    Role of IQGAP1, a target of the small GTPases Cdc42 and Rac1, in regulation of E-cadherin- mediated cell-cell adhesion (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-08-07
    Description: The small guanosine triphosphatases (GTPases) Cdc42 and Rac1 regulate E-cadherin-mediated cell-cell adhesion. IQGAP1, a target of Cdc42 and Rac1, was localized with E-cadherin and beta-catenin at sites of cell-cell contact in mouse L fibroblasts expressing E-cadherin (EL cells), and interacted with E-cadherin and beta-catenin both in vivo and in vitro. IQGAP1 induced the dissociation of alpha-catenin from a cadherin-catenin complex in vitro and in vivo. Overexpression of IQGAP1 in EL cells, but not in L cells expressing an E-cadherin-alpha-catenin chimeric protein, resulted in a decrease in E-cadherin-mediated cell-cell adhesive activity. Thus, IQGAP1, acting downstream of Cdc42 and Rac1, appears to regulate cell-cell adhesion through the cadherin-catenin pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuroda, S -- Fukata, M -- Nakagawa, M -- Fujii, K -- Nakamura, T -- Ookubo, T -- Izawa, I -- Nagase, T -- Nomura, N -- Tani, H -- Shoji, I -- Matsuura, Y -- Yonehara, S -- Kaibuchi, K -- New York, N.Y. -- Science. 1998 Aug 7;281(5378):832-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Nara Institute of Science and Technology, Ikoma 630-0101, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9694656" target="_blank"〉PubMed〈/a〉

    Formation of actin stress fibers and focal adhesions enhanced by Rho-kinase (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-02-28
    Description: The small guanosine triphosphatase (GTPase) Rho is implicated in the formation of stress fibers and focal adhesions in fibroblasts stimulated by extracellular signals such as lysophosphatidic acid (LPA). Rho-kinase is activated by Rho and may mediate some biological effects of Rho. Microinjection of the catalytic domain of Rho-kinase into serum-starved Swiss 3T3 cells induced the formation of stress fibers and focal adhesions, whereas microinjection of the inactive catalytic domain, the Rho-binding domain, or the pleckstrin-homology domain inhibited the LPA-induced formation of stress fibers and focal adhesions. Thus, Rho-kinase appears to mediate signals from Rho and to induce the formation of stress fibers and focal adhesions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amano, M -- Chihara, K -- Kimura, K -- Fukata, Y -- Nakamura, N -- Matsuura, Y -- Kaibuchi, K -- New York, N.Y. -- Science. 1997 Feb 28;275(5304):1308-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Signal Transduction, Nara Institute of Science and Technology, Ikoma 630-01, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9036856" target="_blank"〉PubMed〈/a〉

    Epicardial FSTL1 reconstitution regenerates the adult mammalian heart (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-09-17
    Description: The elucidation of factors that activate the regeneration of the adult mammalian heart is of major scientific and therapeutic importance. Here we found that epicardial cells contain a potent cardiogenic activity identified as follistatin-like 1 (Fstl1). Epicardial Fstl1 declines following myocardial infarction and is replaced by myocardial expression. Myocardial Fstl1 does not promote regeneration, either basally or upon transgenic overexpression. Application of the human Fstl1 protein (FSTL1) via an epicardial patch stimulates cell cycle entry and division of pre-existing cardiomyocytes, improving cardiac function and survival in mouse and swine models of myocardial infarction. The data suggest that the loss of epicardial FSTL1 is a maladaptive response to injury, and that its restoration would be an effective way to reverse myocardial death and remodelling following myocardial infarction in humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4762253/" 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/PMC4762253/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, Ke -- Serpooshan, Vahid -- Hurtado, Cecilia -- Diez-Cunado, Marta -- Zhao, Mingming -- Maruyama, Sonomi -- Zhu, Wenhong -- Fajardo, Giovanni -- Noseda, Michela -- Nakamura, Kazuto -- Tian, Xueying -- Liu, Qiaozhen -- Wang, Andrew -- Matsuura, Yuka -- Bushway, Paul -- Cai, Wenqing -- Savchenko, Alex -- Mahmoudi, Morteza -- Schneider, Michael D -- van den Hoff, Maurice J B -- Butte, Manish J -- Yang, Phillip C -- Walsh, Kenneth -- Zhou, Bin -- Bernstein, Daniel -- Mercola, Mark -- Ruiz-Lozano, Pilar -- 5UM1 HL113456/HL/NHLBI NIH HHS/ -- HL065484/HL/NHLBI NIH HHS/ -- HL108176/HL/NHLBI NIH HHS/ -- HL113601/HL/NHLBI NIH HHS/ -- HL116591/HL/NHLBI NIH HHS/ -- K08 AI079268/AI/NIAID NIH HHS/ -- P01 HL098053/HL/NHLBI NIH HHS/ -- P30 AR061303/AR/NIAMS NIH HHS/ -- P30 CA030199/CA/NCI NIH HHS/ -- R01 HL086879/HL/NHLBI NIH HHS/ -- R01 HL113601/HL/NHLBI NIH HHS/ -- UM1 HL113456/HL/NHLBI NIH HHS/ -- England -- Nature. 2015 Sep 24;525(7570):479-85. doi: 10.1038/nature15372.

    Gas viscosity measurement with diamagnetic-levitation viscometer based on electromagnetically spinning system (2016)
    American Institute of Physics (AIP)
    Details
    Publication Date: 2016-12-09
    Description: Utilizing a graphite-disk probe attached with a thin aluminum disk, we have developed a friction-free viscosity measurement system. The probe is levitated above a NdFeB magnet because of diamagnetic effect and rotated by an electromagnetically induced torque. The probe is absolutely free form mechanical friction, and therefore, the accurate measurements of the viscosity of gases can be achieved. To demonstrate the accuracy and sensitivity of our method, we measured the viscosity of 8 kinds of gases and its temperature change from 278 K to 318 K, and we confirmed a good agreement between the obtained values and literature values. This paper demonstrates that our method has the ability to measure the fluid viscosity in the order of μ Pa ⋅ s.

    The ABCflux Database: Arctic-Boreal CO2 Flux and Site Environmental Data, 1989-2020 (2021)
    ORNL DAAC
    Details
    Publication Date: 2021-12-14
    Description: This Arctic-Boreal CO2 fluxes (ABCflux) dataset contains monthly aggregates of terrestrial net ecosystem CO2 exchange and its derived partitioned component fluxes: gross primary productivity (GPP) and ecosystem respiration. Over 70 supporting variables describe key site conditions (e.g., vegetation and disturbance type), micrometeorological and environmental measurements (e.g., air and soil temperatures), and flux measurement techniques. The data contained in this ABCflux dataset form a standardized monthly database of Arctic-Boreal CO2 fluxes (i.e., ABCflux Database) and include 244 sites and 6,309 monthly observations; 136 sites and 2,217 monthly observations represent tundra, and 108 sites and 4,092 observations represent the boreal biome. The data are for the period 1989 to 2020.

    The ABCflux database: Arctic–boreal CO〈sub>2〈/sub> flux observations and ancillary information aggregated to monthly time steps across terrestrial ecosystems (2022)
    In:  Earth System Science Data
    Details
    Publication Date: 2022-02-09
    Description: Past efforts to synthesize and quantify the magnitude and change in carbon dioxide (CO2) fluxes in terrestrial ecosystems across the rapidly warming Arctic–boreal zone (ABZ) have provided valuable information but were limited in their geographical and temporal coverage. Furthermore, these efforts have been based on data aggregated over varying time periods, often with only minimal site ancillary data, thus limiting their potential to be used in large-scale carbon budget assessments. To bridge these gaps, we developed a standardized monthly database of Arctic–boreal CO2 fluxes (ABCflux) that aggregates in situ measurements of terrestrial net ecosystem CO2 exchange and its derived partitioned component fluxes: gross primary productivity and ecosystem respiration. The data span from 1989 to 2020 with over 70 supporting variables that describe key site conditions (e.g., vegetation and disturbance type), micrometeorological and environmental measurements (e.g., air and soil temperatures), and flux measurement techniques. Here, we describe these variables, the spatial and temporal distribution of observations, the main strengths and limitations of the database, and the potential research opportunities it enables. In total, ABCflux includes 244 sites and 6309 monthly observations; 136 sites and 2217 monthly observations represent tundra, and 108 sites and 4092 observations represent the boreal biome. The database includes fluxes estimated with chamber (19 % of the monthly observations), snow diffusion (3 %) and eddy covariance (78 %) techniques. The largest number of observations were collected during the climatological summer (June–August; 32 %), and fewer observations were available for autumn (September–October; 25 %), winter (December–February; 18 %), and spring (March–May; 25 %). ABCflux can be used in a wide array of empirical, remote sensing and modeling studies to improve understanding of the regional and temporal variability in CO2 fluxes and to better estimate the terrestrial ABZ CO2 budget. ABCflux is openly and freely available online (Virkkala et al., 2021b, https://doi.org/10.3334/ORNLDAAC/1934).
