School of Veterinary and Biomedical Sciences: Faculty Publications

Ovine progressive pneumonia virus (OPPV) is an important virus that causes serious diseases in sheep and goats with a prevalence of 36% in the USA. Although OPPV was discovered more than half of a century ago, little is known about the infection and pathogenesis of this virus. In this report, we used RNA-seq technology to conduct a genome-wide probe for cellular factors that are associated with OPPV infection. A total of approximately 22,000 goat host genes were detected of which 657 were found to have been significantly up-regulated and 889 down-regulated at 12 hours post-infection. In addition to previously known …

School of Veterinary and Biomedical Sciences: Faculty Publications

Acetylcholine binding proteins (AChBPs) are unique spatial homologs of the ligand-binding domains of nicotinic acetylcholine receptors (nAChRs), and they reproduce some pharmacological properties of nAChRs. X-ray crystal structures of AСhBP in complex with α-conotoxins provide important insights into the interactions of α-conotoxins with distinct nAChR subtypes. Although considerable efforts have been made to understand why α-conotoxin GIC is strongly selective for α3β2 nAChR, this question has not yet been solved. Here we present the structure of α-conotoxin GIC in complex with Aplysia californica AChBP (Ac-AChBP) at a resolution of 2.1 Å. Based on this co-crystal structure complemented with molecular docking …

Low Resting Metabolic Rate In Exercise-Associated Amenorrhea Is Not Due To A Reduced Proportion Of Highly Active Metabolic Tissue Compartments, Karsten Koehler, Nancy I. Williams, Rebecca J. Mallinson, Emily A. Southmayd, Heather C.M. Allaway, Mary Jane De Souza

Department of Nutrition and Health Sciences: Faculty Publications

Exercising women with menstrual disturbances frequently display a low resting metabolic rate (RMR) when RMR is expressed relative to body size or lean mass. However, normalizing RMR for body size or lean mass does not account for potential differences in the size of tissue compartments with varying metabolic activities. To explore whether the apparent RMR suppression in women with exercise-associated amenorrhea is a consequence of a lower proportion of highly active metabolic tissue compartments or the result of metabolic adaptations related to energy conservation at the tissue level, RMR and metabolic tissue compartments were compared among exercising women with amenorrhea …

Relationship Between Concentrations Of Lutein And Stard3 Among Pediatric And Geriatric Human Brain Tissue, Jirayu Tanprasertsuk, Binxing Li, Paul S. Bernstein, Rohini Vishwanathan, Mary Ann Johnson, Leonard Poon, Elizabeth J. Johnson

Department of Nutrition and Health Sciences: Faculty Publications

Lutein, a dietary carotenoid, selectively accumulates in human retina and brain. While many epidemiological studies show evidence of a relationship between lutein status and cognitive health, lutein’s selective uptake in human brain tissue and its potential function in early neural development and cognitive health have been poorly evaluated at a molecular level. The objective of this study was to evaluate the cross-sectional relationship between concentrations of brain lutein and StARD3 (identified as its binding protein in retinal tissue) among three age groups: infants (1–4 months, n = 10), older adults (55–86 years, n = 8), and centenarians (98–105 years, n …

Pharmacological And Genetic Modulation Of Rev-Erb Activity And Expression Affects Orexigenic Gene Expression, Ariadna Amador, Yongjun Wang, Subhashis Banerjee, Theodore M. Kameneka, Laura A. Solt, Thomas P. Burris

Department of Nutrition and Health Sciences: Faculty Publications

The nuclear receptors REV-ERBα and REV-ERBβ are transcription factors that play pivotal roles in the regulation of the circadian rhythm and various metabolic processes. The circadian rhythm is an endogenous mechanism, which generates entrainable biological changes that follow a 24-hour period. It regulates a number of physiological processes, including sleep/wakeful cycles and feeding behaviors. We recently demonstrated that REV-ERB-specific small molecules affect sleep and anxiety. The orexinergic system also plays a significant role in mammalian physiology and behavior, including the regulation of sleep and food intake. Importantly, orexin genes are expressed in a circadian manner. Given these overlaps in function …

Disparities In Access To Preventive Health Care Services Among Insured Children In A Cross Sectional Study, Christian King

Food Insecurity And Housing Instability In Vulnerable Families, Christian King

Department of Nutrition and Health Sciences: Faculty Publications

Reducing the prevalence of household food insecurity has been a long-standing objective of the federal government. Previous research has found many negative consequences of food insecurity for families and households but has not examined its relationship with housing instability. Using longitudinal data from the Fragile Families and Child Wellbeing Study, difference-in-difference models show that food insecurity is associated with housing instability. The association remains statistically significant after accounting for potential selection and unobserved heterogeneity using propensity score matching and excluding households that experienced prior housing instability from the sample. Examining potential mediating factors, I find that material hardship explains about …
