Long Acting Beta2-Adrenergic Receptor Agonists Reverse Diabetic Nephropathy And Liver Steatosis In Murine Models Of Diabetes And Are Associated With Protection In Retrospective Human Studies, Brennan Winkler

MUSC Theses and Dissertations

Diabetes Mellitus (DM) affects 13.9% of men and 14.3% of women worldwide, a total of approximately 828 million people. Patients with diabetes are at risk of several complications including diabetic nephropathy (DN) and metabolic-associated steatohepatitis (MASH). These diseases eventually lead to end stage kidney disease (ESKD) and liver failure requiring dialysis and organ transplantation. In addition, diabetes exacerbates disease severity of autosomal dominant polycystic kidney disease (ADPKD), the most common potentially lethal genetic disease to affect humans with a prevalence of 1 in 500-1000. Therefore, a therapeutic approach that can attenuate organ damage and restore function in patients with DM, …

Immunotherapies have greatly improved outcomes for patients with renal cell carcinoma (RCC), yet response rates remain suboptimal and the factors promoting therapy resistance versus sensitivity are incompletely understood. Currently, no preclinical model of orthotopic renal cancer exists that permits evaluation of tumor antigen–specific (TAS) CD8+ tumor-infiltrating lymphocytes (TILs). To address this deficiency, we developed a mouse renal cancer model that permits tracking of adoptively transferred TAS CD8+ T cells. Renca-LUC tumor cells were transduced to express tumor ERK (tERK), a model antigen expressing a one-amino-acid change from wild-type ERK, resulting in recognition by tERK/H-2Kd-specific DUC Thy1.1 …

Mansoura Journal of Dentistry

Objective: This study aimed to establish cephalometric norms for the Tanzanian population, assess sexual dimorphism in cephalometric measurements, and compare these findings with established Caucasian and West African norms to enhance orthodontic diagnosis and treatment planning. Materials and Methods: A crosssectional study was conducted on 309 subjects (142 males, 167 females) at Muhimbili University Dental Clinic. Cephalometric radiographs were digitally traced using Quick Ceph Studio. Reliability was assessed using the inter-class correlation coefficient. The Kolmogorov-Smirnov test checked normality, while one-sample t-tests and Student’s ttests (p < 0.05) were used for comparisons. Data were analyzed with RStudio. Results: Tanzanians showed significantly smaller craniofacial measurements than Caucasians. Males had larger skeletal dimensions than females. Compared to West Africans, Tanzanians had generally higher values, with a few exceptions. Conclusion: Tanzanians display distinct craniofacial characteristics, differing from both Caucasians and West Africans. These findings support the need for population-specific cephalometric norms to guide accurate orthodontic diagnosis and treatment.


Not Biological, But Built: Structural And Metabolic Pathways Driving Black Maternal Health Disparities In The United States, Alexandra I. Umegboh Jan 2026

Not Biological, But Built: Structural And Metabolic Pathways Driving Black Maternal Health Disparities In The United States, Alexandra I. Umegboh

CMC Senior Theses

Black infants in the United States are more than twice as likely to die before their first birthday than white infants, a disparity often attributed to genetics, behavior, or individual health choices. However, this idea is challenged by a key contradiction: African immigrant women consistently experience better birth outcomes than U.S.-born Black women despite being similarly racialized. This thesis investigates the origins of this reproductive advantage and the factors contributing to its decline over time. By drawing on epidemiological data, metabolic health research, and literature on African diasporic healing traditions, it argues that the “healthy immigrant effect” is not biological, …

Herbivore Identity And Species Richness Shape Fruit Chemical And Quality Responses To Foliar Herbivory, Xavier Ozowara, Taylor M. Sloey, Susan R. Whitehead

Biological Sciences Faculty Publications

The cascading consequences of foliar herbivory on fruit chemistry and quality remain relatively underexplored, with most existing studies focusing on the effects of only one or two attackers. In this study, we examine how increasing herbivore species richness during foliar herbivory alters strawberry (Fragaria × ananassa Duch) fruit quality and phenolic chemistry. We conducted a greenhouse experiment with single species feeding and different combinations of feeding by three generalist lepidopteran species: Spodoptera frugiperda, Heliothis virescens, Helicoverpa zea. Species fed on leaves for 72 h as fruits ripened, and fully ripe fruits were harvested 72 h after …

Organophosphate flame retardants (OPFRs) are used in many consumer products, and their presence in our environment raises concerns about potential health dangers. In humans, exposure to OPFRs, such as tris(1,3-dichloro-2-propyl) phosphate (TDCPP) is associated with metabolic disorders such as obesity, hyperglycemia, and insulin resistance. Our current study seeks to determine how TDCPP exposure affects body composition, glucose homeostasis, and energy balance in a rodent model. C57Bl/6 J mice were divided into two weight-matched groups and fed purified low phytoestrogen diets containing either 0.1 % DMSO (control) or TDCPP 415 mg/kg resulting in an approximate exposure of 50 mg/kg/day. Both male …


Contribution Of Metabolism-Independent Glucose Sensing To Metabolic Homeostasis, Nadia Rashid, Kavaljit H. Chhabra Jan 2026

Contribution Of Metabolism-Independent Glucose Sensing To Metabolic Homeostasis, Nadia Rashid, Kavaljit H. Chhabra

Pharmacology and Nutritional Sciences Faculty Publications

Glucose sensing and signaling are central to cellular metabolic machinery for the regulation of metabolic homeostasis. Glucose sensing has been almost always assumed to be coupled with glucose metabolism; however, recent findings have unraveled metabolism-independent sensing mechanisms. Here, we discuss whether glucose transporters (GLUTs) and sodium-glucose co-transporters (SGLTs) may also function as glucose sensors independent of their roles in transporting glucose. Moreover, we review the emerging roles of G protein-coupled receptors (GPCRs) in sensing glucose and, consequently, initiating its signaling pathways in a cell-specific manner. Altogether, this review offers insights into the newly identified glucose sensing mechanisms and highlights the …

Anatomical Atlas Of Kinase Responsiveness To Weight Gain: Adipose Depot Reprogramming In Diet-Induced Adiposity, Wang-Hsin Lee, Zachary A. Kipp, Sally N. Pauss, Genesee J. Martinez, Mei Xu, Terry D. Hinds, Jr.

Pharmacology and Nutritional Sciences Faculty Publications

Background/Objectives: Adipose tissue depots located at different anatomical sites exert differential functions in response to adiposity and glucose intolerance. These fat depots exhibit distinct metabolic signaling patterns that may influence pathological fat accumulation, thereby affecting the efficacy of anti-obesity interventions. Nonetheless, the mechanisms underpinning depot-specific signaling and pathway responsiveness remain insufficiently understood.

Methods: Kinase activity was characterized during the progression of adiposity across five adipose tissue depots in obese versus lean mice using the advanced PamGene kinome technology. Furthermore, kinase pathways in human preadipocytes and mouse 3T3-L1 preadipocytes were analyzed and compared with those in their differentiated, mature adipocytes. The …

Intermittent High-Fat, High-Sugar Access During Adolescence Drives Binge-Restriction Feeding And Reduced Weight Gain In A Food Unpredictability Model, Calvin G. Miller Jan 2026

Intermittent High-Fat, High-Sugar Access During Adolescence Drives Binge-Restriction Feeding And Reduced Weight Gain In A Food Unpredictability Model, Calvin G. Miller

CMC Senior Theses

Food insecurity affects nearly 48 million Americans and 318 million people worldwide, with very low food security disrupting normal eating habits through “feast-or-famine” episodes characterized by cycles of food overconsumption followed by restriction. This dietary pattern alters dopamine signaling within the mesocorticolimbic system — brain circuitry intimately linked to reward processing. This system includes the ventral tegmental area (VTA) and prefrontal cortex (PFC). Overstimulation can be promoted through sporadic high-fat, high-sugar diet (HFHSD) exposure, promoting dopamine neuron architecture alterations and binge-eating behavior. Adolescence represents a vulnerable window, as mesocorticolimbic dopamine projections undergo maturation during this period. Though evidence links food …


The Influence, Dependency, And Targeting Of Fatty Acid Uptake In Er+ Breast Cancer, Abigail E. Goen Jan 2026

The Influence, Dependency, And Targeting Of Fatty Acid Uptake In Er+ Breast Cancer, Abigail E. Goen

Dartmouth College Ph.D Dissertations

Estrogen Receptor-positive/ Human Epidermal Growth Factor 2-negative, breast cancer (ER+/HER2- BC) is the most prevalent subtype of BC, impacting millions of individuals. Although early screening and treatment with endocrine therapy has greatly enhanced survival, this subtype sustains a steady increase of risk for recurrent disease for decades after diagnosis, indicating the persistence of residual cancer cells that are capable of maintaining dormancy for >20 years prior to metastatic outgrowth. Dormant cells reprogram metabolic pathways which can be profoundly influenced by the tumor microenvironment in promoting quiescence or proliferation. Fatty acid oxidation dependency has been noted as a hallmark of drug …

The utilization of extensive datasets, such as those generated by DNA or RNA sequencing, has become a central focus in drug discovery and personalized medicine (PerMed). Nonetheless, these datasets are constrained by the absence of protein-functionality testing, which affects physiological responses. In this study, we employed PamGene PamStation technology to quantify protein function by kinase activity across more than 500 signaling pathways from patients with hepatocellular carcinoma (HCC). Using proteins derived from nine patients and five human HCC cell lines for drug discovery and the clinical trial-on-a-chip approach, we developed comprehensive PerMed scores from the PamStation data to differentiate individual …

Department of Otolaryngology (ENT) Faculty Publications

In recent years, several biologics targeting Type 2 inflammation have been developed for treating chronic rhinosinusitis with nasal polyps (CRSwNP). These have been studied in registrational randomized controlled trials (RCTs), which vary in their patient populations, trial design, endpoints, geography, timing, or data-handling processes. While (in)direct treatment comparisons and meta-analyses have been carried out to compare efficacy results from RCTs, often these fail to properly account for these between-study differences. Here, we summarize the key between-study differences that can influence trial outcomes and highlight the resulting challenges faced when comparing outcomes from different Phase III RCTs of biologics in CRSwNP.


Bariatric Surgery Impacts Immune Cell Metabolism And Function Dependent On Metabolic Status, Samantha N. Hart Jan 2026

Bariatric Surgery Impacts Immune Cell Metabolism And Function Dependent On Metabolic Status, Samantha N. Hart

University of Kentucky Doctoral Dissertations

Type 2 Diabetes (T2D), one of the top ten causes of death worldwide, is fueled by chronic inflammation. T2D is considered a metabolic disease, and there is a great push to target metabolic and associated inflammatory pathways to ameliorate the disease & its comorbidities i.e., obesity and cardiovascular disease. Thus far, clinical trials of anti-inflammatory drugs have had modest impacts on T2D and have not led to changes in clinical practice. This may in part be due to a gap in knowledge in the mechanism(s) driving obesity-associated chronic inflammation. I posit that metabolic abnormalities in immune cells in those with …
