Francis Radics ’22
Major: Biochemistry
Faculty Mentor: Dr. John Breen, Chemistry and Biochemistry
Indicator displacement assays are based on the optical signal modulation of a noncovalently bound indicator upon dissociation by an analyte species. Our work has focused on exploring the lower detection limits for luminescent displacement assays for inorganic phosphate in seawater using complex ions containing two di(2-picolyl)amine ligands (also called DPA or bis(2-pyridylmethyl)amine), each coordinating a zinc cation. Following the work of B.D. Smith and coworkers, we have prepared three ligands by covalently attaching two DPA moieties, 2,6-bis(chloromethyl) benzene, and 2,6-bis(chloromethyl)-4-methylphenol, and 1,2-phenylenedimethylamine, for assays with 6,7-dihydroxy-4-methanesulfonic acid …
Investigation Of Oncogenic Ras And Endoplasmic Reticulum-Mitochondria Calcium Flux And Their Relationship In The Context Of Tumorigenesis, Emma Anderson
Senior Honors Theses
Intracellular calcium as a signaling molecule is a pervasive feature of cellular pathways, especially those that manage internal homeostasis and transitions through the cell cycle, so much so that regulated, responsive calcium flux between the endoplasmic reticulum (ER) and the mitochondria has been suggested to play a major role in cancer development. Another factor commonly implicated in tumorigenesis is RAS, an oncogene that controls signaling for many pathways that are also regulated by calcium. While both calcium and oncogenic RAS signaling are implicated in cancer development, possible links between them have yet to be determined. The identification of these links …

The coxsackievirus and adenovirus receptor (CAR) is an essential cellular protein that is involved in cell adhesion, cell signaling, and viral infection. The 8-exon encoded isoform (CAREx8) resides at the apical surface of polarized epithelia, where it is accessible as a receptor for adenovirus entering the airway lumen. Given its pivotal role in viral infection, it is a target for antiviral strategies. To understand the regulation of CAREx8 and determine the feasibility of receptor down regulation, the half-life of total and apical localized CAREx8 was determined and correlated with adenovirus transduction. Total and apical CAREx8 has a relatively short half-life …
