Political Apathy Among Colleges StudentsYoung Americans are often stereotyped as one of the most politically disconnected demographics in the country. Low rates of voter turnout help characterize this age group as indifferent and apathetic. This makes the voting behavior of young people an incredibly important topic of study for political scientists. This is especially true in the wake of the 2016 presidential election. This research focused on American citizens aged 18-24. The research aimed to determine whether political apathy among this age group has increased or decreased since 2012. The study consisted of a comparison of responses from two different surveys. Data from the first survey was drawn from a nationwide telephone poll conducted by the Center for Information and Research on Civic Learning and Engagement (CIRCLE). This survey was conducted shortly after the 2012 presidential election. This data was compared to an identical survey administered online to a sample of students at Augusta University following the 2016 presidential election. Differences in sample sizes limited the ability to analyze comparisons between the two surveys. However, analysis of the 2016 dataset points to a low sense of political apathy among students sampled at Augusta University.
Progress City - An Honors Thesis ExhibitionThe purpose of this project is to explore the way sculpture can visually represent history. Progress City is an art exhibition that focuses specifically on the time period during which America transitioned from an industrial to a service-based economy (1950s - 1970s) and the effects this departure had on cities throughout the Southeast. The exhibition comprises a series of twelve buildings with sides featuring screen printed images of actual abandoned and dilapidated structures. Each building reflects an industry or trade that was once considered vital to the growth of southern communities. These buildings are juxtaposed alongside a collection of found objects that have either a direct or indirect correlation to businesses that once occupied the actual structures. For example, a series of empty food packaging boxes from the 1950s are set alongside a structure featuring screen printed images of an abandoned market facade. By juxtaposing the found objects, now considered outdated, alongside a corresponding abandoned building, the viewer is able to see first-hand the effects progress has had on southern cityscapes.
The Structural and Functional Properties of a Splice Variant of ADCY7 Gene in Human Pancreatic CancerAlternative splicing of mRNA precursors is a regulated process of gene expression in eukaryotic cells. It provides cells with the opportunity to create protein isoforms of different functions from a single gene. Cancer cells often take advantage of this process to produce proteins that promote growth and survival. Cyclic adenosine monophosphate (cyclic AMP) is a second messenger that has shown to suppress migration and invasion of pancreatic ductal adenocarcinoma cells. Cyclic AMP is formed from cytosolic ATP by the enzyme adenylyl cyclase (AC). There are ten isoforms of ACs; nine are anchored in the plasma membrane and one is soluble. Our goal was to find alternative splice variants of transmembrane AC isoforms in pancreatic cancer. We found a possible splice variant of type VII adenylyl cyclase (ADCY7) in human healthy pancreatic, adjacent non-tumor, tumor tissues, two pancreatic cancer cell lines HPAC and PANC-1, epithelial duct cell line PDEC, but not in isolated human pancreatic acini (the exocrine part of the pancreas). Further research will be carried out to study the structural and functional properties of the splice variant of human ADCY7.
Structural, Kinetic and Functional Properties of CAP1/AC ComplexesThe major cause of death in pancreatic cancer is due to metastases; therefore, it is important to study the mechanism by which the pancreatic cancer cells migrate and invade. This would help advance therapeutics and ultimately help prolong survival. Adenylyl cyclase-associated protein 1 (CAP1) is a scaffold protein that is involved in the regulation of actin microfilament formation, which ultimately leads to cell migration and invasion. CAP1 binds to G-actin inhibiting polymerization. We first tested whether CAP1 binds to adenylyl cyclase (AC) by performing co-immunoprecipitation. We found that CAP1 not only interacts with G-actin, but also with a number of AC isoforms: AC1, AC3, AC4 and AC7. Further studies need to be done to determine how CAP1/AC/G-actin interact and the impact of these interactions on the invasive behavior of pancreatic cancer cells.
