Investigating The Roles Of Zinc-Binding Protein (Zbp-89) And Rela (Nfkb-P65) In The Regulation Of Matrix Metalloproteinase 1 (Mmp1) Gene Expression, Nelly Khaselev

PCOM Biomedical Studies Student Scholarship

Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases with the unique ability to breakdown virtually the entire extracellular matrix (ECM). Through ECM remodeling, MMPs play an important role in normal development, tissue repair, angiogenesis, and apoptosis. Studies have shown that unregulated MMP expression plays a role in many cancers and chronic inflammatory diseases. Previous research has used gene sequence analysis ofthe MMP-1 promoter to identify a putative ZBP-89 binding site at -1969 bp. Chromatin immuneprecipitation experiments showed that both ZBP-89 and Re!A (p65) could bind to this binding site. In this thesis research, transfection experiments were used to explore …

Voxel Based Morphometry In Optical Coherence Tomography: Validation & Core Findings, Bhavna J. Antony, Min Chen, Aaron Carass, Bruno M. Jedynak, Omar Al-Louzi, Sharon D. Solomon, Shiv Saidha, Peter Calabresi, Jerry L. Prince

Mathematics and Statistics Faculty Publications and Presentations

Optical coherence tomography (OCT) of the human retina is now becoming established as an important modality for the detection and tracking of various ocular diseases. Voxel based morphometry (VBM) is a long standing neuroimaging analysis technique that allows for the exploration of the regional differences in the brain. There has been limited work done in developing registration based methods for OCT, which has hampered the advancement of VBM analyses in OCT based population studies. Following on from our recent development of an OCT registration method, we explore the potential benefits of VBM analysis in cohorts of healthy controls (HCs) and …

Inhibition Of Bacterial Growth And Prevention Of Bacterial Adhesion With Localized Nitric Oxide Delivery, Julia Osborne

Dissertations, Master's Theses and Master's Reports

Bacterial infections continue to be a problem at the site of an indwelling medical device, and over the years, various bacterial strains have become more resistant to current antibiotic treatments. Bacterial infection at an indwelling medical device can be dangerous and affect the performance of the medical device which can ultimately lead to the failure of the device due to bacterial resistance to treatment.

Nitric Oxide (NO) has been shown to possess antibacterial properties to prevent and inhibit bacterial growth. NO releasing coatings on indwelling medical devices could provide a reduction in bacterial infections that occur at the device site …

Interplay Between Her2, Parp1, And Nf-Κb In Breast Cancer: Potential Therapeutic Implications, Monicka Ewa Wielgos

All ETDs from UAB

We previously reported that HER2+ breast cancers are susceptible to Poly (ADP-Ribose) polymerase inhibitors (PARPi) alone, agents that are efficacious against homologous recombination (HR) deficient tumors. However, this phenomenon was determined to be independent of a HR repair deficiency but rather due to suppression of NF-κB activity and signaling by PARP inhibition. Further, HER2 overexpression itself was necessary and sufficient to confer this susceptibility. Interestingly, PARP1 and phosphorylated RelA/p65 (NF-κB) levels were found to be elevated in human HER2+ breast cancers compared to luminal breast cancers. These data suggest a possible interplay between HER2, PARP1, and NF-κB, and how this …

The Role Of Glutamate In Immune Cell Infiltration And Excitotoxic Mechanisms In Autoimmune Demyelination, Kirsten Scarlett Evonuk

All ETDs from UAB

Multiple sclerosis is the most common neurological disorder in young adults. Current treatments modulate the immune system, but no treatments prevent central nervous system damage. Inflammation occurs even during disease remission, contributing to ongoing damage and resulting in disease progression. The lack of neuroprotective treatments despite continued inflammatory onslaught in the central nervous system indicates the need for therapeutic discovery in this area. One potential therapeutic target is glutamate, whose dysregulation in multiple sclerosis has been implicated in excitotoxic cellular death. Herein we describe the roles of glutamate in multiple sclerosis and explore the blockade of a source of excitotoxic …

Epigenetic Dysregulation In Levodopa-Induced Dyskinesia, David Anthony Figge

All ETDs from UAB

Levodopa-induced dyskinesia (LID) is a persistent behavioral sensitization that develops after repeated levodopa (L-DOPA) exposure in Parkinson disease (PD) patients. LID is characterized by a “priming effect”, whereby initial administrations of L-DOPA trigger a sensitized biochemical and transcriptional response upon subsequent administrations of L-DOPA. In neurons, transcriptional regulation through dynamic changes to epigenetic modifications, including DNA methylation and histone acetylation, have been shown pivotal to many long-term behavioral modifications; however, their role in LID has been minimally explored. Using a rodent model, we show LID development leads to the aberrant expression of DNA demethylating enzymes and locus-specific changes to DNA …

Atp6v1c1 Enhances Breast Cancer Growth By Activating V-Atpase Mediated Mtorc1 Signaling And Metastasis By Increasing V-Atpase Activity In Cancer Cells, Matthew J. Mcconnell

All ETDs from UAB

It is known that the vacuolar ATPase has a number of functions related to tumor growth and progression such as involvement in drug resistance, pH regulation, autophagy, and lysosomal acid protease activation, as well as invasion and metastasis. Here we specifically describe the role of ATP6v1c1 in murine and human models of breast cancer. ATP6v1c1 is the dominant isoform of the coordinating subunit (ATP6v1c) involved in the assembly of the vacuolar ATPase complex which plays a key role in cancer growth and progression. We also describe how ATP6v1c1 knockdown impairs tumor nutrient signaling through mTORC1 and tumor cell proliferation, by …

Coordination Of Rna Polymerase Ii Pausing And 3' End Processing Factor Recruitment With Alternative Polyadenylation, Becky Fusby, Soojin Kim, Benjamin Erickson, Hyunmin Kim, Martha L. Peterson, David L Bentley

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Most mammalian genes produce transcripts whose 3' ends are processed at multiple alternative positions by cleavage/polyadenylation (CPA). Poly(A) site cleavage frequently occurs cotranscriptionally and is facilitated by CPA factor binding to the RNA polymerase II (Pol II) C-terminal domain (CTD) phosphorylated on Ser2 residues of its heptad repeats (YS₂PTSPS). The function of cotranscriptional events in the selection of alternative poly(A) sites is poorly understood. We investigated Pol II pausing, CTD Ser2 phosphorylation, and processing factor CstF recruitment at wild-type and mutant IgM transgenes that use alternative poly(A) sites to produce mRNAs encoding the secreted and membrane-bound forms of …

The Challenge Of Analyzing The Results Of Next-Generation Sequencing In Children., Isabelle Thiffault, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

In recent years, next-generation sequencing technologies have revolutionized approaches to genetic studies. Whole-exome or whole-genome sequencing allows diagnoses in many patients who have complex phenotypes and unusual clinical presentations. As genomic and exomic testing expands in both the research and clinical settings, pediatricians will need to understand the technology of next-generation sequencing and the complexity of interpreting genomic variants relevant to patient phenotypic features. This article briefly explains the technology by which genomes are sequenced and discusses some of the complexity related to interpreting genomic variants. We conclude with some thoughts on the clinical applications of such testing.

Children and adolescents with gender and sex diversity include (1) gender-nonconforming and transgender individuals for whom gender identity or expression are incongruent with birth-assigned sex (heretofore, transgender) and (2) individuals who have differences in sex development (DSD). Although these are largely disparate groups, there is overlap in the medical expertise necessary to care for individuals with both gender and sex diversity. In addition, both groups face potential infertility or sterility as a result of desired medical and surgical therapies. The Ann & Robert H. Lurie Children's Hospital of Chicago (Lurie Children's) gender and sex development program (GSDP) provides specialized multidisciplinary …

Examining The Potential Clinical Value Of Curcumin In The Prevention And Diagnosis Of Alzheimer's Disease, K. G. Goozee, T. M. Shah, Hamid R. Sohrabi, Stephanie Rainey-Smith, B. Brown, Guiseppe Verdile, Ralph Martins

Research outputs 2014 to 2021

Curcumin derived from turmeric is well documented for its anti-carcinogenic, antioxidant and anti-inflammatory properties. Recent studies show that curcumin also possesses neuroprotective and cognitive-enhancing properties that may help delay or prevent neurodegenerative diseases, including Alzheimer’s disease (AD). Currently, clinical diagnosis of AD is onerous, and it is primarily based on the exclusion of other causes of dementia. In addition, phase III clinical trials of potential treatments have mostly failed, leaving disease-modifying interventions elusive. AD can be characterised neuropathologically by the deposition of extracellular β amyloid (Aβ) plaques and intracellular accumulation of tau-containing neurofibrillary tangles. Disruptions in Aβ metabolism/clearance contribute to …

De Vries, Mona Saffarzadeh, Anca Sindriaru, Seppe V. Beken, Meinhard Wlaschek, Mark A. Kluth, Christoph Ganss, Natasha Y. Frank, Markus H. Frank, Klaus T. Preissner, Karin Scharffetter-Kochanek

Research outputs 2014 to 2021

Mesenchymal stem cells (MSCs) are crucial for tissue homeostasis and regeneration. Though of prime interest, their potentially protective role on neutrophil-induced tissue damage, associated with high morbidity and mortality, has not been explored in sufficient detail. Here we report the therapeutic skill of MSCs to suppress unrestrained neutrophil activation and to attenuate severe tissue damage in a murine immune-complex mediated vasculitis model of unbalanced neutrophil activation. MSC-mediated neutrophil suppression was due to intercellular adhesion molecule 1-dependent engulfment of neutrophils by MSCs, decreasing overall neutrophil numbers. Similar to MSCs in their endogenous niche of murine and human vasculitis, therapeutically injected MSCs …

Research outputs 2014 to 2021

We present a pilot study aimed at determining the effects of expression of ATP-binding cassette member B5 (ABCB5), a previously described marker for melanoma-initiating cells, on cellular metabolism. Metabolic profiles for two groups of human G3361 melanoma cells were compared, i.e. wildtype melanoma cells with intact ABCB5 expression (ABCB5-WT) and corresponding melanoma cell variants with inhibited ABCB5 expression, through shRNA-mediated gene knockdown (ABCB5-KD). A comprehensive metabolomic analysis was performed by using proton and phosphorus NMR spectroscopy of cell extracts to examine water-soluble metabolites and lipids. Parametric and non-parametric statistical analysis of absolute and relative metabolite levels yielded significant differences for …

The Hormonal Regulation Of The Claudin Genes In The Ovary, Sean Gadson, April Binder, Kenneth Korach, Katherine Hamilton

All Master's Theses

The ovary is a dynamic organ that responds to many hormonal signals. When these hormonal signals are disrupted, ovarian dysfunction can occur. One such example is Polycystic Ovarian Syndrome (PCOS). PCOS patients suffer from high levels of testosterone. Excess testosterone may misregulate genes in the ovary and disrupt ovarian function. The Claudin (Cldn) 3 and Cldn11 genes have been shown to be regulated by androgens in the testis, while studies in ovarian cancer cells suggests a coregulatory mechanism for the expressions of Cldn3 and Cldn4 in the ovary. The objective of this study was to characterize the hormonal …

Human Oocytes And Embryos Viewed By Time-Lapse Videography, And The Development Of An Embryo Deselection Model, Yanhe Liu

Theses: Doctorates and Masters

Despite its wide application today, in vitro fertilization (IVF) treatment continues to have relatively low efficacy, largely due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse observation of human embryos is gaining increasing popularity due to the more detailed morphokinetic information obtained plus uninterrupted culture conditions. The morphokinetic information enables the use of quantitative timings in developmental milestones of embryos and qualitative measures of abnormal biological events, to assist embryo selection/deselection. This project aimed to identify current limitations in the use of such measures and …
