Anthropometric measurements, body composition, and fasting measures of biochemical parameters were obtained at baseline and after six months of intervention. Results: 150 patients completed the …
Dietary Depletion Of Milk Exosomes And Their Microrna Cargos Elicits A Depletion Of Mir-200a-3p And Elevated Intestinal Inflammation And Chemokine (C-X-C Motif) Ligand 9 Expression In Mdr1a−/− Mice, Di Wu, Hatem Kittana, Jiang Shu, Stephen D. Kachman, Juan Cui, Amanda E. Ramer-Tait, Janos Zempleni
Dietary Depletion Of Milk Exosomes And Their Microrna Cargos Elicits A Depletion Of Mir-200a-3p And Elevated Intestinal Inflammation And Chemokine (C-X-C Motif) Ligand 9 Expression In Mdr1a−/− Mice, Di Wu, Hatem Kittana, Jiang Shu, Stephen D. Kachman, Juan Cui, Amanda E. Ramer-Tait, Janos Zempleni
Department of Nutrition and Health Sciences: Faculty Publications
Background: Exosomes transfer regulatory microRNAs (miRs) from donor cells to recipient cells. Exosomes and miRs originate from both endogenous synthesis and dietary sources such as milk. miR-200a-3p is a negative regulator of the proinflammatory chemokine (C-X-C motif) ligand 9 (CXCL9). Male Mdr1a−/− mice spontaneously develop clinical signs of inflammatory bowel disease (IBD).
Objectives: We assessed whether dietary depletion of exosomes and miRs alters the severity of IBD in Mdr1a−/− mice owing to aberrant regulation of proinflammatory cytokines.
Methods: Starting at 5 wk of age, 16 male Mdr1a−/− mice were fed either milk exosome– and RNA-sufficient (ERS) or milk exosome– and …

Omega-3 fatty acids are important to pregnancy and neonatal development and health. One mechanism by which omega-3 fatty acids exert their protective effects is through serving as substrates for the generation of specialized pro-resolving lipid mediators (SPM) that potently limit and resolve inflammatory processes. We recently identified that SPM levels are increased in maternal blood at delivery as compared to umbilical cord blood, suggesting the placenta as a potential site of action for maternal SPM. To explore this hypothesis, we obtained human placental samples and stained for the SPM resolvin D2 (RvD2) receptor GPR18 via immunohistochemistry. In so doing, we …

Department of Nutrition and Health Sciences: Faculty Publications
Previously we have shown in rats a new method of urine collection, hydrophobic sand, to be an acceptable alternate in place of the traditional method using metabolic cages. Hydrophobic sand is non-toxic, induces similar or lower levels of stress in the rat, and does not contaminate clinical urine markers nor metal concentrations in collected samples (Hoffman et al., 2017 and 2018). Urine is often used in humans and many animal models as a readily-attainable biosample which contains proteins and microRNAs (miRNAs) within extracellular vesicles (EVs) that can be isolated to indicate changes in health. In order to ensure hydrophobic sand …
Transport And Distribution Of Bovine Milk Exosomes And Mir-34a Cargo In Murine Cerebral Cortex Endothelial Bend.3 Cells And Bv2 Microglia, Pearl Ebea
Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research
The blood-brain barrier (BBB) poses an obstacle in the delivery of drugs to the brain. Bovine milk exosomes (BME) are explored for delivering antisense oligonucleotides to tumors, because BME are bioavailable and protect RNA cargos against degradation in the gastrointestinal tract. This study had the following objectives: 1) assess the transport kinetics of BME and their RNA cargos and secretion of RNA across the apical membrane in murine cerebral cortex endothelial bEnd.3 cells and 2) determine whether murine brain BV2 microglia have the potential to accumulate and, therefore, eliminate BME that crossed the BBB. The uptake of BME labeled with …
Inhibitory Effects Of Shiitake-Derived Exosome-Like Nanoparticles On Nlrp3 Inflammasome Activation, Yizhu Lu
Inhibitory Effects Of Shiitake-Derived Exosome-Like Nanoparticles On Nlrp3 Inflammasome Activation, Yizhu Lu
Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research
The NLRP3 inflammasome is a critical mediator of inflammation and consists of the sensor NOD-like receptor family, pyrin domain containing 3 (NLRP3), the adaptor apoptotic speck protein containing a caspase recruitment domain (ASC), and the effector caspase-1. Dysregulated or excessive activation of the NLRP3 inflammasome contributes to pathogenesis of diverse inflammatory diseases such as Type 2 diabetes and atherosclerosis. Therefore, the NLRP3 inflammasome is a promising therapeutic target for treating these diseases. Extracellular vesicles (EVs) are membrane-enclosed tiny particles released by almost any type of cells and they are involved in the intercellular communication by transferring their cargos including RNAs, …

Prioritization Of Variants For Investigation Of Genotype-Directed Nutrition In Human Superpopulations, Pascal D. Nilsson, Jacklyn M. Newsome, Henry M. Santos, Martin R. Schiller
Life Sciences Faculty Research
Dietary guidelines recommended by key health agencies are generally designed for a global population. However, ethnicity affects human disease and environment-gene interactions, including nutrient intake. Historically, isolated human populations with different genetic backgrounds have adapted to distinct environments with varying food sources. Ethnicity is relevant to the interaction of food intake with genes and disease susceptibility; yet major health agencies generally do not recommend food and nutrients codified by population genotypes and their frequencies. In this paper, we have consolidated published nutrigenetic variants and examine their frequencies in human superpopulations to prioritize these variants for future investigation of population-specific genotype-directed …

The objective was to determine if cooking skills and meal planning behaviors are associated with greater fruit and vegetable intake and lower body mass index (BMI) in first-year college students who are at risk for excessive weight gain. A cross-sectional analysis was conducted using baseline data from a multi-state research project aimed at preventing weight gain in first-year college students. Cooking type, frequency and confidence, self-instruction for healthful mealtime behavior intention, self-regulation of healthful mealtime behavior, and cup equivalents of fruits and vegetables (FV) were measured using validated surveys. BMI was calculated from measured height and weight. First-year students (n …
The Prevention Of Obesity-Associated Colorectal Cancer Via Dietary Suppression Of Inflammation-Driven Wnt-Signaling, Jinchao Li
Doctoral Dissertations
Colorectal cancer (CRC) is the third leading cause of cancer deaths in the United States. A number of population studies have established that modifiable lifestyle factors such as obesity plays an important role in colorectal carcinogenesis. In the United States, more than one-third of adults are obese and obesity prevalence rates have no sign of decrease. Therefore, the development of effective strategies to prevent obesity-induced CRC is a public health priority. This study aimed to investigate whether genetic or dietary strategies can prevent obesity-induced CRC and determine the potential molecular mechanisms underlying the prevention effects of these strategies. We used …

Potential Of Prebiotic Butyrogenic Fibers In Parkinson’S Disease, Thaisa M. Cantu-Jungles, Heather Rasmussen, Bruce R. Hamaker
Department of Nutrition and Health Sciences: Faculty Publications
Parkinson’s Disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons in the substantia nigra. Recent evidence supports the involvement of the gastrointestinal tract in PD pathogenesis, including alterations in microbiota and intestinal permeability. Apart from being the preferred energy source for colonic epithelial cells, butyrate is involved in anti-inflammatory, enteroendocrine and epigenetic mechanisms that influence colonic and systemic health, including brain function. A few studies using oral administration of sodium butyrate indicate beneficial effects in PD animal models; however, prebiotic fibers that generate butyrate locally in the gut may be more effective. The design and selection of …

Master's Theses
The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has increased over the past decades, creating a need for animal models that recapitulate the features of the pediatric disease. Iberian pigs have a leptin-resistant phenotype characterized by hyperleptinemia, hyperphagia, and extreme adipogenesis. We hypothesized that neonatal Iberian pigs fed a high fat high-fructose (HFF) diet will develop a pattern of liver injury resembling pediatric NAFLD. In addition, we sought to determine if a mixture of probiotics would prevent the disease. Animals were fed 1 of 4 diets containing (g/kg body weight × d) 0 g fructose, 11 g fat …

Platiscity Of C. Elegans Germline Stem Cells Under Nutritional And Metabolic Stress, Kenneth Trimmer
Platiscity Of C. Elegans Germline Stem Cells Under Nutritional And Metabolic Stress, Kenneth Trimmer
Dissertations & Theses (Open Access)
Stem cells are integral for tissue maintenance and fertility. Therefore, understanding how stem cells are regulated under stress is imperative. When confronted with acute starvation, stem cells must conserve energy and metabolites to cope with the lack of an external source. Caenorhabditis elegans germline stem cells (GSCs) are an excellent model for studying stem cell properties and regulation as they can divide throughout the life of the organism. While GSCs are an adult stem cell population, their cell cycle structure more closely mimics mouse and human embryonic stem cells with short G1 and long S phases. In this thesis, I …
Chemophobia And The Relation To Names, Justin Crow
Chemophobia And The Relation To Names, Justin Crow
Undergraduate Research Conference
Chemophobia is a recently identified cultural phenomena where people are afraid of chemicals in their lives, whether "chemicals" are in their food, their medicines, vaccinations, and other products. An increasing amount of people have a concern about the risk associated with chemicals in their everyday life. Chemistry professionals find this a bit strange as Chemistry states that all matter is made up of chemicals. Chemistry has many systems of naming and understanding chemicals which can exclude people from understanding the risk or lack thereof attributed to materials that are common in daily life. This effect could be accentuated by educational …

Micrornas In Bovine Milk Exosomes Are Bioavailable In Humans But Do Not Elicit A Robust Pro-Inflammatory Cytokine Response, Ezra Mutai, Amanda E. Ramer-Tait, Janos Zempleni
Department of Nutrition and Health Sciences: Faculty Publications
Background: Bovine milk exosomes are studied for their roles as bioactive food compounds and as vehicles for drug delivery. Both lines of investigation converge on immune function, e.g., immune regulation by absorption of microRNAs encapsulated in milk exosomes across species boundaries, and the possibility of exosomes and their cargos triggering an immune response if used in drug delivery. This study assessed the bioavailability of immune-related microRNAs from bovine milk and changes in plasma cytokine concentrations after milk consumption in humans, and the secretion of cytokines by human peripheral blood mononuclear cells (PBMCs) cultured with milk exosomes transfected with immune-relevant microRNAs. …

Background: Families who cook, eat, and play together have been found to have more positive health outcomes. Interventions are needed that effectively increase these health-related behaviors. Technology is often incorporated in health-related interventions but is not always independently assessed.
Objective: The objective of this study was to describe challenges and facilitators to incorporating technology into the iCook 4-H intervention program.
Methods: Dyads (n=228) composed of children (mean 9.4, SD 0.7 years old) and an adult primary meal preparer (mean 39.0, SD 8 years) were randomly assigned to a control (n=77) or treatment group (n=151). All treatment group dyads participated in …

Exosomes are natural nanoparticles that play an important role in cell-to-cell communication. Communication is achieved through the transfer of cargos, such as microRNAs, from donor to recipient cells and binding of exosomes to cell surface receptors. Exosomes and their cargos are also obtained from dietary sources, such as milk. Exosome and cell glycoproteins are crucial for intestinal uptake. A large fraction of milk exosomes accumulates in the brain, whereas the tissue distribution of microRNA cargos varies among distinct species of microRNA. The fraction of milk exosomes that escapes absorption elicits changes in microbial communities in the gut. Dietary depletion of …

This study compared athletic performance differences among high school American football combine participants originating from states of different population sizes. High school-aged American football players (n=7,214) who had participated in athletic performance combines between March 2015 and January 2016 were included in this analysis. Data included combine date and location, school state of origin, football position, class, height, weight, 10-, 20-, and 40-yd dash times, pro-agility, L-cone drill, vertical jump, broad jump, and power push-up. Participants were separated into high- (state population>10,000,000; HIGH; n=2,804), mid- (state population=5,000,000-9,999,999; MID; n=2,911), or low-population (state population<5,000,000; LOW; n=1,499) state of origin. Data were allometrically scaled to account for differences in body mass across high school grade levels and American football positions. All statistical analyses were performed on the allometrically scaled data. LOW athletes performed better than HIGH athletes in the 20-yd dash (p≤0.01). LOW athletes performed better than HIGH and MID in the 40-yd dash, proagility, broad jump, and power push-up (p<0.01). LOW and HIGH athletes performed better than MID in the Lcone and vertical jump (p<0.01). When considering population size, athletes originating from LOW states may demonstrate higher levels of athletic performance in football combine events hypothetically due to more opportunities for sports participation and playing time, leading to greater athletic development. Youth and high school coaches in MID and HIGH states might consider providing more opportunities for playing and individualized coaching to encourage long-term athletic development.
