(Pro)Renin Receptor And Its Soluble Form In Metabolic Dysfunction: Friend Or Foe?, Gertrude Arthur
(Pro)Renin Receptor And Its Soluble Form In Metabolic Dysfunction: Friend Or Foe?, Gertrude Arthur
Journal of Pharmacology & Nutritional Sciences
(Pro)renin receptor is component of the renin angiotensin system which has been shown to be involved in several physiological and pathophysiological processes including blood pressure regulation and hypertension, water and electrolyte balance, kidney injury, obesity, and metabolic dysfunction. Enzymatic cleavage of prorenin receptor produces soluble prorenin receptor which can also activate the renin angiotensin system stimulate similar pathophysiological process like its full form receptor. This review explores findings on the role of prorenin receptor and soluble prorenin receptor in metabolic dysfunction and discusses the conflicting findings on soluble prorenin receptor in metabolic dysfunction.

Investigating The Relationship Between Metabolic Reprogramming And Peripheral Cd4+ T-Cell Inflammation In Human Type 2 Diabetes Pathogenesis, Gabriella Kalantar
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
Chronic, low-grade systemic inflammation rises in obesity and promotes type 2 diabetes (T2D). Circulating immune cells are key indicators of obesity and T2D pathogenesis. T cells outnumber monocytes, in blood, suggesting that T cells might fuel peripheral inflammation in obesity/T2D. Our lab’s work supports this idea by identification of a Th17 cytokine profile in T2D from T-cell stimulated peripheral blood mononuclear cells. Work described herein further supported this work by demonstrating that T cells dominate peripheral inflammation over monocytes across the spectrum of obesity and glycemic control. Our lab has also recently shown that inflammation changes during prediabetes (preT2D), identified …

Effects Of Constant Load Exercise On Oxygen Consumption And Knee Joint Mechanics In Young Adults, Mariana Victoria Jacobs
Theses and Dissertations--Kinesiology and Health Promotion
The rate of obesity and its adverse health consequences have continued to rise in the past several decades. Aerobic constant load exercise is recommended to reduce excess body mass, however the effects of constant load exercise on oxygen consumption (VO2) and knee joint mechanics are inconsistent when varying weight-status strategies are employed. The purpose of this study was to assess the influence of different weight classification strategies on VO2 and knee joint mechanics during constant load exercise. Participants walked on an instrumented treadmill at a self-selected speed for 30-minutes while gait mechanics and VO2 measures were determined. Between-group differences were …

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)
Obesity prevalence is at an alarmingly high rate within the United States, but especially in rural areas of Kentucky. Obesity can lead to a variety of negative physical health outcomes including heart disease, diabetes, stroke, and some cancers. There are also mental disorders associated with obesity through mechanisms such as weight stigma and self-perception. Similar to obesity rates, prevalence and mortality associated of these health outcomes are also seen at disproportionately higher rates in rural, Appalachian Kentucky. Causes for increased obesity and obesity related consequences include some genetic factors as well as behavioral factors like physical inactivity, poor diet, stress, …

INTRODUCTION: Behavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of individual and trial-level subgroups. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commencing antenatally or in the first year after birth, and …

We evaluated the relationship between glucose abnormalities and periodontitis in overweight/obese individuals. Eight hundred and seventy (870) diabetes-free participants aged 40–65 years completed the three-year follow-up in the San Juan Overweight Adults Longitudinal Study. The ADA thresholds for fasting and 2-h post-load glucose and HbA1c were used to define prediabetes. The NHANES methods were used to assess periodontitis. Multivariable linear regression was used to evaluate the relationship between baseline glucose metabolism measures and periodontitis at follow-up, adjusting for potential confounders. There was no association between impaired glucose measures and mean pocket depth (PD), mean clinical attachment loss (CAL), or mean …
Deletion Of Period Genes Exacerbates Diet-Induced Obesity In Female, But Not Male, Mice, Elizabeth Kantra
Deletion Of Period Genes Exacerbates Diet-Induced Obesity In Female, But Not Male, Mice, Elizabeth Kantra
Theses and Dissertations--Biology
Sex differences in obesity in mice are mediated by differential responses of circadian rhythms to high-fat feeding in males and females. Other studies also showed circadian Period genes regulate diet-induced obesity in mice. In this study, we investigated the role of the Period genes in regulating sex differences in obesity. Male and female C57BL/6J wild type, Per1/2 KO, and Per1/2/3 KO mice were housed in 12L:12D and fed high-fat diet for 12 weeks. We found a striking sex difference in obesity such that disabling the Period genes exacerbated adiposity in female, but not male, mice. Increased adiposity in female Period …

Modeling The Effects Of Adverse Childhood Experiences Using A Mouse Model Of Neglect: Mechanisms Of Adiposity Expansion In Females, Jacqueline Leachman
Theses and Dissertations--Pharmacology and Nutritional Sciences
Adverse childhood experiences (ACEs) are an independent risk factor for chronic disease, including obesity and metabolic syndrome. We have previously shown that a mouse model of early life stress, maternal separation and early weaning (MSEW), exacerbates high-fat diet (HF)-induced obesity only in adult female mice. In agreement, the analysis of several cohorts of participants exposed to ACEs have shown that women are more susceptible to develop obesity than men. Therefore, the aim of this study was to investigate the link between early life stress and obesity in pre-clinical and clinical settings. Male and female MSEW mice fed 1 week a …

The nuclear receptor PPARα is associated with reducing adiposity, especially in the liver, where it transactivates genes for β-oxidation. Contrarily, the function of PPARα in extrahepatic tissues is less known. Therefore, we established the first adipose-specific PPARα knockout (PparaFatKO) mice to determine the signaling position of PPARα in adipose tissue expansion that occurs during the development of obesity. To assess the function of PPARα in adiposity, female and male mice were placed on a high-fat diet (HFD) or normal chow for 30 weeks. Only the male PparaFatKO animals had significantly more adiposity in the inguinal white …

Why We Need A Ruminant Revolution: Combating Malnutrition And Metabolic Illnesses To Enable Sustainable Development, Peter J. Ballerstedt, David B. Hannaway, T. D. Noakes
IGC Proceedings (1997-2023)
Animal source foods (ASF) are essential for proper human development and function. Livestock in general, and ruminants in particular, are essential components of our sustainable global food systems. Of significant worldwide impact, diets with higher-than-recommended levels of ASF can correct the symptoms of metabolic illnesses, offering hope in arresting the current worldwide epidemic of diabetes and other metabolic diseases. Most dietary policy and recommendations are based on the ill-founded belief that plant-based, high-carbohydrate diets are “healthy.” High-quality scientific evidence does not support the belief that vegetarian diets are healthier than omnivorous or animal-based diets. A Therapeutic Carbohydrate Reduction (TCR) lifestyle …

BACKGROUND: Circulating levels of the endogenous inhibitor of nitric oxide synthase, asymmetric dimethylarginine (ADMA), are positively associated with the prevalence of metabolic syndrome (MetS) in cross-sectional investigations. It is unclear if circulating ADMA and other methylarginines are associated with incident MetS prospectively.
METHODS: We related circulating ADMA, symmetric dimethylarginine (SDMA), L-arginine (ARG) concentrations (measured with a validated tandem mass spectrometry assay) and the ARG/ADMA ratio to MetS and its components in 2914 (cross-sectional analysis, logistic regression; mean age 58 years, 55% women) and 1656 (prospective analysis, Cox regression; mean age 56 years, 59% women) individuals from the Framingham Offspring Study …

The purpose of this study was to examine associations between screen time (ST) parenting practices and 2–5-year-old children’s TV viewing and weight status. Data were collected from 252 parent–child dyads enrolled in a randomized parent-focused childhood obesity prevention trial from 2009–2012. ST parenting practices were assessed at baseline using a validated parent-reported survey. Parent-reported child TV viewing and objectively measured anthropometrics were assessed at baseline, post-intervention (35 weeks), and follow-up (59 weeks). Marginal effect models were developed to test the association between baseline ST parenting practices and children’s TV viewing, BMI z-score, and waist circumference across all time points. Limiting/monitoring …

Rural communities in Appalachia are displaying increased obesity prevalence, yet traditional interventions have not provided a broad enough impact to improve dietary consumption patterns. Therefore, expanding efforts that address the food environment and incorporate behavioral nudges through community-developed marketing strategies may be a viable mechanism to improve food and beverage choices within this unique population. This study installed shelf-wobblers across n = 5 gas stations in one rural Appalachian county in Kentucky. Smart Snacks were identified from store inventory lists utilizing the CDC Food Service Guideline for Federal Facilities calculator and were categorized into high-protein snacks, low-fat carbohydrate snacks, meal …

Background: The prevalence of hypertension is increasing particularly among obese children and adolescents. Obese children and adolescents with hypertension are likely to remain hypertensive as they reach adulthood and hypertension is linked to an increased risk for cardiovascular disease. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) has become one of the most important tools in diagnosing hypertension in children and adolescents and circadian patterns of blood pressure may be important disease-risk predictors.
Methods: A retrospective chart review was conducted in patients aged 6–21 years who underwent 24-h ABPM at Kentucky Children's Hospital (KCH) from August 2012 through June 2017. Exclusion criteria …

Grocery Food Taxes And U.S. County Obesity And Diabetes Rates, Lingxiao Wang, Yuqing Zheng, Steven Buck, Diansheng Dong, Harry M. Kaiser
Agricultural Economics Faculty Publications
BACKGROUND: Grocery food taxes represent a stable tax revenue stream for state and municipal government during times of adverse economic shocks such as that observed under the coronavirus disease 2019 (COVID-19) pandemic. Previous research, however, suggests a possible mechanism through which grocery taxes may adversely affect health. Our objectives are to document the spatial and temporal variation in grocery taxes and to empirically examine the statistical relationship between county-level grocery taxes and obesity and diabetes.
METHODS: We collect and assemble a novel national dataset of annual county and state-level grocery taxes from 2009 through 2016. We link this data to …

Pharmacology and Nutritional Sciences Faculty Publications
Background
Thrombospondin 1 (TSP1) is a multifunctional matricellular protein. We previously showed that TSP1 has an important role in obesity-associated metabolic complications, including inflammation, insulin resistance, cardiovascular, and renal disease. However, its contribution to obesity-associated non-alcoholic fatty liver disease/non-alcoholic steatohepatitis (NAFLD or NASH) remains largely unknown; thus, we aimed to determine its role.
Methods
High-fat diet or AMLN (amylin liver NASH) diet-induced obese and insulin-resistant NAFLD/NASH mouse models were utilised, in addition to tissue-specific Tsp1-knockout mice, to determine the contribution of different cellular sources of obesity-induced TSP1 to NAFLD/NASH development.
Results
Liver TSP1 levels were increased in experimental obese …

Knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Depression and obesity are highly comorbid among knee OA patients, and the combination of obesity and depression is associated with decreased physical activity, higher pain and disability, and more rapid cartilage degradation. Depression, obesity and OA exacerbate one another and share a common pathophysiology involving systemic inflammation and pro-inflammatory cytokines, reflecting a complex mind-body interaction. Current treatments for knee OA offer little to no benefit over placebo, and do not emphasize mind-body practices or physical activity to target the underlying pathophysiology. Mind-body …

In-Store Marketing Campaign To Promote The Purchase Of Healthy Foods And Beverages At Convenience Stores In Rural Kentucky, Brynnan Nicole Jacobs Dunaway
Theses and Dissertations--Nutrition and Food Systems
The prevalence of obesity is greater in rural communities, and current health promotion interventions have not shown broad positive impacts on dietary patterns in these areas. Focusing community-based efforts on unconventional food retailers is a unique avenue to encourage healthier food choices in rural populations. This study used shelf-wobblers to market healthier snack and beverage items at convenience stores (n=5) in a rural Kentucky county. Selection of healthy snacks and beverages from the store inventory was conducted using the CDC Food Service Guidelines for Federal Facilities calculator. Items were sorted into four categories: meal replacement snacks, high-protein snacks, low-fat carbohydrate …

Three Essays On Grocery Sales Taxes, Lingxiao Wang
Theses and Dissertations--Agricultural Economics
Grocery sales taxes represent a stable tax revenue stream for state and municipal government, but there is rare empirical evidence suggesting grocery taxes may adversely affect health. In addition, the how governments set grocery sales taxes is still unclear. Therefore, based on a novel national dataset of annual county and state-level grocery taxes from 2009 through 2016, the following three essays in the dissertation investigate the health impacts of grocery sales taxes and the causes of grocery sales taxes in a framework of tax competition.
In the first essay, we document the spatial and temporal variation in grocery taxes and …
Human Regulatory T Cells Control Inflammation From Effector T Cells In Prediabetes, Rui Liu
Human Regulatory T Cells Control Inflammation From Effector T Cells In Prediabetes, Rui Liu
Theses and Dissertations--Pharmacy
Type 2 diabetes (T2D) is a chronic low-grade inflammatory disease. A T cell cytokine profile (Th17) from PBMCs can distinguish obese T2D from obese non-diabetes subjects. Individual T cell subsets interact with each other and the diverse subsets jointly determine overall inflammation. Cellular metabolism drives cytokine production of CD4+ T cells, and therefore contributes to inflammation in T2D. However, specific changes in metabolism and function of CD4+ T cells during the progression from lean healthy to obese and diabetic stages in people have not been clarified.
We hypothesize that human regulatory T cells (Treg) impact metabolism of effector …

Introduction
Obesity disproportionately affects rural communities, and Appalachia has some of the highest obesity rates in the nation. Successful policy, systems, and environmental (PSE) interventions to reduce obesity must reflect the circumstances of the population. We used a health equity lens to identify barriers and facilitators for healthy food access in Martin County, Kentucky, to design interventions responsive to social, cultural, and historical contexts.
Methods
We conducted 5 focus groups in Martin County, Kentucky, in fall 2019 to obtain perspectives on the local food system and gauge acceptability of PSE interventions. We used grounded theory to identify perceived barriers and …

The inverse relationship of plasma bilirubin levels with liver fat accumulation has prompted the possibility of bilirubin as a therapeutic for non-alcoholic fatty liver disease. Here, we used diet-induced obese mice with non-alcoholic fatty liver disease treated with pegylated bilirubin (bilirubin nanoparticles) or vehicle control to determine the impact on hepatic lipid accumulation. The bilirubin nanoparticles significantly reduced hepatic fat, triglyceride accumulation, de novo lipogenesis, and serum levels of liver dysfunction marker aspartate transaminase and ApoB100 containing very-low-density lipoprotein. The bilirubin nanoparticles improved liver function and activated the hepatic β-oxidation pathway by increasing PPARα and acyl-coenzyme A oxidase 1. …

Mechanisms that enhance energy expenditure are attractive therapeutic targets for obesity. Previously we have demonstrated that mice lacking cd47 are leaner, exhibit increased energy expenditure, and are protected against diet-induced obesity. In this study, we further defined the physiological role of cd47 deficiency in regulating mitochondrial function and energy expenditure in both white and brown adipose tissue. We observed that cd47 deficient mice (under normal chow diet) had comparable amount of white fat mass but reduced white adipocyte size as compared to wild-type mice. Subsequent ex vivo and in vitro studies suggest enhanced lipolysis, and not impaired lipogenesis or energy …

Exercise in humans and animals increases plasma bilirubin levels, but the mechanism by which this occurs is unknown. In the present study, we utilized rats genetically selected for high capacity running (HCR) and low capacity running (LCR) to determine pathways in the liver that aerobic exercise modifies to control plasma bilirubin. The HCR rats, compared to the LCR, exhibited significantly higher levels of plasma bilirubin and the hepatic enzyme that produces it, biliverdin reductase-A (BVRA). The HCR also had reduced expression of the glucuronyl hepatic enzyme UGT1A1, which lowers plasma bilirubin. Recently, bilirubin has been shown to activate the peroxisome …
