    Description: The mevalonate-derived portion of a prenylated protein from Chinese hamster ovary cells has been established as diterpenoid (C20). This group is linked to a carboxyl-terminal cysteine as a thioether. It was removed from the protein by hydrazinolysis followed by Raney nickel desulfurization, and the resulting hydrocarbon fraction was analyzed by gas chromatography-mass spectrometry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rilling, H C -- Breunger, E -- Epstein, W W -- Crain, P F -- GM 29812/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jan 19;247(4940):318-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Utah, Salt Lake City 84112.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2296720" target="_blank"〉PubMed〈/a〉

    Description: Blisters following minor trauma characterize epidermolysis bullosa, a group of hereditary diseases of the skin. In the simplex type, epidermal basal cells are fragile, and mutations of genes encoding keratin intermediate filament proteins underlie that fragility. In the dystrophic types, the causative mutation appears to be in the gene encoding type VII collagen, which is the major component of anchoring fibrils. These recent findings afford solid evidence that at least one function of the cytoskeletal intermediate filament network is the provision of mechanical stability and that anchoring fibrils indeed do anchor the epidermis to the underlying dermis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epstein, E H Jr -- New York, N.Y. -- Science. 1992 May 8;256(5058):799-804.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of California, San Francisco, San Francisco General Hospital 94110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1375393" target="_blank"〉PubMed〈/a〉

    Description: Epidermolysis bullosa simplex (EBS) is characterized by skin blistering due to basal keratinocyte fragility. In one family studied, inheritance of EBS is linked to the gene encoding keratin 14, and a thymine to cytosine mutation in exon 6 of keratin 14 has introduced a proline in the middle of an alpha-helical region. In a second family, inheritance of EBS is linked to loci that map near the keratin 5 gene. These data indicate that abnormalities of either of the components of the keratin intermediate filament heterodipolymer can impair the mechanical stability of these epithelial cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bonifas, J M -- Rothman, A L -- Epstein, E H Jr -- R01-AR28069/AR/NIAMS NIH HHS/ -- R01-AR39953/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Nov 22;254(5035):1202-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Dermatology, San Francisco General Hospital, University of California 94110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1720261" target="_blank"〉PubMed〈/a〉

    Description: Recent experiments on the chlorite-iodide-malonic acid-starch reaction in a gel reactor give the first evidence of the existence of the symmetry breaking, reaction-diffusion structures predicted by Turing in 1952. A five-variable model that describes the temporal behavior of the system is reduced to a two-variable model, and its spatial behavior is analyzed. Structures have been found with wavelengths that are in good agreement with those observed experimentally. The gel plays a key role by binding key iodine species, thereby creating the necessary difference in the effective diffusion coefficients of the activator and inhibitor species, iodide and chlorite ions, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lengyel, I -- Epstein, I R -- New York, N.Y. -- Science. 1991 Feb 8;251(4994):650-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17741380" target="_blank"〉PubMed〈/a〉

    Description: The challenge presented by myofibril assembly in striated muscle is to understand the molecular mechanisms by which its protein components are arranged at each level of organization. Recent advances in the genetics and cell biology of muscle development have shown that in vivo assembly of the myofilaments requires a complex array of structural and associated proteins and that organization of whole sarcomeres occurs initially at the cell membrane. These studies have been complemented by in vitro analyses of the renaturation, polymerization, and three-dimensional structure of the purified proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epstein, H F -- Fischman, D A -- AR-32147/AR/NIAMS NIH HHS/ -- GM-33223/GM/NIGMS NIH HHS/ -- HL-42267/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Mar 1;251(4997):1039-44.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1998120" target="_blank"〉PubMed〈/a〉

    Description: Oxygen deprivation is rapidly deleterious for most organisms. However, Caenorhabditis elegans has developed the ability to survive anoxia for at least 48 hours. Mutations in the DAF-2/DAF-16 insulin-like signaling pathway promote such survival. We describe a pathway involving the HYL-2 ceramide synthase that acts independently of DAF-2. Loss of the ceramide synthase gene hyl-2 results in increased sensitivity of C. elegans to anoxia. C. elegans has two ceramide synthases, hyl-1 and hyl-2, that participate in ceramide biogenesis and affect its ability to survive anoxic conditions. In contrast to hyl-2(lf) mutants, hyl-1(lf) mutants are more resistant to anoxia than normal animals. HYL-1 and HYL-2 have complementary specificities for fatty acyl chains. These data indicate that specific ceramides produced by HYL-2 confer resistance to anoxia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Menuz, Vincent -- Howell, Kate S -- Gentina, Sebastien -- Epstein, Sharon -- Riezman, Isabelle -- Fornallaz-Mulhauser, Monique -- Hengartner, Michael O -- Gomez, Marie -- Riezman, Howard -- Martinou, Jean-Claude -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):381-4. doi: 10.1126/science.1168532.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Geneva, CH-1211 Geneva 4, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372430" target="_blank"〉PubMed〈/a〉

    Description: Stripe rust is a devastating fungal disease that afflicts wheat in many regions of the world. New races of Puccinia striiformis, the pathogen responsible for this disease, have overcome most of the known race-specific resistance genes. We report the map-based cloning of the gene Yr36 (WKS1), which confers resistance to a broad spectrum of stripe rust races at relatively high temperatures (25 degrees to 35 degrees C). This gene includes a kinase and a putative START lipid-binding domain. Five independent mutations and transgenic complementation confirmed that both domains are necessary to confer resistance. Yr36 is present in wild wheat but is absent in modern pasta and bread wheat varieties, and therefore it can now be used to improve resistance to stripe rust in a broad set of varieties.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4737487/" 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/PMC4737487/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fu, Daolin -- Uauy, Cristobal -- Distelfeld, Assaf -- Blechl, Ann -- Epstein, Lynn -- Chen, Xianming -- Sela, Hanan -- Fahima, Tzion -- Dubcovsky, Jorge -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1357-60. doi: 10.1126/science.1166289.

    Description: Intestinal epithelial stem cell identity and location have been the subject of substantial research. Cells in the +4 niche are slow-cycling and label-retaining, whereas a different stem cell niche located at the crypt base is occupied by crypt base columnar (CBC) cells. CBCs are distinct from +4 cells, and the relationship between them is unknown, though both give rise to all intestinal epithelial lineages. We demonstrate that Hopx, an atypical homeobox protein, is a specific marker of +4 cells. Hopx-expressing cells give rise to CBCs and all mature intestinal epithelial lineages. Conversely, CBCs can give rise to +4 Hopx-positive cells. These findings demonstrate a bidirectional lineage relationship between active and quiescent stem cells in their niches.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3705713/" 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/PMC3705713/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Norifumi -- Jain, Rajan -- LeBoeuf, Matthew R -- Wang, Qiaohong -- Lu, Min Min -- Epstein, Jonathan A -- R01 HL071546/HL/NHLBI NIH HHS/ -- U01 HL100405/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Dec 9;334(6061):1420-4. doi: 10.1126/science.1213214.
