Faculty, Staff and Student Publications

Growing evidence supports a role for rest-activity rhythms (RARs) in metabolic health. Epidemiological studies in adolescents and young adults showed that RAR characteristics consistent with weakened rhythmicity were associated with obesity. However, studies in older adults are lacking. The objective of this study was to examine the cross-sectional and prospective associations between RAR and obesity in older men using the Harmonic Hidden Markov Model (HHMM), a novel analytical approach with several advantages over conventional methods for characterizing RAR. The analysis included nearly 3,000 participants in the Osteoporotic Fractures in Men study with 5-day 24-h actigraphy data. The strength of RAR …

Effects Of A 12-Week Plant-Based Diet Program On Obese And Overweight Adults In Rural Michigan, Nadine Larcher

Doctor of Nursing Practice Projects

Background

Overweight and obesity among adults are a rising epidemic in the U.S. Obesity is a risk factor for many chronic diseases and impacts morbidity and mortality. Despite our high-tech medical care system in the U.S., we are losing the war on obesity due to not addressing the underlying problems. These include unhealthy lifestyles and an unhealthy diet. A growing body of research studies has shown that adopting a low-fat whole food plant-based diet (WFPBD) regime consisting of whole grains, fruits, vegetables, legumes, and no animal-based products is an effective measure to counteract the rising pandemic of chronic diseases related …

Knockout Of Tsc2 In Nav1.8+ Neurons Predisposes To The Onset Of Normal Weight Obesity, Jennifer M Brazill, David Shin, Kristann Magee, Anurag Majumdar, Ivana R Shen, Valeria Cavalli, Erica L Scheller

2020-Current year OA Pubs

OBJECTIVE: Obesity and nutrient oversupply increase mammalian target of rapamycin (mTOR) signaling in multiple cell types and organs, contributing to the onset of insulin resistance and complications of metabolic disease. However, it remains unclear when and where mTOR activation mediates these effects, limiting options for therapeutic intervention. The objective of this study was to isolate the role of constitutive mTOR activation in Nav1.8-expressing peripheral neurons in the onset of diet-induced obesity, bone loss, and metabolic disease.

METHODS: In humans, loss of function mutations in tuberous sclerosis complex 2 (TSC2) lead to maximal constitutive activation of mTOR. To mirror this in …

Early Intervention And Intensive Management Of Patients With Diabetes, Cardiorenal, And Metabolic Diseases, Yehuda Handelsman, Samuel Klein, Et Al.

2020-Current year OA Pubs

Increasing rates of obesity and diabetes have driven corresponding increases in related cardiorenal and metabolic diseases. In many patients, these conditions occur together, further increasing morbidity and mortality risks to the individual. Yet all too often, the risk factors for these disorders are not addressed promptly in clinical practice, leading to irreversible pathologic progression. To address this gap, we convened a Task Force of experts in cardiology, nephrology, endocrinology, and primary care to develop recommendations for early identification and intervention in obesity, diabetes, and other cardiorenal and metabolic diseases. The recommendations include screening and diagnosis, early interventions with lifestyle, and …

The Tetraspanin Transmembrane Protein Cd53 Mediates Dyslipidemia And Integrates Inflammatory And Metabolic Signaling In Hepatocytes, Cassandra B Higgins, Joshua A Adams, Matthew H Ward, Zev J Greenberg, Małgorzata Milewska, Jiameng Sun, Yiming Zhang, Luana Chiquetto Paracatu, Qian Dong, Samuel Ballentine, Weikai Li, Ilona Wandzik, Laura G Schuettpelz, Brian J Debosch

2020-Current year OA Pubs

Tetraspanins are transmembrane signaling and proinflammatory proteins. Prior work demonstrates that the tetraspanin, CD53/TSPAN25/MOX44, mediates B-cell development and lymphocyte migration to lymph nodes and is implicated in various inflammatory diseases. However, CD53 is also expressed in highly metabolic tissues, including adipose and liver; yet its function outside the lymphoid compartment is not defined. Here, we show that CD53 demarcates the nutritional and inflammatory status of hepatocytes. High-fat exposure and inflammatory stimuli induced CD53 in vivo in liver and isolated primary hepatocytes. In contrast, restricting hepatocyte glucose flux through hepatocyte glucose transporter 8 deletion or through trehalose treatment blocked CD53 induction …

Methods: Using a quasi-experimental design, nine adults with …

Extracellular Matrix (Ecm) And Fibrosis In Adipose Tissue: Overview And Perspectives, Kai Sun, Xin Li, Philipp E Scherer

Faculty, Staff and Student Publications

Fibrosis in adipose tissue is a major driver of obesity-related metabolic dysregulation. It is characterized by an overaccumulation of extracellular matrix (ECM) during unhealthy expansion of adipose tissue in response to over nutrition. In obese adipose-depots, hypoxia stimulates multiple pro-fibrotic signaling pathways in different cell populations, thereby inducing the overproduction of the ECM components, including collagens, noncollagenous proteins, and additional enzymatic components of ECM synthesis. As a consequence, local fibrosis develops. The result of fibrosis-induced mechanical stress not only triggers cell necrosis and inflammation locally in adipose tissue but also leads to system-wide lipotoxicity and insulin resistance. A better understanding …

Over the last 2 decades, many African countries have undergone dietary and nutrition transitions fueled by globalization, rapid urbanization, and development. These changes have altered African food environments and, subsequently, dietary behaviors, including food acquisition and consumption. Dietary patterns associated with the nutrition transition have contributed to Africa's complex burden of malnutrition—obesity and other diet-related noncommunicable diseases (DR-NCDs)—along with persistent food insecurity and undernutrition. Available evidence links unhealthy or obesogenic food environments (including those that market and offer energy-dense, nutrient-poor foods and beverages) with suboptimal diets and associated adverse health outcomes. Elsewhere, governments have responded with policies to improve food …

PURPOSE: Overweight/obese (OW/OB) patients with metastatic melanoma unexpectedly have improved outcomes with immune checkpoint inhibitors (ICI) and BRAF-targeted therapies. The mechanism(s) underlying this association remain unclear, thus we assessed the integrated molecular, metabolic, and immune profile of tumors, as well as gut microbiome features, for associations with patient body mass index (BMI).

EXPERIMENTAL DESIGN: Associations between BMI [normal (NL < 25) or OW/OB (BMI ≥ 25)] and tumor or microbiome characteristics were examined in specimens from 782 patients with metastatic melanoma across 7 cohorts. DNA associations were evaluated in The Cancer Genome Atlas cohort. RNA sequencing from 4 cohorts (n = 357) was batch corrected and gene set enrichment analysis (GSEA) by BMI category was performed. Metabolic profiling was conducted in a subset of patients (x = 36) by LC/MS, and in flow-sorted melanoma tumor cells (x = 37) and patient-derived melanoma cell lines (x = 17) using the Seahorse XF assay. Gut microbiome features were examined in an independent cohort (n = 371).

RESULTS: DNA mutations and copy number variations were not associated with BMI. GSEA demonstrated that tumors from OW/OB patients were metabolically quiescent, with downregulation of oxidative phosphorylation and multiple other metabolic pathways. Direct metabolite analysis and functional metabolic profiling confirmed decreased …

A Low-Fat/Sucrose Diet Rich In Complex Carbohydrates Reverses High-Fat/Sucrose Diet-Induced Corneal Dysregulation, Prince K Akowuah, Carolina Lema, Rolando E Rumbaut, Alan R Burns

Faculty, Staff and Students Publications

High-fat/sucrose diet feeding in mice causes loss of corneal nerve function and impairs corneal wound healing. While changing to a diet with a low fat/sugar composition and enrichments in complex carbohydrates mitigates the reduction in nerve function, it remains to be determined if it has an effect on corneal wound healing. In this study, 6-week-old C57BL/6 male mice were fed either a normal diet or a high-fat/sucrose diet for 20 weeks. A third group (diet reversal) was placed on a high-fat/sucrose diet for 10 weeks followed by a normal diet for an additional 10 weeks. A central corneal epithelial abrasion …

High Body Mass Index Changes Peri-Tumor Adipose Tissue Which In Turn Promotes Triple Negative Breast Cancer, Cora Elizabeth Miracle

Theses, Dissertations and Capstones

Cancer is one of the leading causes of death worldwide, responsible for over half a million deaths each year. There are multiple risk factors associated with the development of cancer. Some of these risks include genetics, smoking, and most recently, obesity (Lewandowska et al., 2019) (De Pergola & Silvestris, 2013). Research has shown that obesity is linked to the promotion of fourteen different cancers, including aggressive triple negative breast cancer (TNBC). Patients that are obese are more likely to develop cancer (Park et al., 2014). In addition, if the patient is obese at the time of a cancer diagnosis, they …

Gut Microbial Metabolite Indole: A Stimulator Of Enteroendocrine Cell Differentiation Via Activation Of Aryl Hydrocarbon Receptor, James Hart

Theses, Dissertations and Capstones

Enteroendocrine cells (EECs) regulate energy balance and glucose homeostasis by releasing hormones in response to food intake. Dysregulated EEC differentiation is observed in obesity, while gut microbiota metabolites influence this process. Here, we investigated the role of indole, a biologically active gut microbial metabolite, in EEC differentiation through aryl hydrocarbon receptor (AhR) activation. Human intestinal organoids derived from jejunal mucosal biopsies were exposed to indole. Indole treatment significantly increased mRNA levels of chromogranin A, an EEC marker. The effect was reversed by an AhR antagonist, indicating AhR involvement. Indole also upregulated AhR target gene mRNA levels. These findings highlight the …
