Masters
Steroid hormones, such as oestrogen, mediate their effects via activation of oestrogen regulated genes using nuclear receptors. Selective oestrogen receptor modulators (SERMs), such as Tamoxifen, are used to treat oestrogen responsive breast cancers, hctioning to act as oestrogen antagonists, preventing the oestrogen receptor biding DNA and blocking gene expression. However, Tamoxifen has been identified as an oestrogen agonist in other tissues which can often lead to secondary tumors in the years following the treatment. Identification of the genomic regions where SERMs can act as oestrogen agonists can possibly lead to the development of gene targeted therapies or other alternatives to …

Background The existence of multiple subsets of chronic lymphocytic leukemia expressing ‘stereotyped’ Bcell receptors implies the involvement of antigen(s) in leukemogenesis. Studies also indicate that ‘stereotypy’ may influence the clinical course of patients with chronic lymphocytic leukemia, for example, in subsets with stereotyped IGHV3-21 and IGHV4-34 B-cell receptors; however, little is known regarding the genomic profile of patients in these subsets. Design and Methods We applied 250K single nucleotide polymorphism-arrays to study copy-number aberrations and copy-number neutral loss-of-heterozygosity in patients with stereotyped IGHV3-21 (subset #2, n=29), stereotyped IGHV4-34 (subset #4, n=17; subset #16, n=8) and non-subset #2 IGHV3-21 (n=13) and …

Red blood cells (RBC) and reticulocyte parameters were determined on peripheral blood from a subset of patients enrolled in the multicenter study of hydroxyuea (HU) in sickle cell anemia. Multiple blood samples were obtained every 2 weeks. Cellular indices were measured by flow cytometry. Generalized linear models were used to determine the relationship between the longitudinal trajectories of RBC and reticulocyte indices and HU usage. There was a significant relationship between HU usage and most of the RBC and reticulocyte indices. Hydroxyurea produced higher value trajectories than those generated by placebo usage for the hemoglobin (Hb) content of both the …

• This report explores the proposition that teaching effectiveness can be enhanced by accommodating the key differences between two complementary and deeply engrained modes of reality testing, each predominantly centered in different hemispheres of the brain. • (1) Correspondence involves “reality-testing” of a percept, the cerebral representation of an experience in the world. • (2) Coherence involves “textualizing”, that is, reality-testing of a percept by how easily it relates to previous and ongoing parallel and collateral experiences. • Confidence in the validity of any percept throughout development is related to the interplay of these key processes. • As organisms develop, …
Evolution Of Pneumococcal Serogroup 6, 2010 University of Alabama at Birmingham
Evolution Of Pneumococcal Serogroup 6, Preston Eugene Bratcher
All ETDs from UAB
Serogroup 6 of Streptococcus pneumoniae has been known to contain three serotypes, named 6A, 6B and 6C, with highly homologous capsule gene loci. The 6A and 6B capsule gene loci consistently differ from each other by only one nucleotide in the wciP gene. The 6A capsule gene locus has a galactosyltransferase (wciNα), which has been replaced with a glucosyltransferase (wciNß) in the 6C capsule gene locus. We considered that a new serotype, 6D, would be possible if the glucosyltransferase found in 6C strains was combined with the wciP gene from a 6B strain. We demonstrate that this gene combination yields …

The Effects Of Environmental Ozone Exposure On Vascular Function, Oxidative Stress, And Atherosclerosis, Gin Chuang
All ETDs from UAB
Exposure to air pollutants are known to induce airway inflammation, decrease lung function, and worsen existing pulmonary conditions such as asthma. Additionally, air pollutant exposure has also been shown to impact cardiovascular health. Although these pollutant-induced cardiovascular effects were considered to be mediated by the direct action of pollutants upon the cardiovascular tissue and/or the indirect release of pro-inflammatory factors into the circulation, the relative contribution of the two pathways remained equivocal. Recently, several epidemiology studies associated ozone exposure with cardiovascular mortalities. However, relatively few studies to date have examined ozone in this context. In order to address our hypothesis …

Mechanisms Of Major Outer Membrane Protein (Momp)-Vaccine Induced Protective Immunity Against Chlamydia Muridarum Genital Infection, Christina M. Farris
All ETDs from UAB
Urogenital infection with Chlamydia trachomatis is the most common bacterial sexually transmit-ted disease with an estimated 90 million new infections occurring each year worldwide. In women infection with C. trachomatis can result in serious complications including ectopic pregnancy, pelvic inflammatory disease and tubal factor infertility. Despite very effective antimicrobial chemotherapy, control of the infection will likely require an effective vaccine. We have assessed the protective effect of an outer membrane based vaccine using a murine model of chlamydial genital tract infection. Female mice were vaccinated with C. muridarum major outer membrane protein (MOMP) plus the immunostimulatory adjuvants CpG-1826 and Montanide …

The Contribution Of Different Mechanisms Of Viral Sequence Variation To The Evolution Of Positive-Sense Single-Stranded Rna Viruses, Brett Earl Pickett
All ETDs from UAB
The Flaviviridae family of positive-sense single-stranded RNA (+ssRNA) viruses includes viral taxa which greatly impact public health worldwide. To explore how the viruses within the Flaviviridae family evolve, we examined the extent to which these viral taxa use nucleotide covariance, spontaneous mutation, and/or homologous recombination to vary their genotype as well as the resulting phenotype. We developed and used CovarView to assist us in simultaneously viewing and inspecting the results from whole genome covariance analyses. This resulted in the identification of previously-characterized RNA functional structures in the genomes of hepatitis C virus (HCV), as well as a new RNA functional …
In Vitro Elucidation Of The Role And Mechanism Of Rankl In Tnf-And Il-1-Mediated Osteoclast Formation And Function, 2010 University of Alabama at Birmingham
In Vitro Elucidation Of The Role And Mechanism Of Rankl In Tnf-And Il-1-Mediated Osteoclast Formation And Function, Joel Jules
All ETDs from UAB
The receptor activator of NF-қB (RANK) ligand (RANKL) and its receptor RANK play a critical role in osteoclast biology. RANK has three tumor necrosis factor receptor associated factor (TRAF)-binding motifs [PFQEP369-373 (Motif 1), PVQEET559-564 (Motif 2), and PVQEQG604-609 (Motif 3)] that regulate osteoclast formation and function. RANK also contains a TRAF-independent motif (IVVY535-538) that commits bone marrow macrophages (BMMs), which are osteoclast precursors, to the osteoclast lineage for osteoclastogenesis. Notably, tumor necrosis factor-α (TNF) and interlukin-1 (IL-1) utilize TRAFs to initiate most of the signaling pathways known to be activated by RANKL but fail to form osteoclasts unless attended by …
Structural And Functional Study Of P58(Ipk), 2010 University of Alabama at Birmingham
Structural And Functional Study Of P58(Ipk), Jiahui Tao
All ETDs from UAB
P58(IPK) is an endoplasmic reticulum (ER)-resident protein which is upregulated during unfolded protein response (UPR). In stressed cells, P58(IPK) functions to restore protein folding equilibrium in ER by suppressing protein aggregation and promoting protein folding. P58(IPK) associates with the unfolded protein via its N-terminal TPR domain and presents it to BiP (binding immunoglobulin protein) for subsequent folding. P58(IPK) belongs to the Hsp40 family. Collectively, P58(IPK) is a stress-inducible ER-resident molecular chaperone. In this dissertation, we report the crystal structure of P58(IPK) TPR domain to 2.5 Å resolution. In the crystal structure, the 43-kDa TPR domain consists of nine tandemly linked …

Heparanase Drives The Aggressive Myeloma Phenotype: Preclinical Development Of A Heparanase Inhibitor For The Treatment Of Multiple Myeloma, Joe Ritchie
All ETDs from UAB
Heparanase, an endoglycosidase which cleaves heparan sulfate chains at specific sites, is rarely expressed in normal tissues but becomes evident in many human cancers. We have previously shown that heparanase promotes myeloma growth and angiogenesis through modulation of the tumor microenvironment. Recognition that heparanase drives the aggressive myeloma phenotype has led to new strategies designed to therapeutically target this enzyme. SST0001, a non-anticoagulant heparin that is 100% N-acetylated and 25% glycol split, was previously described as a potent inhibitor of heparanase activity in vitro, and, in limited in vivo experiments, SST0001 was identified to have efficacy as an anti-tumor agent …
Roles Of Adiponectin And Its Receptors In Foam Cell Transformation, 2010 University of Alabama at Birmingham
Roles Of Adiponectin And Its Receptors In Foam Cell Transformation, Ling Tian
All ETDs from UAB
Macrophages play a critical role in the initiation and progression of atherosclerosis by producing pro-inflammatory mediators and transforming into lipid-laden foam cells. The prevention of lipid accumulation and inflammation in macrophage foam cells, therefore, represents a promising target for effective therapy for atherosclerosis. Adiponectin is a circulating cytokine primarily expressed and secreted by adipocytes, and is downregulated in obesity-linked diseases including type 2 diabetes, coronary artery disease and hypertension. In oxidized low-density lipoprotein (oxLDL)-induced human THP-1 macrophage foam cells, adiponectin suppresses lipid accumulation through decreasing lipid uptake and increasing high-density lipoprotein (HDL)-mediated lipid efflux. The potential mechanisms that adiponectin utilizes …
Usp14: A Link Between The Proteasome And Synaptic Function, 2010 University of Alabama at Birmingham
Usp14: A Link Between The Proteasome And Synaptic Function, Brandon John Walters
All ETDs from UAB
The ubiquitin proteasome system (UPS) is a coordinated process by which the cell can control protein distribution and abundance. Proteins are marked for turnover by the construction of a polyubiquitin chain on the protein substrate. Once engaged by the proteasome, the ubiquitin side-chain is disassembled by proteasomal deubiquitinating enzymes (DUBs), preventing entry of ubiquitin into the proteasome and recycling it for use in future reactions. One of the DUBs that resides on the proteasome is Ubiquitin Specific Protease 14 (Usp14), which is mutated in the ataxia (axJ) mice. This mutation results in pronounced physical deficits and, unexpectedly, a deficit in …
The Structural And Functional Studies Of Yeast Nucleotide Exchange Factor Sil1p And Its Complex With Bip, 2010 University of Alabama at Birmingham
The Structural And Functional Studies Of Yeast Nucleotide Exchange Factor Sil1p And Its Complex With Bip, Ming Yan
All ETDs from UAB
Sil1 is an Endoplasmic Reticulum (ER) localized protein. SIL1 was initially identified as a UPR-regulated gene. Later studies show Sil1 functions as the nucleotide exchange factor of ER lumenal Hsp70--Bip by directly interacting with the ATPase domain of Bip. Currently, the molecular mechanism how Sil1 catalyzes nucleotide exchange of Bip is still elusive. In this study we determine the complex structure of yeast S.cerevisia Sil1 and Bip (also called Kar2) ATPase domain at 2.3Ã resolution by Single-anomalous dispersion (SAD) methods. The Sil1-Bip complex structure reveals that one sil1 molecule interacts with one Bip ATPase domain molecule to form the complex. …
