Multiscale Genomic Analysis Of The Corticolimbic System: Uncovering The Molecular And Anatomic Substrates Of Anxiety-Related Behavior, Khyobeni Mozhui

Theses and Dissertations (ETD)

Genetic diversity generates variation at multiple phenotypic levels, ranging from the most basic molecular to higher-order cognitive and behavioral traits. The far-reaching impact that genes have on higher traits is apparent in several neuropsychiatric conditions such as stress and anxiety disorders. Like most, if not all, neural phenotypes, stress, anxiety, and other emotion-related traits are extremely complex and are defined by the interplay of multiple genetic, environmental, experiential, and epigenetic factors.

The work presented in this dissertation is a multi-scalar, integrative analysis of the molecular and neuroanatomic substrates that underlie emotion-related behavior. The amygdala is a principle component of the …

Pax5 Haploinsufficiency Cooperates With Bcr-Abl1 To Induce Acute Lymphoblastic Leukemia, Christopher B. Miller

Theses and Dissertations (ETD)

Acute lymphoblastic leukemia (ALL) is the commonest pediatric malignancy and comprises several distinct subtypes each with its own unique pathogenesis, clinical behavior, and response to therapy. Chromosomal aberrations are a hallmark of ALL but alone fail to induce leukemia. Pediatric ALLs can be divided into several categories based on the expression of several genetically conserved chromosomal translocations including the t(9,22)[BCR-ABL1], t(1,19)[TCF3-PBX1], t(12,21)[ETV6-RUNX1], MLLrearranged leukemia’s, hyperdiploid and hypodiploid karyotypes, and T-lineage leukemia. Each translocation confers a characteristic transforming phenotype within the cell in which it originates but is alone insufficient to induce overt leukemia. …

Insights Into Btb-Cul3 Ubiquitin Ligases From The Structures Of Spop-Substrate Complexes, Min Zhuang

Theses and Dissertations (ETD)

Cullin-Ring ubiquitin ligases (CRLs) are E3 complexes that specifically recognize substrates through substrate adaptors. In the largest CRL subfamily, Cul3 binds a BTB domain, and a protein-interaction domain such as MATH recruits substrates for ubiquitination. Here we present biochemical and structural analyses of the MATH and BTB domain containing protein, SPOP, which regulates diverse signaling pathways. First, we identified a conserved SPOP Binding Consensus (SBC) motif in the transcriptional regulator Ci, the protein phosphatase Puc, and the chromatin component MacroH2A. The SBC motif specifically binds the MATH domain of SPOP, and is required for Puc ubiquitination in vitro and in …

Structural And Kinetics Studies Of The Enzyme Dihydropteroate Synthase And The Implications For Antibiotic Resistance, Katherine A. Ayers

Theses and Dissertations (ETD)

The goal of this study is to develop small molecule inhibitors of DHPS for the treatment of a variety of infectious diseases. According to the World Health Organization (WHO), infectious diseases kill more than 13 million people worldwide every year making it the second leading cause of death behind cardiovascular disease. The sulfonamide class of drugs has been in use since the 1930’s to treat many infectious agents and act by targeting the enzyme dihydropteroate synthase (DHPS) of the prokaryotic and lower eukaryotic folate pathway.

DHPS is an ideal drug target because humans do not synthesize folate de novo and …

Regulation Of Pyruvate Dehydrogenase Kinase 4 By Thyroid Hormone / Role Of Peroxisome Proliferator Activated Receptor Gamma Coactivator-1 Alpha And Ccaat Enhancer Binding Protein, Ramy Naguib Attia

Theses and Dissertations (ETD)

Pyruvate dehydrogenase kinase 4 (PDK4) regulates pyruvate oxidation through the phosphorylation and inhibition of the pyruvate dehydrogenase complex (PDC). The PDC catalyzes the conversion of pyruvate to acetyl-CoA and it is an important control point in glucose and pyruvate metabolism. Previous studies had reported that PDK4 gene expression is induced by thyroid hormone (T3). These studies did not investigate the mechanisms by which T3 regulated PDK4 gene expression. I have examined the role of the thyroid hormone receptor (TR), transcriptional coactivators especially the peroxisome proliferator activated receptor gamma coactivator-1 (PGC-1α) and other transcription factors that act as accessory factors in …

Spatial Resolution Analysis Of A Variable Resolution X-Ray Cone-Beam Computed Tomography System, Bahram Dahi

Theses and Dissertations (ETD)

A new cone-beam computed tomography (CBCT) system is designed and implemented that can adaptively provide high resolution CT images for objects of different sizes. The new system, called Variable Resolution X-ray Cone-beam CT (VRX-CBCT) uses a CsI-based amorphous silicon flat panel detector (FPD) that can tilt about its horizontal (u) axis and vertical (v) axis independently. The detector angulation improves the spatial resolution of the CT images by changing the effective size of each detector cell. Two components of spatial resolution of the system, namely the transverse and axial modulation transfer functions (MTF), are analyzed in …

Obesity, Adiposity, And Satiety In Mouse Models Of Smith-Magenis Syndrome And Dup(17)(P11.2) Syndrome, Brooke Burns

Theses and Dissertations

Smith-Magenis syndrome (SMS) is a complex disorder caused by haploinsufficiency of RAI1 and characterized by sleep disturbances, behavioral abnormalities, mental retardation, and obesity in teens and adults. Rai1+/- mice are obese after 20 weeks. Dup(17)(p11.2) syndrome is a complex disorder associated with overexpression of RAI1. A transgenic mouse model of dup(17)(p11.2) syndrome overexpresses Rai1 and results in a mouse that is growth delayed. In order to characterize the obese phenotypes of mouse models of SMS and the role of RAI1 in obesity, daily food intake and serum levels of insulin, glucose, PPY, and leptin were measured; adiposity was studied by …

Upregulation Of Pip3-Dependent Rac Exchanger 1 (P-Rex1) Promotes Prostate Cancer Metastasis., Jianbing Qin, Yan Xie, Bo Wang, Mikio Hoshino, Dennis W. Wolff, Jing Zhao, Margaret A. Scofield, Frank J. Dowd, Ming-Fong Lin, Yaping Tu

Journal Articles: Biochemistry & Molecular Biology

Excessive activation of G-protein-coupled receptor (GPCR) and receptor tyrosine kinase (RTK) pathways has been linked to prostate cancer metastasis. Rac activation by guanine nucleotide exchange factors (GEFs) plays an important role in directional cell migration, a critical step of tumor metastasis cascades. We found that the upregulation of P-Rex1, a Rac-selective GEF synergistically activated by Gbetagamma freed during GPCR signaling, and PIP3, generated during either RTK or GPCR signaling, strongly correlates with metastatic phenotypes in both prostate cancer cell lines and human prostate cancer specimens. Silencing endogenous P-Rex1 in metastatic prostate cancer PC-3 cells selectively inhibited Rac activity and reduced …

U2os Cells Lacking Chk1 Undergo Aberrant Mitosis And Fail To Activate The Spindle Checkpoint, Laura Carrassa, Yolanda Sanchez, Eugenio Erba, Giovanna Damia

Dartmouth Scholarship

Chk1 is a conserved protein kinase originally identified in fission yeast, required to delay entry of cells with damaged or unreplicated DNA into mitosis. The requirement of Chk1 for both S and G2/M checkpoints has been elucidated while only few studies have connected Chk1 to the mitotic spindle checkpoint. We used a small interference RNA strategy to investigate the role of Chk1 in unstressed conditions. Chk1 depletion in U2OS human osteosarcoma cells inhibited cell proliferation and raised the percentage of cells with a 4N DNA content, which correlated with accumulation of giant polynucleated cells morphologically distinct from apoptotic cells, while …

Metallic Nickel Nano- And Fine Particles Induce Jb6 Cell Apoptosis Through A Caspase-8/Aif Mediated Cytochrome C-Independent Pathway, Jinshun Zhao, Linda Bowman, Xingdong Zhang, Xianglin Shi, Binghua Jiang, Vincent Castranova, Min Ding

Toxicology and Cancer Biology Faculty Publications

BACKGROUND: Carcinogenicity of nickel compounds has been well documented. However, the carcinogenic effect of metallic nickel is still unclear. The present study investigates metallic nickel nano- and fine particle-induced apoptosis and the signal pathways involved in this process in JB6 cells. The data obtained from this study will be of benefit for elucidating the pathological and carcinogenic potential of metallic nickel particles.

RESULTS: Using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, we found that metallic nickel nanoparticles exhibited higher cytotoxicity than fine particles. Both metallic nickel nano- and fine particles induced JB6 cell apoptosis. Metallic nickel nanoparticles produced higher apoptotic induction than fine …

Therapeutic Drugs In Cancer, Teneille Walker

Theses and Dissertations

The first study examined the interaction between low doses of the multi-kinase inhibitor sorafenib and the histone deacetylase inhibitor vorinostat in colon cancer cells. Sorafenib and vorinostat synergized to kill HCT116 and SW480 cells. In SW480 cells, sorafenib+vorinostat toxicity correlated with CD95 activation and CD95-stimulated autophagy. Drug lethality in SW480 cells was blocked by knock down of CD95. In SW620 cells that are patient matched to SW480 cells, sorafenib+vorinostat toxicity was significantly reduced that correlated with a lack of CD95 activation and lower expression of ceramide synthase 6 (LASS6). Overexpression of LASS6 in SW620 cells enhanced drug-induced CD95 activation and …

Immunomodulatory Effects Of Novel Therapies For Stroke, Aaron A. Hall

USF Tampa Graduate Theses and Dissertations

Each year, approximately 795,000 people suffer a new or recurrent stroke. About 610,000 of these are first attacks, and 185,000 are recurrent attacks (Carandang et al. 2006). Currently the only FDA approved treatment for ischemic stroke is recombinant tissue plasminogen activator (Alteplase) (Marler and Goldstein 2003). Unfortunately its use is restricted to a short, 4.5 hour, time window. Two promising therapies in the treatment of stroke at delayed timepoints are human umbilical cord blood cells (HUCBC) and the sigma receptor agonist DTG

The first series of experiments were conducted to characterize the effects of sigma receptors on various aspects of …

Lineage-Specific T-Cell Responses To Cancer Mucosa Antigen Oppose Systemic Metastases Without Mucosal Inflammatory Disease., Adam E. Snook, Peng Li, Benjamin J Stafford, Elizabeth J Faul, Lan Huang, Ruth C Birbe, Alessandro Bombonati, Stephanie Schulz, Matthias J. Schnell, Laurence C. Eisenlohr, Scott A. Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Cancer mucosa antigens are emerging as a new category of self-antigens expressed normally in immunologically privileged mucosal compartments and universally by their derivative tumors. These antigens leverage the established immunologic partitioning of systemic and mucosal compartments, limiting tolerance opposing systemic antitumor efficacy. An unresolved issue surrounding self-antigens as immunotherapeutic targets is autoimmunity following systemic immunization. In the context of cancer mucosa antigens, immune effectors to self-antigens risk amplifying mucosal inflammatory disease promoting carcinogenesis. Here, we examined the relationship between immunotherapy for systemic colon cancer metastases targeting the intestinal cancer mucosa antigen guanylyl cyclase C (GCC) and its effect on inflammatory …

Evaluating Statistical Methods Used To Estimate The Number Of Postsynaptic Receptors, Georgios Kalantzis, Yoshira Kubota, Harel Z Shouval

Faculty, Staff and Student Publications

Calcium levels in spines play a significant role in determining the sign and magnitude of synaptic plasticity. The magnitude of calcium influx into spines is highly dependent on influx through N-methyl D-aspartate (NMDA) receptors, and therefore depends on the number of postsynaptic NMDA receptors in each spine. We have calculated previously how the number of postsynaptic NMDA receptors determines the mean and variance of calcium transients in the postsynaptic density, and how this alters the shape of plasticity curves. However, the number of postsynaptic NMDA receptors in the postsynaptic density is not well known. Anatomical methods for estimating the number …

Characterization Of Conserved Properties Of Hemagglutinin Of H5n1 And Human Influenza Viruses: Possible Consequences For Therapy And Infection Control, Veljko Veljkovic, Nevena Veljkovic, Claude P. Muller, Sybille Müller, Sanja Glisic, Vladimir Perovic, Heinz Köhler

Microbiology, Immunology, and Molecular Genetics Faculty Publications

BACKGROUND: Epidemics caused by highly pathogenic avian influenza virus (HPAIV) are a continuing threat to human health and to the world's economy. The development of approaches, which help to understand the significance of structural changes resulting from the alarming mutational propensity for human-to-human transmission of HPAIV, is of particularly interest. Here we compare informational and structural properties of the hemagglutinin (HA) of H5N1 virus and human influenza virus subtypes, which are important for the receptor/virus interaction.

RESULTS: Presented results revealed that HA proteins encode highly conserved information that differ between influenza virus subtypes H5N1, H1N1, H3N2, H7N7 and defined an …

The Proteolytic Stability And Cytotoxicity Studies Of L‐Aspartic Acid And L‐Diaminopropionic Acid Derived Β‐Peptides And A Mixed Α/Β‐Peptide, Sahar Ahmed, Kamaljit Kaur

Pharmacy Faculty Articles and Research

The use of peptides as drugs in pharmaceutical applications is hindered by their susceptibility to proteolysis and therefore low bioavailability. β‐Peptides that contain an additional methylene group in the backbone, are gaining recognition from a pharmaceutical stand point as they are considerably more resilient to proteolysis and metabolism. Recently, we reported two new classes of β‐peptides, β³‐ and β²‐peptides derived from l‐aspartic acid and l‐diaminopropionic acid, respectively. Here, we report the proteolytic stability of these β‐peptidic compounds and a mixed α /β‐peptide against three enzymes (pronase, trypsin and elastase), as well as, human serum. The …

Therapeutic Drugs In Cancer And Resistance., Aditi Pandya Martin

Theses and Dissertations

We investigated the mechanism of toxicity and resistance development of small molecule tyrosine kinase inhibitor lapatinib in HCT 116 colon cancer cells. Lapatinib mediated cell death in HCT 116 cells was caspase independent and involved cytosolic release of apoptosis inducing factor. Treatment of HCT 116 cells with 10µM Lapatinib lead to the outgrowth of lapatinib resistant HCT 116 cells. Our studies show that alterations in the expression and activation of Bcl-2 family proteins allow lapatinib resistant HCT 116 cells to resist cytotoxic effects of lapatinib as well as of other commonly used chemotherapeutic agents. In hepatoma and pancreatic cancer cells, …

Lean And Obese Zucker Rats Exhibit Different Patterns Of P70s6 Kinase Regulation In The Tibialis Anterior Muscle In Response To High-Force Muscle Contraction, Anjaiah Katta, Sunil K. Karkala, Miaozong Wu, Sarath Meduru, Devashish H. Desai, Kevin M. Rice, Eric R. Blough

MIIR Faculty Research

Increased phosphorylation of the 70-kDa ribosomal S6 kinase (p70S6k) signaling is strongly correlated with the degree of muscle adaptation following exercise. Herein we compare the phosphorylation of p70S6k, Akt, and mammalian target of rapamycin (mTOR) in the tibialis anterior (TA) muscles of lean and obese Zucker rats following a bout of eccentric exercise. Exercise increased p70S6k (Thr389) phosphorylation immediately after (33.3 ± 7.2%) and during [1 h (24.0 ± 14.9%) and 3 h (24.6 ± 11.3%)] recovery in the lean TA and at 3 h (33.5 ± 8.0%) in the obese TA Zucker rats. mTOR (Ser2448) phosphorylation was elevated in …

A Study Of Micrornas In Silico And In Vivo: Diagnostic And Therapeutic Applications In Cancer., Scott A Waldman, Andre Terzic

Department of Pharmacology and Experimental Therapeutics Faculty Papers

There is emerging evidence of the production in human tumors of abnormal levels of microRNAs (miRNAs), which have been assigned oncogenic and/or tumor-suppressor functions. While some miRNAs commonly exhibit altered amounts across tumors, more often, different tumor types produce unique patterns of miRNAs, related to their tissue of origin. The role of miRNAs in tumorigenesis underscores their value as mechanism-based therapeutic targets in cancer. Similarly, unique patterns of altered levels of miRNA production provide fingerprints that may serve as molecular biomarkers for tumor diagnosis, classification, prognosis of disease-specific outcomes and prediction of therapeutic responses.

Defining Family: Naming, Orientation, And Redemption In The Case Of Terri Schiavo, M. Chad Mcbride, Karen L. Taas, Paige W. Toller

Communication Faculty Publications

This paper undertakes a detailed analysis of the Terri Schiavo case as it was covered in popular media. Drawing on Burkean theory, we argue a critical issue in the case was a struggle between Terri's parents and husband to be seen as the more legitimate family in order to determine the duration and extent of Terri 's medical care. We discuss how the private debate over Terri's health and the decision to remove her feeding tube entered into the public scenes of legal and political action. This shift to the public scene represented problems for the parties directly involved in …

Long-Distance Delivery Of Bacterial Virulence Factors By Pseudomonas Aeruginosa Outer Membrane Vesicles, Jennifer M. Bomberger, Daniel P. Maceachran, Bonita A. Coutermarsh, Siying Ye, George A. O'Toole, Bruce A. Stanton, Frederick M. Ausubel

Dartmouth Scholarship

Bacteria use a variety of secreted virulence factors to manipulate host cells, thereby causing significant morbidity and mortality. We report a mechanism for the long-distance delivery of multiple bacterial virulence factors, simultaneously and directly into the host cell cytoplasm, thus obviating the need for direct interaction of the pathogen with the host cell to cause cytotoxicity. We show that outer membrane–derived vesicles (OMV) secreted by the opportunistic human pathogen Pseudomonas aeruginosa deliver multiple virulence factors, including β-lactamase, alkaline phosphatase, hemolytic phospholipase C, and Cif, directly into the host cytoplasm via fusion of OMV with lipid rafts in the host plasma …

Regulation Of The Mazef Toxin-Antitoxin Module In Staphylococcus Aureus And Its Impact On Sigb Expression, Niles P. Donegan, Ambrose L. Cheung

Dartmouth Scholarship

In Staphylococcus aureus, the sigB operon codes for the alternative sigma factor σ^Band its regulators that enable the bacteria to rapidly respond to environmental stresses via redirection of transcriptional priorities. However, a full model of σ^Bregulation in S. aureus has not yet emerged. Earlier data has suggested that mazEF, a toxin-antitoxin (TA) module immediately upstream of the sigB operon, was transcribed with the sigB operon. Here we demonstrate that the promoter P_mazE upstream of mazEF is essential for full σ^B activity and that instead of utilizing autorepression typical of TA systems, sigB …

Borrelia Burgdorferi Ebfc Defines A Newly-Identified, Widespread Family Of Bacterial Dna-Binding Proteins, Sean P. Riley, Tomasz Bykowski, Anne E. Cooley, Logan H. Burns, Kelly Babb, Catherine A. Brissette, Amy Bowman, Matthew L. Rotondi, M. Clarke Miller, Edward Demoll, Kap Lim, Michael G. Fried, Brian Stevenson

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The Lyme disease spirochete, Borrelia burgdorferi, encodes a novel type of DNA-binding protein named EbfC. Orthologs of EbfC are encoded by a wide range of bacterial species, so characterization of the borrelial protein has implications that span the eubacterial kingdom. The present work defines the DNA sequence required for high-affinity binding by EbfC to be the 4 bp broken palindrome GTnAC, where ‘n’ can be any nucleotide. Two high-affinity EbfC-binding sites are located immediately 5′ of B. burgdorferi erp transcriptional promoters, and binding of EbfC was found to alter the conformation of erp promoter DNA. Consensus EbfC-binding …

INTRODUCTION: Actual 5-year survival rates of 10-18% have been reported for patients with resected pancreatic adenocarcinoma (PC), but the use of multimodality therapy was uncommon in these series. We evaluated long-term survival and patterns of recurrence in patients treated for PC with contemporary staging and multimodality therapy.

METHODS: We analyzed 329 consecutive patients with PC evaluated between 1990 and 2002 who underwent resection. Each received a multidisciplinary evaluation and a standard operative approach. Pre- or postoperative chemotherapy and/or chemoradiation were routine. Surgical specimens of 5-year survivors were re-reviewed. A multivariate model of factors associated with long-term survival was constructed.

When Old-Order Amish Meet New Order Science: Genetic Maladies And The Amish Dilemma, Kelley Downey

Undergraduate Research Conference

The Old World Amish, an Anabaptist Christian domination in the United States and Canada are know for their plain dress, avoidance of modern technology, and separation from the mainstream society.

A traditional agricultural religious group, the Old World Amish maintains isolation from the rest of the community. Financially well-off, they are homogeneous on education, occupation by gender, age at marriage, religion/ethnicity, and health care.

Although the Amish strongly discourage marriage between close cousins, the Lancaster Amish genealogy is described as mutational - inbreeding from multiple, remote connections rather than close consanguinity (first-cousin marriages).

Amish settlements have been identified with certain …
