Advanced Regenerative Manufacturing Institute (ARMI) The Department of Defense has announced an award of $80M to the non-profit Advanced Regenerative Manufacturing Institute (ARMI) located in Manchester, NH, led by Dean Kamen: www.armiusa.org. This award

Effects of Distal Residues Mutations on the Structure, Dynamics and Catalysis of Human Monoacylglycerol Lipase

January 29, 2018
Author(s)
Sergiy Tyukhtenko, Girija Rajarshi, Ioannis Karageorgos, Nikolai Zvonok, Elyssia S. Gallagher, Hongwei Huang, Kiran Vemuri, Jeffrey W. Hudgens, Alexandros Makriyannis
An understanding of how conformational dynamics modulates function and catalysis of human monoacylglycerol lipase (hMGL), an important pharmaceutical target, can facilitate the development of novel modulatory ligands. Here, we report the discovery and

Counting Caenorhabditis elegans: Protocol Optimization and Applications for Population Growth and Toxicity Studies in Liquid Medium

January 17, 2018
Author(s)
Steven Lund, Sanem Hosbas Coskun, Monique Johnson, Christopher Sims, Elijah Petersen, John T. Elliott, Bryant C. Nelson, Leona D. Scanlan, Shannon K. Hanna, Karina Brignoni, Patricia Lapasett
The nematode Caenorhabditis elegans is used extensively in molecular, toxicological and genetics research. However, standardized methods for counting nematodes in liquid culture do not exist despite the wide use of nematodes and need for accurate

Controlled Potential Electrooxidation of Genomic DNA

January 11, 2018
Author(s)
Vytautas Reipa, Donald H. Atha, Sanem Hosbas Coskun, Christopher M. Sims, Bryant C. Nelson
Exposure of mammalian cells to oxidative stress can result in DNA damage that adversely affects many cell processes. We used bulk electrolysis in an electrochemical system and gas chromatographic mass spectrometric analysis (GC/MS/MS) to control and

Quantitative analysis of the impact of a human pathogenic mutation on the CCT5 chaperonin subunit using a proxy archaeal ortholog

Darion Spigolon, David Travis Gallagher, Adrian Velazquez-Campoy, Donatella Bulone, Jatin Narang, Pier San Biagio, Francesco Cappello, Alberto J. Macario, Everly Conway de Macario, Frank Robb
The human chaperonin complex is a 1 MDa nanomachine composed of two octameric rings formed from eight similar but non-identical subunits called CCT. Here, we are elucidating the mechanism of a heritable CCT5 subunit mutation that causes profound neuropathy

Tissue Inhibitor of Metalloprotease-2: bioprocess development, physicochemical, biochemical and biological characterization of highly expressed recombinant protein

December 1, 2017
Author(s)
Ananda Chowdhury, Robert G. Brinson, Beiyang Wei, William G. Stetler-Stevenson
Tissue Inhibitor of Metalloprotease -2 (TIMP-2) is a secreted, 21 kDa, multifunctional protein. It was first described as an endogenous inhibitor of matrix metalloproteases (MMPs) that prevents protease-mediated breakdown of the extracellular matrix often

Quantitative Fluorescence Measurements with Multicolor Flow Cytometry

November 20, 2017
Author(s)
Lili Wang, Adolfas K. Gaigalas, James Wood
Multicolor flow cytometer assays are routinely used in clinical laboratories for immunophenotyping, monitoring disease and treatment, and determining prognostic factors. However, existing methods for quantitative measurements have not yet produced

The role of human monoacylglycerol lipase (hMAGL) binding pocket in breakup of unsaturated phospholipid membranes

November 1, 2017
Author(s)
Ioannis L. Karageorgos, Vitalii I. Silin, nikolai zvonok, John P. Marino, David Janero, Alexandros Makriyannis
Human monoacylglycerol lipase (hMAGL) plays a key role in homeostatic tuning of the endocannabinoid signaling system and supports aggressive tumorogenesis, making this enzyme a promising therapeutic target. hMAGL features a membrane-associated lid domain
