    Description: Obesity induced in mice by high-fat feeding activates the protein kinase Cdk5 (cyclin-dependent kinase 5) in adipose tissues. This results in phosphorylation of the nuclear receptor PPARgamma (peroxisome proliferator-activated receptor gamma), a dominant regulator of adipogenesis and fat cell gene expression, at serine 273. This modification of PPARgamma does not alter its adipogenic capacity, but leads to dysregulation of a large number of genes whose expression is altered in obesity, including a reduction in the expression of the insulin-sensitizing adipokine, adiponectin. The phosphorylation of PPARgamma by Cdk5 is blocked by anti-diabetic PPARgamma ligands, such as rosiglitazone and MRL24. This inhibition works both in vivo and in vitro, and is completely independent of classical receptor transcriptional agonism. Similarly, inhibition of PPARgamma phosphorylation in obese patients by rosiglitazone is very tightly associated with the anti-diabetic effects of this drug. All these findings strongly suggest that Cdk5-mediated phosphorylation of PPARgamma may be involved in the pathogenesis of insulin-resistance, and present an opportunity for development of an improved generation of anti-diabetic drugs through PPARgamma.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2987584/" 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/PMC2987584/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi, Jang Hyun -- Banks, Alexander S -- Estall, Jennifer L -- Kajimura, Shingo -- Bostrom, Pontus -- Laznik, Dina -- Ruas, Jorge L -- Chalmers, Michael J -- Kamenecka, Theodore M -- Bluher, Matthias -- Griffin, Patrick R -- Spiegelman, Bruce M -- DK087853/DK/NIDDK NIH HHS/ -- DK31405/DK/NIDDK NIH HHS/ -- K99 DK087853/DK/NIDDK NIH HHS/ -- R01 GM084041/GM/NIGMS NIH HHS/ -- R01 GM084041-03/GM/NIGMS NIH HHS/ -- R01-GM084041/GM/NIGMS NIH HHS/ -- R37 DK031405/DK/NIDDK NIH HHS/ -- R37 DK031405-30/DK/NIDDK NIH HHS/ -- S10 RR027270/RR/NCRR NIH HHS/ -- U54 MH084512/MH/NIMH NIH HHS/ -- U54 MH084512-020010/MH/NIMH NIH HHS/ -- U54-MH084512/MH/NIMH NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2010 Jul 22;466(7305):451-6. doi: 10.1038/nature09291.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology and Division of Metabolism and Chronic Disease, Dana-Farber Cancer Institute, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20651683" target="_blank"〉PubMed〈/a〉

    Description: PPARgamma is the functioning receptor for the thiazolidinedione (TZD) class of antidiabetes drugs including rosiglitazone and pioglitazone. These drugs are full classical agonists for this nuclear receptor, but recent data have shown that many PPARgamma-based drugs have a separate biochemical activity, blocking the obesity-linked phosphorylation of PPARgamma by Cdk5. Here we describe novel synthetic compounds that have a unique mode of binding to PPARgamma, completely lack classical transcriptional agonism and block the Cdk5-mediated phosphorylation in cultured adipocytes and in insulin-resistant mice. Moreover, one such compound, SR1664, has potent antidiabetic activity while not causing the fluid retention and weight gain that are serious side effects of many of the PPARgamma drugs. Unlike TZDs, SR1664 also does not interfere with bone formation in culture. These data illustrate that new classes of antidiabetes drugs can be developed by specifically targeting the Cdk5-mediated phosphorylation of PPARgamma.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3179551/" 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/PMC3179551/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Choi, Jang Hyun -- Banks, Alexander S -- Kamenecka, Theodore M -- Busby, Scott A -- Chalmers, Michael J -- Kumar, Naresh -- Kuruvilla, Dana S -- Shin, Youseung -- He, Yuanjun -- Bruning, John B -- Marciano, David P -- Cameron, Michael D -- Laznik, Dina -- Jurczak, Michael J -- Schurer, Stephan C -- Vidovic, Dusica -- Shulman, Gerald I -- Spiegelman, Bruce M -- Griffin, Patrick R -- 1RC4DK090861/DK/NIDDK NIH HHS/ -- DK31405/DK/NIDDK NIH HHS/ -- R01 DK040936/DK/NIDDK NIH HHS/ -- R01 GM084041/GM/NIGMS NIH HHS/ -- R01 GM084041-03/GM/NIGMS NIH HHS/ -- R01-GM084041/GM/NIGMS NIH HHS/ -- R37 DK031405/DK/NIDDK NIH HHS/ -- R37 DK031405-30/DK/NIDDK NIH HHS/ -- R37 DK031405-31/DK/NIDDK NIH HHS/ -- RC4 DK090861/DK/NIDDK NIH HHS/ -- RC4 DK090861-01/DK/NIDDK NIH HHS/ -- S10 RR027270/RR/NCRR NIH HHS/ -- U24 DK059635/DK/NIDDK NIH HHS/ -- U54 MH074404/MH/NIMH NIH HHS/ -- U54 MH074404-01/MH/NIMH NIH HHS/ -- U54-MH074404/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- England -- Nature. 2011 Sep 4;477(7365):477-81. doi: 10.1038/nature10383.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology and Division of Metabolism and Chronic Disease, Dana-Farber Cancer Institute and Department of Cell Biology, Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21892191" target="_blank"〉PubMed〈/a〉

    Description: Exercise benefits a variety of organ systems in mammals, and some of the best-recognized effects of exercise on muscle are mediated by the transcriptional co-activator PPAR-gamma co-activator-1 alpha (PGC1-alpha). Here we show in mouse that PGC1-alpha expression in muscle stimulates an increase in expression of FNDC5, a membrane protein that is cleaved and secreted as a newly identified hormone, irisin. Irisin acts on white adipose cells in culture and in vivo to stimulate UCP1 expression and a broad program of brown-fat-like development. Irisin is induced with exercise in mice and humans, and mildly increased irisin levels in the blood cause an increase in energy expenditure in mice with no changes in movement or food intake. This results in improvements in obesity and glucose homeostasis. Irisin could be therapeutic for human metabolic disease and other disorders that are improved with exercise.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3522098/" 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/PMC3522098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bostrom, Pontus -- Wu, Jun -- Jedrychowski, Mark P -- Korde, Anisha -- Ye, Li -- Lo, James C -- Rasbach, Kyle A -- Bostrom, Elisabeth Almer -- Choi, Jang Hyun -- Long, Jonathan Z -- Kajimura, Shingo -- Zingaretti, Maria Cristina -- Vind, Birgitte F -- Tu, Hua -- Cinti, Saverio -- Hojlund, Kurt -- Gygi, Steven P -- Spiegelman, Bruce M -- DK31405/DK/NIDDK NIH HHS/ -- DK54477/DK/NIDDK NIH HHS/ -- K99 DK087853/DK/NIDDK NIH HHS/ -- R01 DK054477/DK/NIDDK NIH HHS/ -- R01 DK061562/DK/NIDDK NIH HHS/ -- R37 DK031405/DK/NIDDK NIH HHS/ -- England -- Nature. 2012 Jan 11;481(7382):463-8. doi: 10.1038/nature10777.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22237023" target="_blank"〉PubMed〈/a〉

    Notes: Summary Pseudomonas 135, a facultative methylotroph, was cultivated on methanol as a sole carbon and energy source for the accumulation of poly-β-hydroxybutyric acid (PHB). The cells grew fairly well on minimal synthetic medium containing 0.5% (v/v) of methanol at pH 7.0 and 30° C. The maximum specific growth rate was determined to be 0.26–0.28 h−1 with a growth yield of 0.38 in the optimized growth medium. For stimulation of PHB accumulation in the cells, deficiency of nutrients such as NH inf4 sup+ , Mg2+ and PO inf4 sup3− was crucial even though cell growth was significantly suppressed. The PHB content of a 40-h culture was determined to be 37% of the total cell mass in NH inf4 sup+ -limited medium, 42.5% on Mg2+-deficient medium, and 34.5% on PO inf4 sup3− -deficient medium. The maximum content of PHB in the cells could reach 55% in NH inf4 sup+ -limited fed-batch culture. The average relative molecular eight determined by gel permeation chromatography was 3.7 × 105 in NH inf4 sup+ -limited culture, 2.5 × 105 in Mg2+-deficientmedium, and 3.1 × 105 in PO inf4 sup3− -deficient medium. Polydispersity determined in each culture was relatively high (about 10–11). The solid PHB had a melting temperature of 173° C.

    Notes: Abstract Although many studies have examined the influence of culture conditions on the production and composition of polysaccharides, little is known about the factors influencing the quality of exopolysaccharides (EPS). In this work we studied the effect of yeast extract on the production, composition and molecular weight of the EPS zooglan produced by Zoogloea ramigera 115SLR. This bacterium was grown on a new completely defined synthetic medium and on a medium containing yeast extract. Growth and polysaccharide production performances were comparable on the two media with a glucose to exopolysaccharide conversion yield of 35% (g/g). The polysaccharides produced on these two media have an identical composition but a different molecular weight and molecular weight distribution. The yeast extract medium leads to a more homogeneous polysaccharide solution.
