    Patient-specific induced pluripotent stem-cell-derived models of LEOPARD syndrome (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-06-11
    Description: The generation of reprogrammed induced pluripotent stem cells (iPSCs) from patients with defined genetic disorders holds the promise of increased understanding of the aetiologies of complex diseases and may also facilitate the development of novel therapeutic interventions. We have generated iPSCs from patients with LEOPARD syndrome (an acronym formed from its main features; that is, lentigines, electrocardiographic abnormalities, ocular hypertelorism, pulmonary valve stenosis, abnormal genitalia, retardation of growth and deafness), an autosomal-dominant developmental disorder belonging to a relatively prevalent class of inherited RAS-mitogen-activated protein kinase signalling diseases, which also includes Noonan syndrome, with pleomorphic effects on several tissues and organ systems. The patient-derived cells have a mutation in the PTPN11 gene, which encodes the SHP2 phosphatase. The iPSCs have been extensively characterized and produce multiple differentiated cell lineages. A major disease phenotype in patients with LEOPARD syndrome is hypertrophic cardiomyopathy. We show that in vitro-derived cardiomyocytes from LEOPARD syndrome iPSCs are larger, have a higher degree of sarcomeric organization and preferential localization of NFATC4 in the nucleus when compared with cardiomyocytes derived from human embryonic stem cells or wild-type iPSCs derived from a healthy brother of one of the LEOPARD syndrome patients. These features correlate with a potential hypertrophic state. We also provide molecular insights into signalling pathways that may promote the disease phenotype.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2885001/" 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/PMC2885001/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carvajal-Vergara, Xonia -- Sevilla, Ana -- D'Souza, Sunita L -- Ang, Yen-Sin -- Schaniel, Christoph -- Lee, Dung-Fang -- Yang, Lei -- Kaplan, Aaron D -- Adler, Eric D -- Rozov, Roye -- Ge, Yongchao -- Cohen, Ninette -- Edelmann, Lisa J -- Chang, Betty -- Waghray, Avinash -- Su, Jie -- Pardo, Sherly -- Lichtenbelt, Klaske D -- Tartaglia, Marco -- Gelb, Bruce D -- Lemischka, Ihor R -- 5R01GM078465/GM/NIGMS NIH HHS/ -- R01 GM078465/GM/NIGMS NIH HHS/ -- R01 GM078465-03/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Jun 10;465(7299):808-12. doi: 10.1038/nature09005.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Gene and Cell Medicine, Black Family Stem Cell Institute, Mount Sinai School of Medicine, New York, New York 10029, USA. xcarvajal@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20535210" target="_blank"〉PubMed〈/a〉

    The growth factor progranulin binds to TNF receptors and is therapeutic against inflammatory arthritis in mice (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-03-12
    Description: The growth factor progranulin (PGRN) has been implicated in embryonic development, tissue repair, tumorigenesis, and inflammation, but its receptors remain unidentified. We report that PGRN bound directly to tumor necrosis factor receptors (TNFRs) and disturbed the TNFalpha-TNFR interaction. PGRN-deficient mice were susceptible to collagen-induced arthritis, and administration of PGRN reversed inflammatory arthritis. Atsttrin, an engineered protein composed of three PGRN fragments, exhibited selective TNFR binding. PGRN and Atsttrin prevented inflammation in multiple arthritis mouse models and inhibited TNFalpha-activated intracellular signaling. Collectively, these findings demonstrate that PGRN is a ligand of TNFR, an antagonist of TNFalpha signaling, and plays a critical role in the pathogenesis of inflammatory arthritis in mice. They also suggest new potential therapeutic interventions for various TNFalpha-mediated pathologies and conditions, including rheumatoid arthritis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3104397/" 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/PMC3104397/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Wei -- Lu, Yi -- Tian, Qing-Yun -- Zhang, Yan -- Guo, Feng-Jin -- Liu, Guang-Yi -- Syed, Nabeel Muzaffar -- Lai, Yongjie -- Lin, Edward Alan -- Kong, Li -- Su, Jeffrey -- Yin, Fangfang -- Ding, Ai-Hao -- Zanin-Zhorov, Alexandra -- Dustin, Michael L -- Tao, Jian -- Craft, Joseph -- Yin, Zhinan -- Feng, Jian Q -- Abramson, Steven B -- Yu, Xiu-Ping -- Liu, Chuan-ju -- AI43542/AI/NIAID NIH HHS/ -- AR040072/AR/NIAMS NIH HHS/ -- AR050620/AR/NIAMS NIH HHS/ -- AR053210/AR/NIAMS NIH HHS/ -- GM061710/GM/NIGMS NIH HHS/ -- R01 AI030165/AI/NIAID NIH HHS/ -- R01 AI030165-20/AI/NIAID NIH HHS/ -- R01 GM061710/GM/NIGMS NIH HHS/ -- R01 GM061710-08/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Apr 22;332(6028):478-84. doi: 10.1126/science.1199214.

    Notes: Six char samples generated from two coals were impregnated by solutions with different concentrations of Na2CO3 and /or K2CO3. The catalyst solution penetration was studied, the catalyst uptake was measured, and the effects of impregnation on the char pore structure were determined experimentally. The results indicate that the impregnated catalysts reside only on particle exteriors without significant penetration. The overall rate of reaction is therfore the combination of catalytic reaction on particle exteriors and noncatalytic reaction on the pore surfaces inside the particle. A kinetic model is presented that takes these findings into account.

    Notes: Oxidation rates of Na2CO3- and K2CO3-impregnated char samples were measured in an isothermal kinetic control regime. The results were analyzed by a previously developed model to extract the intrinsic catalytic reactivities, freed from superimposed noncatalytic and structural effects. Although the overall catalyzed rates are only several times greater than their uncatalyzed counterparts, the intrinsic catalytic rates were found to be four orders of magnitude greater. The results further indicate that the function of the catalyst is to increase the number of active sites without affecting the activation energy. The overall reaction kinetics are demonstrated to contain the combined contributions of both catalytic and noncatalytic reactions, and in this context the effects of multiple catalysts as well as of the pore structure development during reaction can be understood and interpreted.

    Notes: Prior studies have demonstrated that char gasification rates vary with conversion, showing a maximum at an intermediate level. In this work experimentally determined char-air reaction rates and corresponding pore structures are compared to assess the applicability of a previously proposed random pore model and to extract pertinent chemical and physical parameters. Results on six different chars are presented and analyzed to obtain structure parameters, intrinsic kinetics, and activation energies. Agreement between two independent evaluations of the structure parameters demonstrates the degree of applicability of the random pore model and supports the view that rate variations with conversion are controlled by pore structural changes, even though overall rates also include contributions of intrinsic reactivity.

    Notes: The ferroelectric and piezoelectric properties of a new class of polymer ferroelectric and piezoelectric materials, nylon 11/polyvinylidene fluoride (PVF2) bilaminate films, prepared by a co-melt-pressing method, is presented. The bilaminate films exhibit typical ferroelectric D-E hysteresis behavior with a remanent polarization, Pr, of about 75 mC/m2, which is higher than the value of 52 mC/m2 observed for PVF2 or nylon 11 films measured under the same conditions. The coercive field, Ec, of the bilaminate films is ∼ 78 MV/m, which is higher than that of either PVF2 or nylon 11 films. Measurements of the temperature dependence of the piezoelectric strain coefficient, d31, and the piezoelectric stress coefficient, e31, were also carried out. The bilaminate films exhibit a piezoelectric strain coefficient, d31, of 41 pC/N at room temperature, which is significantly higher than the PVF2 films (25 pC/N) and the nylon 11 films (3.1 pC/N). When the temperature is increased to 110°C, d31 of the bilaminate films reaches a maximum value of 63 pC/N, more than five times that of PVF2 (11 pC/N) and more than four times that of nylon 11 (14 pC/N) at the same temperature. The piezoelectric stress coefficient, e31, of the bilaminate films shows a value of 109 mC/m2 at room temperature, almost twice that of the PVF2 films (59 mC/m2) and about 18 times that of the nylon 11 films (6.2 mC/m2). Measurement of the temperature dependence of the hydrostatic piezoelectric coefficient, dh, of the bilaminate films also shows an enhancement with respect to the individual components, PVF2 and nylon 11. ©1995 John Wiley & Sons, Inc.
