    Description: Matrix metalloproteinases (MMPs) are implicated in the pathogenesis of neurodegenerative diseases and stroke. However, the mechanism of MMP activation remains unclear. We report that MMP activation involves S-nitrosylation. During cerebral ischemia in vivo, MMP-9 colocalized with neuronal nitric oxide synthase. S-Nitrosylation activated MMP-9 in vitro and induced neuronal apoptosis. Mass spectrometry identified the active derivative of MMP-9, both in vitro and in vivo, as a stable sulfinic or sulfonic acid, whose formation was triggered by S-nitrosylation. These findings suggest a potential extracellular proteolysis pathway to neuronal cell death in which S-nitrosylation activates MMPs, and further oxidation results in a stable posttranslational modification with pathological activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Zezong -- Kaul, Marcus -- Yan, Boxu -- Kridel, Steven J -- Cui, Jiankun -- Strongin, Alex -- Smith, Jeffrey W -- Liddington, Robert C -- Lipton, Stuart A -- AR08505/AR/NIAMS NIH HHS/ -- P01 HD29587/HD/NICHD NIH HHS/ -- R01 AR42750/AR/NIAMS NIH HHS/ -- R01 CA 69306/CA/NCI NIH HHS/ -- R01 EY05477/EY/NEI NIH HHS/ -- R01 EY09024/EY/NEI NIH HHS/ -- R01 NS41207/NS/NINDS NIH HHS/ -- T32 AG00252/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 16;297(5584):1186-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience and Aging, Program in Cell Adhesion and Extracellular Matrix Biology, The Burnham Institute, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12183632" target="_blank"〉PubMed〈/a〉

    Description: The adipose-derived hormone leptin maintains energy balance in part through central nervous system-mediated increases in sympathetic outflow that enhance fat burning. Triggering of beta-adrenergic receptors in adipocytes stimulates energy expenditure by cyclic AMP (cAMP)-dependent increases in lipolysis and fatty-acid oxidation. Although the mechanism is unclear, catecholamine signalling is thought to be disrupted in obesity, leading to the development of insulin resistance. Here we show that the cAMP response element binding (CREB) coactivator Crtc3 promotes obesity by attenuating beta-adrenergic receptor signalling in adipose tissue. Crtc3 was activated in response to catecholamine signals, when it reduced adenyl cyclase activity by upregulating the expression of Rgs2, a GTPase-activating protein that also inhibits adenyl cyclase activity. As a common human CRTC3 variant with increased transcriptional activity is associated with adiposity in two distinct Mexican-American cohorts, these results suggest that adipocyte CRTC3 may play a role in the development of obesity in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3025711/" 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/PMC3025711/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Youngsup -- Altarejos, Judith -- Goodarzi, Mark O -- Inoue, Hiroshi -- Guo, Xiuqing -- Berdeaux, Rebecca -- Kim, Jeong-Ho -- Goode, Jason -- Igata, Motoyuki -- Paz, Jose C -- Hogan, Meghan F -- Singh, Pankaj K -- Goebel, Naomi -- Vera, Lili -- Miller, Nina -- Cui, Jinrui -- Jones, Michelle R -- CHARGE Consortium -- GIANT Consortium -- Chen, Yii-Der I -- Taylor, Kent D -- Hsueh, Willa A -- Rotter, Jerome I -- Montminy, Marc -- M01 RR000425-36/RR/NCRR NIH HHS/ -- M01-RR00425/RR/NCRR NIH HHS/ -- N01 HC095159/HC/NHLBI NIH HHS/ -- N01-HC95159/HC/NHLBI NIH HHS/ -- N02 HL64278/HL/NHLBI NIH HHS/ -- N02-HL64278/HL/NHLBI NIH HHS/ -- P30 DK063491/DK/NIDDK NIH HHS/ -- P30 DK063491-09/DK/NIDDK NIH HHS/ -- P30-DK063491/DK/NIDDK NIH HHS/ -- R01 DK033651/DK/NIDDK NIH HHS/ -- R01 DK049777/DK/NIDDK NIH HHS/ -- R01 DK049777-18/DK/NIDDK NIH HHS/ -- R01 DK079888/DK/NIDDK NIH HHS/ -- R01 DK079888-05/DK/NIDDK NIH HHS/ -- R01 HL071205/HL/NHLBI NIH HHS/ -- R01 HL071205-05/HL/NHLBI NIH HHS/ -- R01 HL088457/HL/NHLBI NIH HHS/ -- R01 HL088457-04/HL/NHLBI NIH HHS/ -- R01-DK049777/DK/NIDDK NIH HHS/ -- R01-DK083834/DK/NIDDK NIH HHS/ -- R01-DK79888/DK/NIDDK NIH HHS/ -- R01-HL088457/HL/NHLBI NIH HHS/ -- R01-L071205/PHS HHS/ -- R37 DK083834/DK/NIDDK NIH HHS/ -- R37 DK083834-26/DK/NIDDK NIH HHS/ -- R37 DK083834-27/DK/NIDDK NIH HHS/ -- England -- Nature. 2010 Dec 16;468(7326):933-9. doi: 10.1038/nature09564.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The 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/21164481" target="_blank"〉PubMed〈/a〉

    Description: A family of bacterial effectors including Cif homolog from Burkholderia pseudomallei (CHBP) and Cif from Enteropathogenic Escherichia coli (EPEC) adopt a functionally important papain-like hydrolytic fold. We show here that CHBP was a potent inhibitor of the eukaryotic ubiquitination pathway. CHBP acted as a deamidase that specifically and efficiently deamidated Gln40 in ubiquitin and ubiquitin-like protein NEDD8 both in vitro and during Burkholderia infection. Deamidated ubiquitin was impaired in supporting ubiquitin-chain synthesis. Cif selectively deamidated NEDD8, which abolished the activity of neddylated Cullin-RING ubiquitin ligases (CRLs). Ubiquitination and ubiquitin-dependent degradation of multiple CRL substrates were impaired by Cif in EPEC-infected cells. Mutations of substrate-contacting residues in Cif abolished or attenuated EPEC-induced cytopathic phenotypes of cell cycle arrest and actin stress fiber formation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3031172/" 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/PMC3031172/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cui, Jixin -- Yao, Qing -- Li, Shan -- Ding, Xiaojun -- Lu, Qiuhe -- Mao, Haibin -- Liu, Liping -- Zheng, Ning -- Chen, She -- Shao, Feng -- R01 CA107134/CA/NCI NIH HHS/ -- R01 CA107134-08/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Sep 3;329(5996):1215-8. doi: 10.1126/science.1193844.

    Description: A major challenge in human genetics is to devise a systematic strategy to integrate disease-associated variants with diverse genomic and biological data sets to provide insight into disease pathogenesis and guide drug discovery for complex traits such as rheumatoid arthritis (RA). Here we performed a genome-wide association study meta-analysis in a total of 〉100,000 subjects of European and Asian ancestries (29,880 RA cases and 73,758 controls), by evaluating approximately 10 million single-nucleotide polymorphisms. We discovered 42 novel RA risk loci at a genome-wide level of significance, bringing the total to 101 (refs 2 - 4). We devised an in silico pipeline using established bioinformatics methods based on functional annotation, cis-acting expression quantitative trait loci and pathway analyses--as well as novel methods based on genetic overlap with human primary immunodeficiency, haematological cancer somatic mutations and knockout mouse phenotypes--to identify 98 biological candidate genes at these 101 risk loci. We demonstrate that these genes are the targets of approved therapies for RA, and further suggest that drugs approved for other indications may be repurposed for the treatment of RA. Together, this comprehensive genetic study sheds light on fundamental genes, pathways and cell types that contribute to RA pathogenesis, and provides empirical evidence that the genetics of RA can provide important information for drug discovery.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3944098/" 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/PMC3944098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okada, Yukinori -- Wu, Di -- Trynka, Gosia -- Raj, Towfique -- Terao, Chikashi -- Ikari, Katsunori -- Kochi, Yuta -- Ohmura, Koichiro -- Suzuki, Akari -- Yoshida, Shinji -- Graham, Robert R -- Manoharan, Arun -- Ortmann, Ward -- Bhangale, Tushar -- Denny, Joshua C -- Carroll, Robert J -- Eyler, Anne E -- Greenberg, Jeffrey D -- Kremer, Joel M -- Pappas, Dimitrios A -- Jiang, Lei -- Yin, Jian -- Ye, Lingying -- Su, Ding-Feng -- Yang, Jian -- Xie, Gang -- Keystone, Ed -- Westra, Harm-Jan -- Esko, Tonu -- Metspalu, Andres -- Zhou, Xuezhong -- Gupta, Namrata -- Mirel, Daniel -- Stahl, Eli A -- Diogo, Dorothee -- Cui, Jing -- Liao, Katherine -- Guo, Michael H -- Myouzen, Keiko -- Kawaguchi, Takahisa -- Coenen, Marieke J H -- van Riel, Piet L C M -- van de Laar, Mart A F J -- Guchelaar, Henk-Jan -- Huizinga, Tom W J -- Dieude, Philippe -- Mariette, Xavier -- Bridges, S Louis Jr -- Zhernakova, Alexandra -- Toes, Rene E M -- Tak, Paul P -- Miceli-Richard, Corinne -- Bang, So-Young -- Lee, Hye-Soon -- Martin, Javier -- Gonzalez-Gay, Miguel A -- Rodriguez-Rodriguez, Luis -- Rantapaa-Dahlqvist, Solbritt -- Arlestig, Lisbeth -- Choi, Hyon K -- Kamatani, Yoichiro -- Galan, Pilar -- Lathrop, Mark -- RACI consortium -- GARNET consortium -- Eyre, Steve -- Bowes, John -- Barton, Anne -- de Vries, Niek -- Moreland, Larry W -- Criswell, Lindsey A -- Karlson, Elizabeth W -- Taniguchi, Atsuo -- Yamada, Ryo -- Kubo, Michiaki -- Liu, Jun S -- Bae, Sang-Cheol -- Worthington, Jane -- Padyukov, Leonid -- Klareskog, Lars -- Gregersen, Peter K -- Raychaudhuri, Soumya -- Stranger, Barbara E -- De Jager, Philip L -- Franke, Lude -- Visscher, Peter M -- Brown, Matthew A -- Yamanaka, Hisashi -- Mimori, Tsuneyo -- Takahashi, Atsushi -- Xu, Huji -- Behrens, Timothy W -- Siminovitch, Katherine A -- Momohara, Shigeki -- Matsuda, Fumihiko -- Yamamoto, Kazuhiko -- Plenge, Robert M -- 20385/Arthritis Research UK/United Kingdom -- 79321/Canadian Institutes of Health Research/Canada -- K08-KAR055688A/PHS HHS/ -- K24 AR052403/AR/NIAMS NIH HHS/ -- P60 AR047785/AR/NIAMS NIH HHS/ -- R01 AR056768/AR/NIAMS NIH HHS/ -- R01 AR057108/AR/NIAMS NIH HHS/ -- R01 AR059648/AR/NIAMS NIH HHS/ -- R01 AR063759/AR/NIAMS NIH HHS/ -- R01-AR056291/AR/NIAMS NIH HHS/ -- R01-AR056768/AR/NIAMS NIH HHS/ -- R01-AR057108/AR/NIAMS NIH HHS/ -- R01-AR059648/AR/NIAMS NIH HHS/ -- R01-AR065944/AR/NIAMS NIH HHS/ -- R01AR063759-01A1/AR/NIAMS NIH HHS/ -- R21 AR056042/AR/NIAMS NIH HHS/ -- T15 LM007450/LM/NLM NIH HHS/ -- U01 GM092691/GM/NIGMS NIH HHS/ -- U01-GM092691/GM/NIGMS NIH HHS/ -- U19 HL065962/HL/NHLBI NIH HHS/ -- England -- Nature. 2014 Feb 20;506(7488):376-81. doi: 10.1038/nature12873.

    Description: NF-kappaB is crucial for innate immune defence against microbial infection. Inhibition of NF-kappaB signalling has been observed with various bacterial infections. The NF-kappaB pathway critically requires multiple ubiquitin-chain signals of different natures. The question of whether ubiquitin-chain signalling and its specificity in NF-kappaB activation are regulated during infection, and how this regulation takes place, has not been explored. Here we show that human TAB2 and TAB3, ubiquitin-chain sensory proteins involved in NF-kappaB signalling, are directly inactivated by enteropathogenic Escherichia coli NleE, a conserved bacterial type-III-secreted effector responsible for blocking host NF-kappaB signalling. NleE harboured an unprecedented S-adenosyl-l-methionine-dependent methyltransferase activity that specifically modified a zinc-coordinating cysteine in the Npl4 zinc finger (NZF) domains in TAB2 and TAB3. Cysteine-methylated TAB2-NZF and TAB3-NZF (truncated proteins only comprising the NZF domain) lost the zinc ion as well as the ubiquitin-chain binding activity. Ectopically expressed or type-III-secretion-system-delivered NleE methylated TAB2 and TAB3 in host cells and diminished their ubiquitin-chain binding activity. Replacement of the NZF domain of TAB3 with the NleE methylation-insensitive Npl4 NZF domain resulted in NleE-resistant NF-kappaB activation. Given the prevalence of zinc-finger motifs and activation of cysteine thiol by zinc binding, methylation of zinc-finger cysteine might regulate other eukaryotic pathways in addition to NF-kappaB signalling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Li -- Ding, Xiaojun -- Cui, Jixin -- Xu, Hao -- Chen, Jing -- Gong, Yi-Nan -- Hu, Liyan -- Zhou, Yan -- Ge, Jianning -- Lu, Qiuhe -- Liu, Liping -- Chen, She -- Shao, Feng -- England -- Nature. 2011 Dec 11;481(7380):204-8. doi: 10.1038/nature10690.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Program in Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22158122" target="_blank"〉PubMed〈/a〉
