The Impact Of Hypoxia And Androgen Inhibition On Prostate Cancer Cell Dedifferentiation And The Dna Damage Repair Response At Telomeres, Arooba Ayaz

Biomedical Sciences Theses & Dissertations

Long-term Androgen deprivation therapy (ADT) is used to treat Prostate cancer (PCa) but is often met with resistance & the development of Neuroendocrine (NE) PCa which is rarer but more aggressive. Antiandrogens are a part of ADT that work to inhibit androgen receptor in PCa cells. In vitro, PCa cells under long-term antiandrogen treatment become NE-like and adopt stem-like characteristics. The disruption of androgen signaling though the use of antiandrogens impacts many cellular processes that play a major role in cancer cell proliferation such as the DNA damage repair response (DDR) and telomere dysfunction. In vivo, PCa tumors have disorganized …

Computational And Ai Tools For Understanding Telomere-Associated Cancer Mechanisms, Eleni Adam

Computer Science Theses & Dissertations

Telomeres are the protective caps of the human chromosomes and are critical for genome stability. Dysfunctional telomeres caused by their erosion with age and cell proliferation as well as by defects in their maintenance is a major early event leading to genome changes and cancer. Subtelomeres possess the critical role of regulating adjacent telomeres. Due to their complex repeat structure and high variance from one person to another, these areas have not been analyzed in detail. We present a set of computational and machine learning tools to aid in the understanding of subtelomere structure and its rearrangements in cancer.

The Knowledge and Creativity Expo

Introduction: Reconstruction using Deep Inferior Epigastric Perforator (DIEP) flaps is standard for muscle-sparing breast restoration following mastectomy. Staging the procedure in two is becoming increasingly common and an option for community surgeons to decrease operation-specific time burden. We hypothesize that in our community hospital-based cohort, staged reconstruction will be associated with lower recovery burden and decreased complication risk.
Methods: This study was a retrospective single-surgeon cohort of patients receiving staged, immediate or unilateral DIEP breast reconstruction (N = 276) from 2011-2021. Procedure-level multivariate regression evaluated surgical time, Length of stay, opioid use (MME), and perioperative change. Patient-level multivariate regression assessed …

Exploring The Relationship Between Behavioral Health Early Prediction Model And Patient Outcomes In The Emergency Department, Karen M. Richendollar, Kathie M. Zimbro

The Knowledge and Creativity Expo

Problem: Emergency departments (EDs) are increasingly utilized for mental health (MH) care, often resulting in overcrowding and delayed access to specialized services. A significant proportion of MH patients are discharged without a psychiatric consult, raising concerns about safety and readmission rates. This trend places additional strain on already limited behavioral health resources and contributes to care delays for patients in acute crisis. Moreover, the lack of standardized discharge criteria for MH patients increases variability in care and may compromise patient outcomes.

Marzinke, Mark Mirochnick, Peter L. Anderson, Landon Myer, Connie Celum, Renee Heffron, Jenell Coleman, Dvora L. Joseph Davey, Lanxin Zhang, Max Von Kleist, Craig W. Hendrix, Jeremiah D. Momper, Robert Bies, Rachel K. Scott

CONRAD Publications

Cisgender women face an increased risk of HIV acquisition during pregnancy and postpartum. Oral pre-exposure prophylaxis (PrEP) with emtricitabine and tenofovir disoproxil fumarate (F/TDF) is recommended in pregnancy despite limited published pharmacokinetic (PK) and efficacy data during pregnancy. Altered PK during pregnancy may reduce prophylactic efficacy and necessitate higher adherence. Tenofovir alafenamide (TAF) is a newer tenofovir prodrug with higher tenofovir diphosphate (TFV-DP) exposure in peripheral blood mononuclear cells (PBMCs), but the prophylactic efficacy of F/TAF across different reproductive stages in women is understudied. We adapted a multiscale modeling framework to predict the prophylactic efficacy of F/TDF and F/TAF across …

Metabolic Reprogramming Following Mitochondrial Transfer Between Idh2-Mutant Chondrosarcoma Cells And A Normal B-Cell Line, Caleb Wyckoff, Christopher Osgood, Ellen Jing, Michael Stacey

Bioelectrics Publications

Background/Objectives: Chondrosarcoma, glioblastoma, acute myeloid leukemia, chronic lymphocytic leukemia, and cholangiocarcinoma cancers all contain mutations in the gene isocitrate dehydrogenase 2 (IDH2). The mutant IDH2 enzyme metabolizes alpha-ketoglutarate (αKG) into the potent oncometabolite D-2-hydroxyglutarate (D2HG) in the mitochondria of these cancers, leading to altered cellular metabolism. Emerging evidence suggests that mitochondrial transfer between cancer and recipient cells represents an important form of intercellular communication that may influence cellular metabolism. The presence of intercellular TNTs between IDH2-mutant chondrosarcoma cells motivated an investigation into mitochondria-associated physiological changes occurring during an intercellular exchange with immune cells. A mitochondrial transfer is a two-way …
