Mechanism of ovarian-dependent enhancement of health and longevity in postreproductive female mice

Dynamic Fecal Microbiota Transfer From Mice With Western Diet-Induced Severe Colitis And Colon Tumorigenesis Did Not Exacerbate Colitis Symptoms Or Colon Tumorigenesis In Recipient Mice Fed Either The Ain93g Diet Or The Total Western Diet, Abby D. Benninghoff

Browse all Datasets

Consumption of the total Western diet (TWD) in mice has been shown to increase gut inflammation, promote colon tumorigenesis, and alter the fecal microbiome composition in mice as com-pared to mice fed a healthy diet, AIN93G (AIN). However, it is unclear whether the gut micro-biome contributes directly to colitis-associated CRC in this model. The objective of this study was to determine whether dynamic fecal microbiota transfer (FMT) from host mice fed either AIN or TWD basal diets would alter colitis symptoms or colitis-associated CRC in recipient mice, which were fed either AIN or TWD directly using a 2x2 factorial experiment …

Germ Cell-Depleted Ovaries Improve Metabolic Health In Post-Reproductive Mice, Kyleigh Tyler

Research on Capitol Hill

Reproductive senescence is correlated with many deleterious heath conditions. In human females, the decline of health associated with reproductive function is termed “menopause.“ One of the declining health factors is metabolism.

In order to understand how ovaries contribute to metabolic health, we further studied the structure of ovaries. Within ovaries, there are two main types of cells:

• Germ Cells (oocyte): Play a central role in reproduction (egg)
• Somatic Cells: Supporting cells for germ cells

This study aimed to understand the relationship between germ cells and somatic cells and how this relationship influenced metabolism.

Small-Animal Models Of Zika Virus, Justin G. Julander, Venkatraman Siddharthan

Animal, Dairy, and Veterinary Science Faculty Publications

Zika virus (ZIKV) infection can result in serious consequences, including severe congenital manifestations, persistent infection in the testes and neurologic sequelae. After a pandemic emergence, the virus has spread to much of the new world and has been introduced to many countries outside of endemic areas as infected travelers return to their home countries. Rodent models have been important in gaining a better understanding of the wide range of disease etiologies associated with ZIKV infection and for the initial phase of developing countermeasures to prevent or treat viral infections. We discuss herein the advantages and disadvantages of small animal models …

Development Of Murine Model For Enterovirus D68 In Ag-129 Mice, John Mcclatchy, Joseph Evans, Brett Hurst, Bart Tarbet

Biology Posters

Enterovirus D68 (EV-D68) is an emerging picornavirus virus which typically causes respiratory disease. In 2014, a nationwide outbreak of EV-D68 occurred, with a portion of these cases associated with neurological disease. At the time of this outbreak, no animal models existed for Enterovirus D68, making it difficult to characterize pathology and test potential therapeutics. To address this, we developed a mouse model of EVd68 infection in AG-129 mice (immuno-compromised mice).

Evaluation Of Immunomodulators, Interferons And Known In Vitro Sars-Cov Inhibitors For Inhibition Of Sars-Cov Replication In Balb/C Mice, Dale L. Barnard, C. W. Day, K. Bailey, M. Heiner, R. Montgomery, L. Lauridsen, P. K-S. Chan, R. W. Sidwell

Animal, Dairy, and Veterinary Science Faculty Publications

Compounds approved for therapeutic use and in vitro inhibitors of severe acute respiratory syndrome coronavirus (SARS-CoV) were evaluated for inhibition in the mouse SARS-CoV replication model. A hybrid interferon, interferon alpha (IFN-alpha) B/D, and a mismatched double-stranded (ds) RNA interferon (IFN) inducer, Ampligen® (poly I:poly C124), were the only compounds that potently inhibited virus titres in the lungs of infected mice as assessed by CPE titration assays. When mice were dosed intraperitoneally (i.p.) with IFN-alpha B/D once daily for 3 days beginning 4 h after virus exposure, SARS-CoV replication in the lungs of infected mice was reduced by 1 log10 …

Topical Cidofovir Is More Effective Than Is Parenteral Therapy For Treatment Of Progressive Vaccinia In Immunocompromised Mice, Donald F. Smee, K. W. Bailey, M-H. Wong, M. K. Wandersee, R. W. Sidwell

Animal, Dairy, and Veterinary Science Faculty Publications

Background.Severe complications may arise as a result of virus dissemination after smallpox (live vaccinia virus) vaccination, particularly in immunocompromised individuals. We developed a new mouse model for studying the effects of antiviral agents on progressive vaccinia virus infections.

Methods.Hairless mice were treated with cyclophosphamide (100 mg/kg/day) every 4 days starting 1 day before vaccinia virus exposure to wounded skin. Primary lesions progressed in severity, satellite lesions developed, and the infection eventually killed the mice.

Results.Topical treatment with 1%‐cidofovir cream (twice daily for 7 days) was much more effective in reducing the severity of primary lesions and the number of satellite …
