A Periodicity-Sensitive Vector Index For Small Molecules, Ray Hefferlin, Ken Luk

Faculty Works

In the vastness of molecular space, there are many series X, XY, …, XYn…XYN, where N lies between 3 and say 10, whose data for a given property and phase are approximately linear with respect to n. A vectorial representation of the tabulated data in a series and a vector index to describe the series have been developed. The authors started with X as a metallic atom and with the property as heat of atomization, and showed that the vector index manifested periodicity. Then they moved to cases where X itself is a molecule and where the properties are enthalpies …

Protein Structure Similarity Clustering: Dynamic Treatment Of Pdb Structures Facilitates Clustering, Bradley D. Charette, Richard G. Macdonald, Stefan Wetzel, David B. Berkowitz, Herbert Waldmann

David Berkowitz Publications

Protein structure similarity clustering (PSSC) [1]– [3] is one of a number of potential guiding principles [4], [5] that have been introduced to focus combinatorial-library design/ protein targeting. PSSC clusters protein targets with similar ligand-binding cores in which little sequence or functional similarity is evident. Lead compounds for one member of the cluster then provide novel starting points in chemical space for ligand development for other members of the PSSC.

We describe herein a new clustering procedure that lends itself to ligand docking, molecular dynamics (MD), and the vector-alignment-search-tool (VAST) [6] algorithm. This MD-assisted approach offers an alternative to the …

Parental Death And Its Impact On The Marital Satisfaction Of The Surviving Adult Child, Ryan Glenn Henry

Theses and Dissertations

Previous literature has identified parental death as having a negative impact on the physical and mental health of the surviving adult child. In addition, research suggests that the marital satisfaction of a male or female adult child is negatively impacted after either a father or mother has died. The purpose of this research is to further study this topic by examining longitudinal dyadic data to determine how the death of a parent or death of an in-law impacts marital interaction when certain mediating variables are taken into account. Some of the mediating variables included quality of the parent-child relationship, caregiving, …

Translocation Of Molecules Into Cells By Ph-Dependent Insertion Of A Transmembrane Helix, Yana K. Reshetnyak, Oleg A. Andreev, Ursula Lehnert, Donald M. Engelman

Physics Faculty Publications

We have previously observed the spontaneous, pH-dependent insertion of a water-soluble peptide to form a helix across lipid bilayers [Hunt, J. F., Rath, P., Rothschild, K. J. & Engelman, D. M. (1997) Biochemistry 36, 15177–15192]. We now use a related peptide, pH (low) insertion peptide, to translocate cargo molecules attached to its C terminus across the plasma membranes of living cells. Translocation is selective for low pH, and various types of cargo molecules attached by disulfides can be released by reduction in the cytoplasm, including peptide nucleic acids, a cyclic peptide (phalloidin), and organic compounds. Because a high extracellular acidity …

A Survey Of Nuclear Ribosomal Internal Transcribed Spacer Substitution Rates Across Angiosperms: An Approximate Molecular Clock With Life History Effects, Kathleen M. Kay, Justen B. Whittall, Scott A. Hodges

Biology

Background: A full understanding of the patterns and processes of biological diversification requires the dating of evolutionary events, yet the fossil record is inadequate for most lineages under study. Alternatively, a molecular clock approach, in which DNA or amino acid substitution rates are calibrated with fossils or geological/climatic events, can provide indirect estimates of clade ages and diversification rates. The utility of this approach depends on the rate constancy of molecular evolution at a genetic locus across time and across lineages. Although the nuclear ribosomal internal transcribed spacer region ( nrITS) is increasingly being used to infer clade ages in …

Extensive Individual Variation In L1 Retrotransposition Capability Contributes To Human Genetic Diversity, Maria Del Carmen Seleme, Melissa R. Vetter, Richard Cordaux, Laurel Bastone, Mark A. Batzer, Haig H. Kazazian

Faculty Publications

Despite being scarce in the human genome, active L1 retrotrans-posons continue to play a significant role in its evolution. Because of their recent expansion, many L1s are not fixed in humans, and, when present, their mobilization potential can vary among individuals. Previously, we showed that the great majority of retrotransposition events in humans are caused by highly active, or hot. L1s. Here, in four populations of diverse geographic origins (160 haploid genomes), we investigated the degree of sequence poly-morphism of three hot L1s and the extent of individual variation in mobilization capability of their allelic variants. For each locus, we …

Lack Of Il-15 Results In The Suboptimal Priming Of Cd4+ T Cell Response Against An Intracellular Parasite, Crescent L. Combe, Magali M. Moretto, Joseph D. Schwartzman, Jason P. Gigley, David J. Bzik, Imtiaz A. Khan

Dartmouth Scholarship

IFN-gamma-producing CD4+ T cells, although important for protection against acute Toxoplasma gondii infection, can cause gut pathology, which may prove to be detrimental for host survival. Here we show that mice lacking IL-15 gene develop a down-regulated IFN-gamma-producing CD4+ T cell response against the parasite, which leads to a reduction in gut necrosis and increased level of survival against infection. Moreover, transfer of immune CD4+ T cells from WT to IL-15-/- mice reversed inhibition of gut pathology and caused mortality equivalent to levels of parental WT mice. Down-regulated CD4+ T cell response in the absence of IL-15, manifested as reduced …

Defocused Orientation And Position Imaging (Dopi) Of Myosin V, Rolfe G. Petschek

Faculty Scholarship

The centroid of a fluorophore can be determined within 1.5-nm accuracy from its focused image through fluorescence imaging with one-nanometer accuracy (FIONA). If, instead, the sample is moved away from the focus, the point-spread-function depends on both the position and 3D orientation of the fluorophore, which can be calculated by defocused orientation and position imaging (DOPI). DOPI does not always yield position accurately, but it is possible to switch back and forth between focused and defocused imaging, thereby getting the centroid and the orientation with precision. We have measured the 3D orientation and stepping behavior of single bifunctional rhodamine probes …

Invasive Plant Suppresses The Growth Of Native Tree Seedlings By Disrupting Belowground Mutualisms., Kristina A. Stinson, Stuart A. Campbell, Jeff R. Powell, Benjamin E. Wolfe, Ragan M. Callaway, Giles C. Thelen, Steven G. Hallett, Daniel Prati, John N. Klironomos

Department of Botany and Plant Pathology Faculty Publications

The impact of exotic species on native organisms is widely acknowledged, but poorly understood. Very few studies have empirically investigated how invading plants may alter delicate ecological interactions among resident species in the invaded range. We present novel evidence that antifungal phytochemistry of the invasive plant, Alliaria petiolata, a European invader of North American forests, suppresses native plant growth by disrupting mutualistic associations between native canopy tree seedlings and belowground arbuscular mycorrhizal fungi. Our results elucidate an indirect mechanism by which invasive plants can impact native flora, and may help explain how this plant successfully invades relatively undisturbed forest habitat.

Analysis Of Hiv-2 Vpx By Modeling And Insertional Mutagenesis, Lisa A. Mahnke, Michael Belshan, Lee Ratner

Nebraska Center for Virology: Faculty Publications

Vpx facilitates HIV-2 nuclear localization by a poorly understood mechanism. We have compared Vpx to an NMR structure HIV- 1 Vpr in a central helical domain and probed regions of Vpx by insertional mutagenesis. A predicted loop between helices two and three appears to be unique, overlapping with a known novel nuclear localization signal. Overall, Vpx was found to be surprisingly flexible, tolerating a series of large insertions. We found that insertion within the polyproline-containing C-terminus destabilizes nuclear localization, whereas mutating a second helix in the central domain disrupts viral packaging. Other insertional mutants in the predicted loop and in …

Lysine Residues In N-Terminal And C-Terminal Regions Of Human Histone H2a Are Targets For Biotinylation By Biotinidase, Yap Ching Chew, Gabriela Camporeale, Nagarama Kothapalli, Gautam Sarath, Janos Zempleni

Department of Nutrition and Health Sciences: Faculty Publications

In eukaryotic cell nuclei, DNA associates with the core histones H2A, H2B, H3 and H4 to form nucleosomal core particles. DNA binding to histones is regulated by posttranslational modifications of N-terminal tails (e.g., acetylation and methylation of histones). These modifications play important roles in the epigenetic control of chromatin structure. Recently, evidence that biotinidase and holocarboxylase synthetase (HCS) catalyze the covalent binding of biotin to histones has been provided. The primary aim of this study was to identify biotinylation sites in histone H2A and its variant H2AX. Secondary aims were to determine whether acetylation and methylation of histone H2A affect …
