The Effects Of Exercise Preconditioning On Focal Ischemic Stroke, Gillian Grohs

Theses and Dissertations--Medical Sciences

Cleaved fragments of the extracellular matrix protein perlecan have been shown to promote neuroprotection and repair after ischemic stroke. The cysteine proteases cathepsin B and L as well as the metalloprotease bone morphogenic protein 1 (BMP-1) are capable of releasing the biologically active C-terminal laminin-like globular domain (LG3) of perlecan. Exercise, a known method of reducing stroke risk and severity, has been shown to increase the expression of some proteases associated with perlecan processing. Using a transient distal middle cerebral artery occlusion (MCAo) model for focal ischemic stroke we show that while 7 days of running only slightly decreased infarct …

Factors Regulating Features Of Metabolic Syndrome, Sonja S. Pijut

Theses and Dissertations--Pharmacy

The collective presence of central obesity, low HDL-cholesterol, and elevated triglycerides, blood pressure, and fasting blood glucose constitutes Metabolic Syndrome (MetS), a disease state that increases the risk of cardiovascular disease (CVD) and Type 2 Diabetes Mellitus (T2DM). Nonalcoholic fatty liver disease (NAFLD), present in up to 90% of obese adults, is also linked to MetS. As in CVD, disruptions in cholesterol metabolism play a contributing role in the development of T2DM and NAFLD. Genes involved in cholesterol synthesis, secretion, and catabolism are diurnally regulated in the liver and adipose. Disruptions in the sleep-wake cycle are thought to potentiate metabolic …

Telomerase Reverse Transcriptase In Atherosclerosis, Hua Qing

Theses and Dissertations--Pharmacology and Nutritional Sciences

Telomerase reverse transcriptase (TERT) is the catalytic subunit of telomerase and the limiting factor for the enzyme activity. The expression of TERT and telomerase activity is increased in atherosclerotic plaques. However, the role of TERT dysregulation during atherosclerosis formation remains unknown.

The work herein first identified a multi-tiered regulation of TERT expression in smooth muscle cells (SMC) through histone deacetylase (HDAC) inhibition. HDAC inhibition induces TERT transcription and promoter activation. At the protein level in contrast, HDAC inhibition decreases TERT protein abundance through enhanced degradation, which decreases telomerase activity and induces senescence. Furthermore, during vascular remodeling in vivo, TERT protein …

Insulin Actions On Hippocampal Neurons, Shaniya Maimaiti

Theses and Dissertations--Pharmacology and Nutritional Sciences

Aging is the main risk factor for cognitive decline. The hippocampus, a brain region critical for learning and memory formation, is especially vulnerable to normal and pathological age-related cognitive decline. Dysregulation of both insulin and intracellular Ca2+ signaling appear to coexist and their compromised actions may synergistically contribute to neuronal dysfunction with aging. This dissertation focused on the interaction between insulin, Ca2+ dysregulation, and cognition in hippocampal neurons by examining the contributions of insulin to Ca2+ signaling events that influence memory formation. I tested the hypothesis that insulin would increase cognition in aged animals by altering Ca2+-dependent physiological mechanisms involved …

Steroidogenesis In The Green Anole Lizard Brain And Gonad, Christine Peek

All Graduate Theses, Dissertations, and Other Capstone Projects

Seasonally breeding animals reproduce during certain times of the year and, subsequently, behaviors, steroid hormone levels, and brain morphology change. The green anole lizard (Anolis carolinensis) is an excellent model to study the regulation of steroid hormone production because they have distinct hormonal and behavioral differences between sexes and seasons. As in other vertebrates, steroidogenesis in anoles is under the control of the hypothalamus-pituitary-gonadal (HPG) axis. We tested the hypothesis that natural variations in steroid hormone levels between sexes and seasons are mediated within the brain and gonad by examining four genes involved in steroidogenesis: StAR, Cyp17α1, HSD17β3, and Cyp19α1. …

Bafilomycin A1 and chloroquine are compounds that inhibit autophagy by targeting the …

The Role Of Hur In Astrocytes In Spinal Cord Injury, Thaddaeus Kwan

All ETDs from UAB

Neuroinflammation is a defining event during the acute phase of spinal cord injury (SCI). The inflammatory cascade is initiated by activated glial cells such as astrocytes and microglia in the milieu of the injured tissue through release of pro-inflammatory cytokines, matrix metalloproteinases, and reactive oxygen species. These soluble factors produce cytotoxicity to neurons and other cells either directly or indirectly by promoting permeabilization of the blood-spinal cord barrier, edema and subsequent ischemia. These factors also serve to recruit and activate additional glia and peripheral immune cells. The mRNAs of many of these soluble factors such as TNFα, IL-1β, CXCL1, and …

The Function Of Protein Kinase Ck2 In Cd4 T Cell Differentiation And Autoimmunity, Sara Ann Gibson

All ETDs from UAB

Protein kinase CK2 is a highly conserved serine/threonine kinase essential for cell viability. CK2 exhibits immense pleiotropy and has well characterized interactions with canonical cytosolic signaling pathways such as PI3K/Akt/mTOR and JAK/STAT. These pathways are critical for CD4+ T cell function, and further are known to be aberrantly active in the T cell-driven autoimmune disease Multiple Sclerosis, but little is known as to how CK2 functions in CD4+ T cells or in the context of autoimmune diseases. The current dissertation examines the understudied T cell-specific functions of CK2 utilizing two approaches, pharmacologic inhibition and genetic deletion. We discovered CK2 to …

Mechanism Of Cytomegalovirus-Induced Mucosal Inflammation, Evida Adiko Dennis

All ETDs from UAB

Cytomegalovirus (CMV) is an opportunistic β-herpesvirus that causes severe mucosal inflammation in recipients of organ and stem cell transplants, HIV-1-infected subjects, and persons with inflammatory bowel disease. The gastrointestinal mucosa is among the most common sites of CMV inflammatory disease, and the inflammatory lesions associated with CMV mucosal infection contain infected macrophages and increased levels of macrophage-derived cytokines, implicating mucosal macrophages in the inflammatory process. Paradoxically, in healthy human intestinal mucosa, macrophages are profoundly down-regulated for pro-inflammatory responses (inflammation anergy) due to stromal TGF-β-induction of Smad signaling and inactivation of NF-κB. To elucidate the mechanism whereby CMV promotes macrophage-mediated mucosal …

Manuscripts, Articles, Book Chapters and Other Papers

Despite HLA allele matching, significant acute GvHD remains a major barrier to successful unrelated donor BMT. We conducted a genome-wide association study (GWAS) to identify recipient and donor genes associated with the risk of acute GvHD. A case-control design (grade III-IV versus no acute GvHD) and pooled GWA approach was used to study European-American recipients with hematological malignancies who received myeloablative conditioning non-T-cell-depleted first transplantation from HLA-A, -B, -C, -DRB1, -DQB1 allele level (10/10) matched unrelated donors. DNA samples were divided into three pools and tested in triplicate using the Affymetrix Genome-wide SNP Array 6.0. We identified three novel susceptibility …

Yap And The Hippo Pathway In Pediatric Cancer., Atif Ahmed, Abdalla D. Mohamed, Melissa Gener, Weijie Li, Eugenio Taboada

Manuscripts, Articles, Book Chapters and Other Papers

The Hippo pathway is an important signaling pathway that controls cell proliferation and apoptosis. It is evolutionarily conserved in mammals and is stimulated by cell-cell contact, inhibiting cell proliferation in response to increased cell density. During early embryonic development, the Hippo signaling pathway regulates organ development and size, and its functions result in the coordinated balance between proliferation, apoptosis, and differentiation. Its principal effectors, YAP and TAZ, regulate signaling by the embryonic stem cells and determine cell fate and histogenesis. Dysfunction of this pathway contributes to cancer development in adults and children. Emerging studies have shed light on the upregulation …

Biochemical And Biophysical Methods For Analysis Of Poly(Adp-Ribose) Polymerase 1 And Its Interactions With Chromatin., Maggie H. Chassé, Uma M. Muthurajan, Nicholas J. Clark, Michael A. Kramer, Srinivas Chakravarthy, Thomas Irving, Karolin Luger

Manuscripts, Articles, Book Chapters and Other Papers

Poly (ADP-Ribose) Polymerase I (PARP-1) is a first responder to DNA damage and participates in the regulation of gene expression. The interaction of PARP-1 with chromatin and DNA is complex and involves at least two different modes of interaction. In its enzymatically inactive state, PARP-1 binds native chromatin with similar affinity as it binds free DNA ends. Automodification of PARP-1 affects interaction with chromatin and DNA to different extents. Here we describe a series of biochemical and biophysical techniques to quantify and dissect the different binding modes of PARP-1 with its various substrates. The techniques listed here allow for high …

Immunodeficiency-Associated Lymphoid Hyperplasia As A Cause Of Intussusception In A Case Of Activated Pi3k-Δ Syndrome., Daniel Mettman, Isabelle Thiffault, Chitra Dinakar, Carol J. Saunders

Manuscripts, Articles, Book Chapters and Other Papers

Activated PI3K-δ syndrome refers to a recently described primary immunodeficiency syndrome consisting of recurrent sinopulmonary infections, lymphadenopathy, mucosal lymphoid aggregates, increased susceptibility to Epstein-Barr virus and cytomegalovirus, and increased incidence of B-cell lymphomas. Variants in PIK3CD, which encodes the phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta isoform, enhance membrane association and kinase activity, resulting in increased signal transduction through the PI3K-Akt pathway. Whole-exome sequencing revealed a pathogenic PIK3CD variant in a patient with history of immunologic impairment, recurrent sinopulmonary infections, and lymphoid hyperplasia presenting as intussusception. This case illustrates that while lymphoid hyperplasia secondary to immunodeficiency is most often unsurprising and …

The Effects Of Perinatal Oxycodone Exposure On The Stress Axis And Neurobehavior, Thitinart Sithisarn

Theses and Dissertations--Physiology

Opiate addiction is now a major public health problem. Pregnant women continue to use opiates during gestation; up to 5.4% of pregnant women report using illicit drugs during pregnancy. Previous studies have shown that perinatal insults and exposure to opiates such as morphine in utero can affect the development of the hypothalamic-pituitary-adrenal (HPA)-axis of the offspring and are associated with higher risk of developing neurobehavioral problems. Oxycodone, a semisynthetic putative kappa opioid receptor and partial mu opioid receptor agonist is now one of the most frequently abused pain killers during pregnancy, however limited data are available regarding whether and how …

Visualizing Morphogenesis With The Processing Programming Language, Avik Patel, Amar Bains, Richard Millet, Tamira Elul

Faculty Publications & Research of the TUC College of Osteopathic Medicine

We used Processing, a visual artists’ programming language developed at MIT Media Lab, to simulate cellular mechanisms of morphogenesis – the generation of form and shape in embryonic tissues. Based on observations of in vivo time-lapse image sequences, we created animations of neural cell motility responsible for elongating the spinal cord, and of optic axon branching dynamics that establish primary visual connectivity. These visual models underscore the significance of the computational decomposition of cellular dynamics underlying morphogenesis.

Radioactive Contamination Of Natural Biological Systems: Oxidative Balance And Genetic Stability, Daniel Einor

Theses and Dissertations

The global demand for nuclear energy grows, and so do the risks of an accidental release of nuclear products into the environment. Therefore, understanding the health and ecological effects of contamination by radionuclides should be of great interest for biomedical specialists and the public. Empirical studies unequivocally show that high doses of ionizing radiation (IR) shift the redox-balance of many biological systems and increase the rates of genetic errors. However, the effects of chronic low doses of radiation vary significantly between tissues and between species. The present dissertation comprises the results of experimental and meta-analytical research of a variety of …
