    Beschreibung: Mutations in MeCP2, which encodes a protein that has been proposed to function as a global transcriptional repressor, are the cause of Rett syndrome (RT T), an X-linked progressive neurological disorder. Although the selective inactivation of MeCP2 in neurons is sufficient to confer a Rett-like phenotype in mice, the specific functions of MeCP2 in postmitotic neurons are not known. We find that MeCP2 binds selectively to BDNF promoter III and functions to repress expression of the BDNF gene. Membrane depolarization triggers the calcium-dependent phosphorylation and release of MeCP2 from BDNF promoter III, thereby facilitating transcription. These studies indicate that MeCP2 plays a key role in the control of neuronal activity-dependent gene regulation and suggest that the deregulation of this process may underlie the pathology of RT T.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Wen G -- Chang, Qiang -- Lin, Yingxi -- Meissner, Alexander -- West, Anne E -- Griffith, Eric C -- Jaenisch, Rudolf -- Greenberg, Michael E -- HD 18655/HD/NICHD NIH HHS/ -- NS28829/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):885-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593183" target="_blank"〉PubMed〈/a〉

    Beschreibung: Steroid receptors bind to site-specific response elements in chromatin and modulate gene expression in a hormone-dependent fashion. With the use of a tandem array of mouse mammary tumor virus reporter elements and a form of glucocorticoid receptor labeled with green fluorescent protein, targeting of the receptor to response elements in live mouse cells was observed. Photobleaching experiments provide direct evidence that the hormone-occupied receptor undergoes rapid exchange between chromatin and the nucleoplasmic compartment. Thus, the interaction of regulatory proteins with target sites in chromatin is a more dynamic process than previously believed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNally, J G -- Muller, W G -- Walker, D -- Wolford, R -- Hager, G L -- New York, N.Y. -- Science. 2000 Feb 18;287(5456):1262-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Receptor Biology and Gene Expression, Building 41, Room B602, National Cancer Institute, Bethesda, MD 20892-5055, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10678832" target="_blank"〉PubMed〈/a〉

    Beschreibung: Basement membranes can help determine pathways of migrating axons. Although members of the nidogen (entactin) protein family are structural components of basement membranes, we find that nidogen is not required for basement membrane assembly in the nematode Caenorhabditis elegans. Nidogen is localized to body wall basement membranes and is required to direct longitudinal nerves dorsoventrally and to direct axons at the midlines. By examining migration of a single axon in vivo, we show that nidogen is required for the axon to switch from circumferential to longitudinal migration. Specialized basement membranes may thus regulate nerve position.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, S -- Wadsworth, W G -- New York, N.Y. -- Science. 2000 Apr 7;288(5463):150-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Robert Wood Johnson Medical School, Piscataway, NJ 08854-5635, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10753123" target="_blank"〉PubMed〈/a〉

    Beschreibung: HIF (hypoxia-inducible factor) is a transcription factor that plays a pivotal role in cellular adaptation to changes in oxygen availability. In the presence of oxygen, HIF is targeted for destruction by an E3 ubiquitin ligase containing the von Hippel-Lindau tumor suppressor protein (pVHL). We found that human pVHL binds to a short HIF-derived peptide when a conserved proline residue at the core of this peptide is hydroxylated. Because proline hydroxylation requires molecular oxygen and Fe(2+), this protein modification may play a key role in mammalian oxygen sensing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ivan, M -- Kondo, K -- Yang, H -- Kim, W -- Valiando, J -- Ohh, M -- Salic, A -- Asara, J M -- Lane, W S -- Kaelin , W G Jr -- New York, N.Y. -- Science. 2001 Apr 20;292(5516):464-8.

    Beschreibung: Schizophrenia is a complex disorder, and there is substantial evidence supporting a genetic etiology. Despite this, prior attempts to localize susceptibility loci have produced predominantly suggestive findings. A genome-wide scan for schizophrenia susceptibility loci in 22 extended families with high rates of schizophrenia provided highly significant evidence of linkage to chromosome 1 (1q21-q22), with a maximum heterogeneity logarithm of the likelihood of linkage (lod) score of 6.50. This linkage result should provide sufficient power to allow the positional cloning of the underlying susceptibility gene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3787922/" 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/PMC3787922/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brzustowicz, L M -- Hodgkinson, K A -- Chow, E W -- Honer, W G -- Bassett, A S -- 53216/Canadian Institutes of Health Research/Canada -- K08 MH01392/MH/NIMH NIH HHS/ -- N01-HG-65403/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2000 Apr 28;288(5466):678-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular and Behavioral Neuroscience, Rutgers University, Newark, NJ 07102, USA. brzustowicz@axon.rutgers.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10784452" target="_blank"〉PubMed〈/a〉

    Beschreibung: Natural killer cell (NK) receptors for major histocompatibility complex (MHC) class I influence engraftment and graft-versus-tumor effects after allogeneic bone marrow transplantation. We find that SH2-containing inositol phosphatase (SHIP) influences the repertoire of NK receptors. In adult SHIP-/- mice, the NK compartment is dominated by cells that express two inhibitory receptors capable of binding either self or allogeneic MHC ligands. This promiscuous repertoire has significant functional consequences, because SHIP-/- mice fail to reject fully mismatched allogeneic marrow grafts and show enhanced survival after such transplants. Thus, SHIP plays an important role in two processes that limit the success of allogeneic marrow transplantation: graft rejection and graft-versus-host disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Jia-Wang -- Howson, Julie M -- Ghansah, Tomar -- Desponts, Caroline -- Ninos, John M -- May, Sarah L -- Nguyen, Kim H T -- Toyama-Sorimachi, Noriko -- Kerr, William G -- P01 NS27405/NS/NINDS NIH HHS/ -- R01 DK54767/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 15;295(5562):2094-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immunology Program, H.

    Beschreibung: Specific short oligonucleotide sequences that enhance pre-mRNA splicing when present in exons, termed exonic splicing enhancers (ESEs), play important roles in constitutive and alternative splicing. A computational method, RESCUE-ESE, was developed that predicts which sequences have ESE activity by statistical analysis of exon-intron and splice site composition. When large data sets of human gene sequences were used, this method identified 10 predicted ESE motifs. Representatives of all 10 motifs were found to display enhancer activity in vivo, whereas point mutants of these sequences exhibited sharply reduced activity. The motifs identified enable prediction of the splicing phenotypes of exonic mutations in human genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fairbrother, William G -- Yeh, Ru-Fang -- Sharp, Phillip A -- Burge, Christopher B -- 1 R01 HG02439-01/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 9;297(5583):1007-13.

    Beschreibung: We present a fluorescence-based, multiplex in situ hybridization method that permits the simultaneous detection of five differently labeled antisense RNA probes and up to seven differ-ent transcripts in a single Drosophila embryo. We also show that it should be possible to increase the number of detected transcripts substantially with nascent transcript multiplex fluorescent in situ hybridization. These multiplex methods fill a current technological gap between high-resolution in situ hybridization with one or two fluorescently labeled probes and low-resolution but genome-wide microarray RNA profiling and should be of great utility in establishing gene networks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kosman, Dave -- Mizutani, Claudia M -- Lemons, Derek -- Cox, W Gregory -- McGinnis, William -- Bier, Ethan -- 28315/PHS HHS/ -- NS29870/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2004 Aug 6;305(5685):846.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Cell and Developmental Biology, University of California-San Diego, La Jolla, CA 92093, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15297669" target="_blank"〉PubMed〈/a〉
