Purification And Functional Characterization Of The Iron-Responsive Transcription Factor Aft1 From C. Glabrata, Jade Ikahihifo-Bender

Senior Theses

Due to its unique ability to serve as both an electron donor and acceptor, iron is utilized as a co-factor for many biological processes, including electron transfer, oxygen binding, and vitamin synthesis. Iron is also a key factor during fungal infections as the human host and invading pathogens battle over limited iron pools. The primary iron-responsive transcription factor Aft1 in the opportunistic pathogenic yeast Candida glabrata responds to iron deficiency by activating expression of iron acquisition genes. However, the mechanisms for sensing intracellular iron levels and regulating Aft1 activity in response to iron are unknown. The C. glabrata iron regulation …

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 …

Cold-Induced Metabolic Changes In Lean, Nag-1 Transgenic Mice, Rachel J. Davey

All Master's Theses

Obesity is a multifaceted metabolic disorder with severe worldwide public health consequences. While obesity can often be treated using diet and exercise, there are complex genetic interactions driving obesity that don’t always respond to such changes. One important research focus for addressing genetic factors is activating brown adipose tissue which increases thermogenesis, the process of burning stored fats to generate heat. Cold exposure is a known way to activate brown adipose tissue through b3-adrenergic signaling. This signaling pathway causes an upregulation of thermogenesis in brown adipocytes and beige adipocytes, which is white adipose tissue that “browns” and becomes metabolically active. …

Regulation Of Mpcs And Kat8 During Adipogenesis And Nutritional Regulation, Jasmine Burrell

LSU Doctoral Dissertations

Obesity is a global epidemic characterized by an expansion of adipose tissue. Adipose tissue, composed of adipocytes and a stromal vascular fraction, is an endocrine organ that regulates whole body homeostasis. Obesity leads to the dysregulation of adipocytes and is often associated with increased susceptibility to metabolic diseases such as Type II diabetes mellitus (T2DM). Understanding the mechanisms by which adipocyte function and development are regulated is crucial. Mitochondrial pyruvate carriers (MPCs) are transmembrane proteins that transport pyruvate from the cytosol into the mitochondrial matrix to generate acetyl CoA. Although MPCs have been studied extensively, their roles in adipocytes are …

Determining The Link Between Advanced Glycation Endproducts (Ages), Feeding, And Metabolism, Lauren Wimer

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Reactive a-dicarbonyls (a-DC’s), such as methylglyoxal (MGO), are unavoidable metabolites generated during glycolysis that accumulate with age and have been linked with chronic age-related metabolic diseases such as Diabetes Mellitus. Diabetes Mellitus is generally characterized by peripheral neuropathy and sustained hyperglycemia. Chronic hyperglycemia leads to an increase in glycolysis and a downstream increase in reactive a-DC’s. The human body has a natural method of detoxifying these a-DC’s. Glycolytic cells have enzymes which can detoxify a-DC’s, but if overwhelmed, a-DC’s can accumulate and react non-enzymatically with proteins, lipids and DNA to yield a group of molecules called advanced glycation end-products (AGEs). …

Baseline Health Assessment Of A Rural Delta Community, Sydney Mitchell

Honors Theses

The Lower Mississippi Delta is characterized by poverty, chronic health issues, health disparities, and food insecurity. The rural Delta communities are primarily African American, experiencing disproportionately higher rates of poverty, job loss, and chronic health problems. Historically, chronic health issues have persisted in these areas over time, including obesity, hypertension, and diabetes, which have only seemed to increase in this region. The food environment in this rural region tends to assist in the creation of the largely obesogenic population which, in turn, contributes to the increased prevalence of diabetes and hypertension and a lower quality of life. Many residents in …

Serpinb1 Effects On Human Pancreatic Ductal Cells, Praneeth Goli

College of Arts & Sciences Senior Theses

Rebuilding or expanding the body’s ability to regulate blood glucose levels by restoring or increasing the body’s ability to produce insulin, long-term, would be a major advancement in diabetes (type-1 and type-2) treatment and could serve as a potential cure [1]. Therefore, the holy grail of diabetes treatment and cure research is to regenerate or increase the insulin producing cells in diabetic individuals (type-1 and type-2) [1, 2]. SerpinB1 has been implicated as a biomolecular signal that stimulates an increase in insulin cell mass in murine and zebrafish models that exhibit physiologically normal compensatory islet hyperplasia. In humans, SerpinB1 is …

Structural And Functional Characterization Of Mitochondria With Trna Mutations, Brooke Henry

Biological Sciences Undergraduate Honors Theses

Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is one of the most common disorders associated with mitochondrial tRNA mutations. One of the most common causes of MELAS is mutation in the MT-TL1 gene which codes for mitochondrial tRNA Leucine (UUR). Mutation in MT-TE gene, another mitochondrial gene which encodes for mitochondrial tRNA Glutamate (GAA/G), has been implicated in various mitochondrial related myopathies. It remains unclear how point mutations in these tRNA genes result in disease onset and progression. Here, we report an early comparative analysis of fibroblast cell lines derived from patients carrying two different tRNA mutations: m.3243A>G …

Genetic And Cellular Models For The Study Of Ptk2b And Adam10 In Adaptive Thermogenesis And Metabolism, Jared S. Farrar

Theses and Dissertations

In a cellular model, we demonstrate that the non-receptor protein tyrosine kinase 2 beta (PTK2B) plays a critical role in mouse cultured beige adipocyte differentiation. CRISPR/Cas9-mediated knock-out of Ptk2b results in non-differentiating white adipocytes and differentiated beige adipocytes with significantly reduced thermogenic gene and protein expression, enlarged lipid droplet size, and altered mitochondrial respiration. Together, these data in a cell culture system provide evidence for a role of PTK2B in the differentiation of mouse beige adipocytes.

In the process of developing a new mouse model utilizing the adipocyte selective Adipoq-Cre transgenic mouse, strong genetic linkage between a gene …

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3,4,5,6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to …

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue

Senior Theses

Phenylketonuria, now known as phenylalanine hydroxylase (PAH) deficiency, is a genetic disorder of metabolism affecting approximately one in every 15,000 infants born in the United States. Patients have nonfunctional PAH enzyme secondary to one or more genetic mutations. The enzyme deficit results in destructive supraphysiologic blood phenylalanine levels upon consumption of the essential dietary amino acid phenylalanine. Current standards of care mitigate signs and symptoms of the disorder, but do not approach a cure. The methods for creating a prototype pharmabiotic as an innovative treatment strategy for PAH deficiency are described herein.

Characterizing Aft1/2-Grx3/4 Interaction And The Role Of Bol2 During Iron Regulation In Saccharomyces Cerevisiae, William Rivers

Senior Theses

Iron dysregulation has been linked to a variety of human diseases, such as anemia, Friedreich’s ataxia, X-linked sideroblastic anemia, sideroblastic-like microcytic anemia, and myopathy. Thus, it is vitally important to understand the mechanisms for regulating intracellular iron. Here, we use fluorescence microscopy techniques in live cells to study interactions of the yeast proteins Grx3/4, Aft1/2, and Bol2, which have been shown to be involved in turning off iron import when the cell has adequate iron. Modified versions of genes encoding these proteins have been incorporated into several yeast backgrounds to use fluorescence to monitor interactions under varying iron levels.
