Transcriptional Adaptations Following Exercise In Thoroughbred Horse Skeletal Muscle Highlights Molecular Mechanisms That Lead To Muscle Hypertrophy, Beatrice A. Mcgivney, Suzanne S. Eivers, David E. Machugh, James N. Macleod, Grace M. O'Gorman, Stephen D.E. Park, Lisa M. Katz, Emmeline W. Hill

Veterinary Science Faculty Publications

BACKGROUND: Selection for exercise-adapted phenotypes in the Thoroughbred racehorse has provided a valuable model system to understand molecular responses to exercise in skeletal muscle. Exercise stimulates immediate early molecular responses as well as delayed responses during recovery, resulting in a return to homeostasis and enabling long term adaptation. Global mRNA expression during the immediate-response period has not previously been reported in skeletal muscle following exercise in any species. Also, global gene expression changes in equine skeletal muscle following exercise have not been reported. Therefore, to identify novel genes and key regulatory pathways responsible for exercise adaptation we have used equine-specific …

Identifying Blood Biomarkers And Physiological Processes That Distinguish Humans With Superior Performance Under Psychological Stress., Amanda M. Cooksey, Nausheen Momen, Russell Stocker, Shane C. Burgess

CVM Publications

BACKGROUND: Attrition of students from aviation training is a serious financial and operational concern for the U.S. Navy. Each late stage navy aviator training failure costs the taxpayer over $1,000,000 and ultimately results in decreased operational readiness of the fleet. Currently, potential aviators are selected based on the Aviation Selection Test Battery (ASTB), which is a series of multiple-choice tests that evaluate basic and aviation-related knowledge and ability. However, the ASTB does not evaluate a person's response to stress. This is important because operating sophisticated aircraft demands exceptional performance and causes high psychological stress. Some people are more resistant to …

This invention provides for methods of obtaining improved immune responses in pigs to PRRSV, compositions useful for obtaining the improved immune responses as well as isolated polynucleotides that encode hypoglycosylated variants of PRRSV major surface protein GP5.

P03-01. The Relationship Of Envelope Evolution To Lentiviral Persistence And Vaccine Efficacy, J. K. Craigo, Charles J. Issel, R. C. Montelaro

Veterinary Science Presentations

We recently reported a direct, inverse, significant linear correlation of Env divergence from our live-attenuated vaccine strain (EIAVD9) and protection from disease. This marked effect of Env variation or viral evolution on vaccine efficacy begged the current questions: what is the relationship of Env variation and viral evolution to vaccine efficacy and does the evolution of virus in inapparent carriers differ from the evolution of attenuated vaccine viruses? Hence we further examined this relationship of Env divergence, evolution, and vaccine efficacy via investigations into Env evolution during inapparent infections, the elimination of ancestral viral species in infected ponies, and EIAVD9 …

An Eiav Field Isolate Reveals Much Higher Levels Of Subtype Variability Than Currently Reported For The Equine Lentivirus Family, Jodi K. Craigo, Shannon Barnes, Baoshan Zhang, Sheila J. Cook, Laryssa Howe, Charles J. Issel, Ronald C. Montelaro

Veterinary Science Faculty Publications

BACKGROUND: Equine infectious anemia virus (EIAV), a lentivirus that infects horses, has been utilized as an animal model for the study of HIV. Furthermore, the disease associated with the equine lentivirus poses a significant challenge to veterinary medicine around the world. As with all lentiviruses, EIAV has been shown to have a high propensity for genomic sequence and antigenic variation, especially in its envelope (Env) proteins. Recent studies have demonstrated Env variation to be a major determinant of vaccine efficacy, emphasizing the importance of defining natural variation among field isolates of EIAV. To date, however, published EIAV sequences have been …

The objective of this study was to evaluate transcriptional differences between chondrocytes of normal articular cartilage and repair tissue cells four months post-microfracture.

METHODS: Bilateral one-cm2 full-thickness defects were made in the articular surface of both distal femurs of four adult horses followed by subchondral microfracture. Four months postoperatively, repair tissue from the lesion site and grossly normal articular cartilage from within the same …

Proliferation And Apoptosis Of The Bitch Ovary During The Different Stages Of The Oestrous Cycle, Sayamon Srisuwatanasagul, Sukanya Manee-In, Promporn Raksaseri, Kongkiat Srisuwatanasagul

The Thai Journal of Veterinary Medicine

In order to maintain homeostasis of the ovary, proliferation and apoptosis occur simultaneously in different ovarian cell types. It was shown that steroid hormone which changed during the oestrous cycle, may regulate these mechanisms in normal mammal ovarian tissues. Therefore, the present study was aimed to study cell proliferation and apoptosis during different stages of the oestrous cycle in the bitch ovary by using immunohistochemistry and TUNEL assay. The bitch ovaries were collected at 4 different stages of the oestrous cycle, which were prooestrus, oestrus, dioestrus and anoestrus. Immunohistochemistry and TUNEL assay were applied to detect Ki-67 protein and apoptosis …

Atp Release By Infected Bovine Monocytes Increases The Intracellular Survival Of Mycobacterium Avium Subsp. Paratuberculosis, Seng-Ryong Woo, Raul G. Barletta, Charles Czuprynski

School of Veterinary and Biomedical Sciences: Faculty Publications

Mycobacterium avium subsp. paratuberculosis is the etiologic agent of Johne’s disease, a chronic intestinal infection in ruminants. Adenosine 5′-Triphosphate (ATP) has been reported to induce killing of several Mycobacterium species in human and murine macrophages. We investigated whether ATP secreted from M. avium subsp. paratuberculosis-infected bovine monocytes affects intracellular survival of the bacilli. Bovine monocytes constitutively secreted ATP during an 8-day incubation period in vitro; however, M. avium subsp. paratuberculosis infection did not enhance ATP release. Removal of extracellular ATP by the addition of apyrase increased the viability of infected monocytes, but surprisingly decreased the number of viable intracellular …

Penaeid Shrimp Immune System, Gabriel Aguirre-Guzman, Jesus Genaro Sanchez-Martinez, Angel Isidro Campa-Cordova, Antonio Luna-Gonzalez, Felipe Ascencio

The Thai Journal of Veterinary Medicine

Research on an innate immune system of penaeid shrimp is greatly motivated by economical requirements, because their culture is limited by the development of infectious diseases. As invertebrates, shrimp’s natural immunity acts as a fast and efficient defence mechanism against the pathogens. Their immune system involve hemocytes (for encapsulation, nodule formation and phagocytosis), several plasma components (antimicrobial peptides, histones, lysosomal enzymes, lipopolysaccharide, β-1,3-glucan binding proteins, and recognition molecules), and multimeric systems (clotting protein cascade, prophenoloxidase system). When these defense mechanisms fail to protect the shrimp against bacteria, viruses, fungi, protozoa and their products, disease develops and a negative impact takes …
