    Evolutionary discrimination of mammalian conserved non-genic sequences (CNGs) (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-10-04
    Description: Analysis of the human and mouse genomes identified an abundance of conserved non-genic sequences (CNGs). The significance and evolutionary depth of their conservation remain unanswered. We have quantified levels and patterns of conservation of 191 CNGs of human chromosome 21 in 14 mammalian species. We found that CNGs are significantly more conserved than protein-coding genes and noncoding RNAS (ncRNAs) within the mammalian class from primates to monotremes to marsupials. The pattern of substitutions in CNGs differed from that seen in protein-coding and ncRNA genes and resembled that of protein-binding regions. About 0.3% to 1% of the human genome corresponds to a previously unknown class of extremely constrained CNGs shared among mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dermitzakis, Emmanouil T -- Reymond, Alexandre -- Scamuffa, Nathalie -- Ucla, Catherine -- Kirkness, Ewen -- Rossier, Colette -- Antonarakis, Stylianos E -- New York, N.Y. -- Science. 2003 Nov 7;302(5647):1033-5.

    CFTR as a cAMP-dependent regulator of sodium channels (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-08-11
    Description: Cystic fibrosis transmembrane regulator (CFTR), the gene product that is mutated in cystic fibrosis (CF) patients, has a well-recognized function as a cyclic adenosine 3',5'-monophosphate (cAMP)-regulated chloride channel, but this property does not account for the abnormally high basal rate and cAMP sensitivity of sodium ion absorption in CF airway epithelia. Expression of complementary DNAs for rat epithelial Na+ channel (rENaC) alone in Madin Darby canine kidney (MDCK) epithelial cells generated large amiloride-sensitive sodium currents that were stimulated by cAMP, whereas coexpression of human CFTR with rENaC generated smaller basal sodium currents that were inhibited by cAMP. Parallel studies that measured regulation of sodium permeability in fibroblasts showed similar results. In CF airway epithelia, the absence of this second function of CFTR as a cAMP-dependent regulator likely accounts for abnormal sodium transport.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stutts, M J -- Canessa, C M -- Olsen, J C -- Hamrick, M -- Cohn, J A -- Rossier, B C -- Boucher, R C -- CFF R026/PHS HHS/ -- HL 34322/HL/NHLBI NIH HHS/ -- HL 42384/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1995 Aug 11;269(5225):847-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cystic Fibrosis/Pulmonary Research and Treatment Center, University of North Carolina at Chapel Hill 27599-7020, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7543698" target="_blank"〉PubMed〈/a〉

    National Academy of Sciences
    Details
    Publication Date: 2013-06-26
    Description: The Drosophila defense against pathogens largely relies on the activation of two signaling pathways: immune deficiency (IMD) and Toll. The IMD pathway is triggered mainly by Gram-negative bacteria, whereas the Toll pathway responds predominantly to Gram-positive bacteria and fungi. The activation of these pathways leads to the rapid induction of...

    Electron microscopy of selectively stimulated microconidiogenesis in wild type Neurospora crassa (1973)
    Springer

    Details
    ISSN: 1432-072X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Microconidiogenesis in Neurospora crassa wild type is selectively stimulated by iodoacetate. The ultrastructural features of various stages of microconidiogenesis have been studied. The conidiogenous cells or phialides first bear a protuberance which then erupts into a conspicuous collarette surrounding, above a lamellated cushion, the successively budded, often elongated microconidia.

    Notes: Abstract In iodoacetate-treated microconidiating cultures of Neurospora crassa, mycelial yield, sucrose consumption and ethanol production are reduced. The specific activity of glyceraldehyde-3-phosphate dehydrogenase is sharply decreased while the specific activities of glucose-6-phosphate dehydrogenase and of 6-phosphogluconate dehydrogenase are stimulated. A polyphenoloxidase is induced in the microconidiating cultures.

    Structure of the human Lanosterol Synthase gene and its analysis as a candidate for holoprosencephaly (HPE1) (1999)

    Notes: Abstract. Holoprosencephaly (HPE) is the most common birth defect of the brain in humans. It involves various degrees of incomplete separation of the cerebrum into distinct left and right halves, and it is frequently accompanied by craniofacial anomalies. The HPE1 locus in human chromosome 21q22.3 is one of a dozen putative genetic loci implicated in causing HPE. Here, we report the complete gene structure of the human lanosterol synthase (LS) gene, which is located in this interval, and present its mutational analysis in HPE patients. We considered LS an excellent candidate HPE gene because of the requirement for cholesterol modification of the Sonic Hedgehog protein for the correct patterning activity of this HPE-associated protein. Despite extensive pedigree analysis of numerous polymorphisms, as well as complementation studies in yeast on one of the missense mutations, we find no evidence that the LS gene is in fact HPE1, implicating another gene located in this chromosomal region in HPE pathogenesis.

    A testis-specific gene, TPTE, encodes a putative transmembrane tyrosine phosphatase and maps to the pericentromeric region of human chromosomes 21 and 13, and to chromosomes 15, 22, and Y (1999)

    Notes: Abstract. To contribute to the creation of a transcription map of human chromosome 21 (HC21) and to the identification of genes that may be involved in the pathogenesis of Down syndrome, exon trapping was performed from HC21-specific cosmids covering the entire chromosome. More than 700 exons have been identified to date. One such exon, hmc01a06, maps to YAC 831B6 which contains marker D21Z1 (alphoid repeats) and had previously been localized to the pericentromeric region of HC21. Northern-blot analysis revealed a 2.5-kb mRNA species strongly and exclusively expressed in the testis. We cloned the corresponding full-length cDNA, which encodes a predicted polypeptide of 551 amino acids with at least two potential transmembrane domains and a tyrosine phosphatase motif. The cDNA has sequence homology to chicken tensin, bovine auxilin and rat cyclin-G associated kinase (GAK). The entire polypeptide sequence also has significant homology to tumor suppressor PTEN/MMAC1 protein. We termed this novel gene/protein TPTE (transmembrane phosphatase with tensin homology). Polymerase chain reaction amplification, fluorescent in situ hybridization, Southern-blot and sequence analysis using monochromosomal somatic cell hybrids showed that this gene has highly homologous copies on HC13, 15, 22, and Y, in addition to its HC21 copy or copies. The estimated minimum number of copies of the TPTE gene in the haploid human genome is 7 in male and 6 in female. Zoo-blot analysis showed that TPTE is conserved between humans and other species. The biological function of the TPTE gene is presently unknown; however, its expression pattern, sequence homologies, and the presence of a potential tyrosine phosphatase domain suggest that it may be involved in signal transduction pathways of the endocrine or spermatogenetic function of the testis. It is also unknown whether all copies of TPTE are functional or whether some are pseudogenes. TPTE is, to our knowledge, the gene located closest to the human centromeric sequences.
