Genetic And Biochemical Characterizations Of The Capsular Glycosyltransferases In Streptococcus Pneumoniae Serotype 2, David Boyd Anthony James

All ETDs from UAB

The principle objective of this dissertation is to develop a thorough understanding of the genetics and biochemistry of capsule synthesis. Specifically, it involves the identification and characterization of the capsular glycosyltransferases in Streptococcus pneumoniae serotype 2, with investigations into their regulation. S. pneumoniae (the pneumococcus) is a significant human pathogen that has the ability to persist as a commensal and then transition to a virulent state, the latter of which is a major contributor to global morbidity and mortality. The capsular polysaccharide (CPS) of S. pneumoniae is a protective surface structure that plays an integral role in this disease process. …

Marcks Is A Regulator Of Growth, Radiation Sensitivity And Is A Novel Prognostic Factor For Glioblastoma Multiforme, John Jarboe

All ETDs from UAB

Glioblastoma multiforme (GBM) is the most common and deadly primary brain malignancy necessitating improved understanding of GBM biology. In this study, we explore the role of Myristoylated Alanine Rich C-Kinase Substrate (MARCKS) in the context of GBM. We have discovered that the MARCKS protein regulates GBM growth as well as response to radiation therapy through its effects on proliferation, senescence, and DNA repair based on our studies in cell culture and in patient-derived xenograft tumors implanted in mice. Importantly, our analysis of clinical patient data demonstrates that MARCKS is an independent predictor for outcome in GBM patients. Indeed, high MARCKS …

Usp49 And H2b Deubiquitination In Chromatin And Cellular Function, Amanda E. Jones Jan 2013

Usp49 And H2b Deubiquitination In Chromatin And Cellular Function, Amanda E. Jones

All ETDs from UAB

Histones are globular proteins which help package and organize DNA in the eukaryotic nucleus. The four core histones, H2A, H2B, H3 and H4, combine with approximately 146 base pairs of DNA to form a nucleosome, the fundamental unit of chromatin. Post-translational modifications to the C-terminal and N-terminal histone tails regulate chromatin structure and function, and play important roles in transcriptional regulation, replication, DNA damage response, and mRNA processing. Histone H2B ubiquitination is an evolutionarily conserved modification with roles in gene expression and DNA damage repair. In addition, H2B ubiquitination may also regulate mRNA splicing. Here, we identify USP49, a cysteine …

Hard On Your Heart: A Qualitative Description Of Adolescent Prenatal Stress, Candace Clayton Knight Jan 2013

Hard On Your Heart: A Qualitative Description Of Adolescent Prenatal Stress, Candace Clayton Knight

All ETDs from UAB

Introduction: Pregnancy during adolescence is potentially stressful due to the concurrent tasks of navigating the typically tumultuous adolescent stage of development and the life altering experience of pregnancy (Kaye, 2008). There is a growing body of research linking prenatal stress to poor birth and developmental outcomes such as premature birth and low birth weight infants (K. Keenan, Sheffield, & Boeldt, 2007; Mulder et al., 2002), which makes describing the relatively unexplored perceptions and experience of stress during adolescent pregnancy important. The life course framework, with its emphasis on social, environmental, and family risk factors, has implications for reducing disparities among …

Cyclic Gmp Phosphodiesterase As A Novel Target For Colorectal Cancer Chemoprevention, Nan Li Jan 2013

Cyclic Gmp Phosphodiesterase As A Novel Target For Colorectal Cancer Chemoprevention, Nan Li

All ETDs from UAB

Nonsteroidal anti-inflammatory drugs (NSAIDs) display promising antineoplastic activity for colorectal and other cancers, but toxicity from cyclooxygenase (COX) inhibition limits their long-term use for chemoprevention. However, many investigators have concluded that COX-independent mechanisms are responsible for their antineoplastic activity. We previously reported that cyclic guanosine monophosphate phosphodiesterase (cGMP PDE) is a non-COX target of sulindac sulfide (SS). However, the specific isozyme families involved have not been well studied. Here we demonstrate that SS inhibits the growth of colon tumor cells through a novel mechanism involving inhibition of two cGMP degrading isozymes, PDE5 and PDE10, to activate cGMP-dependent protein kinase (PKG). …

Biomimetic Self-Assembled Nanomatrix For Pancreatic Islet Transplantation, Dong-Jin Lim Jan 2013

Biomimetic Self-Assembled Nanomatrix For Pancreatic Islet Transplantation, Dong-Jin Lim

All ETDs from UAB

In an attempt to treat type 1 diabetes, pancreatic islet transplantation (PIT) had been studied, but only 10% of recipients showed maintained insulin independence after 5-year post-islet transplantation, indicating that there remains a constant demand for improving the efficacy of PIT. For a successful PIT, critical factors should be addressed: immune protection, revascularization, and ECM-microenvironment reconstitution. Among them, this study was aimed to develop an ECM mimetic scaffold that reconstitutes the ECM derived microenvironment for an isolated beta cell and islet. A growing body of studies also indicates that the pancreatic ECM is of importance in islet survival and function. …

All ETDs from UAB

SURVEYING THE SERUM PROTEOME FOR BIOMARKERS OF EARLY STAGE PANCREATIC CANCER MICHAEL ROBERT LUDWIG MICROBIOLOGY ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) is a uniformly fatal disease due to its refractory nature to conventional therapies at the time of initial diagnosis. In order to in-crease the curative potential of surgical resection, early detection of organ-confined neoplasia is needed. Currently, no effective diagnostic tools are available to detect early-stage pancreatic ductal lesions termed pancreatic intraepithelial neoplasia (PanIN) or lo-cally invasive, organ-confined disease. One way to identify biomarkers that may be use-ful for the early detection of PDAC is through the study of the …

From Family Violence To Dating Violence: Testing The Dual Pathway Model, Anjana Madan Jan 2013

From Family Violence To Dating Violence: Testing The Dual Pathway Model, Anjana Madan

All ETDs from UAB

Family violence in childhood is an established predictor of later adolescent dating violence. Additional predictors of adolescent dating violence include individual beliefs about violence, peer interactions, aggressive behavior, and cross-gender violence. However, these factors have not been integrated into a single comprehensive model of dating violence development. Thus, using the proposed dual pathway model, the present study examined prospective links between family violence exposure in pre-adolescence; proviolent beliefs, aggression, deviant peer affiliation, and cross-gender violence in early adolescence; and dating violence involvement in late adolescence; as well as examined gender and ethnic differences in these relationships. A sample of 456 …

Non-Random Mutations In Yeast: An Examination Of Yeast Genetics During Selection Cycling, Christopher Mcatee Jan 2013

Non-Random Mutations In Yeast: An Examination Of Yeast Genetics During Selection Cycling, Christopher Mcatee

All ETDs from UAB

The appearance of genomic mutation is generally considered a random process, during which single nucleotide polymorphisms (SNPs) and other DNA alterations are selected and fixed by virtue of beneficial effects on fitness. Recent studies have provided examples of induced mutations in response to stress, including the suggestion of biased SNP formation that favors certain adaptations. This project analyzed the appearance and accumulation of mutations in S. cerevisiae following exposure to two lethal forms of selective pressure. A mutation/reversion cycle was established in which 5-fluoroorotic acid (5-FoA) served as an environmental stress to identify the functional loss of URA3 (a gene …

Characterizing The Roles Of Il-11 And Cd68 In Breast Cancer Bone Metastasis, Erin Mills Mccoy

All ETDs from UAB

The molecular mechanisms regulating the preferential metastasis of breast cancer to bone have not been fully elucidated, but it is hypothesized that local conditions in the bone create an environment conducive to colonization by breast cancer cells and that the breast cancer cells interact directly with cells in the bone. In this dissertation, two goals were pursued: (1) to explore breast cancer secreted interleukin (IL)-11's role on osteoclast function and (2) investigate the expression and potential role of CD68 in breast cancer adhesion to bone. Higher rates of bone metastasis occur in human breast cancer tumors expressing IL-11, a cytokine …

The Effects Of Extremes Of Ph On The Growth And Transcriptomic Profiles Of Three Haloarchaea, Aida Moran-Reyna Jan 2013

The Effects Of Extremes Of Ph On The Growth And Transcriptomic Profiles Of Three Haloarchaea, Aida Moran-Reyna

All ETDs from UAB

The Archaea represent a fascinating domain of life where each species comprises a hybrid of bacterial and eukaryal features. Unfortunately, there have been few investigations of the Archaea and many fundamental questions remain regarding their biochemistry, genetics, and genomics. One reason for this is that few archaea are amenable to detailed experimental analysis; however, a few halophilic archaea (haloarchaea) can be easily manipulated in the laboratory and contain a sequenced genome, allowing for bioinformatics studies, such as recording changes in the transcriptomes. Haloarchaea are found wherever seawater is concentrated above 2 M NaCl and contain a similarly high concentration of …

Microevolution Of Capsule Synthesis Genes Contributes To Pneumococcal Capsule Diversity, Melissa Beth Oliver Jan 2013

Microevolution Of Capsule Synthesis Genes Contributes To Pneumococcal Capsule Diversity, Melissa Beth Oliver

All ETDs from UAB

Streptococcus pneumoniae (pneumococcus) is an important human pathogen that expresses a capsular polysaccharide (PS) to shield underlying antigenic structures from complement-mediated opsonophagocytosis. Thus, capsular PS is the major virulence factor, the target of primary immune responses to pneumococcal infections, and the antigenic component of pneumococcal vaccines. Pneumococci have diverse capsular PS synthesis (cps) loci and express over 90 different capsule types. Such diversity helps pneumococci escape immune detection and adapt to changing environments. Recombination of cps genes has been recognized as the main driver of capsule diversity. However, we show point mutations in cps genes encoding glycosyltransferases can broaden enzymes' …

Msx1 Mutations And Their Binding Interactions, Divakar Prakash

All ETDs from UAB

Orofacial clefting (OFC), also called cleft lip and/or palate, is the most common congenital birth anomaly that involve the craniofacial region in humans. The etiology of Non-Syndromic OFC (NS-OFC) is complex and multifactorial; a slew of genetic mutations, standing alone or in combinations, along with several environmental factors, play a major role in the disease process. Numerous linkage and association studies in humans, as well as expression studies and knockout mouse models, have implicated Muscle segment homeobox gene 1 (MSX1), which encodes a homeodomain/DNA binding domain (HD) containing transcription factor as a strong candidate contributing to NS-OFC and Tooth Agenesis …

Plant Selection, Community Dynamics, Ecophysiology, And Stormwater Mitigation On Green Roofs In The Southeastern U.S., Julie G. Price

All ETDs from UAB

Green roofs offer the opportunity to transform impervious surfaces into multifunctional constructed ecosystems. Plant selection for green roofs is often limited to drought-tolerant succulent species, but more diverse assemblages enhance habitat and biodiversity in urban areas and have the potential to improve green roof performance. Nineteen taxa were evaluated under irrigated and non-irrigated conditions over three growing seasons. Individual taxa were evaluated for survival and amount and mechanism of colonization, and the effect of irrigation on plant community structure and vegetation coverage was examined. Only succulent species survived under non-irrigated conditions. Irrigated plots had more taxa, higher diversity index, less …

The Role Of Complement In Experimental Cerebral Malaria, Theresa N. Ramos Jan 2013

The Role Of Complement In Experimental Cerebral Malaria, Theresa N. Ramos

All ETDs from UAB

Cerebral malaria (CM) is one of the most severe clinical complications of P. falciparum malaria with a fatality rate of 15-30%, and 10% of CM survivors have permanent neurological sequelae. Since inflammation is a central pathophysiological tenet of CM, we began examining the role of the complement system in pathogenesis of experimental cerebral malaria (ECM) using Plasmodium berghei ANKA (PbA) model. Previous studies using this model indicated that mice naturally deficient in complement component C5 were protected from cerebral complications, and wild type mice treated with anti-C5aR antibody were also protected. To determine the protective mechanism of naturally-C5 deficient mice, …

Environmental exposures such as diet, use of antibiotics, and lifestyle have significant impact on the health of an individual. One mechanism that acts as a major pathway in these environmental exposures is the role intestinal commensal microbiota play in both metabolic and immunological responses. Metabolic pathways are altered through changes in metabolites provided by commensal microbiota; alterations in microbial make-up can have drastic impacts on metabolic function. Similarly, the development and maturation of the immune system is dependent on the intestinal microbes to induce tolerance and act as both an immune modulator as well as a barrier against pathogens.

Characterization Of The Mumps Virus Replicase, Robert Marsden Cox Jan 2013

Characterization Of The Mumps Virus Replicase, Robert Marsden Cox

All ETDs from UAB

Negative strand RNA viruses (NSV) are unique because their nucleocapsids are used directly as the template for both transcription and replication. The viral genomic RNA is coated by the nucleoprotein (N) for the entirety of the NSV replication cycle. The viral polymerase, which is composed of the L and P proteins, can only recognize encapsidated RNA as the template for RNA synthesis. Our previous studies have solved the EM structure of the MuV N-RNA complex at 25Ņ. This structure revealed how the nucleocapsid is assembled and provides an initial model for examining how the viral polymerase may recognize the …
