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 …

Validation Of Prmr Equations In A Non-Caucasian Sample – Ethnicity As A Variable In Predicting Resting Metabolic Rate, Erin N. Bannister
Graduate Research Theses & Dissertations
This study intends to identify a predictive resting metabolic rate (pRMR) equation that is predictive of the measured resting metabolic rate (mRMR) in a sample that includes a group of Black Americans. The handful of commonly used pRMR equations, such as the Mifflin- St. Jeor or Harris-Benedict equations, were created without defining the demographics of their populations, while validation of these equations is typically done with almost exclusively Caucasian subjects. Black and brown Americans require the same evidence of precision in predictions of daily energy needs as Caucasian Americans. When applied to non-Caucasian samples, these equations appear in the literature …

One Cell’S Trash Is Another Cell’S Treasure: The Role Of Exosomes In Stress Physiology Of The Brown Anole (Anolis Sagrei), Anna Kaza
Honors Program Theses
Exosomes are a type of extracellular vesicle that is produced by cells through an endosomal pathway and secreted into bodily fluids. Exosomes deliver bioactive cargo from their parent cells to target cells as a form of intercellular communication. While most research has studied exosomes in the context of disease, less is known about their role in normal physiology when disease is absent. Using the brown anole (Anolis sagrei) as a model organism, we investigated how stress exposure affects exosome concentrations in the plasma of anoles, and whether exosome release is necessary for the response to stress. We hypothesized that stress …
