Human cytomegalovirus (HCMV) is a ubiquitous pathogen that infects over 50% of the world’s population. HCMV infection is asymptomatic in healthy individuals, however can cause severe morbidity and mortality in individuals with compromised innate or adaptive immunity. As a complex virus that has been known for about 70 years, we are still in search of vaccines or effective treatments against it. HCMV genome encodes over 175 open reading frames with the function of majority proteins remains to be defined. A unique feature of HCMV among herpesvirus is the reorganization of cellular secretory pathway and membranes to form assembly compartment (AC). …

Race, Type Ii Diabetes Mellitus And Vertebral Fragility Fractures: A Cross-Sectional Analysis From Nhanes, Yuchen At Xiao Jan 2020

Race, Type Ii Diabetes Mellitus And Vertebral Fragility Fractures: A Cross-Sectional Analysis From Nhanes, Yuchen At Xiao

All ETDs from UAB

IntroductionThis study examined the association between race and bone health, and if T2DM modifies this association in a diverse sample of adults. Methods We conducted a cross-sectional study using the 2013-2014 National Health and Nutrition Examine Survey (NHANES) data. Bone health outcomes included lumbar spine BMD (lowered BMD based on T-scores <-1), and vertebral deformities, assessed via vertebral fracture assessment (VFA), including presence, number of deformities, and severity ratio of deformities. T2DM status and other demographic, lifestyle, and health characteristics were self-reported via questionnaire data. To assess if T2DM modifies the association between race and bone health outcomes, we conducted stratified analyses using logistic regression for dichotomous outcomes, Poison regression for count outcomes, and linear regression for continuous outcomes. Results Non-Hispanic (NH) Blacks have significantly less odds of being lowered BMD and osteoporosis comparing to NH-Whites in the crude model and significantly less odds of having vertebral deformities comparing to NH-White in both crude and adjusted model for non-diabetic participants. Such differences are not observed in diabetic groups. Participants in Other race group have significantly more odds of being lowered BMD comparing to NH-Whites in the adjusted model for both diabetic and non-diabetic groups. And have significantly more odds of having vertebral deformities in the diabetic group, crude and adjusted, yet the differences are not significant in non-diabetic groups. Similar results were seen in the number of deformities and total bone loss ratio. The potential modification effect of T2DM was not significant in these models. Conclusions In our national evaluation, bone health differs not only by race and ethnic group but also by T2DM status. The protective vertebral fragility effects observed among NH-Blacks was no longer present among those with diabetes. Likewise, among participants in other racial and ethnic groups, T2DM seemed to magnify the association of worse vertebral fragility. Such trends indicate a potential modifying effect of participants’ T2DM status and should be noted clinically, yet more studies are required for more precise results.

Circadian Control Of Blood Pressure And Renal Electrolyte Excretion, Dingguo Zhang Jan 2020

Circadian Control Of Blood Pressure And Renal Electrolyte Excretion, Dingguo Zhang

All ETDs from UAB

Many physiological processes, including blood pressure (BP) regulation, follow specific rhythms tied to a 24-h cycle. This is largely because circadian genes operate in virtually every cell type in the body. In healthy individuals, BP during nighttime is 10-20% lower compared to daytime, a phenomenon known as “nocturnal dipping”. It is acknowledged that the dipping of BP is essential in maintaining normal cardiovascular and renal function. However, it remains unclear as to what factors contribute to nocturnal dipping. The purpose of this dissertation is to elucidate mechanisms underlying the circadian rhythm of BP. Bmal1 is one of the core circadian …

Exploring The Mechanism Of Cleavage And Secretion Of The Major Sperm Protein (Msp) Domain Of The Vapb/Vpr-1 Protein, Hala Zein-Sabatto Jan 2020

Exploring The Mechanism Of Cleavage And Secretion Of The Major Sperm Protein (Msp) Domain Of The Vapb/Vpr-1 Protein, Hala Zein-Sabatto

All ETDs from UAB

VAPB is one of three mammalian VAP proteins. It is a type-II ER transmembrane protein whose N-terminal major sperm protein domain (MSPd) is cleaved and secreted. Since the MSPd faces the cytosol, rather than the ER lumen, how it is cleaved and secreted is not yet known. In humans, P56S is a substitution mutation within the VAPB protein that segregates with cases of familial Amyotrophic Lateral Sclerosis (ALS) and prevents the secretion of VAPB MSPd. The work described in this thesis uses C. elegans to study how the N-terminal MSPd of VAPB is proteolytically processed, secreted, and regulated. C. elegans …

Toward The Mechanism Underlying Latanoprost- And Benzalkonium Chloride-Induced Meibomian Gland Dysfunction In Patients Treated For Glaucoma, Jillian Ziemanski

All ETDs from UAB

Once thought to be no more than a vexing eye condition, ocular surface disease (OSD) is now being viewed as a differentiating factor between sight and no sight. In the setting of glaucoma, OSD can interfere with treatment success, potentially allowing the visually devastating pathology of glaucoma to plow onward with little restraint. Compounding the clinical challenge is the growing awareness that glaucoma-associated OSD appears to be iatrogenically induced by topical ophthalmic medications. Daily, topical instillation of preserved prostaglandin analogs (PGAs), the most common first-line treatment for glaucoma, has been linked to a variety of OSD subtypes, including meibomian gland …

Obesity manifests physiologically in multiple organ systems of the body, typically increasing the risk of developing cardiometabolic disorders. Researchers have questioned the causative role that western dietary patterns have on disease pathogenesis and have speculated that quality and quantity of dietary fats and/or carbohydrates have a predictive role in the development of these disorders. Standard reference diets such as the AIN-93 rodent diet have historically been used to promote optimal animal model health and reduce variation of results across experiments. These diets have been invaluable to murine research; however, their translational value in studying human nutrition-related pathologies is limited. Early …

Lim Transcriptional Complexes That Impact Endocrine Pancreas Development And Function, Maigen Bethea

All ETDs from UAB

The Ldb1:Isl1 LIM transcriptional complex is critical for endocrine pancreas development as well as b-cell terminal differentiation. These complexes have been shown to interact with various proteins to elicit transcriptional regulation in other tissues, yet few interactors have been identified in b-cells. Therefore, the objective of this dissertation was to identify interactors of Ldb1 and Isl1 and assess their contributions to endocrine pancreas development and function. Using a reversible crosslink immunoprecipitation (ReCLIP) and mass spectrometry (MS) strategy to isolate endogenous Ldb1 and/or Isl1 interacting protiens, SSBP3, Rnf20, and Rnf40 (E3 ubiquitin ligases) coregulators were identified. SSBP3 was found to interact …

Transcriptional, Translational, And Enzymatic Metabolic Regulation By L-2 Hyroxyglutarate, Garrett Brinkley Jan 2020

Transcriptional, Translational, And Enzymatic Metabolic Regulation By L-2 Hyroxyglutarate, Garrett Brinkley

All ETDs from UAB

Recent studies have identified elevated levels of a small metabolite, L-2 Hydroxyglutare (L-2HG), which curiously has no known metabolic roles. Renal tumors, hypoxia as well as larval development, specifically in Drosophila, all have been identified to have high levels of L-2HG. These broad categories suggest L-2HG has a physiological role. This work uncovers the impact of elevated levels of L-2HG in altering normal kidney and renal tumors. With structural similarity to α-Ketoglutarate (αKG), L-2HG acts as a competitive inhibitor to enzymes that utilize αKG as substrates or co-factors. L-2HG is known to be metabolized by L-2HG dehydrogenase (L2HGDH). Loss of …

Restless Legs Syndrome And Multiple Sclerosis: The Possible Role Of Physical Activity For Managing Symptoms, Katie Cederberg Jan 2020

Restless Legs Syndrome And Multiple Sclerosis: The Possible Role Of Physical Activity For Managing Symptoms, Katie Cederberg

All ETDs from UAB

Restless legs syndrome (RLS) is an idiopathic neurological disorder characterized by unpleasant sensations in the legs that affects 26% of persons with multiple sclerosis (MS). The current pharmacological treatments for RLS are associated with a number of side effects, including the worsening of symptoms (i.e., augmentation). Physical activity represents a promising, behavioral approach for managing symptoms of RLS in MS. To date, physical activity has demonstrated tremendous benefits for managing many consequences of MS, but there is no evidence on its efficacy for managing RLS in MS. This dissertation described the current literature regarding physical activity and RLS in adults …

Distinct Tissue Specific Functions Of Bone Marrow Regulatory T Cells, And Their Therapeudic Applications In Myeloid Neoplasms, Virginia Camacho Jan 2020

Distinct Tissue Specific Functions Of Bone Marrow Regulatory T Cells, And Their Therapeudic Applications In Myeloid Neoplasms, Virginia Camacho

All ETDs from UAB

In the bone marrow, Regulatory T cells (Tregs) constitute nearly 30% of CD4+ T cells, a significantly higher ratio than other tissues. Although a few of the mechanisms by which Tregs regulate normal hematopoiesis have been elucidated, our understanding of this process during leukemogenesis is ex-tremely limited. In this work, we define how Tregs maintain and support the bone marrow microenvironment. We propose that the role of Tregs extends be-yond their canonical immuno-suppressive function and that these cells are re-quired to maintain healthy hematopoiesis. We have defined tissue-specific roles for Tregs in the bone marrow including the maintenance of hematopoietic …

Abnormalities In The Akt-Mtor Signaling Pathway In The Dorsolateral Prefrontal Cortex In Schizophrenia, Radhika Chadha Jan 2020

Abnormalities In The Akt-Mtor Signaling Pathway In The Dorsolateral Prefrontal Cortex In Schizophrenia, Radhika Chadha

All ETDs from UAB

Schizophrenia (SZ) is a complex and heterogeneous mental illness in which myriad changes across multiple neurotransmitter systems (dopamine, serotonin, GABA, glutamate, and others) have been reported. Numerous regulatory mechanisms have been explored in SZ research and rather than being a disorder of one specific neurotransmitter pathway, SZ may instead be a disturbance of intracellular signaling processes that underlie the regulation of these systems. The AKT-mTOR signaling cascade plays an important role in core cellular processes of cell growth, metabolism and survival and is one such potential candidate. Abnormalities in AKT expression and activity have been consistently implicated in SZ pathophysiology …

From Pathology To Circuits: Loss Of Pink1 Function In Parkinson’S Disease, Rose Berthe Creed

All ETDs from UAB

Parkinson’s disease (PD) is the most common neurogenerative motor disorder, affecting over 10 million people worldwide. Clinically, PD is diagnosed by presentation of hypokinetic movements such as bradykinesia, rigidity, and resting tremor. Additionally, PD patients have non-motor symptoms that include anosmia, constipation, and hypophonia. Current therapeutics have been successful in treating many of the locomotor symptoms, however no therapies stop or slow disease progression and the effectiveness of current medications diminishes as the symptoms invariably become more severe over the course of many years. Histopathologically, PD diagnosis is confirmed postmortem by two pathological hallmarks: 1. loss of dopaminergic neurons in …

Impact Of Diet And Meal Timing On Time-Of-Day Dependent Hippocampal Function, Jennifer Davis Jan 2020

Impact Of Diet And Meal Timing On Time-Of-Day Dependent Hippocampal Function, Jennifer Davis

All ETDs from UAB

Circadian rhythms are biological processes that cycle every ~24 hours and have allowed life to adapt for optimal function across the day. These rhythms are present in all tissues in the body and are coordinated to the light/dark cycle by the suprachiasmatic nucleus (SCN) in the hypothalamus. Along with active-rest cycles, cognitive performance fluctuates across the course of the day, peaking during the active phase. In addition to the light cycle, food and meal timing can provide signaling cues to extra-SCN tissues. Food access only during the inactive phase results in weight gain and memory impairment. High fat diet protocols …

Glaucoma is the second leading cause of blindness and third leading cause of visual impairment worldwide; 180 million people suffer from a glaucomatous visual disability. Glaucoma is an ocular neurodegenerative disease with several risk factors. The major identified risk factors of glaucoma are intraocular pressure (IOP), age, race, central cornea thickness, family history, and low diastolic blood pressure. The lowering of IOP is the only modifiable risk factor for the disease. However, we know little about the true character of IOP. Periodic IOP measurements are obtained every few months or at the discretion of the clinician during office hours and …

Hypoxia within solid tumors presents as a barrier to the effectiveness of cancer treatment. Hypoxia has been implicated in cancer cell resistance to standard therapies used in the clinic to treat breast cancer. Additionally, the treatment resistance mechanisms in cancer cells are exacerbated by oncogenic pathways that enable adaptation to the hypoxia and facilitate therapy resistance. Cancer cells often co-opt signaling pathways essential for embryonic development as a defense against cellular attacks. Hedgehog (Hh) signaling pathway is one of such embryonic development pathways that have been implicated in mitigating cancer growth, metastasis, and resistance to therapy. Hh signaling pathway promotes …

While there has been an increase in refugees worldwide over the past several years, some groups, namely Palestinian refugees, have been refugees since their expulsion from Palestine in 1948. Many countries have accepted and allowed Palestinian refugees to integrate into their societies, both socially and economically, but Palestinian refugees in Lebanon are not granted many basic rights. One of these is the right to employment, which has been heavily restricted by the Lebanese government. While policy reports have described the detrimental ramifications of this lack of access to employment on Palestinian refugees’ livelihood, almost none of these have documented Palestinian …

Parent Reactions To Sexual And Gender Identity Disclosure Events In The Deep South, Allison Claire Estep Jan 2020

Parent Reactions To Sexual And Gender Identity Disclosure Events In The Deep South, Allison Claire Estep

All ETDs from UAB

Disclosure of sexuality by coming out is a central part of the process of self-identification for LGBT youth (Denes & Afifi, 2014). Parents’ initial response to their child’s coming out is linked to parent-child relationship satisfaction and if the child will later feel the need to come out for a second time or to clarify their sexual identity (Denes et al. 2014). Parental acceptance of LGBT youth’s disclosure has been linked to higher self-esteem and lower rates of suicidal tendencies, depression, and substance abuse (Needham & Austin, 2010; Ryan, Russell, Huebner, Diaz, & Sanchez, 2010). Current research regarding parent reactions …

Public Participation As Peacebuilding: A New Model For Environmental Justice Communities, Kathryn E. Fagan Jan 2020

Public Participation As Peacebuilding: A New Model For Environmental Justice Communities, Kathryn E. Fagan

All ETDs from UAB

Environmental justice seeks to address the unequal burden of environmental problems experienced by minority and low-income communities and to ensure their meaningful participation in decision-making processes. While there is increasing attention being paid to the unequal distribution, there is a lack of work that focuses explicitly on public participation in an environmental justice context. Environmental problems, in general, are complex and involve a variety of stakeholders, and environmental justice problems are further complicated by the interconnections of structural racism, historical trauma, and damaged relationships. Many of these complexities can be seen in the ongoing efforts at the 35th Avenue Superfund …

Assessment Of Neuropsychological Outcomes After Traumatic Brain Injury And Association With Early Orientation Performance, Christina Diblasio

All ETDs from UAB

Moderate-severe traumatic brain injury (TBI) is a leading cause of permanent disability, and cognition plays a critical role in overall function and life after TBI. Moderate-severe TBI often creates long-term deficits in the domains of attention, processing speed, memory, and executive function. Given the prevalence of cognitive deficits following injury and the debilitating effects these deficits can have on functioning, it is important to monitor cognition directly following injury and across recovery. Routine cognitive assessment is essential in order to identify deficits, track recovery, and better guide rehabilitation and educational efforts. It is also critical to identify accurate and feasible …

All ETDs from UAB

Autoimmunity is propagated through the lack of effective mechanisms of central and peripheral tolerance. In relapsing remitting multiple sclerosis (RRMS), dysregulated adaptive immune cells have been shown to contribute to disease morbidity through the influence of immune-modulating cytokines in the peripheral blood. Interleukin-2 (IL-2) is a cytokine with several key functions in regulating homeostatic mechanisms within the human immune system. Interferon gamma (IFNγ) is a type II interferon that is needed for an effective response to intracellular bacteria infection through the actions of Th1 cells. IL-2 and IFNγ signaling occurs primarily through signal transducer and activator of transcription (STAT) activation. …

Noninvasive Neuromodulation Using A Benchtop Approach To Mri-Guided Focused Ultrasound Blood Brain Barrier Opening, Megan Rich

All ETDs from UAB

Fundamental neuroscience research has provided a deeper understanding of the genes, molecules and cellular circuitry involved in neurological disorders, however translating discovery into clinical application remains a major challenge. This bench to bedside gap is in part due to the discrepancy in techniques used in the laboratory vs. the clinic for targeting the mechanisms that underlie disease. Ideally this discrepancy would be resolved not only by implementing novel clinical techniques to provide more precise targeting of disease foci, but also by using the same techniques in the clinic that are used at the lab bench to provide a direct bench …

Exploring The Roles Of Long Non-Coding Rnas In Glioblastoma Tumor Recurrence And Therapy Resistance, Christian Tyler Stackhouse Jan 2020

Exploring The Roles Of Long Non-Coding Rnas In Glioblastoma Tumor Recurrence And Therapy Resistance, Christian Tyler Stackhouse

All ETDs from UAB

ABSTRACT Glioblastoma (GBM) is the most common and devastating primary CNS brain tumor with a median survival time of around 14 months. Most patients succumb to re-current disease which is often more malignant than the primary tumor and is frequently therapy resistant. There have not been significant advances in the treatment of GBM despite decades of research. This is partly due to the lack of accurate preclinical models and of the focus on primary rather than recurrent tumors. We created a 350 gene custom GBM-specific panel which contains 16 molecular signatures including molecular sub-typing signatures. We have demonstrated concordance of …
