Prion Protein Glycosylation Is Not Required For Strain-Specific Neurotropism, Justin R. Piro, Brent T. Harris, Koren Nishina, Claudio Soto, Rodrigo Morales, Judy R. Rees, Surachai Supattapone

Dartmouth Scholarship

In this study, we tested the hypothesis that the glycosylation of the pathogenic isoform of the prion protein (PrP^Sc) might encode the selective neurotropism of prion strains. We prepared unglycosylated cellular prion protein (PrP^C) substrate molecules from normal mouse brain by treatment with PNGase F and used reconstituted serial protein cyclic misfolding amplification reactions to produce RML and 301C mouse prions containing unglycosylated PrP^Sc molecules. Both RML- and 301C-derived prions containing unglycosylated PrP^Sc molecules were infectious to wild-type mice, and neuropathological analysis showed that mice inoculated with these samples maintained strain-specific patterns of PrP …

Intravenous Inoculation Of A Bat-Associated Rabies Virus Causes Lethal Encephalopathy In Mice Through Invasion Of The Brain Via Neurosecretory Hypothalamic Fibers., Mirjam A R Preuss, Marie-Luise Faber, Gene S Tan, Michael Bette, Bernhard Dietzschold, Eberhard Weihe, Matthias J Schnell

Department of Microbiology and Immunology Faculty Papers

The majority of rabies virus (RV) infections are caused by bites or scratches from rabid carnivores or bats. Usually, RV utilizes the retrograde transport within the neuronal network to spread from the infection site to the central nervous system (CNS) where it replicates in neuronal somata and infects other neurons via trans-synaptic spread. We speculate that in addition to the neuronal transport of the virus, hematogenous spread from the site of infection directly to the brain after accidental spill over into the vascular system might represent an alternative way for RV to invade the CNS. So far, it is unknown …

Single-Amino-Acid Alterations In A Highly Conserved Central Region Of Vesicular Stomatitis Virus N Protein Differentially Affect The Viral Nucleocapsid Template Functions, Debasis Nayak, Debasis Panda, Subash C. Das, Ming Lou, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The nucleocapsid protein (N) of vesicular stomatitis virus and other rhabdoviruses plays a central role in the assembly and template functions of the viral N-RNA complex. The crystal structure of the viral N-RNA complex suggests that the central region of the N protein interacts with the viral RNA. Sequence alignment of rhabdovirus N proteins revealed several highly conserved regions, one of which spanned residues 282 to 291 (GLSSKSPYSS) in the central region of the molecule. Alanine-scanning mutagenesis of this region suggested that replacement of the tyrosine residue at position 289 (Y289) with alanine resulted in an N-RNA template that is …

Faculty Publications

Background - Comparisons of incidence and mortality rates are the metrics used most commonly to define cancer-related racial disparities. In the US, and particularly in South Carolina, these largely disfavor African Americans (AAs). Computed from readily available data sources, the mortality-to-incidence rate ratio (MIR) provides a population-based indicator of survival.

Methods - South Carolina Central Cancer Registry incidence data and Vital Registry death data were used to construct MIRs. ArcGIS 9.2 mapping software was used to map cancer MIRs by sex and race for 8 Health Regions within South Carolina for all cancers combined and for breast, cervical, colorectal, lung, …

Contributions Of Supportive Relationships To Heart Failure Self-Care, Margaret Sebern, Barbara Riegel

College of Nursing Faculty Research and Publications

Supportive relationships are known to improve outcomes for persons with heart failure (HF). Supporters may do so by improving self-care, but little is known about the influence of supportive relationships on HF self-care.

The purpose of this study was to explore background characteristics associated with supportive relationships, and the contribution of supportive relationships to HF self-care. The construct of shared care was used to operationalize supportive relationships. Shared care refers to a system of interpersonal processes (communication, decision making, and reciprocity) used in close relationships to exchange support. A cross sectional design was employed recruiting 75 HF dyads.

Interaction With Lc8 Is Required For Pak1 Nuclear Import And Is Indispensable For Zebrafish Development., Christine M Lightcap, Gabor Kari, Luis E Arias-Romero, Jonathan Chernoff, Ulrich Rodeck, John C Williams

Department of Biochemistry and Molecular Biology Faculty Papers

Pak1 (p21 activated kinase 1) is a serine/threonine kinase implicated in regulation of cell motility and survival and in malignant transformation of mammary epithelial cells. In addition, the dynein light chain, LC8, has been described to cooperate with Pak1 in malignant transformation of breast cancer cells. Pak1 itself may aid breast cancer development by phosphorylating nuclear proteins, including estrogen receptor alpha. Recently, we showed that the LC8 binding site on Pak1 is adjacent to the nuclear localization sequence (NLS) required for Pak1 nuclear import. Here, we demonstrate that the LC8-Pak1 interaction is necessary for epidermal growth factor (EGF)-induced nuclear import …
