    An internal thermal sensor controlling temperature preference in Drosophila (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-06-13
    Description: Animals from flies to humans are able to distinguish subtle gradations in temperature and show strong temperature preferences. Animals move to environments of optimal temperature and some manipulate the temperature of their surroundings, as humans do using clothing and shelter. Despite the ubiquitous influence of environmental temperature on animal behaviour, the neural circuits and strategies through which animals select a preferred temperature remain largely unknown. Here we identify a small set of warmth-activated anterior cell (AC) neurons located in the Drosophila brain, the function of which is critical for preferred temperature selection. AC neuron activation occurs just above the fly's preferred temperature and depends on dTrpA1, an ion channel that functions as a molecular sensor of warmth. Flies that selectively express dTrpA1 in the AC neurons select normal temperatures, whereas flies in which dTrpA1 function is reduced or eliminated choose warmer temperatures. This internal warmth-sensing pathway promotes avoidance of slightly elevated temperatures and acts together with a distinct pathway for cold avoidance to set the fly's preferred temperature. Thus, flies select a preferred temperature by using a thermal sensing pathway tuned to trigger avoidance of temperatures that deviate even slightly from the preferred temperature. This provides a potentially general strategy for robustly selecting a narrow temperature range optimal for survival.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2730888/" 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/PMC2730888/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hamada, Fumika N -- Rosenzweig, Mark -- Kang, Kyeongjin -- Pulver, Stefan R -- Ghezzi, Alfredo -- Jegla, Timothy J -- Garrity, Paul A -- P01 NS044232/NS/NINDS NIH HHS/ -- P01 NS044232-060002/NS/NINDS NIH HHS/ -- P01 NS044232-070002/NS/NINDS NIH HHS/ -- P30 NS045713/NS/NINDS NIH HHS/ -- P30 NS045713-069006/NS/NINDS NIH HHS/ -- P30 NS045713S10/NS/NINDS NIH HHS/ -- R01 EY013874/EY/NEI NIH HHS/ -- R01 EY013874-06/EY/NEI NIH HHS/ -- R01 EY13874/EY/NEI NIH HHS/ -- R01 MH067284/MH/NIMH NIH HHS/ -- R01 MH067284-05/MH/NIMH NIH HHS/ -- RR16780/RR/NCRR NIH HHS/ -- England -- Nature. 2008 Jul 10;454(7201):217-20. doi: 10.1038/nature07001.

    Attributing physical and biological impacts to anthropogenic climate change (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-05-16
    Description: Significant changes in physical and biological systems are occurring on all continents and in most oceans, with a concentration of available data in Europe and North America. Most of these changes are in the direction expected with warming temperature. Here we show that these changes in natural systems since at least 1970 are occurring in regions of observed temperature increases, and that these temperature increases at continental scales cannot be explained by natural climate variations alone. Given the conclusions from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report that most of the observed increase in global average temperatures since the mid-twentieth century is very likely to be due to the observed increase in anthropogenic greenhouse gas concentrations, and furthermore that it is likely that there has been significant anthropogenic warming over the past 50 years averaged over each continent except Antarctica, we conclude that anthropogenic climate change is having a significant impact on physical and biological systems globally and in some continents.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosenzweig, Cynthia -- Karoly, David -- Vicarelli, Marta -- Neofotis, Peter -- Wu, Qigang -- Casassa, Gino -- Menzel, Annette -- Root, Terry L -- Estrella, Nicole -- Seguin, Bernard -- Tryjanowski, Piotr -- Liu, Chunzhen -- Rawlins, Samuel -- Imeson, Anton -- England -- Nature. 2008 May 15;453(7193):353-7. doi: 10.1038/nature06937.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉NASA/Goddard Institute for Space Studies and Columbia Center for Climate Systems Research, 2800 Broadway, New York, New York 10025, USA. crosenzweig@giss.nasa.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18480817" target="_blank"〉PubMed〈/a〉

    HIF-independent regulation of VEGF and angiogenesis by the transcriptional coactivator PGC-1alpha (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-02-22
    Description: Ischaemia of the heart, brain and limbs is a leading cause of morbidity and mortality worldwide. Hypoxia stimulates the secretion of vascular endothelial growth factor (VEGF) and other angiogenic factors, leading to neovascularization and protection against ischaemic injury. Here we show that the transcriptional coactivator PGC-1alpha (peroxisome-proliferator-activated receptor-gamma coactivator-1alpha), a potent metabolic sensor and regulator, is induced by a lack of nutrients and oxygen, and PGC-1alpha powerfully regulates VEGF expression and angiogenesis in cultured muscle cells and skeletal muscle in vivo. PGC-1alpha-/- mice show a striking failure to reconstitute blood flow in a normal manner to the limb after an ischaemic insult, whereas transgenic expression of PGC-1alpha in skeletal muscle is protective. Surprisingly, the induction of VEGF by PGC-1alpha does not involve the canonical hypoxia response pathway and hypoxia inducible factor (HIF). Instead, PGC-1alpha coactivates the orphan nuclear receptor ERR-alpha (oestrogen-related receptor-alpha) on conserved binding sites found in the promoter and in a cluster within the first intron of the VEGF gene. Thus, PGC-1alpha and ERR-alpha, major regulators of mitochondrial function in response to exercise and other stimuli, also control a novel angiogenic pathway that delivers needed oxygen and substrates. PGC-1alpha may provide a novel therapeutic target for treating ischaemic diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arany, Zoltan -- Foo, Shi-Yin -- Ma, Yanhong -- Ruas, Jorge L -- Bommi-Reddy, Archana -- Girnun, Geoffrey -- Cooper, Marcus -- Laznik, Dina -- Chinsomboon, Jessica -- Rangwala, Shamina M -- Baek, Kwan Hyuck -- Rosenzweig, Anthony -- Spiegelman, Bruce M -- P30 DK040561/DK/NIDDK NIH HHS/ -- P30 DK040561-12/DK/NIDDK NIH HHS/ -- R01 DK054477/DK/NIDDK NIH HHS/ -- England -- Nature. 2008 Feb 21;451(7181):1008-12. doi: 10.1038/nature06613.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute and Department of Cell Biology, Harvard Medical School, Boston, Massachusetts 02115, USA. zarany1@partners.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18288196" target="_blank"〉PubMed〈/a〉

    Oxidation of methane by a biological dicopper centre (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-04-23
    Description: Vast world reserves of methane gas are underutilized as a feedstock for the production of liquid fuels and chemicals owing to the lack of economical and sustainable strategies for the selective oxidation of methane to methanol. Current processes to activate the strong C-H bond (104 kcal mol(-1)) in methane require high temperatures, are costly and inefficient, and produce waste. In nature, methanotrophic bacteria perform this reaction under ambient conditions using metalloenzymes called methane monooxygenases (MMOs). MMOs thus provide the optimal model for an efficient, environmentally sound catalyst. There are two types of MMO. Soluble MMO (sMMO) is expressed by several strains of methanotroph under copper-limited conditions and oxidizes methane with a well-characterized catalytic di-iron centre. Particulate MMO (pMMO) is an integral membrane metalloenzyme produced by all methanotrophs and is composed of three subunits, pmoA, pmoB and pmoC, arranged in a trimeric alpha(3)beta(3)gamma(3) complex. Despite 20 years of research and the availability of two crystal structures, the metal composition and location of the pMMO metal active site are not known. Here we show that pMMO activity is dependent on copper, not iron, and that the copper active site is located in the soluble domains of the pmoB subunit rather than within the membrane. Recombinant soluble fragments of pmoB (spmoB) bind copper and have propylene and methane oxidation activities. Disruption of each copper centre in spmoB by mutagenesis indicates that the active site is a dicopper centre. These findings help resolve the pMMO controversy and provide a promising new approach to developing environmentally friendly C-H oxidation catalysts.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2999467/" 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/PMC2999467/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Balasubramanian, Ramakrishnan -- Smith, Stephen M -- Rawat, Swati -- Yatsunyk, Liliya A -- Stemmler, Timothy L -- Rosenzweig, Amy C -- DK068139/DK/NIDDK NIH HHS/ -- GM070473/GM/NIGMS NIH HHS/ -- R01 DK068139/DK/NIDDK NIH HHS/ -- R01 DK068139-05/DK/NIDDK NIH HHS/ -- R01 GM070473/GM/NIGMS NIH HHS/ -- R01 GM070473-07/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 May 6;465(7294):115-9. doi: 10.1038/nature08992.
