Amelioration Of Prenatal Alcohol Effects By Environmental Enrichment In A Mouse Model Of Fasd, Aniruddho Chokroborty-Hoque 2017 The University of Western Ontario

Amelioration Of Prenatal Alcohol Effects By Environmental Enrichment In A Mouse Model Of Fasd, Aniruddho Chokroborty-Hoque

Electronic Thesis and Dissertation Repository

Maternal alcohol consumption during pregnancy results in a spectrum of behavioural and cognitive deficits collectively known as Fetal Alcohol Spectrum Disorders (FASD). Currently, little is know about if and how the external environment may modulate these deficits. I have used C57BL/6 mice to study this interaction between prenatal alcohol exposure and the postnatal environment. Alcohol exposure during synaptogenesis produces high levels of anxiety-like traits and decreased memory performance. Alcohol-exposed mice (and matched unexposed controls) were put in 'environmentally-enriched' conditions of voluntary exercise, physical activities and cognitive stimulation to ascertain the effects of a positive postnatal environment. The results show ...

Germ-Line Gene Editing And Congressional Reaction In Context: Learning From Almost 50 Years Of Congressional Reactions To Biomedical Breakthroughs, Russell A. Spivak, J.D., I. Glenn Cohen, J.D., Eli Y. Adashi, M.D., M.S.

Journal of Law and Health

On December 18, 2015, President Obama signed into law a policy rider forestalling the therapeutic modification of the human germ line. The rider, motivated by the science’s potential unethical ends, is only the most recent instance in which the legislature cut short the ongoing national conversation on the acceptability of a developing science. This essay offers historical perspective on what bills were proposed and passed surrounding four other then-developing scientific breakthroughs—Recombinant DNA, in vitro fertilization, Cloning, Stem Cells—to better analyze how Congress is, and should, regulate this exciting and promising science.


Investigating The Role Of Dispatched In Hedgehog Ligand Transport And Delivery, William Bodeen 2017 University of Tennessee Health Science Center

Investigating The Role Of Dispatched In Hedgehog Ligand Transport And Delivery, William Bodeen

Theses and Dissertations (ETD)

During the development of all metazoans, the Hedgehog (Hh) signaling pathway provides instructional cues influencing a variety of cellular processes. The pathway ligand, Hh, is dually lipidated by cholesterol and palmitate, which effectively anchors the molecule to the lipid bilayer of the signal producing cell. To complicate the Hh pathway induction process, the Hh ligand is often produced at a significant distance from the cells it influences. Only one known conserved molecule, Dispatched (Disp), can alleviate the membrane tethering imparted by Hh lipidation. Underscoring the importance of Disp protein during development, knockout animals succumb to lethality at E9.5, an ...

Measuring pH is one of the most commonly used techniques in both the laboratory as well as the field due to its importance in a multitude of biochemical processes. Traditional methods of measuring pH may be highly developed in accuracy and precision but often involve disruption of the environment. Biological markers offer an alternative that allows for long-term pH monitoring. This innovative approach allows for vast applications such as in the manufacturing, food processing and research industries. Under moderate acidic conditions, the asr (acid shock RNA) gene is highly inducible and has been demonstrated to be crucial for growth at ...


Sleep Disturbances And Depression: The Role Of Genes And Trauma, Mackenzie J. Lind 2017 Virginia Commonwealth University

Sleep Disturbances And Depression: The Role Of Genes And Trauma, Mackenzie J. Lind

Theses and Dissertations

Sleep disturbances and insomnia are prevalent, with around 33% of adults indicating that they experience at least one main symptom of insomnia, and bidirectional relationships exist with common psychopathology, particularly major depressive disorder (MDD). However, genetic and environmental (e.g., traumatic event exposure) contributions to the etiology of these phenotypes are not yet well understood. A genetically informative sample of approximately 12,000 Han Chinese women aged 30-60 (50% with recurrent MDD) was used to address several gaps within the sleep literature. Sleep disturbances were assessed in all individuals using a general item addressing sleeplessness (GS). A sleep within depression ...


Assessment Of Patient Satisfaction With The Provision Of Fertility Information In Women With Lynch Syndrome, Rachel Elizabeth Hickey 2017 University of South Carolina

Assessment Of Patient Satisfaction With The Provision Of Fertility Information In Women With Lynch Syndrome, Rachel Elizabeth Hickey

Theses and Dissertations

Lynch Syndrome (LS), one of the most common hereditary cancer syndromes, is primarily known for its substantially increased risks for colorectal cancer. The incidence of gynecologic cancers (endometrial and ovarian cancers) equals or exceeds the incidence of colorectal cancers in female patients with LS. The prevention and treatment methods for these cancers can drastically affect fertility and reproduction. Previous studies with cancer patients have revealed challenges in acquiring information related to these topics; thus far, no research has assessed whether there is an informational gap regarding fertility information for women in the LS population. The purpose of this study was ...


Adoptees’ Experiences With Direct-To-Consumer Genetic Testing: Emotions, Satisfaction, And Motivating Factors, Anna Childers 2017 University of South Carolina

Adoptees’ Experiences With Direct-To-Consumer Genetic Testing: Emotions, Satisfaction, And Motivating Factors, Anna Childers

Theses and Dissertations

Public awareness of the role of genetics in disease continues to expand along with the use of direct-to-consumer genetic testing (DTC-GT). One subset of customers taking advantage of the growing DTC-GT market is adoptees. Prior research has shown that adoptees appear to be more motivated than non-adoptees to learn about their genetic disease risk but have similar responses to health-related information acquired through DTC-GT. In this exploratory qualitative study, fourteen adoptees were asked about their motivations for pursuing DTC-GT; satisfaction with results; emotions throughout the process; and interest in meeting with a genetic counselor. Motivations for pursuing DTCGT fell into ...

Integrative Genomic And Transcriptomic Analysis For Pinpointing Recurrent Alterations Of Plant Homeodomain Genes And Their Clinical Significance In Breast Cancer, Huimei Yu, Yuanyuan Jiang, Lanxin Liu, Wenqi Shan, Xiaofang Chu, Zhe Yang, Zeng-Quan Yang

Oncology Faculty Publications

A wide range of the epigenetic effectors that regulate chromatin modification, gene expression, genomic stability, and DNA repair contain structurally conserved domains called plant homeodomain (PHD) fingers. Alternations of several PHD finger-containing proteins (PHFs) due to genomic amplification, mutations, deletions, and translocations have been linked directly to various types of cancer. However, little is known about the genomic landscape and the clinical significance of PHFs in breast cancer. Hence, we performed a large-scale genomic and transcriptomic analysis of 98 PHF genes in breast cancer using TCGA and METABRIC datasets and correlated the recurrent alterations with clinicopathological features and survival of ...

Gene-by-environment (GxE) interactions determine common disease risk factors and biomedically relevant complex traits. However, quantifying how the environment modulates genetic effects on human quantitative phenotypes presents unique challenges. Environmental covariates are complex and difficult to measure and control at the organismal level, as found in GWAS and epidemiological studies. An alternative approach focuses on the cellular environment using in vitro treatments as a proxy for the organismal environment. These cellular environments simplify the organism-level environmental exposures to provide a tractable influence on subcellular phenotypes, such as gene expression. Expression quantitative trait loci (eQTL) mapping studies identified GxE interactions in response ...

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a common genetic disease that leads to progressive renal cyst growth and loss of renal function, and is caused by mutations in the genes encoding polycystin-1 (PC1) and polycystin-2 (PC2), respectively. The PC1/PC2 complex localizes to primary cilia and can act as a flow-dependent calcium channel in addition to numerous other signaling functions. The exact functions of the polycystins, their regulation and the purpose of the PC1/PC2 channel are still poorly understood. PC1 is an integral membrane protein with a large extracytoplasmic N-terminal domain and a short, ~200 amino acid C-terminal ...

Analyzing Mutations Of Spt7 Protein That Disrupt Interaction With Sf3b Subunits, Arryn T. Harris, Peyton J. Spreacker, Rachel Stegeman, Vikki M. Weake, Edwin C. Acosta

The Summer Undergraduate Research Fellowship (SURF) Symposium

Proper transcription, the process of converting DNA to RNA, is crucial for the health and viability of an organism. This process is regulated by many proteins, such as co-transcriptional activators; one being the protein complex known as Spt-Ada-Gcn5-acetyltransferase, or SAGA. While much is known about the roles of SAGA in cell processes, how SAGA’s subunits promote functionality is still unknown. The focus of this study is to analyze the purpose of SAGA’s SF3B subunits. These subunits are also found in the spliceosome, the compound responsible for generating mature RNA. SAGA has no known functions relating to this process ...

A Walk On The Fine Line Between Reward And Risk: Aav-Ifnβ Gene Therapy For Glioblastoma: A Dissertation, Dwijit Guhasarkar

GSBS Dissertations and Theses

Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor. The current standard-of-care treatment including surgery, radiation and temozolomide (TMZ) chemotherapy does not prolong the survival satisfactorily. Here we have tested the feasibility, efficacy and safety of a potential gene therapy approach using AAV as gene delivery vehicle for treatment of GBM.

Interferon-beta (IFNβ) is a cytokine molecule also having pleiotropic anticancerous properties. Previously it has been shown by our group that AAV mediated local (intracranial) gene delivery of human IFNβ (hIFNβ) could be an effective treatment for non-invasive human glioblastoma (U87) in orthotopic xenograft mouse model.But ...


Activation Of Target Gene Expression In Neurons By The C. Elegans Rfx Transcription Factor, Daf-19, Katherine P. Mueller 2016 Lawrence University

Activation Of Target Gene Expression In Neurons By The C. Elegans Rfx Transcription Factor, Daf-19, Katherine P. Mueller

Lawrence University Honors Projects

DAF-19, the only RFX transcription factor found in C. elegans, is required for the formation of neuronal sensory cilia. Four isoforms of the DAF-19 protein have been reported, and the m86 nonsense (null) mutation affecting all four isoforms has been shown to prevent cilia formation. Transcriptome analyses employing microarrays of L1 and adult stage worms were completed using RNA from daf-19(m86) worms and an isogenic wild type strain to identify additional putative DAF-19 target genes. Using transcriptional fusions with GFP, we compared the expression patterns of several potential gene targets using fluorescence confocal microscopy. Expression patterns were characterized in ...

Alpha-1 antitrypsin (AAT) deficiency is a common monogenic disorder resulting in emphysema, which is currently treated with weekly infusions of protein replacement. We previously reported achieving plasma wild-type (M) AAT concentrations at 2.5-3.8% of the therapeutic level at 1 year after intramuscular (IM) administration of 6×1012vg/kg of a recombinant adeno-associated virus serotype 1 (rAAV1)-AAT vector in AAT-deficient patients, with an associated regulatory T cell (Treg) response to AAV1 capsid epitopes in the absence of any exogenous immune suppression. Here, we report sustained expression at greater than 2% of the therapeutic level for 5 years after ...


Novel Oncogenic Drivers In Pediatric Gliomagenesis, Alexander K. Diaz 2016 University of Tennessee Health Science Center

Novel Oncogenic Drivers In Pediatric Gliomagenesis, Alexander K. Diaz

Theses and Dissertations (ETD)

Pediatric high-grade gliomas (pHGGs), with a two-year survival rate of less than 20%, are some of the most aggressive human cancers. This dissertation begins with our analysis of 127 pHGGs, including brainstem (BS) and non-brainstem (NBS) tumors, from 118 patients using next-generation sequencing technologies. Nearly one-third of BS-HGGs, also known as diffuse intrinsic pontine gliomas (DIPGs), harbored somatic heterozygous missense mutations in ACVR1, coding for a receptor serine-threonine kinase involved in bone morphogenetic protein (BMP) signaling. These alterations led to gain-of-function as evidenced by increased phosphorylation of downstream targets in primary astrocytes and zebrafish embryo ventralization. Whole-genome sequencing and RNASeq ...

MicroRNA (miRNA) expression has rapidly grown into one of the largest fields for disease characterization and development of clinical biomarkers. Consensus is lacking in regards to the optimal sample source or if different circulating sources are concordant. Here, using miRNA measurements from contemporaneously obtained whole blood- and plasma-derived RNA from 2391 individuals, we demonstrate that plasma and blood miRNA levels are divergent and may reflect different biological processes and disease associations.

Molecular mediators of metabolic processes, to increase energy expenditure, have become a focus for therapies of obesity. The discovery of cytokines secreted from the skeletal muscle (SKM), termed “myokines,” has garnered attention due to their positive effects on metabolic processes. Interleukin-15 (IL-15) is a myokine that has numerous positive metabolic effects and is linked to the PPAR family of mitochondrial regulators. Here, we aimed to determine the importance of PPAR𝛼 and/or PPAR𝛿 as targets of IL-15 signaling. C2C12 SKM cells were differentiated for 6 days and treated every other day with IL-15 (100 ng/mL), a PPAR𝛼 inhibitor (GW-6471 ...
