Identification Of The Transactivation Domain Of The Transcription Factor Sox-2 And An Associated Co-Activator, Tamara K. Nowling, Lance R. Johnson, Matthew S. Wiebe, Angie Rizzino

Nebraska Center for Virology: Faculty Publications

The importance of interactions between Sox and POU transcription factors in the regulation of gene expression is becoming increasingly apparent. Recently, many examples of the involvement of Sox-POU partnerships in transcription have been discovered, including a partnership between Sox-2 and Oct-3. Little is known about the mechanisms by which these factors modulate transcription. To better understand the molecular interactions involved, we mapped the location of the transactivation do-main of Sox-2. This was done in the context of its interaction with Oct-3, as well as its ability to transactivate as a fusion protein linked to the DNA-binding domain of Gal4. Both …

Comparison Of Plasma Fsh Concentration In Boars And Gilts From Lines Selected For Ovulation Rate And Embryonal Survival, And Litter Size And Estimation Of (Co)Variance Components For Fsh And Ovulation Rate, J. D. Cassady, Rodger K. Dennison, J. J. Ford

Department of Animal Science: Faculty Publications

The objective of this research was to determine whether plasma concentration of FSH was genetically correlated with ovulation rate and thus was a useful trait for indirect selection. Blood samples were collected from 619 animals from five lines of pigs. Line I was selected for increased index of ovulation rate and embryonal survival, and Line C was its randomly selected control. Pigs sampled from Lines I and C were from generations 12 and 13. Pigs from three additional lines that were derived from eighth-generation pigs of Lines I and C also were used. These lines were Line C2, a randomly …

Whole Genome Sequencing Of L.Monocytogenes And L.Innocua : A Basis For Comparative Genomics Of The Genus Listeria, Rachel Purcell

Theses

Listeria monocytogenes is a gram-positive, food-borne human and animal pathogen. L.innocua is a non-pathogenic species the most closely related to L. monocytogenes. Comparative genomics between a pathogenic and a closely related non-pathogenic species is a powerful approach for identifying genes or regions on the chromosome, which might be involved in virulence. Therefore whole genome sequencing of these two organisms was undertaken. The strategy used was based on a random approach combined with end-sequencing of a medium insert library for the finishing phase. Based on the available sequence data for these two species an in silico analysis for the presence of …

Construction Of Escherichia Coli Arginine Repressor Fusion Protein And Analysis Of Its Function In Xer Site-Specific Recombination, Kholis Abdulrachim

Student Works (2000-2009)

In addition to its role in L-arginine biosynthesis in Escherichia coli, arginine repressor (ArgR), the product of the argR gene, also plays an essential role as an obligate accessory protein in Xer site-specific recombination system. A structure-function relationship study of ArgR was performed to understand more about its role in Xcr site-specific recombination. Fusion proteins between ArgRWT (wild-type ArgR) and a biotinylated peptide as well as between ArgRNV (a mutant ArgR) and a biotinylated peptide were constructed. The biotinylated peptide was fused in frame to the amino-tenninus of ArgR WT and ArgRNV, respectively. Xer recombination assays showed that the ArgRWT-biotinylated …

Transcriptional Regulation Of Chicken Apolipoprotein A-I Gene Expression, Wen Lin Kumfert

Theses and Dissertations in Biomedical Sciences

Deregulation of a set of critical cellular genes has long been speculated as a cause of the oncogenic transformation induced by v-Jun oncoprotein. In the past several years, extensive efforts have been made to identify such genes. Several target genes have been identified that are specifically associated with the v-Jun induced transformation phenotype in chicken embryo fibroblasts (CEF).

We have undertaken the objective to identify and characterize the genes that become deregulated in response to, or as a consequence of, Jun-induced transformation. By exploiting the difference in oncogenic potential between v-Jun and c-Jun in CEF, the chicken apolipoprotein A-I (apoA-I) …

Expression And Function Of Hoxc5 And Hoxc6 In The Murine Mammary Gland, Silvia Alejandra Garcia-Gasca

MUSC Theses and Dissertations

Homeotic genes encode transcription factors, believed to regulate cell proliferation, differentiation, as well as cell migration to create positional identities during embryogenesis. In the mouse, the Hox complex consists of at least 39 genes, organized into four clusters, in four different chromosomes. Hoxc5 and Hoxc6 are adjacent genes located in chromosome 15, and are expressed in the developing somites of the thoracic region and central nervous system with overlapping patterns. Both Hoxc5 and Hoxc6 are also expressed in the mammary gland. This study demonstrates that a targeted disruption of the Hoxc6 gene results in a failure of ductal development in …

Scientific Investigation Of The Plant Pathogen Agrobacterium Tumefaciens, Casey M. Flanagan, Christopher B. Crowell Ii, Bryan P. Markelz

Honors Theses

A. tumefaciensis a plant pathogen and causative agent of Crown Gall Disease, an ailment that results in the development of tumors in plants. It is a unique organism in that it is the only known non-viral pathogen that transfers its DNA into the host cell. Consequently, the majority of the research conducted on A. tumefaciensinvestigates its mechanism of infection. However, A. tumefaciensis also rare to the bacterial world in that its genome is comprised of two chromosomes: one circular and one linear. Most other bacteria only have one circular chromosome. This area of research has been grossly overlooked and therefore …

Haemochromatosis Mutation Analysis In A Normal Irish Population, Fergus Ryan, Joseph Vaughan

Articles

187 Irish blood donors were examined for the presence of C282Y and H63D missense mutations using a multiplex PCR and restriction digest protocol. The allele frequency for C282Y was found to be 12.3% which is higher than reported in other studies and concurs that this mutation is of Celtic origin.

Analysis Of The Population Genetics Of The Han And Hui Of Liaoning Province, Peoples Republic Of China, Michael L. Black

Theses: Doctorates and Masters

Throughout recorded Chinese history, regions of the country populated by persons of non-Han ancestry often fluctuated significantly in population numbers and in their political and commercial influence. However, at all times they were considered as important contributors to the nation. Many of these peoples had moved from their homelands, settled in China and had intermarried with Han Chinese. Over the generations they became accepted as fully-fledged Chinese citizens although, in many instances, they retained their traditional customs and religious practices, and frequently their own language. The Hui Muslims are a good example of this process of integration, and today they …

Recent Progress In Psychiatric Genetics—Some Hope But No Hype, Scott F. Stoltenberg, Margit Burmeister

Department of Psychology: Faculty Publications

The reputation of the field of psychiatric genetics has recently become tarnished in the view of many human geneticists. Too many linked loci were claimed and withdrawn, too many association studies published and not confirmed, and, more recently, too many new and different chromosomal regions have been implicated for the same disorder. Here, we summarize recent trends, focusing on research that moves away from traditional linkage studies. Some promising strategies include psychopharmacogenetics and consideration of endophenotypes such as neurophysiological and behavioral markers in addition to the clinical diagnosis. Utilization of rapid and automated methods for scoring genetic variants in large-scale …

Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer

Lawrence G. Harshman Publications

Stress resistance is associated with longevity in Drosophila melanogaster and other model organisms used for genetic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life reproduction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control lines. A relative increase in oxidative stress resistance is a correlated response to selection in this laboratory selection experiment. Increased oxidative stress resistance appears to be a relatively robust correlated response to laboratory selection for late-life reproduction and extended longevity.

Dispersion And Site Fidelity In A Tent-Roosting Population Of The Short-Nosed Fruit Bat (Cynopterus Sphinx) In Southern India, Jay F. Storz, J. Balasingh, P. Thiruchenthil Nathan, K. Emmanuel, Thomas H. Kunz

Jay F. Storz Publications

Patterns of dispersion and site fidelity were investigated in a tent-roosting population of the short-nosed fruit bat, Cynopterus sphinx (Megachiroptera), in southern India. A local population of C. sphinx occupied diurnal roosts in a variable subset of 45 stem tents constructed within the dense foliage of mast trees (Polyalthia longifolia). Individually marked tent-roosting bats were visually censused over the course of a 38-d interval spanning the postpartum oestrus period. On any given day, 33.3-85.7% (mean = 60.8%, SD = 14.2) of adult males roosted singly, with the remainder holding harems of 1-10 breeding females (mean = 3.01, SD …

In Vitro Mutagenesis For Structure/Function Studies Of The Bacteriophage T4 Rega Protein And The Murine Ahr Protein, Estel Rick Barbour

MUSC Theses and Dissertations

The bacteriophage T4 regA protein translationally represses over 30 T4 early genes, including the regA gene, by binding to the translation initiation region of the T4 mRNAs (Karam et al., 1981). Although the recognition sequence has been at least partially characterized in a number regA sensitive mRNAs, there is no consensus sequence or structural feature that is recognized by regA in all transcripts (Winter et al., 1987; Webster et al., 1989; Unnithan et al., 1990). Recent studies have identified an RNA binding site on regA protein, but there remains a large gap in our understanding of how regA protein functions …

Natural Antibodies To Adrenal Hormones And Apolipoprotein E In Cardiovascular Physiology, Shabana Aafaqi

Student Works (2000-2009)

Natural autoantibodies (NAA} are autoantibodies that are present in the sera of healthy individuals. NAA can belong to the lgA, lgG and lgM isotypcs. They exhibit high degrees of polyreactivity and connectivity but low affinity to self antigens. The main function of NAA in healthy people is probably 10 clear the catabolic waste and ageing cells. In this study, an indirect Enzyme-linked lmmunosorbent Assay (ELISA) method was used to detect NAA against hormones, namely adreno-co11ical (hydrocortisone, aldostcrone, androstcncdionc), adrcno-medullary (adrenaline. noradrenaline) and other related steroid hormones (progesterone, testosterone, P-cstradiol). In eleven normal human serum (NHS), lgG anti-cortisol were delcctcd in …
