STUDENT SCHOLAR SYMPOSIUM SPRING 2020 TUESDAY, MAY 5 AND WEDNESDAY, MAY 6 SPRING SESSION ABSTRACT VOLUME Message from the Director Greetings and welcome to the Spring 2020 Chapman University Student Scholar Symposium! Student Scholar Symposium celebrates the remarkable scholarship and creativity conducted by Chapman students. Student Scholar Symposium is sponsored by the Center for Undergraduate Excellence, which is the first stop and the central hub for students to learn about and engage in undergraduate research and creativity activity; and to discover the wide range of prestigious external scholarships available. Our student presenters reflect the diversity of academic and creative disciplines thriving within the Chapman community. This year we have moved the Spring Student Scholar Symposium to this virtual platform where you can attend a live Microsoft Teams meeting to connect with the student and discuss their research/creative activity. The virtual symposium allows our students multiple ways to showcase their research and creative project, consisting of posters, oral, visual arts, performing arts, and film and media presentations. Our virtual symposium would not have been possible without the extraordinary effort by the CUE staff, Lisa Kendrick, Operations Manager, and Jackie Coyne, Administrative Assistant, who designed and developed the event. A special thanks to both of them. Thanks to all the student presenters and their faculty mentors!

The enzyme produces ammonia under ambient conditions, using the free energy of ATP to drive dinitrogen reduction. The most common form of nitrogenase is molybdenum nitrogenase (Mo-nitrogenase). Mo-nitrogenase is inhibited by the ubiquitous pollutant carbon monoxide (CO). To prevent inhibition of Mo-nitrogenase by CO, nitrogen fixing bacteria produce the protein CowN. In presence of CowN, Mo-nitrogenase avoids inhibition by CO and remains active. However, the mechanism by which CowN protects Mo-nitrogenase is unknown. Enzymatic assays suggest that CowN and Mo-nitrogenase interact with a Kd of approximately 5-10 µM. Here, we present data from crosslinking and pulldown assays that were used to determine how CowN interacts with Mo-nitrogenase. Crosslinking assays using the heterobifunctional crosslinker EDC showed no binding between CowN and Mo-nitrogenase in presence or absence of CO gas. Pulldown assays using Ni- NTA resin with a His-tagged CowN bait also did not show significant binding between CowN to Mo- nitrogenase. These assays indicate that CowN may not have a strong binding enough affinity to Mo- nitrogenase to be detected by crosslinking or pulldown assays. Future work will investigate potential nitrogenase-CowN interaction using fluorescence anisotropy. Exploring The Effect Of The Diarylpentanoid ca27 On The Degradation Of The Androgen Receptor In Prostate Cancer Cells Presenter(s): Emma Beale Advisor(s): Dr. Marco Bisoffi The present study addresses a possible mechanism of action for the diarylpentanoid curcumin analog 27 (ca27), which has been shown to downregulate the androgen receptor (AR) in prostate cancer (PCa) cells. Prostate cells, both normal and cancerous, express the AR, which functions as a hormone-induced cytoplasmic/nuclear receptor and transcription factor promoting cell growth and survival. In PCa, AR expression and activity are overexpressed, and the AR is a major oncoprotein leading to uncontrolled cell growth. ca27 is a synthetic diarylpentanoid analog of the natural product curcumin. Previous research in Dr. Bisoffi’s lab has shown that ca27 downregulates AR expression at low micromolar concentrations in prostate cancer cells. However, the mechanism of action is unknown. The goal of the present work is to determine at what step of the central biological dogma ca27 acts to downregulate AR expression. Specifically, we hypothesize that ca27 interferes with AR protein stability by enhancing its degradation. Using specific inhibitors of transcription, translation, and degradation, applied to human androgen- dependent LNCaP prostate adenocarcinoma cells, preliminary data is presented based on the method of sodium dodecyl sulfate gel electrophoresis (SDS-PAGE) followed by immunological detection by Western blotting and quantitative reverse transcription polymerase chain reaction (qRT-PCR). Our preliminary findings indicate that ca27 is a mediator of protein degradation. A better understanding of the mechanism of action of ca27 with respect to its activity to downregulate AR expression will build the foundation for the development of organic small molecules as therapeutic candidates in the clinical management of PCa. 6 Poster Presentations - Session I Tuesday, May 5 | 9:00AM-10:30AM Characterizing the Ganglioside Content in Human Intestinal Epithelial Cells and Extracellular Vesicles With or Without Supply of Exogenous Gangliosides Presenter(s): Jordan Jernigan Advisor(s): Dr. John Miklavcic Dietary fats play a role in the development, progression, and treatment of chronic diseases. Gangliosides are a type of lipid, or fat, found in all human tissues. Both healthy and diseased cells undergo intercellular communication by secreting vesicles into
