Circadian Clock Development and Initiation in Drosophila melanogaster
(2017-07-31)In Drosophila, time-keeping is based on a ~24h transcription feedback loop, in which CLOCK-CYCLE (CLK-CYC) heterodimers activate transcription of genes encoding the feedback repressors PERIOD (PER) and TIMELESS (TIM). ... -
Control of rhythmic output from the circadian clock in Neurospora crassa
(Texas A&M University, 2005-02-17)Circadian rhythms are visible as daily oscillations in biochemical, physiological, or behavioral processes. These rhythms are produced by an endogenous clock that maintains synchrony with the external environment through ... -
Copy Number and Gene Expression: Stochastic Modeling and Therapeutic Application
(2013-05-01)The advances of high-throughput technologies, such as next-generation sequencing and microarrays, have rapidly improved the accessibility of molecular profiles in tumor samples. However, due to the immaturity of relevant ... -
Detecting Aflatoxicosis in Broilers in the Evaluation of Clay-based, Toxin-binding Feed Additives
(2014-11-17)The objectives of this research were to evaluate common biological measures of aflatoxicosis in broilers (such as growth rate and relative organ weights) along with variables such as hepatic gene expression and aflatoxin ... -
Effect of Mesenchymal Stem Cells on Equine Ovarian Follicular Development and Gene Expression
(2017-06-09)Aging affects the reproductive efficiency of females. In rodent models, injection of mesenchymal stem cells (MSCs) improves function and induces trophic mRNA expression in ovaries compromised by chemotherapy. However, ... -
Effects of Fatty Acids on Gene Expression and Lipid Metabolism in Bovine Intramuscular and Subcutaneous Adipose Tissues
(2012-10-19)Pasture feeding depresses adipose tissue development in beef cattle whereas grain feeding, enhances adipogenesis. Therefore, we hypothesized that specific fatty acids would differentially affect lipogenesis in explants ... -
Effects of Genetic Variants on Gene Expression Variability
(2016-05-09)Variation and variability of gene expression are central concepts in biology. Variation refers to differences among individuals, whereas variability refers to the potential of a population to vary. The advent of next-generation ... -
Elucidating the Functions of the Sialylation Pathway in Drosophila melanogaster
(2012-10-19)Sialylation is an important carbohydrate modification of glycoconjugates, which introduces sialic acids (SA). The relatively large nine-carbon, negatively charged sugars are typically located at the termini of carbohydrate ... -
Environmental Influences on Virulence Factors in Vibrio Vulnificus
(2016-01-07)Understanding the environmental factors influencing virulence of V. vulnificus is of utmost importance in reducing human exposure to this deadly pathogen. Quantitative PCR assays for the virulence indicator genes vcg and ... -
Establishing novel relationships between genetic variants and gene expression in humans
(2013-02-27)We observe phenotypic variations in the human population every day; however, the underlying genetic mechanism behind these variations is difficult to decipher. In this project I investigate the links between phenotypic and ... -
Evaluation of alterations in gene expression in MCF-7 cells induced by the agricultural chemicals Enable and Diazinon
(Texas A&M University, 2005-08-29)Steroid hormones, such as estrogen, are produced in one tissue and carried through the blood stream to target tissues in which they bind to highly specific nuclear receptors and trigger changes in gene expression and ... -
Expression Analysis of BB0174, A Membrane Protein of Borrelia burgdorferi, the Causative Agent of Lyme Disease
(2012-04-30)Borrelia burgdorferi (Bb), the causative agent of Lyme disease, is a spirochetal pathogen that colonizes mammalian hosts causing numerous neurological and physiological symptoms. This thesis focuses on the gene expression ... -
Functional and Genomic Drivers of Wooden Breast in Commercial Broilers
(2019-07-08)Commercial meat-chickens (broilers) have been heavily selected for performance traits including high body weights, large breast muscle size, and improved feed efficiency. The wooden breast condition (WB) is a consequence ... -
Functions of Arabidopsis C-terminal Domain Phosphatase-like 4 in Global Transcriptional Regulation
(2017-05-02)Phosphoregulation of the carboxyl-terminal domain of RNA polymerase II largest subunit (pol II-CTD) couples transcription and co-transcriptional modification of nascent RNA. Although the molecular mechanisms have been ... -
Gene Expression and Association Analyses of Stress Responses in Loblolly Pine (Pinus taeda L.)
(2012-02-14)The molecular mechanisms underlying disease-resistance and drought-resistance in forest trees are not well understood. Linking variation in gene expression with genetic polymorphisms and with variations in disease- and ... -
