Co-Up-Regulation Of Three P450 Genes In Response To Permethrin Exposure In Permethrin Resistant House Flies, Musca Domestica, Fang Zhu, Ting Li, Lee Zhang, Nannan Liu

Entomology Faculty Publications

BACKGROUND: Insects may use various biochemical pathways to enable them to tolerate the lethal action of insecticides. For example, increased cytochrome P450 detoxification is known to play an important role in many insect species. Both constitutively increased expression (overexpression) and induction of P450s are thought to be responsible for increased levels of detoxification of insecticides. However, unlike constitutively overexpressed P450 genes, whose expression association with insecticide resistance has been extensively studied, the induction of P450s is less well characterized in insecticide resistance. The current study focuses on the characterization of individual P450 genes that are induced in response to permethrin …

Missense Mutation In Exon 2 Of Slc36a1 Responsible For Champagne Dilution In Horses, Deborah Cook, Samantha Brooks, Rebecca Bellone, Ernest Bailey

Veterinary Science Faculty Publications

Champagne coat color in horses is controlled by a single, autosomal-dominant gene (CH). The phenotype produced by this gene is valued by many horse breeders, but can be difficult to distinguish from the effect produced by the Cream coat color dilution gene (CR). Three sires and their families segregating for CH were tested by genome scanning with microsatellite markers. The CH gene was mapped within a 6 cM region on horse chromosome 14 (LOD = 11.74 for theta = 0.00). Four candidate genes were identified within the region, namely SPARC [Secreted protein, acidic, cysteine-rich (osteonectin)], SLC36A1 (Solute Carrier 36 family …

Tetrahymena Thermophila And Candida Albicans Group I Intron-Derived Ribozymes Can Catalyze The Trans-Excision-Splicing Reaction, P. Patrick Dotson Ii, Ashley K. Johnson, Stephen M. Testa

Chemistry Faculty Publications

Group I intron-derived ribozymes can catalyze a variety of non-native reactions. For the trans-excision-splicing (TES) reaction, an intron-derived ribozyme from the opportunistic pathogen Pneumocystis carinii catalyzes the excision of a predefined region from within an RNA substrate with subsequent ligation of the flanking regions. To establish TES as a general ribozyme-mediated reaction, intron-derived ribozymes from Tetrahymena thermophila and Candida albicans, which are similar to but not the same as that from Pneumocystis, were investigated for their propensity to catalyze the TES reaction. We now report that the Tetrahymena and Candida ribozymes can catalyze the excision of a …

Accelerated High Fidelity Prion Amplification Within And Across Prion Species Barriers, Kristi M. Green, Joaquín Castilla, Tanya S. Seward, Dana L. Napier, Jean E. Jewell, Claudio Soto, Glenn C. Telling

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Experimental obstacles have impeded our ability to study prion transmission within and, more particularly, between species. Here, we used cervid prion protein expressed in brain extracts of transgenic mice, referred to as Tg(CerPrP), as a substrate for in vitro generation of chronic wasting disease (CWD) prions by protein misfolding cyclic amplification (PMCA). Characterization of this infectivity in Tg(CerPrP) mice demonstrated that serial PMCA resulted in the high fidelity amplification of CWD prions with apparently unaltered properties. Using similar methods to amplify mouse RML prions and characterize the resulting novel cervid prions, we show that serial PMCA abrogated a transmission barrier …

Biology And Therapy Of Fibromyalgia. Evidence-Based Biomarkers For Fibromyalgia Syndrome, Dina Dadabhoy, Leslie J. Crofford, Michael Spaeth, I. Jon Russell, Daniel J. Clauw

Internal Medicine Faculty Publications

Researchers studying fibromyalgia strive to identify objective, measurable biomarkers that may identify susceptible individuals, may facilitate diagnosis, or that parallel activity of the disease. Candidate objective measures range from sophisticated functional neuroimaging to office-ready measures of the pressure pain threshold. A systematic literature review was completed to assess highly investigated, objective measures used in fibromyalgia studies. To date, only experimental pain testing has been shown to coincide with improvements in clinical status in a longitudinal study. Concerted efforts to systematically evaluate additional objective measures in research trials will be vital for ongoing progress in outcome research and translation into clinical …

Sumoylation Regulates Lamin A Function And Is Lost In Lamin A Mutants Associated With Familial Cardiomyopathies, Yu-Qian Zhang, Kevin D. Sarge

Molecular and Cellular Biochemistry Faculty Publications

Lamin A mutations cause many diseases, including cardiomyopathies and Progeria Syndrome. The covalent attachment of small ubiquitin-like modifier (SUMO) polypeptides regulates the function of many proteins. Until now, no examples of human disease-causing mutations that occur within a sumoylation consensus sequence and alter sumoylation were known. We show that lamin A is sumoylated at lysine 201 and that two lamin A mutants associated with familial dilated cardiomyopathy, E203G and E203K, exhibit decreased sumoylation. E203 occupies the conserved +2 position in the sumoylation consensus Psi KXE. Lamin A mutants E203G, E203K, and K201R all exhibit a similar aberrant subcellular localization and …

A Novel Application Of Quantile Regression For Identification Of Biomarkers Exemplified By Equine Cartilage Microarray Data, Liping Huang, Wenying Zhu, Christopher P. Saunders, James N. Macleod, Mai Zhou, Arnold J. Stromberg, Arne C. Bathke

Veterinary Science Faculty Publications

BACKGROUND: Identification of biomarkers among thousands of genes arrayed for disease classification has been the subject of considerable research in recent years. These studies have focused on disease classification, comparing experimental groups of effected to normal patients. Related experiments can be done to identify tissue-restricted biomarkers, genes with a high level of expression in one tissue compared to other tissue types in the body.

RESULTS: In this study, cartilage was compared with ten other body tissues using a two color array experimental design. Thirty-seven probe sets were identified as cartilage biomarkers. Of these, 13 (35%) have existing annotation associated with …

Nihilism With A Happy Ending? The Interstate Commerce Commission And The Emergence Of The Post-Enlightenment Paradigm, Mark F. Kightlinger

Law Faculty Scholarly Articles

This Article examines early Supreme Court opinions about the Interstate Commerce Commission (ICC)—the first federal administrative agency—in an effort to identify the intellectual roots of the modern administrative state. The Article argues that the Court's effort to explain and justify the function of the newborn ICC shows the traces of a post-Enlightenment crisis in the field of moral philosophy—i.e., the growing conviction that it is no longer possible for reasonable people to agree on what constitutes a true, objective, universally valid standard of reasonable or just conduct. From this essentially nihilistic starting point, the Court helped to fashion a new …

Aluminum Bioavailability From Basic Sodium Aluminum Phosphate, An Approved Food Additive Emulsifying Agent, Incorporated In Cheese, Robert A. Yokel, Clair L. Hicks, Rebecca L. Florence

Pharmaceutical Sciences Faculty Publications

Oral aluminum (Al) bioavailability from drinking water has been previously estimated, but there is little information on Al bioavailability from foods. It was suggested that oral Al bioavailability from drinking water is much greater than from foods. The objective was to further test this hypothesis. Oral Al bioavailability was determined in the rat from basic [26Al]-sodium aluminum phosphate (basic SALP) in a process cheese. Consumption of approximately 1g cheese containing 1.5% or 3% basic SALP resulted in oral Al bioavailability (F) of approximately 0.1% and 0.3%, respectively, and time to maximum serum 26Al concentration (Tmax) of 8-9h. These Al bioavailability …

Assessment Of A Non-Invasive High-Throughput Classifier For Behaviours Associated With Sleep And Wake In Mice, Kevin D. Donohue, Dharshan C. Medonza, Eli R. Crane, Bruce F. O'Hara

Biology Faculty Publications

This work presents a non-invasive high-throughput system for automatically detecting characteristic behaviours in mice over extended periods of time, useful for phenotyping experiments. The system classifies time intervals on the order of 2 to 4 seconds as corresponding to motions consistent with either active wake or inactivity associated with sleep. A single Polyvinylidine Difluoride (PVDF) sensor on the cage floor generates signals from motion resulting in pressure. This paper develops a linear classifier based on robust features extracted from normalized power spectra and autocorrelation functions, as well as novel features from the collapsed average (autocorrelation of complex spectrum), which characterize …

The Influence Of Citrate, Maltolate And Fluoride On The Gastrointestinal Absorption Of Aluminum At A Drinking Water-Relevant Concentration: A 26Al And 14C Study, Yuzhao Zhou, Wesley R. Harris, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

The objectives were to test the null hypotheses that (1) citrate, maltolate, and fluoride do not significantly influence oral Al bioavailability, C_max or T_max at an Al dose relevant to drinking water exposure; and (2) Al citrate and maltolate are absorbed intact from the gastrointestinal tract. Male Fisher rats were given 1 ml of solution intra-gastrically containing 1 nCi ²⁶Al (65 nmol total Al) as the Al³⁺ ion, or as complexes with ¹⁴C-citrate, ¹⁴C-maltolate or fluoride, during concurrent ²⁷Al iv infusion. Blood was repeatedly collected for serum ²⁶Al, total Al and ^{14 …}

Renin Inhibition Reduces Hypercholesterolemia-Induced Atherosclerosis In Mice, Hong Lu, Debra L. Rateri, David L. Feldman, Richard Charnigo, Akiyoshi Fukamizu, Junji Ishida, Elizabeth Grace Oesterling, Lisa A. Cassis, Alan Daugherty

Saha Cardiovascular Research Center Faculty Publications

The role of the renin angiotensin system (RAS) in atherosclerosis is complex because of the involvement of multiple peptides and receptors. Renin is the rate-limiting enzyme in the production of all angiotensin peptides. To determine the effects of renin inhibition on atherosclerosis, we administered the novel renin inhibitor aliskiren over a broad dose range to fat-fed LDL receptor-deficient (Ldlr^-/-) mice. Renin inhibition resulted in striking reductions of atherosclerotic lesion size in both the aortic arch and the root. Subsequent studies demonstrated that cultured macrophages expressed all components of the RAS. To determine the role of macrophage-derived angiotensin in …

Enkephalin-Encoding Herpes Simplex Virus-1 Decreases Inflammation And Hotplate Sensitivity In A Chronic Pancreatitis Model, Hong Yang, Terry A. Mcnearney, Rong Chu, Ying Lu, Yong Ren, David C. Yeomans, Steven P. Wilson, Karin N. Westlund

Physiology Faculty Publications

Background: A chronic pancreatitis model was developed in young male Lewis rats fed a high-fat and alcohol liquid diet beginning at three weeks. The model was used to assess time course and efficacy of a replication defective herpes simplex virus type 1 vector construct delivering human cDNA encoding preproenkephalin (HSV-ENK).

Results: Most surprising was the relative lack of inflammation and tissue disruption after HSV-ENK treatment compared to the histopathology consistent with pancreatitis (inflammatory cell infiltration, edema, acinar cell hypertrophy, fibrosis) present as a result of the high-fat and alcohol diet in controls. The HSV-ENK vector delivered to the pancreatic surface …

Application Of Prodrugs To Inflammatory Diseases Of The Gut, Helieh S. Oz, Jeffrey L. Ebersole

Center for Oral Health Research Faculty Publications

Oral delivery is the most common and preferred route of drug administration although the digestive tract exhibits several obstacles to drug delivery including motility and intraluminal pH profiles. The gut milieu represents the largest mucosal surface exposed to microorganisms with 10^10-12 colony forming bacteria/g of colonic content. Approximately, one third of fecal dry matter is made of bacteria/ bacterial components. Indeed, the normal gut microbiota is responsible for healthy digestion of dietary fibers (polysaccharides) and fermentation of short chain fatty acids such as acetate and butyrate that provide carbon sources (fuel) for these bacteria. Inflammatory bowel disease (IBD) results …

The Α1d-Adrenergic Receptor Is Expressed Intracellularly And Coupled To Increases In Intracellular Calcium And Reactive Oxygen Species In Human Aortic Smooth Muscle Cells, Mary L. García-Cazarín, Jennifer L. Smith, Kyle A. Olszewski, Dan F. Mccune, Linda A. Simmerman, Robert W. Hadley, Susan D. Kraner, Michael T. Piascik

Pharmacology and Nutritional Sciences Faculty Publications

Background: The cellular localization of the α_1D-adrenergic receptor (α_1D-AR) is controversial. Studies in heterologous cell systems have shown that this receptor is expressed in intracellular compartments. Other studies show that dimerization with other ARs promotes the cell surface expression of the α_1D-AR. To assess the cellular localization in vascular smooth muscle cells, we developed an adenoviral vector for the efficient expression of a GFP labeled α_1D-AR. We also measured cellular localization with immunocytochemistry. Intracellular calcium levels, measurement of reactive oxygen species and contraction of the rat aorta were used as measures of …
