BACKGROUND: Regulation of the thermogenic response by brown adipose tissue (BAT) is an important component of energy homeostasis with implications for the treatment of obesity and diabetes. Our preliminary analyses of RNA-Seq data uncovered many nodes representing epigenetic modifiers that are altered in BAT in response to chronic thermogenic activation. Thus, we hypothesized that chronic thermogenic activation broadly alters epigenetic modifications of DNA and histones in BAT.

RESULTS: Motivated to understand how BAT function is regulated epigenetically, we developed a novel method for the first-ever unbiased top-down proteomic quantitation of histone modifications in BAT and validated our results with a …

Type VI CRISPR-Cas systems are among the few CRISPR varieties that target exclusively RNA. The CRISPR RNA–guided, sequence-specific binding of target RNAs, such as phage transcripts, activates the type VI effector, Cas13. Once activated, Cas13 causes collateral RNA cleavage, which induces bacterial cell dormancy, thus protecting the host population from the phage spread. We show here that the principal form of collateral RNA degradation elicited by Leptotrichia shahii Cas13a expressed in Escherichia coli cells is the cleavage of anticodons in a subset of transfer RNAs (tRNAs) with uridine-rich anticodons. This tRNA cleavage is accompanied by inhibition of protein synthesis, thus …

Research Proposal: The Effects Of Creatine Supplementation On High School Athletes, Rebecca Kerr, Lacaya Evans

Department of Nutrition Student Projects

Creatine is commonly used among the adolescent athletic population. The prevalence rates are higher for anaerobic sports, for example, wrestling, football, and hockey. While creatine is a supplement of choice for many young athletes, its effects on performance are not well researched. Though studies point toward it being effective and safe, with few negative side effects documented, further analysis is needed to ensure it will not affect teens’ development. Therefore, this study aims to examine how creatine supplementation by high school athletes affects muscle development and its safety. Distributing creatine supplements to youth raises ethical concerns. Therefore, this study will …

Female Athlete Triad And Bone Stress Injuries, Amanda Nguyen

Honors College Theses

The Female Athlete Triad is still an ongoing and developing diagnosis that analyzes low energy availability, and its impact on menstrual dysfunction and bone mineral density in women. Through researching I analyzed what the Female Athlete Triad was, how it impacts our body and performance, and specifically how it relates to bone stress injuries. It was found that athletes with low energy availability are more likely to develop menstrual dysfunction, leading to low bone mineral density due to the negative impacts that both low energy availability and menstrual dysfunction have on important hormones. With low bone mineral density and compensations …

Vegetation Dieback In The Mississippi River Delta Triggered By Acute Drought And Chronic Relative Sea-Level Rise, Tracy Elsey-Quirk, Austin Lynn, Michael Derek Jacobs, Rodrigo Diaz, James T Cronin, Lixia Wang, Haosheng Huang, Dubravko Justic

Faculty, Staff and Student Publications

Vegetation dieback and recovery may be dependent on the interplay between infrequent acute disturbances and underlying chronic stresses. Coastal wetlands are vulnerable to the chronic stress of sea-level rise, which may affect their susceptibility to acute disturbance events. Here, we show that a large-scale vegetation dieback in the Mississippi River Delta was precipitated by salt-water incursion during an extreme drought in the summer of 2012 and was most severe in areas exposed to greater flooding. Using 16 years of data (2007-2022) from a coastwide network of monitoring stations, we show that the impacts of the dieback lasted five years and …

Effects Of The Sudden Reduction Of Social Enrichment On A Novel Rat Model Of Approach Orientation, Emily Feldman

Undergraduate Honors Theses

The goal of the present study was to evaluate the effects of a reduction in social enrichment by measuring behavioral changes in the Elevated Plus Maze (EPM) in male and female rats of High Approach (HAO) and Low Approach Orientation (LAO). The results indicated that at baseline, both total arm entries and open arm entries were affected by Approach Orientation and Sex. The percent change in closed arm entries in female LAO was sensitive to a sudden transition from high to standard social enrichment, whereas those in the female HAO and both male groups were behaviorally unaffected. The female LAO …

Chromosomal 3q Amplicon Encodes Essential Regulators Of Secretory Vesicles That Drive Secretory Addiction In Cancer, Xiaochao Tan, Shike Wang, Guan-Yu Xiao, Chao Wu, Xin Liu, Biyao Zhou, Jiang Yu, Dzifa Yawa Duose, Yuanxin Xi, Jing Wang, Kunika Gupta, Apar Pataer, Jack A Roth, Michael P Kim, Fengju Chen, Chad J Creighton, William K Russell, Jonathan M Kurie

Faculty, Staff and Student Publications

Cancer cells exhibit heightened secretory states that drive tumor progression. Here, we identify a chromosome 3q amplicon that serves as a platform for secretory regulation in cancer. The 3q amplicon encodes multiple Golgi-resident proteins, including the scaffold Golgi integral membrane protein 4 (GOLIM4) and the ion channel ATPase Secretory Pathway Ca2+ Transporting 1 (ATP2C1). We show that GOLIM4 recruits ATP2C1 and Golgi phosphoprotein 3 (GOLPH3) to coordinate calcium-dependent cargo loading and Golgi membrane bending and vesicle scission. GOLIM4 depletion disrupts the protein complex, resulting in a secretory blockade that inhibits the progression of 3q-amplified malignancies. In addition to its role …

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig

Thinking Matters Symposium

Neutrophils, also called polymorphonuclear leukocytes (PMNs), constitute the majority of innate immune cells. These cells possess a complex arsenal of functions that allow them to detect and eliminate a broad spectrum of pathogens. Neutropenia is characterized by decreased levels of neutrophils in the bloodstream, typically falling below the normal range. Moderate to severe neutropenia can increase the risk of pathogenic infections and without treatment can be life-threatening. Although the concentration of neutrophils in neutropenic individuals is decreased, upon activation, neutrophils still release neutrophil extracellular traps (NETs). NETs are pivotal in combating a spectrum of pathogens through their non-selective nature. Overreactive …

The Swi/Snf Atp-Dependent Chromatin Remodeling Complex In Cell Lineage Priming And Early Development, Dhurjhoti Saha, Srinivas Animireddy, Blaine Bartholomew

Faculty, Staff and Student Publications

ATP dependent chromatin remodelers have pivotal roles in transcription, DNA replication and repair, and maintaining genome integrity. SWI/SNF remodelers were first discovered in yeast genetic screens for factors involved in mating type switching or for using alternative energy sources therefore termed SWI/SNF complex (short for SWItch/Sucrose NonFermentable). The SWI/SNF complexes utilize energy from ATP hydrolysis to disrupt histone-DNA interactions and shift, eject, or reposition nucleosomes making the underlying DNA more accessible to specific transcription factors and other regulatory proteins. In development, SWI/SNF orchestrates the precise activation and repression of genes at different stages, safe guards the formation of specific cell …

The basal breast cancer subtype is enriched for triple-negative breast cancer (TNBC) and displays consistent large chromosomal deletions. Here, we characterize evolution and maintenance of chromosome 4p (chr4p) loss in basal breast cancer. Analysis of The Cancer Genome Atlas data shows recurrent deletion of chr4p in basal breast cancer. Phylogenetic analysis of a panel of 23 primary tumor/patient-derived xenograft basal breast cancers reveals early evolution of chr4p deletion. Mechanistically we show that chr4p loss is associated with enhanced proliferation. Gene function studies identify an unknown gene, C4orf19, within chr4p, which suppresses proliferation when overexpressed-a member of the PDCD10-GCKIII kinase module …

Faculty, Staff and Student Publications

BACKGROUND: Cancer is a life-threatening, stressful event, particularly for young adults due to delays and disruptions in their developmental transitions. Cancer treatment can also cause adverse long-term effects, chronic conditions, psychological issues, and decreased quality of life (QoL) among young adults. Despite numerous health benefits of health behaviors (eg, physical activity, healthy eating, no smoking, no alcohol use, and quality sleep), young adult cancer survivors report poor health behavior profiles. Determining the associations of stress (either cancer-specific or day-to-day stress), health behaviors, and QoL as young adult survivors transition to survivorship is key to understanding and enhancing these survivors' health. …

Department of Medical Oncology Faculty Papers

Urothelial carcinoma (UC) is the fourth most prevalent cancer amongst males worldwide. While patients with non-muscle-invasive disease have a favorable prognosis, 25% of UC patients present with locally advanced disease which is associated with a 10-15% 5-year survival rate and poor overall prognosis. Muscle-invasive bladder cancer (MIBC) is associated with about 50% 5 year survival when treated by radical cystectomy or trimodality therapy; stage IV disease is associated with 10-15% 5 year survival. Current therapeutic modalities for MIBC include neoadjuvant chemotherapy, surgery and/or chemoradiation, although patients with relapsed or refractory disease have a poor prognosis. However, the rapid success of …

Exploration Of Enterococcus Faecalis Bacteriophages Diversity: Comprehensive Phylogenetic Analysis And Discovery Isolation Of Enterococcus Faecalis Phage From A Soil Sample In South Florida, Hailey N. Jauernick

All HCAS Student Capstones, Theses, and Dissertations

Enterococcus faecalis is a commensal bacterium found in the gastrointestinal tract, oral cavity, and vagina of humans, which can transition to pathogenic states, leading to diverse infections. Many E. faecalis infections are becoming progressively challenging to treat, stemming from the lack of effective antibiotic therapies against its virulence factors, including biofilm formation and antibiotic resistance. Phage therapy emerges as a promising alternative, targeting bacteria with minimal impact on host flora. However, despite phages' ubiquitous presence and potential applications in medicine and biotechnology, their diversity and ecological niches are vastly understudied. Here, we investigated the diversity of sequenced E. faecalis phages …

An Estrogen Receptor Α-Derived Peptide Improves Glucose Homeostasis During Obesity, Wanbao Yang, Wen Jiang, Wang Liao, Hui Yan, Weiqi Ai, Quan Pan, Wesley A Brashear, Yong Xu, Ling He, Shaodong Guo

Faculty, Staff and Students Publications

Estrogen receptor α (ERα) plays a crucial role in regulating glucose and energy homeostasis during type 2 diabetes mellitus (T2DM). However, the underlying mechanisms remain incompletely understood. Here we find a ligand-independent effect of ERα on the regulation of glucose homeostasis. Deficiency of ERα in the liver impairs glucose homeostasis in male, female, and ovariectomized (OVX) female mice. Mechanistic studies reveal that ERα promotes hepatic insulin sensitivity by suppressing ubiquitination-induced IRS1 degradation. The ERα 1-280 domain mediates the ligand-independent effect of ERα on insulin sensitivity. Furthermore, we identify a peptide based on ERα 1-280 domain and find that ERα-derived peptide …

Differential Behavioral Responses In Male And Female Mice Lacking Either Rgs2 Or Rgs4 Proteins After Acute Administration Of Antidepressants And Anxiolytics, Hiroyoshi Matsui, Sarah Seeley, Manoranjan S. D'Souza

ONU Student Research Colloquium

The overall objective of the study was to assess the acute behavioral effects of currently used antidepressants and anxiolytics in male and female mice lacking regulator of G protein-signaling (RGS) proteins 2 and 4 and their wild-type counterparts. RGS 2 and 4 proteins negatively modulate signaling pathways of G protein-coupled receptors (GPCRs), which play an important role in mediating the effects of monoamine neurotransmitters such as dopamine, norepinephrine, and serotonin. These neurotransmitters in turn play an important role in the action of antidepressant and anxiolytic medications. The study was undertaken because no studies till date have systematically assessed the behavioral …

Effects Of Kappa Opioid Receptor Manipulation On Methamphetamine-Induced Behavioral Sensitization In Adolescent Male And Female Rats, Hiroyoshi Matsui Mr, Sarah Seeley, Manoranjan S. D'Souza

ONU Student Research Colloquium

Methamphetamine abuse amongst adolescents has been on the rise in the United States. In this study, we assessed the effects of manipulation of KORs on methamphetamine-induced behavioral sensitization in adolescent male and female rats. Methamphetamine-induced behavioral sensitization is an animal model to study methamphetamine addiction. Behavioral sensitization usually occurs in animals who have been treated with methamphetamine followed by a period of withdrawal. It is hypothesized that brain circuits are altered during the period of withdrawal after methamphetamine exposure resulting in sensitized (increased) responses to methamphetamine at the end of the withdrawal period. The experiment was conducted over 28 days. …
