- New York, N.Y. -- Science. 1993 Dec 17;262(5141):1877-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Pulmonary and Molecular Immunology, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8266077" target="_blank"〉PubMed〈/a〉

    Description: A fundamental problem in the identification and isolation of tumor suppressor and other growth-inhibiting genes is the loss of power of genetic complementation at the subchromosomal level. A direct genetic strategy was developed to isolate subchromosomal transferable fragments (STFs) from any chromosome, each containing a selectable marker within the human DNA, that could be transferred to any mammalian cell. As a test of the method, several overlapping STFs from 11p15 were shown to cause in vitro growth arrest of rhabdomyosarcoma cells. This activity mapped between the beta-globin and insulin genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koi, M -- Johnson, L A -- Kalikin, L M -- Little, P F -- Nakamura, Y -- Feinberg, A P -- CA54358/CA/NCI NIH HHS/ -- T32GM07314/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 16;260(5106):361-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Internal Medicine, University of Michigan Medical School, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8469989" target="_blank"〉PubMed〈/a〉

    Description: Genes encoding human beta-type globin undergo a developmental switch from embryonic to fetal to adult-type expression. Mutations in the adult form cause inherited hemoglobinopathies or globin disorders, including sickle cell disease and thalassemia. Some experimental results have suggested that these diseases could be treated by induction of fetal-type hemoglobin (HbF). However, the mechanisms that repress HbF in adults remain unclear. We found that the LRF/ZBTB7A transcription factor occupies fetal gamma-globin genes and maintains the nucleosome density necessary for gamma-globin gene silencing in adults, and that LRF confers its repressive activity through a NuRD repressor complex independent of the fetal globin repressor BCL11A. Our study may provide additional opportunities for therapeutic targeting in the treatment of hemoglobinopathies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4778394/" 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/PMC4778394/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masuda, Takeshi -- Wang, Xin -- Maeda, Manami -- Canver, Matthew C -- Sher, Falak -- Funnell, Alister P W -- Fisher, Chris -- Suciu, Maria -- Martyn, Gabriella E -- Norton, Laura J -- Zhu, Catherine -- Kurita, Ryo -- Nakamura, Yukio -- Xu, Jian -- Higgs, Douglas R -- Crossley, Merlin -- Bauer, Daniel E -- Orkin, Stuart H -- Kharchenko, Peter V -- Maeda, Takahiro -- R01 AI084905/AI/NIAID NIH HHS/ -- R01 HL032259/HL/NHLBI NIH HHS/ -- R56 DK105001/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 15;351(6270):285-9. doi: 10.1126/science.aad3312.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA. ; Department of Biomedical Informatics, Harvard Medical School, Boston, MA 02115, USA. ; Division of Hematology/Oncology, Boston Children's Hospital, Department of Pediatric Oncology, Dana-Farber Cancer Institute, Harvard Stem Cell Institute, Department of Pediatrics, Harvard Medical School, Boston, MA 02115, USA. ; School of Biotechnology and Biomolecular Sciences, University of New South Wales, Sydney, NSW 2052, Australia. ; Medical Research Council, Molecular Haematology Unit, Weatherall Institute of Molecular Medicine, Oxford University, Oxford, UK. ; Cell Engineering Division, RIKEN BioResource Center, Tsukuba, Ibaraki, Japan. ; Cell Engineering Division, RIKEN BioResource Center, Tsukuba, Ibaraki, Japan.
