    The role of bio-physical cohesion on subaqueous bedform size (2016)
    Wiley
    Details
    Publication Date: 2016-01-29
    Description: Biologically active, fine-grained sediment forms abundant sedimentary deposits on Earth's surface, and mixed mud-sand dominates many coasts, deltas, and estuaries. Our predictions of sediment transport and bed roughness in these environments presently rely on empirically based bedform predictors that are based exclusively on biologically inactive cohesionless silt, sand and gravel. This approach underpins many paleoenvironmental reconstructions of sedimentary successions, which rely on analysis of cross-stratification and bounding surfaces produced by migrating bedforms. Here we present controlled laboratory experiments that identify and quantify the influence of physical and biological cohesion on equilibrium bedform morphology. The results show the profound influence of biological cohesion on bedform size and identify how cohesive bonding mechanisms in different sediment mixtures govern the relationships. The findings highlight that existing bedform predictors require re-formulation for combined biophysical cohesive effects in order to improve morphodynamic model predictions and to enhance the interpretations of these environments in the geological record.

    Integrating field and laboratory approaches for ripple development in mixed sand–clay–EPS (2019)
    Wiley
    Details
    Publication Date: 2019
    Description: Abstract The shape and size of sedimentary bedforms play a key role in the reconstruction of sedimentary processes in modern and ancient environments. Recent laboratory experiments have shown that bedforms in mixed sand–clay develop at a slower rate and often have smaller heights and wavelengths than equivalent bedforms in pure sand. This effect is generally attributed to cohesive forces that can be of physical origin, caused by electrostatic forces of attraction between clay minerals, and of biological origin, caused by ‘sticky’ extracellular polymeric substances (EPS) produced by micro‐organisms, such as microalgae (microphytobenthos) and bacteria. The present study demonstrates, for the first time, that these laboratory experiments are a suitable analogue for current ripples formed by tidal currents on a natural mixed sand–mud–EPS intertidal flat in a macrotidal estuary. Integrated hydrodynamic and bed morphological measurements, collected during a spring tide under weak wave conditions near Hilbre Island (Dee Estuary, north‐west England, UK), reveal a statistically significant decrease in current ripple wavelength for progressively higher bed mud and EPS contents, and a concurrent change from three‐dimensional linguoid to two‐dimensional straight‐crested ripple planform morphology. These results agree well with observations in laboratory flumes, but the rate of decrease of ripple wavelength as mud content increased was found to be substantially greater for the field than the laboratory. Since the formation of ripples under natural conditions is inherently more complex than in the laboratory, four additional factors that might affect current ripple development in estuaries, but which were not accounted for in laboratory experiments, were explored. These were current forcing, clay type, pore water salinity and bed EPS content. These data illustrate that clay type alone cannot explain the difference in the rate of decrease in ripple wavelength, because the bed clay contents were too low for clay type to have had a measurable effect on bedform development. Accounting for the difference in current forcing between the field and experiments, and therefore the relative stage of development with respect to equilibrium ripples, increases the difference between the ripple wavelengths. The presence of strongly cohesive EPS in the current ripples on the natural intertidal flat might explain the majority of the difference in the rate of decrease in ripple wavelength between the field and the laboratory. The effect of pore water salinity on the rate of bedform development cannot be quantified at present, but salinity is postulated herein to have had a smaller influence on the ripple wavelength than bed EPS content. The common presence of clay and EPS in many aqueous sedimentary environments implies that a re‐assessment of the role of current ripples and their primary current lamination in predicting and reconstructing flow regimes is necessary, and that models that are valid for pure sand are an inappropriate descriptor for more complex mixed sediment. This study proposes that this re‐assessment is necessary at all bed clay contents above 3%.

    Disruption of the clock components CLOCK and BMAL1 leads to hypoinsulinaemia and diabetes (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-22
    Description: The molecular clock maintains energy constancy by producing circadian oscillations of rate-limiting enzymes involved in tissue metabolism across the day and night. During periods of feeding, pancreatic islets secrete insulin to maintain glucose homeostasis, and although rhythmic control of insulin release is recognized to be dysregulated in humans with diabetes, it is not known how the circadian clock may affect this process. Here we show that pancreatic islets possess self-sustained circadian gene and protein oscillations of the transcription factors CLOCK and BMAL1. The phase of oscillation of islet genes involved in growth, glucose metabolism and insulin signalling is delayed in circadian mutant mice, and both Clock and Bmal1 (also called Arntl) mutants show impaired glucose tolerance, reduced insulin secretion and defects in size and proliferation of pancreatic islets that worsen with age. Clock disruption leads to transcriptome-wide alterations in the expression of islet genes involved in growth, survival and synaptic vesicle assembly. Notably, conditional ablation of the pancreatic clock causes diabetes mellitus due to defective beta-cell function at the very latest stage of stimulus-secretion coupling. These results demonstrate a role for the beta-cell clock in coordinating insulin secretion with the sleep-wake cycle, and reveal that ablation of the pancreatic clock can trigger the onset of diabetes mellitus.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2920067/" 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/PMC2920067/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marcheva, Biliana -- Ramsey, Kathryn Moynihan -- Buhr, Ethan D -- Kobayashi, Yumiko -- Su, Hong -- Ko, Caroline H -- Ivanova, Ganka -- Omura, Chiaki -- Mo, Shelley -- Vitaterna, Martha H -- Lopez, James P -- Philipson, Louis H -- Bradfield, Christopher A -- Crosby, Seth D -- JeBailey, Lellean -- Wang, Xiaozhong -- Takahashi, Joseph S -- Bass, Joseph -- P01 AG011412/AG/NIA NIH HHS/ -- P01 AG011412-080011/AG/NIA NIH HHS/ -- R01 HL097817/HL/NHLBI NIH HHS/ -- R01 HL097817-01/HL/NHLBI NIH HHS/ -- R37 ES005703/ES/NIEHS NIH HHS/ -- R37-ES-005703/ES/NIEHS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Jul 29;466(7306):627-31. doi: 10.1038/nature09253.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Northwestern University Feinberg School of Medicine, Chicago, Illinois 60611, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20562852" target="_blank"〉PubMed〈/a〉

    The landscape of somatic copy-number alteration across human cancers (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-19
    Description: A powerful way to discover key genes with causal roles in oncogenesis is to identify genomic regions that undergo frequent alteration in human cancers. Here we present high-resolution analyses of somatic copy-number alterations (SCNAs) from 3,131 cancer specimens, belonging largely to 26 histological types. We identify 158 regions of focal SCNA that are altered at significant frequency across several cancer types, of which 122 cannot be explained by the presence of a known cancer target gene located within these regions. Several gene families are enriched among these regions of focal SCNA, including the BCL2 family of apoptosis regulators and the NF-kappaBeta pathway. We show that cancer cells containing amplifications surrounding the MCL1 and BCL2L1 anti-apoptotic genes depend on the expression of these genes for survival. Finally, we demonstrate that a large majority of SCNAs identified in individual cancer types are present in several cancer types.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826709/" 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/PMC2826709/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beroukhim, Rameen -- Mermel, Craig H -- Porter, Dale -- Wei, Guo -- Raychaudhuri, Soumya -- Donovan, Jerry -- Barretina, Jordi -- Boehm, Jesse S -- Dobson, Jennifer -- Urashima, Mitsuyoshi -- Mc Henry, Kevin T -- Pinchback, Reid M -- Ligon, Azra H -- Cho, Yoon-Jae -- Haery, Leila -- Greulich, Heidi -- Reich, Michael -- Winckler, Wendy -- Lawrence, Michael S -- Weir, Barbara A -- Tanaka, Kumiko E -- Chiang, Derek Y -- Bass, Adam J -- Loo, Alice -- Hoffman, Carter -- Prensner, John -- Liefeld, Ted -- Gao, Qing -- Yecies, Derek -- Signoretti, Sabina -- Maher, Elizabeth -- Kaye, Frederic J -- Sasaki, Hidefumi -- Tepper, Joel E -- Fletcher, Jonathan A -- Tabernero, Josep -- Baselga, Jose -- Tsao, Ming-Sound -- Demichelis, Francesca -- Rubin, Mark A -- Janne, Pasi A -- Daly, Mark J -- Nucera, Carmelo -- Levine, Ross L -- Ebert, Benjamin L -- Gabriel, Stacey -- Rustgi, Anil K -- Antonescu, Cristina R -- Ladanyi, Marc -- Letai, Anthony -- Garraway, Levi A -- Loda, Massimo -- Beer, David G -- True, Lawrence D -- Okamoto, Aikou -- Pomeroy, Scott L -- Singer, Samuel -- Golub, Todd R -- Lander, Eric S -- Getz, Gad -- Sellers, William R -- Meyerson, Matthew -- K08 AR055688/AR/NIAMS NIH HHS/ -- K08 AR055688-03/AR/NIAMS NIH HHS/ -- K08 AR055688-04/AR/NIAMS NIH HHS/ -- K08 CA122833/CA/NCI NIH HHS/ -- K08 CA122833-01A1/CA/NCI NIH HHS/ -- K08 CA122833-02/CA/NCI NIH HHS/ -- K08 CA122833-03/CA/NCI NIH HHS/ -- K08 CA134931/CA/NCI NIH HHS/ -- K08CA122833/CA/NCI NIH HHS/ -- P01CA 098101/CA/NCI NIH HHS/ -- P01CA085859/CA/NCI NIH HHS/ -- P50CA90578/CA/NCI NIH HHS/ -- R01 CA109038/CA/NCI NIH HHS/ -- R01 GM074024/GM/NIGMS NIH HHS/ -- R01CA109038/CA/NCI NIH HHS/ -- R01CA109467/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- U24 CA126546/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Feb 18;463(7283):899-905. doi: 10.1038/nature08822.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer Program and Medical and Population Genetics Group, The Broad Institute of M.I.T. and Harvard, 7 Cambridge Center.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20164920" target="_blank"〉PubMed〈/a〉

    CDK8 is a colorectal cancer oncogene that regulates beta-catenin activity (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-09-17
    Description: Aberrant activation of the canonical WNT/beta-catenin pathway occurs in almost all colorectal cancers and contributes to their growth, invasion and survival. Although dysregulated beta-catenin activity drives colon tumorigenesis, further genetic perturbations are required to elaborate full malignant transformation. To identify genes that both modulate beta-catenin activity and are essential for colon cancer cell proliferation, we conducted two loss-of-function screens in human colon cancer cells and compared genes identified in these screens with an analysis of copy number alterations in colon cancer specimens. One of these genes, CDK8, which encodes a member of the mediator complex, is located at 13q12.13, a region of recurrent copy number gain in a substantial fraction of colon cancers. Here we show that the suppression of CDK8 expression inhibits proliferation in colon cancer cells characterized by high levels of CDK8 and beta-catenin hyperactivity. CDK8 kinase activity was necessary for beta-catenin-driven transformation and for expression of several beta-catenin transcriptional targets. Together these observations suggest that therapeutic interventions targeting CDK8 may confer a clinical benefit in beta-catenin-driven malignancies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2587138/" 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/PMC2587138/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Firestein, Ron -- Bass, Adam J -- Kim, So Young -- Dunn, Ian F -- Silver, Serena J -- Guney, Isil -- Freed, Ellen -- Ligon, Azra H -- Vena, Natalie -- Ogino, Shuji -- Chheda, Milan G -- Tamayo, Pablo -- Finn, Stephen -- Shrestha, Yashaswi -- Boehm, Jesse S -- Jain, Supriya -- Bojarski, Emeric -- Mermel, Craig -- Barretina, Jordi -- Chan, Jennifer A -- Baselga, Jose -- Tabernero, Josep -- Root, David E -- Fuchs, Charles S -- Loda, Massimo -- Shivdasani, Ramesh A -- Meyerson, Matthew -- Hahn, William C -- K08 CA134931/CA/NCI NIH HHS/ -- P50CA127003/CA/NCI NIH HHS/ -- R33 CA128625/CA/NCI NIH HHS/ -- R33 CA128625-01A1/CA/NCI NIH HHS/ -- R33CA128625/CA/NCI NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Sep 25;455(7212):547-51. doi: 10.1038/nature07179.

    Circadian clock NAD+ cycle drives mitochondrial oxidative metabolism in mice (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-09-21
    Description: Circadian clocks are self-sustained cellular oscillators that synchronize oxidative and reductive cycles in anticipation of the solar cycle. We found that the clock transcription feedback loop produces cycles of nicotinamide adenine dinucleotide (NAD(+)) biosynthesis, adenosine triphosphate production, and mitochondrial respiration through modulation of mitochondrial protein acetylation to synchronize oxidative metabolic pathways with the 24-hour fasting and feeding cycle. Circadian control of the activity of the NAD(+)-dependent deacetylase sirtuin 3 (SIRT3) generated rhythms in the acetylation and activity of oxidative enzymes and respiration in isolated mitochondria, and NAD(+) supplementation restored protein deacetylation and enhanced oxygen consumption in circadian mutant mice. Thus, circadian control of NAD(+) bioavailability modulates mitochondrial oxidative function and organismal metabolism across the daily cycles of fasting and feeding.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3963134/" 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/PMC3963134/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peek, Clara Bien -- Affinati, Alison H -- Ramsey, Kathryn Moynihan -- Kuo, Hsin-Yu -- Yu, Wei -- Sena, Laura A -- Ilkayeva, Olga -- Marcheva, Biliana -- Kobayashi, Yumiko -- Omura, Chiaki -- Levine, Daniel C -- Bacsik, David J -- Gius, David -- Newgard, Christopher B -- Goetzman, Eric -- Chandel, Navdeep S -- Denu, John M -- Mrksich, Milan -- Bass, Joseph -- 5P01HL071643-10/HL/NHLBI NIH HHS/ -- 5P30AR057216-05/AR/NIAMS NIH HHS/ -- F30 DK085936/DK/NIDDK NIH HHS/ -- F30 ES019815/ES/NIEHS NIH HHS/ -- F32 DK092034/DK/NIDDK NIH HHS/ -- P01 AG011412/AG/NIA NIH HHS/ -- P01AG011412-16/AG/NIA NIH HHS/ -- P01DK58398/DK/NIDDK NIH HHS/ -- P30 CA014520/CA/NCI NIH HHS/ -- R01 AG038679/AG/NIA NIH HHS/ -- R01 CA152601-01/CA/NCI NIH HHS/ -- R01 CA152799-01A1/CA/NCI NIH HHS/ -- R01 CA16383801A1/CA/NCI NIH HHS/ -- R01 CA168292/CA/NCI NIH HHS/ -- R01 CA168292-01A1/CA/NCI NIH HHS/ -- R01 DK090242/DK/NIDDK NIH HHS/ -- R01 DK090625/DK/NIDDK NIH HHS/ -- R01 GM065386/GM/NIGMS NIH HHS/ -- R01 HL097817/HL/NHLBI NIH HHS/ -- R01DK090242-03/DK/NIDDK NIH HHS/ -- R01DK090625-01A1/DK/NIDDK NIH HHS/ -- R01HL097817-01/HL/NHLBI NIH HHS/ -- R37 GM059785/GM/NIGMS NIH HHS/ -- T32 DK007169/DK/NIDDK NIH HHS/ -- T32 GM008152/GM/NIGMS NIH HHS/ -- T32 HL007909/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Nov 1;342(6158):1243417. doi: 10.1126/science.1243417.

    Obesity and metabolic syndrome in circadian Clock mutant mice (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-04-23
    Description: The CLOCK transcription factor is a key component of the molecular circadian clock within pacemaker neurons of the hypothalamic suprachiasmatic nucleus. We found that homozygous Clock mutant mice have a greatly attenuated diurnal feeding rhythm, are hyperphagic and obese, and develop a metabolic syndrome of hyperleptinemia, hyperlipidemia, hepatic steatosis, hyperglycemia, and hypoinsulinemia. Expression of transcripts encoding selected hypothalamic peptides associated with energy balance was attenuated in the Clock mutant mice. These results suggest that the circadian clock gene network plays an important role in mammalian energy balance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764501/" 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/PMC3764501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turek, Fred W -- Joshu, Corinne -- Kohsaka, Akira -- Lin, Emily -- Ivanova, Ganka -- McDearmon, Erin -- Laposky, Aaron -- Losee-Olson, Sue -- Easton, Amy -- Jensen, Dalan R -- Eckel, Robert H -- Takahashi, Joseph S -- Bass, Joseph -- AG11412/AG/NIA NIH HHS/ -- AG18200/AG/NIA NIH HHS/ -- DK02675/DK/NIDDK NIH HHS/ -- DK26356/DK/NIDDK NIH HHS/ -- HL59598/HL/NHLBI NIH HHS/ -- HL75029/HL/NHLBI NIH HHS/ -- K08 DK002675/DK/NIDDK NIH HHS/ -- P01 AG011412/AG/NIA NIH HHS/ -- R01 AG018200/AG/NIA NIH HHS/ -- R01 DK026356/DK/NIDDK NIH HHS/ -- R01 HL059598/HL/NHLBI NIH HHS/ -- R01 HL075029/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2005 May 13;308(5724):1043-5.
