The Effect Of Db1976 On The Fibrotic Response In Three-Spined Stickleback (Gasterosteus Aculeatus), Saif Quraishi
The Effect Of Db1976 On The Fibrotic Response In Three-Spined Stickleback (Gasterosteus Aculeatus), Saif Quraishi
Honors Scholar Theses
The study of fibrosis in stickleback has been a growing field in which there have been a few studies conducted. This study examines two experiments involving the inhibition of fibrosis in stickleback. The first experiment used fish from the Kenai River Flats (KRF) in Alaska. The second experiment used fish from Roselle Lake in British Columbia, Canada. To determine the impact the drug had on fibrosis, sticklebacks from the KRF population were treated with DB1976 as well as alum, a pro‐inflammatory vaccine adjuvant that causes fibrosis (Kool et. al 2012). When each DB1976 + alum treatment group was compared with …
Mechanistic Examination Of Protist-Mediated Plant Growth Through The Comparative Development Of Medicago Truncatula, Shane Connolly
Mechanistic Examination Of Protist-Mediated Plant Growth Through The Comparative Development Of Medicago Truncatula, Shane Connolly
University Scholar Projects
Protists are known to increase plant growth through two main mechanisms: the microbial loop and the alteration of the root microbiome. The microbial loop is a nutrient recycling method in which protists provide inorganic nitrogen ions to the plant. Alteration of root microbiome leads to the removal of plant pathogens and shifting communities towards plant growth-promoting bacteria (PGPB). This study aimed to elicit which mechanism could produce the largest boost in shoot weight for Medicago truncatula. A series of microcosm experiments were explored in which M. truncatula was grown with variable microbiome structures to allow for mechanism differentiation. The …
Elucidating The Impact Of Sos-Response Timing In On Escherichia Coli Survival Following Treatment With Fluoroquinolone Topoisomerase Inhibitors, Stephanie Schofield
Elucidating The Impact Of Sos-Response Timing In On Escherichia Coli Survival Following Treatment With Fluoroquinolone Topoisomerase Inhibitors, Stephanie Schofield
Honors Scholar Theses
Antibiotic treatment failure is a public health crisis, with a 2019 report stating that roughly 35,000 deaths occur in the United States yearly due to bacterial infections that are unresponsive to antibiotics (1). One complication in the treatment of bacterial infection is antibiotic persistence which further compromises our battle to effectively treat infection. Bacterial persisters can exist in clonal bacterial cultures and can tolerate antibiotic treatment by undergoing reversible phenotypic changes. They can survive drug concentrations that their genetically identical kin cannot. Some persisters remain in a slow growing state and are difficult to target with current antibiotics. A specific …
Dynamic Transcriptomic Responses Of Circulating Immune Cells In Response To Subsequent Days Of Exercise Heat Stress, Soohyun Oh
University Scholar Projects
Acute exercise and chronic training have diverse effects on immune function that are still not well understood. There are remaining questions about how an acute bout of exercise, competition, or repeated training over a period affects an individual’s immune defense system. In a related study, there is evidence that acute exercise may serve as an adjuvant to enhance response to immune function as well as contradicting evidence, including our preliminary data (unpublished). Understanding the fundamental function and gene expression of circulating immune cells in response to acute exercise and in various contexts such as heat stress is critical in understanding …
A Dna-Peptide Crosslink (Dpc) Increases Mutagenicity In Sos-Induced Escherichia Coli, Alessandra Bassani
A Dna-Peptide Crosslink (Dpc) Increases Mutagenicity In Sos-Induced Escherichia Coli, Alessandra Bassani
Honors Scholar Theses
Bacteria, such as Escherichia coli, have an inducible system in response to DNA damage termed the SOS response. This system is activated when the replicative DNA polymerase (Pol) III encounters a lesion, uncouples from DNA helicase, and single-stranded DNA (ssDNA) accumulates at the replication fork. In this study, we investigated DNA-peptide crosslink (DpC), a common lesion that results from cross-linking of proteins or peptides, UV irradiation, and alkylating agents. To increase survival following formation of a lesion, the SOS response can utilize homologous recombination, translesion synthesis (TLS), or excision repair. With TLS, the levels of DNA Pol II, IV, …
Genetic Implications Of Language Acquisition, Marissa Renee Ciccarini
Genetic Implications Of Language Acquisition, Marissa Renee Ciccarini
Honors Scholar Theses
The argument about whether language acquisition is "nature" or "nurture" has been long debated. Linguists have concluded that it requires the two, but how much does language acquisition rely on nature? Children show the capacity to learn languages quickly and without much effort. While research suggests that infants absorb many visual and verbal cues in their environment, biological structures are the underlying component of how this knowledge is gathered and organized. The genetics that code for specific neurophysiological pathways affect how people interact with their environment and where information is stored, forming the basis for these biological structures. Genetic research …
Understanding The Relationship Between B Chromosomes And Nondisjunction In Drosophila Melanogaster, Ayushi Patel
Understanding The Relationship Between B Chromosomes And Nondisjunction In Drosophila Melanogaster, Ayushi Patel
Honors Scholar Theses
B chromosomes are supernumerary, heterochromatic genetic elements that are found in hundreds of different plant and animal species. Recently, B chromosomes were discovered in a stock of Drosophila melanogaster and are carried at a high copy number of 10-12 B chromosomes per cell. B chromosomes are not known to carry any active genes, but when placed in a wild-type genetic background, they cause a significant increase in the frequency of chromosome 4 missegregation during meiosis. This project aimed to understand the relationship between a female’s B chromosome copy number and how often she passes on too many (or too few) …
Enhancing Tomato Fruit Quality: Application Of Crispr/Dcas9-Mediated Methylation On The Pg Gene Promoter Region, Irena Komninakas
Enhancing Tomato Fruit Quality: Application Of Crispr/Dcas9-Mediated Methylation On The Pg Gene Promoter Region, Irena Komninakas
Holster Scholar Projects
Commercially produced tomatoes are typically harvested well before maturation in order to withstand domestic and international distribution. While this process ensures unspoiled goods, the nutritional value of the fruits have been curtailed as a result of premature harvesting. Previous research has found that the polygalacturonase gene (PG gene) is responsible for cell wall degradation of the tomato. In this study, CRISPR/dCas9 technology was employed to increase methylation levels in the promoter regions of the PG gene. This method is significant in that it epigenetically modifies the tomato genome using a technique that has the potential to develop non-genetically modified progeny …
