Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Cell fusion is a process that occurs in normal cells as well as in pathological cells. This process does not occur spontaneously, fusogens are required to mediate the process. Syncytin is one of the proteins that was determined to have fusogenic properties. Syncytin is a newly discovered transmembrane protein that is generally expressed in mammalian placenta and it is known for its role in cell fusion during placentation. The recent studies in Ugarova’s laboratory suggest syncytin is expressed in macrophages, thus it may be involved in macrophage cells fusion. This paper provides a literature review of syncytin protein; it also contains an experimental study conducted to determine syncytin expression on both RNA and protein level. The study was conducted on RNA and protein isolated from macrophages isolated from mouse peritoneum. Agarose gel electrophoresis and Western blot analysis were used to determine syncytin expression on RNA and protein level respectively. Using these methods, syncytin expression was determined at different time points during macrophage fusion. The results show that syncytin is not expressed in freshly isolated macrophages, but its expression is initiated during macrophage adhesion in the presence of IL-4.
