Effects Of Fatty Acids From Coconut And Olive Oil On Expression Of The Hmg1 Gene And Feeding Behavior In Tetrahymena Thermophila, Amelia Konen, Taryn Stewart Apr 2019

Effects Of Fatty Acids From Coconut And Olive Oil On Expression Of The Hmg1 Gene And Feeding Behavior In Tetrahymena Thermophila, Amelia Konen, Taryn Stewart

Carroll College Student Undergraduate Research Festival

HMG-CoA reductase is an enzyme involved in the biosynthetic pathways of sterols in many different organisms. The gene in Tetrahymena thermophila which codes for this protein is HMG1, and has many homologs across many other organisms, from fungi to humans. For this project, we wanted to look at the effect of external fatty acids from coconut and olive oil on the expression of HMG1 in T. thermophila. Previous research has shown that exposure to unsaturated oils result in decreased cholesterol levels. We hypothesized that if T. thermophila are introduced to saturated fats and unsaturated fats, they would exhibit a respectively ...


The Effect Of Alcohol On Pfk1 Gene Expression And Feeding Activity In Tetrahymena Thermophila, Evelyn Sowers, Alex Skoulis Apr 2018

The Effect Of Alcohol On Pfk1 Gene Expression And Feeding Activity In Tetrahymena Thermophila, Evelyn Sowers, Alex Skoulis

The purpose of this experiment was to test whether alcohol induces starvation conditions in Tetrahymena thermophila. Prior research has shown that exposure to alcohol results in decreases in both the frequency of feeding and overall growth. For this experiment, it was hypothesized that these effects are due to a lack of energy available in the organism for feeding. This hypothesis was tested by monitoring food vacuole formation and expression of the PFK-1 gene in Tetrahymena that were exposed to alcohol. The PFK-1 gene was chosen because its encoded protein plays an essential role in cellular metabolism. For the experiment, control ...
