    Description: Pluripotency, the ability to generate any cell type of the body, is an evanescent attribute of embryonic cells. Transitory pluripotent cells can be captured at different time points during embryogenesis and maintained as embryonic stem cells or epiblast stem cells in culture. Since ontogenesis is a dynamic process in both space and time, it seems counterintuitive that these two temporal states represent the full spectrum of organismal pluripotency. Here we show that by modulating culture parameters, a stem-cell type with unique spatial characteristics and distinct molecular and functional features, designated as region-selective pluripotent stem cells (rsPSCs), can be efficiently obtained from mouse embryos and primate pluripotent stem cells, including humans. The ease of culturing and editing the genome of human rsPSCs offers advantages for regenerative medicine applications. The unique ability of human rsPSCs to generate post-implantation interspecies chimaeric embryos may facilitate our understanding of early human development and evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Jun -- Okamura, Daiji -- Li, Mo -- Suzuki, Keiichiro -- Luo, Chongyuan -- Ma, Li -- He, Yupeng -- Li, Zhongwei -- Benner, Chris -- Tamura, Isao -- Krause, Marie N -- Nery, Joseph R -- Du, Tingting -- Zhang, Zhuzhu -- Hishida, Tomoaki -- Takahashi, Yuta -- Aizawa, Emi -- Kim, Na Young -- Lajara, Jeronimo -- Guillen, Pedro -- Campistol, Josep M -- Esteban, Concepcion Rodriguez -- Ross, Pablo J -- Saghatelian, Alan -- Ren, Bing -- Ecker, Joseph R -- Izpisua Belmonte, Juan Carlos -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 May 21;521(7552):316-21. doi: 10.1038/nature14413.

    Description: Opioid receptor antagonists increase hyperalgesia in humans and animals, which indicates that endogenous activation of opioid receptors provides relief from acute pain; however, the mechanisms of long-term opioid inhibition of pathological pain have remained elusive. We found that tissue injury produced mu-opioid receptor (MOR) constitutive activity (MOR(CA)) that repressed spinal nociceptive signaling for months. Pharmacological blockade during the posthyperalgesia state with MOR inverse agonists reinstated central pain sensitization and precipitated hallmarks of opioid withdrawal (including adenosine 3',5'-monophosphate overshoot and hyperalgesia) that required N-methyl-D-aspartate receptor activation of adenylyl cyclase type 1. Thus, MOR(CA) initiates both analgesic signaling and a compensatory opponent process that generates endogenous opioid dependence. Tonic MOR(CA) suppression of withdrawal hyperalgesia may prevent the transition from acute to chronic pain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4440417/" 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/PMC4440417/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Corder, G -- Doolen, S -- Donahue, R R -- Winter, M K -- Jutras, B L -- He, Y -- Hu, X -- Wieskopf, J S -- Mogil, J S -- Storm, D R -- Wang, Z J -- McCarson, K E -- Taylor, B K -- 5K02DA19656/DA/NIDA NIH HHS/ -- F31 DA032496/DA/NIDA NIH HHS/ -- F31DA032496/DA/NIDA NIH HHS/ -- HD02528/HD/NICHD NIH HHS/ -- K02 DA019656/DA/NIDA NIH HHS/ -- P30 HD002528/HD/NICHD NIH HHS/ -- R01 NS045954/NS/NINDS NIH HHS/ -- R01NS45954/NS/NINDS NIH HHS/ -- UL1 TR000117/TR/NCATS NIH HHS/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1394-9. doi: 10.1126/science.1239403.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, University of Kentucky, Lexington, KY 40536, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24052307" 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: Understanding the diversity of human tissues is fundamental to disease and requires linking genetic information, which is identical in most of an individual's cells, with epigenetic mechanisms that could have tissue-specific roles. Surveys of DNA methylation in human tissues have established a complex landscape including both tissue-specific and invariant methylation patterns. Here we report high coverage methylomes that catalogue cytosine methylation in all contexts for the major human organ systems, integrated with matched transcriptomes and genomic sequence. By combining these diverse data types with each individuals' phased genome, we identified widespread tissue-specific differential CG methylation (mCG), partially methylated domains, allele-specific methylation and transcription, and the unexpected presence of non-CG methylation (mCH) in almost all human tissues. mCH correlated with tissue-specific functions, and using this mark, we made novel predictions of genes that escape X-chromosome inactivation in specific tissues. Overall, DNA methylation in several genomic contexts varies substantially among human tissues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4499021/" 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/PMC4499021/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schultz, Matthew D -- He, Yupeng -- Whitaker, John W -- Hariharan, Manoj -- Mukamel, Eran A -- Leung, Danny -- Rajagopal, Nisha -- Nery, Joseph R -- Urich, Mark A -- Chen, Huaming -- Lin, Shin -- Lin, Yiing -- Jung, Inkyung -- Schmitt, Anthony D -- Selvaraj, Siddarth -- Ren, Bing -- Sejnowski, Terrence J -- Wang, Wei -- Ecker, Joseph R -- F32 HL110473/HL/NHLBI NIH HHS/ -- F32HL110473/HL/NHLBI NIH HHS/ -- K99 HL119617/HL/NHLBI NIH HHS/ -- K99 NS080911/NS/NINDS NIH HHS/ -- K99HL119617/HL/NHLBI NIH HHS/ -- R00 NS080911/NS/NINDS NIH HHS/ -- R00NS080911/NS/NINDS NIH HHS/ -- R01 ES024984/ES/NIEHS NIH HHS/ -- T32 GM008666/GM/NIGMS NIH HHS/ -- U01 ES017166/ES/NIEHS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Jul 9;523(7559):212-6. doi: 10.1038/nature14465.
