The Effects of Warming Temperatures on Rad51 Expression in Tetrahymena thermophila
(2018-07-01)Our experiment explored whether raised temperatures affected expression of the Rad51 gene in Tetrahymena thermophila. Our hypothesis was that raised temperatures would result in a decrease in expression of the Rad51 gene. ... -
Effect of EGTA on SIT1 Scramblase Gene Expression and Cell Growth in Tetrahymena thermophila
(2018-07-01)Scramblase is an enzyme that facilitates the movement of newly synthesized phospholipids from the cytosolic side to the extracellular side of the lipid bilayer. This process is vital for cell membrane repair and growth. ... -
The Effect of Metal Pollutants on Cell Growth and TTHERM0058490ExpressioninT etrahymenathermophila
(2018-07-01)In this experiment, we sought to answer the following question: Do higher levels of metal exposure affect expression of the TTHERM 00584900 gene in Tetrahymena thermophila? The TTHERM 00584900 gene produces an ATP-binding ... -
Impacts of Environmental Motion on CDC2 Expression and Cell Growth in Tetrahymena thermophila
(2018-07-01)In this experiment, the eect of constant motion on expression of the cell cycle control gene CDC2 was examined in the organism Tetrahymena thermophila. We hypothesized that CDC2 expression would decrease with a corresponding ... -
Effects of Fatty Acids from Avocados on Expression of the HMG1 Gene in Tetrahymena thermophila
(2018-07-01)The enzyme 3-Hydroxy-3-Methyl-Glutaryl-CoA Reductase (HMG) HMG catalyzes the ratelimiting step in the biosynthesis of cholesterol and is a common drug target for cholesterol reduction. Previous studies in rats have shown ... -
Manganese Toxicity in the Dopamine Synthesis Pathway in Drosophila melanogaster
(2018-07-01)Manganese is prevalent in Montana, and Manganese toxicity symptomatically resembles Parkinsons disease. The goal of this project was to determine whether exposure to high levels of Manganese affects the Dopamine synthesis ... -
Effects of Sulfur Dioxide on abdA Gene Expression and Larval Development in Drosophila melanogaster
(2018-07-01)In this experiment, we tested the effects sulfur dioxide exposure had on abd-A gene expression and larval development in Drosophila melanogaster. Previous studies showed that sulfur dioxide exposure inhibits development ... -
Effect of Nitrate Pollution on Tetrahymena thermophila
(2018-07-01)The question under investigation in this project was: Does an elevated concentration of nitrates have a negative eect on cell growth and expression of the CDC16 gene in the organism Tetrahymena thermophila? Exposure of ... -
Effect of Alcohol on PFK1 Gene Expression and Feeding Activity in Tetrahymena thermophila
(2018-07-01)The purpose of this experiment was to test whether alcohol induces starvation conditions in Tetrahymena thermophila. For this experiment, it was hypothesized that alcohol induces starvation due to a lack of energy available ... -
Analysis of FBP1 Gene Expression in UV Light-exposed Tetrahymena thermophila Cultures
(2018-07-01)In this study, Tetrahymena thermophila cultures were exposed to an acute treatment of UV light and expression of the FBP1 gene was examined. The FBP1 gene encodes Fructose- 1,6-biphosphatase which plays an important role ... -
UV Light Exposure and Tetrahymena thermophilia: Expression of the PHR2 Gene
(2018-07-01)The PHR2 (photolyase repair) gene functions in the repair of DNA in Tetrahymena thermophila. It was hypothesized that when Tetrahymena cultures are exposed to UV light, increased expression of PHR2 would occur in response ... -
Effects of the Everyday Toxin, Titanium Dioxide, on Drosophila melanogaster Nervous System Development
(2018-07-01)Titanium dioxide (TiO2) is a widely used compound found in everything from food packaging to sunscreens. When ingested, TiO2 is readily transported across membranes and efficiently stored within cells. Previous studies ... -
Put Your Phone Down: Effects of Cellular Radiation on Drosophila melanogaster
(2018-07-01)In this project, we aimed to answer the question: Does cellular radiation affect offspring production and expression of the Rad51 gene in the organism Drosophila melanogaster? It was hypothesized that if Drosophila larvae ... -
Effect of Potassium Bromate on OXR1 Gene Expression and Cell Growth in Tetrahymena thermophila
(2018-07-01)The purpose of our experiment was to answer the question: Does oxidative damage, induced by potassium bromate (KBrO3), affect growth rate and expression of the OXR1 gene in Tetrahymena thermophila? Potassium Bromate was ... -
Effects of UVB light on Tfb5 gene expression in developing Drosophila melanogaster
(2018-07-01)UVB light is known to cause DNA damage that results in gene mutations. Most regions of DNA damage are corrected using Nucleotide Excision Repair mechanisms (NER). In Drosophila melanogaster, the Tfb5 gene codes for an ... -
Analyzing ATP Synthetase F1 Expression in Heat-Exposed Tetrahymena thermophila
(2018-07-01)In this study, we investigated the effect of temperature on expression of the ATP1 gene in the organism Tetrahymena thermophila. We hypothesized that expression of the ATP1 gene would increase as we increased temperature. ... -
Analysis of Antimicrobial Peptide Efficacy Against Chytridiomycosis from Skin Secretions of Columbia Spotted Frogs (Lithobates luteiventris)
(2018-04-01)Amphibian populations have been declining in size in recent years. A major contributing factor to this decline is the fungal disease chytridiomycosis. Chytridiomycosis occurs when the zoospores of the fungus Batrachochytrium ... -
