    Impacts of wind stress on the Antarctic Circumpolar Current fronts and associated subduction (2011)
    Wiley
    Details
    Publication Date: 2011-06-14
    Description: Recent studies suggest that the overturning circulation in the Antarctic Circumpolar Current (ACC) region shows a weak sensitivity to overlying wind stress changes, due to balancing of changes in the eddy-induced and Eulerian mean transports. Using an eddy-permitting coupled climate model, we analyze the response of the ACC transport, and associated water mass subduction rates, in response to an idealized poleward shift and intensification of the westerlies. As in previous studies, we find a small increase in the net ACC transport, and a poleward shift in the mean position of the ACC flow. However, the ACC is restructured, with the Subantarctic Front (SAF) and Polar Front (PF) branches shifting poleward by between 0.9° and 2.5° of latitude, resulting in a weaker ACC flow in both the SAF and PF zones. The wind stress anomaly drives a stronger northward Ekman transport of cool surface waters, deepening the winter mixed layer and causing a 12.7 Sv increase in the subduction of Subantarctic Mode Water (SAMW) north of the SAF zone and a 6.5 Sv increase in the subduction of Antarctic Intermediate Water (AAIW) within the SAF and PF zones. Our results suggest that changes in the wind stress restructure the Southern Ocean large-scale circulation, including the flow of the ACC in its primary jets, and that this affects the formation rates of SAMW and AAIW in this complex region.

    Cryptochromes mediate rhythmic repression of the glucocorticoid receptor (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-12-16
    Description: Mammalian metabolism is highly circadian and major hormonal circuits involving nuclear hormone receptors display interlinked diurnal cycling. However, mechanisms that logically explain the coordination of nuclear hormone receptors and the clock are poorly understood. Here we show that two circadian co-regulators, cryptochromes 1 and 2, interact with the glucocorticoid receptor in a ligand-dependent fashion and globally alter the transcriptional response to glucocorticoids in mouse embryonic fibroblasts: cryptochrome deficiency vastly decreases gene repression and approximately doubles the number of dexamethasone-induced genes, suggesting that cryptochromes broadly oppose glucocorticoid receptor activation and promote repression. In mice, genetic loss of cryptochrome 1 and/or 2 results in glucose intolerance and constitutively high levels of circulating corticosterone, suggesting reduced suppression of the hypothalamic-pituitary-adrenal axis coupled with increased glucocorticoid transactivation in the liver. Genomically, cryptochromes 1 and 2 associate with a glucocorticoid response element in the phosphoenolpyruvate carboxykinase 1 promoter in a hormone-dependent manner, and dexamethasone-induced transcription of the phosphoenolpyruvate carboxykinase 1 gene was strikingly increased in cryptochrome-deficient livers. These results reveal a specific mechanism through which cryptochromes couple the activity of clock and receptor target genes to complex genomic circuits underpinning normal metabolic homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3245818/" 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/PMC3245818/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamia, Katja A -- Papp, Stephanie J -- Yu, Ruth T -- Barish, Grant D -- Uhlenhaut, N Henriette -- Jonker, Johan W -- Downes, Michael -- Evans, Ronald M -- DK057978/DK/NIDDK NIH HHS/ -- DK062434/DK/NIDDK NIH HHS/ -- DK090188/DK/NIDDK NIH HHS/ -- K01 DK090188/DK/NIDDK NIH HHS/ -- K01 DK090188-01/DK/NIDDK NIH HHS/ -- K01 DK090188-02/DK/NIDDK NIH HHS/ -- P30 CA014195/CA/NCI NIH HHS/ -- R37 DK057978/DK/NIDDK NIH HHS/ -- R37 DK057978-22/DK/NIDDK NIH HHS/ -- U19 DK062434/DK/NIDDK NIH HHS/ -- U19 DK062434-01/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Dec 14;480(7378):552-6. doi: 10.1038/nature10700.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, The Salk Institute for Biological Studies, 10010 North Torrey Pines Road, La Jolla, California 92037, USA. klamia@scripps.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22170608" target="_blank"〉PubMed〈/a〉

    Endocrinization of FGF1 produces a neomorphic and potent insulin sensitizer (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-07-22
    Description: Fibroblast growth factor 1 (FGF1) is an autocrine/paracrine regulator whose binding to heparan sulphate proteoglycans effectively precludes its circulation. Although FGF1 is known as a mitogenic factor, FGF1 knockout mice develop insulin resistance when stressed by a high-fat diet, suggesting a potential role in nutrient homeostasis. Here we show that parenteral delivery of a single dose of recombinant FGF1 (rFGF1) results in potent, insulin-dependent lowering of glucose levels in diabetic mice that is dose-dependent but does not lead to hypoglycaemia. Chronic pharmacological treatment with rFGF1 increases insulin-dependent glucose uptake in skeletal muscle and suppresses the hepatic production of glucose to achieve whole-body insulin sensitization. The sustained glucose lowering and insulin sensitization attributed to rFGF1 are not accompanied by the side effects of weight gain, liver steatosis and bone loss associated with current insulin-sensitizing therapies. We also show that the glucose-lowering activity of FGF1 can be dissociated from its mitogenic activity and is mediated predominantly via FGF receptor 1 signalling. Thus we have uncovered an unexpected, neomorphic insulin-sensitizing action for exogenous non-mitogenic human FGF1 with therapeutic potential for the treatment of insulin resistance and type 2 diabetes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4184286/" 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/PMC4184286/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suh, Jae Myoung -- Jonker, Johan W -- Ahmadian, Maryam -- Goetz, Regina -- Lackey, Denise -- Osborn, Olivia -- Huang, Zhifeng -- Liu, Weilin -- Yoshihara, Eiji -- van Dijk, Theo H -- Havinga, Rick -- Fan, Weiwei -- Yin, Yun-Qiang -- Yu, Ruth T -- Liddle, Christopher -- Atkins, Annette R -- Olefsky, Jerrold M -- Mohammadi, Moosa -- Downes, Michael -- Evans, Ronald M -- DE13686/DE/NIDCR NIH HHS/ -- DK-033651/DK/NIDDK NIH HHS/ -- DK-063491/DK/NIDDK NIH HHS/ -- DK-074868/DK/NIDDK NIH HHS/ -- DK057978/DK/NIDDK NIH HHS/ -- DK090962/DK/NIDDK NIH HHS/ -- ES010337/ES/NIEHS NIH HHS/ -- HL088093/HL/NHLBI NIH HHS/ -- HL105278/HL/NHLBI NIH HHS/ -- P01 DK054441/DK/NIDDK NIH HHS/ -- P01 DK074868/DK/NIDDK NIH HHS/ -- P01 HL088093/HL/NHLBI NIH HHS/ -- P01-DK054441-14A1/DK/NIDDK NIH HHS/ -- P30 DK063491/DK/NIDDK NIH HHS/ -- P42 ES010337/ES/NIEHS NIH HHS/ -- R01 HL105278/HL/NHLBI NIH HHS/ -- R24 DK090962/DK/NIDDK NIH HHS/ -- R37 DK033651/DK/NIDDK NIH HHS/ -- R37 DK057978/DK/NIDDK NIH HHS/ -- T32 DK007494/DK/NIDDK NIH HHS/ -- T32-DK-007494/DK/NIDDK NIH HHS/ -- U54 HD012303/HD/NICHD NIH HHS/ -- U54-HD-012303-25/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Sep 18;513(7518):436-9. doi: 10.1038/nature13540.

    Hotspots of aberrant epigenomic reprogramming in human induced pluripotent stem cells (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-02-04
    Description: Induced pluripotent stem cells (iPSCs) offer immense potential for regenerative medicine and studies of disease and development. Somatic cell reprogramming involves epigenomic reconfiguration, conferring iPSCs with characteristics similar to embryonic stem (ES) cells. However, it remains unknown how complete the reestablishment of ES-cell-like DNA methylation patterns is throughout the genome. Here we report the first whole-genome profiles of DNA methylation at single-base resolution in five human iPSC lines, along with methylomes of ES cells, somatic cells, and differentiated iPSCs and ES cells. iPSCs show significant reprogramming variability, including somatic memory and aberrant reprogramming of DNA methylation. iPSCs share megabase-scale differentially methylated regions proximal to centromeres and telomeres that display incomplete reprogramming of non-CG methylation, and differences in CG methylation and histone modifications. Lastly, differentiation of iPSCs into trophoblast cells revealed that errors in reprogramming CG methylation are transmitted at a high frequency, providing an iPSC reprogramming signature that is maintained after differentiation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3100360/" 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/PMC3100360/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, Ryan -- Pelizzola, Mattia -- Kida, Yasuyuki S -- Hawkins, R David -- Nery, Joseph R -- Hon, Gary -- Antosiewicz-Bourget, Jessica -- O'Malley, Ronan -- Castanon, Rosa -- Klugman, Sarit -- Downes, Michael -- Yu, Ruth -- Stewart, Ron -- Ren, Bing -- Thomson, James A -- Evans, Ronald M -- Ecker, Joseph R -- 1U01ES017166-01/ES/NIEHS NIH HHS/ -- DK062434/DK/NIDDK NIH HHS/ -- P30 CA014195/CA/NCI NIH HHS/ -- U01 ES017166/ES/NIEHS NIH HHS/ -- U01 ES017166-01/ES/NIEHS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Mar 3;471(7336):68-73. doi: 10.1038/nature09798.

    Regulation of circadian behaviour and metabolism by REV-ERB-alpha and REV-ERB-beta (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-31
    Description: The circadian clock acts at the genomic level to coordinate internal behavioural and physiological rhythms via the CLOCK-BMAL1 transcriptional heterodimer. Although the nuclear receptors REV-ERB-alpha and REV-ERB-beta have been proposed to form an accessory feedback loop that contributes to clock function, their precise roles and importance remain unresolved. To establish their regulatory potential, we determined the genome-wide cis-acting targets (cistromes) of both REV-ERB isoforms in murine liver, which revealed shared recognition at over 50% of their total DNA binding sites and extensive overlap with the master circadian regulator BMAL1. Although REV-ERB-alpha has been shown to regulate Bmal1 expression directly, our cistromic analysis reveals a more profound connection between BMAL1 and the REV-ERB-alpha and REV-ERB-beta genomic regulatory circuits than was previously suspected. Genes within the intersection of the BMAL1, REV-ERB-alpha and REV-ERB-beta cistromes are highly enriched for both clock and metabolic functions. As predicted by the cistromic analysis, dual depletion of Rev-erb-alpha and Rev-erb-beta function by creating double-knockout mice profoundly disrupted circadian expression of core circadian clock and lipid homeostatic gene networks. As a result, double-knockout mice show markedly altered circadian wheel-running behaviour and deregulated lipid metabolism. These data now unite REV-ERB-alpha and REV-ERB-beta with PER, CRY and other components of the principal feedback loop that drives circadian expression and indicate a more integral mechanism for the coordination of circadian rhythm and metabolism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3367514/" 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/PMC3367514/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho, Han -- Zhao, Xuan -- Hatori, Megumi -- Yu, Ruth T -- Barish, Grant D -- Lam, Michael T -- Chong, Ling-Wa -- DiTacchio, Luciano -- Atkins, Annette R -- Glass, Christopher K -- Liddle, Christopher -- Auwerx, Johan -- Downes, Michael -- Panda, Satchidananda -- Evans, Ronald M -- DK057978/DK/NIDDK NIH HHS/ -- DK062434/DK/NIDDK NIH HHS/ -- DK090962/DK/NIDDK NIH HHS/ -- DK091618/DK/NIDDK NIH HHS/ -- HL105278/HL/NHLBI NIH HHS/ -- P30 CA014195/CA/NCI NIH HHS/ -- R01 DK091618/DK/NIDDK NIH HHS/ -- R01 HL105278/HL/NHLBI NIH HHS/ -- R01 HL105278-21/HL/NHLBI NIH HHS/ -- R24 DK090962/DK/NIDDK NIH HHS/ -- R24 DK090962-02/DK/NIDDK NIH HHS/ -- R37 DK057978/DK/NIDDK NIH HHS/ -- R37 DK057978-34/DK/NIDDK NIH HHS/ -- T32 HL007770/HL/NHLBI NIH HHS/ -- T32 HL007770-15/HL/NHLBI NIH HHS/ -- T32-HL007770/HL/NHLBI NIH HHS/ -- U19 DK062434/DK/NIDDK NIH HHS/ -- U19 DK062434-10/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Mar 29;485(7396):123-7. doi: 10.1038/nature11048.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, Salk Institute for Biological Studies, La Jolla, California 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22460952" target="_blank"〉PubMed〈/a〉

    A PPARgamma-FGF1 axis is required for adaptive adipose remodelling and metabolic homeostasis (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-04-24
    Description: Although feast and famine cycles illustrate that remodelling of adipose tissue in response to fluctuations in nutrient availability is essential for maintaining metabolic homeostasis, the underlying mechanisms remain poorly understood. Here we identify fibroblast growth factor 1 (FGF1) as a critical transducer in this process in mice, and link its regulation to the nuclear receptor PPARgamma (peroxisome proliferator activated receptor gamma), which is the adipocyte master regulator and the target of the thiazolidinedione class of insulin sensitizing drugs. FGF1 is the prototype of the 22-member FGF family of proteins and has been implicated in a range of physiological processes, including development, wound healing and cardiovascular changes. Surprisingly, FGF1 knockout mice display no significant phenotype under standard laboratory conditions. We show that FGF1 is highly induced in adipose tissue in response to a high-fat diet and that mice lacking FGF1 develop an aggressive diabetic phenotype coupled to aberrant adipose expansion when challenged with a high-fat diet. Further analysis of adipose depots in FGF1-deficient mice revealed multiple histopathologies in the vasculature network, an accentuated inflammatory response, aberrant adipocyte size distribution and ectopic expression of pancreatic lipases. On withdrawal of the high-fat diet, this inflamed adipose tissue fails to properly resolve, resulting in extensive fat necrosis. In terms of mechanisms, we show that adipose induction of FGF1 in the fed state is regulated by PPARgamma acting through an evolutionarily conserved promoter proximal PPAR response element within the FGF1 gene. The discovery of a phenotype for the FGF1 knockout mouse establishes the PPARgamma-FGF1 axis as critical for maintaining metabolic homeostasis and insulin sensitization.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3358516/" 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/PMC3358516/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jonker, Johan W -- Suh, Jae Myoung -- Atkins, Annette R -- Ahmadian, Maryam -- Li, Pingping -- Whyte, Jamie -- He, Mingxiao -- Juguilon, Henry -- Yin, Yun-Qiang -- Phillips, Colin T -- Yu, Ruth T -- Olefsky, Jerrold M -- Henry, Robert R -- Downes, Michael -- Evans, Ronald M -- DK057978/DK/NIDDK NIH HHS/ -- DK062434/DK/NIDDK NIH HHS/ -- DK063491/DK/NIDDK NIH HHS/ -- DK090962/DK/NIDDK NIH HHS/ -- HL105278/HL/NHLBI NIH HHS/ -- P30 CA014195/CA/NCI NIH HHS/ -- P30 DK063491/DK/NIDDK NIH HHS/ -- R01 DK033651/DK/NIDDK NIH HHS/ -- R01 HL105278/HL/NHLBI NIH HHS/ -- R01 HL105278-21/HL/NHLBI NIH HHS/ -- R24 DK090962/DK/NIDDK NIH HHS/ -- R24 DK090962-02/DK/NIDDK NIH HHS/ -- R37 DK033651/DK/NIDDK NIH HHS/ -- R37 DK057978/DK/NIDDK NIH HHS/ -- R37 DK057978-34/DK/NIDDK NIH HHS/ -- U19 DK062434/DK/NIDDK NIH HHS/ -- U19 DK062434-10/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 May 17;485(7398):391-4. doi: 10.1038/nature10998.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gene Expression Laboratory, Salk Institute for Biological Studies, 10010 North Torrey Pines Road, La Jolla, California 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22522926" target="_blank"〉PubMed〈/a〉

    A strong regional temperature signal in low-elevation Huon pine (2013)
    Wiley
    Details
    Publication Date: 2013-05-30
    Description: ABSTRACT We have produced the first annually resolved, centennial-length tree-ring chronologies, based on tracheid radial diameter (TRD) and microfibril angle for south-eastern Australia (SEA) from what would commonly be considered a dendroclimatically suboptimal site. The chronologies exhibit a strong regional temperature signal for the austral summer (nominally November–April) that extends across much of SEA. The strength and spatial extent of the temperature–TRD correlations surpass those between the iconic Tasmanian Mt Read ring-width chronology and austral summer temperatures, and are more time-stable. We demonstrate that the value of wood property chronologies for their ability to improve the both the quality and the quantity of highly climate-sensitive series available for regional annual-resolution climate reconstructions, in data-sparse regions in Australasia and beyond, should be examined. In light of the ‘divergence debate’, the time-stability of relationships with climate, relative to other tree-ring proxies, also requires further investigation.

    Notes: Abstract In trials conducted in a mushroom crop grown in commercial growing bags and inoculated with the dipteran pest,Lycoriella solani, and/or the predatory miteParasitus bituberosus, the mite reduced adult pest numbers ty 50–66%. It also reduced the numbers of larvalHeteropeza pygmaea, a second dipteran pest which occurred as a contaminant in one trial. Fewer mites were extracted towards the end of the cropping period. No evidence was found of an oscillating relationship between predator and prey over the trial period. Crop yield was increased by 18% and unsaleable yield was reduced by 50%. It is suggested that the mite can contribute to an integrated pest management system.

    Notes: Abstract The prey items accepted byParasitus bituberosus Karg included all immature instars ofHeteropeza pygmaea Winnertz, first and second instars ofLycoriella solani together with its eggs, and compost nematodes and springtails. A preference was shown by deutonymphs for first-instarH. pygmaea, whereasHistiostoma feroniarum andPygmephorus sp. were not accepted. Adult mites, especially females, appeared to be even more voracious predators on first-instarH. pygmaea than were deutonymphs or protonymphs. The mite preventedH. pygmaea from reaching high populations in both laboratory-scale and small commercial-scale compost units; it also reduced populations of free-living nematodes in the latter. The distributions ofH. pygmaea and the mite throughout the compost in growing-bags were investigated and found to parallel each other. The mite was able to penetrate all parts of the compost. There was no evidence that it damagedAgaricus bisporus, and it was never found on harvested caps.
