Chromatin Pattern Quantification For The Differentiation Of White Blood Cells, Paul Young, Ryan Cordner, Abigail Gordhamer
Annual Research Symposium
Nuclear chromatin patterns have been used historically to distinguish between different developmental stages and lineages of white blood cells. While it is common to characterize cells based on arbitrary ‘open’ or ‘closed’ chromatin patterns, quantification of chromatin data is lacking. By extracting nuclei from a database of white blood cells and running fractal analyses using TWOMBLI, we were able to produce meaningful data quantifying chromatin patterns. Our data were put through a random forest algorithm which grouped each point based on relationship probability. The algorithm compared immature and mature cell types as well as cells of similar maturity and differing …

Pharmacognosy And Trichomoniasis: A Scoping Review Protocol, Claire Hartwell, Melanie Arslanian, Brad Haubrich
Annual Research Symposium
Trichomoniasis, also called “trich”, is the most common non-viral sexually transmitted infection (STI). Its etiological agent is the protozoan parasite Trichomonas vaginalis, against which first-line antiparasitics usually work. However, resistance is on the rise. Trich has traditionally been considered a nuisance infection, with many (particularly AMAB patients) being asymptomatic. But research in recent years has begun to unravel correlations of trichomonal infections with a myriad of comorbitidies, including infertility, cancers, the pathogenesis of AIDS, and pelvic inflammatory disease (PID). Between the rise of drug resistance and the incidence of these comorbidities, new treatments are needed. In this work, we are …

Detection And Relative Quantitation Of Changes In Gene Expression Of Hippo Proteins In Doxorubicin-Exposed Human Cells By Rt-Qpcr, Lillian Fleisher, Tricia Domingo, Christopher So, Stephen Lee
Annual Research Symposium
The HIPPO signaling pathway plays a key role in cell proliferation and tumor suppression. It consists of serine/threonine kinase cascades, including MST1/2, LATS1/2, YAP, and TAZ. When the HIPPO pathway is activated, gene expression is altered. Dysfunction of the activity of this cascade may contribute to cancer development and chemoresistance. FAT4 is an intracellular protein that may regulate the HIPPO signaling. The purpose of this study is to determine the relative changes of mRNA of the HIPPO pathway members and FAT4 in doxorubicin-treated and vehicle-treated in vitro cell lines.

The gut and local esophageal microbiome progressively shift from healthy commensal bacteria to inflammation-linked pathogenic bacteria in patients with gastroesophageal reflux disease, Barrett’s esophagus, and esophageal adenocarcinoma (EAC). However, mechanisms by which microbial communities and metabolites contribute to reflux-driven EAC remain incompletely understood and challenging to target. Herein, we utilized a rat reflux-induced EAC model to investigate targeting the gut microbiome–esophageal metabolome axis with cranberry proanthocyanidins (C-PAC) to inhibit EAC progression. Sprague-Dawley rats, with or without reflux induction, received water or C-PAC ad libitum (700 μg/rat/day) for 25 or 40 weeks. C-PAC exerted prebiotic activity abrogating reflux-induced dysbiosis and mitigating …
