Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear. To address this, we performed in-depth proteomic profiling of ascites-derived exosomes from patients with PC, and we found that Galectin-3 was highly enriched in exosomes derived from malignant ascites. exosomal Galectin-3 was the crucial regulator of PC. Blockage of exosomal Galectin-3 significantly inhibited tumor metastases and prolonged overall survival. Exosomal Galectin-3 …

Colorectal cancer (CRC) is the third most common cancer worldwide, with rising prevalence among younger adults. Several lifestyle factors, particularly disruptions in circadian rhythms by light-dark (LD) shifts, are known to increase CRC risk. Epidemiological studies previously showed LD-shifts are associated with increased risk of CRC. To explore the mechanisms and interactions between LD-shift and intestinal aging, we investigated how the combination of LD-shifts and aging impacts colon carcinogenesis development. Our data showed that LD-shifts and aging increased colon tumorigenesis. Notably, LD-shift accelerated intestinal aging by altering aging-related pathways, such as intestinal barrier damage, accompanied by dysbiotic changes in the …

Conventional Versus 3d Bolus In Radiation Therapy, Madison Elizabeth Brdaric

Student Research Poster Presentations 2025

Radiation therapy is a form of cancer treatment that uses high-energy radiation to target tumors while protecting healthy tissue. Tumors near the skin can be difficult to treat because the surface does not get enough radiation. Boluses are tissue-equivalent materials that help focus radiation on the tumor. Conventional boluses work well on flat surfaces but struggle on awkward or uneven surfaces such as the nose or ear, resulting in air gaps that limit the efficiency of the treatment. 3D printed boluses solve this problem because they are custom-made to fit each patient's unique body structure. This allows the appropriate amount …

Characterizing And Targeting The Non-Catalytic Functions Of Phosphatase Of Regenerating Liver 3 (Prl-3) In Oncogenesis And Cancer Progression, Jeffery T. Jolly

Theses and Dissertations--Molecular and Cellular Biochemistry

Phosphatase of Regenerating Liver 3 (PRL-3) is frequently upregulated in various cancers and is associated with poor patient prognosis. Although traditionally studied for its phosphatase activity, PRL-3 also interacts with the CNNM family of magnesium transporters through its catalytic site, and these two functions are mutually exclusive at any given time. Most previous studies relied on a commonly used PRL-3 mutation that disrupts both phosphatase activity and CNNM binding, making it challenging to determine which function drives its oncogenic effects. To address this gap in the field, I utilized a panel of PRL-3 mutants that selectively disrupt either phosphatase activity …

Research outputs 2022 to 2026

In some cases, against medical advice, a person with cancer decides not to undergo any conventional, evidence-based cancer treatments including chemotherapy, radiotherapy hormone therapy and others. Estimates for treatment refusal range from 2.6% to 14.55%. Refusing evidence-based conventional cancer treatments is linked to rapid deterioration, poor prognosis and a higher risk of premature death. This study aimed to explore oncology health professionals’ experiences and views on why patients refuse standard cancer treatments. We employed an in-depth qualitative research design, adopting a social constructionist framework. Fourteen health professionals in Western Australia (WA) with experience working in oncology were interviewed. Four themes …

EVMS School of Health Professions Faculty Publications

[Introduction] Malnutrition and cachexia are common complications in cancer patients, and they negatively influence prognosis, treatment efficacy, and tolerability as well as quality of life [[1], [2], [3]]. Accurately identifying and effectively managing malnutrition and cachexia in this population remains a clinical challenge. Conventional validated screening tools may lack the sensitivity and specificity required for early detection and personalized intervention in diverse cancer types and treatment settings [4,5]. Over the last decade, the use of artificial intelligence (AI), including machine learning (ML) and deep learning (DL) strategies, has shown promising results in clinical nutrition, with the potential to revolutionize nutritional …

Synthesis Of Tu100 Analogs And Biological Assays, Feyisope Tonye Oladapo

College of Graduate Studies: Theses & Dissertations

TU100 (14-methyl-5H-5,12-epiminobenzo[4,5]cyclohepta[1,2-b]naphthalene-6,11,13(12H)-trione) exhibits exceptional chemotherapeutic properties. It operates via a distinct mechanism that triggers cell death to create cytotoxic effects while concurrently inhibiting topoisomerase I and II. Its efficacy rivals that of well-known chemotherapeutic drugs like Daunorubicin. The distinctive characteristics of TU100 have led to initiatives aimed at creating structurally similar compounds to discover even more effective bioactive alternatives.

The analog synthesis incorporated quinoxaline or its derivatives (diphenyl quinoxaline, dipyridinyl quinoxaline, and dibenzophenazine-10,13-dione) that have been shown to have promising chemotherapeutic effects. Synthesizing the hetero naphthoquinones required a multi-step synthetic process, so quinoxaline/ derivatives intermediates are first prepared, then the …

Potentiation Of Gelonin Cytotoxicity By Pulsed Electric Fields, Olga N. Pakhomova, Eleni Zivla, Giedre Silkuniene, Mantas Silkunas, Andrei G. Pakhomov

Bioelectrics Publications

Gelonin is a ribosome-inactivating protein with extreme intracellular toxicity but poor permeation into cells. Targeted disruption of cell membranes to facilitate gelonin entry is explored for cancer and tissue ablation. We demonstrate a hundreds- to thousands-fold enhancement of gelonin cytotoxicity by pulsed electric fields in the T24, U-87, and CT26 cell lines. The effective gelonin concentration to kill 50% of cells (EC₅₀) after electroporation ranged from <1 nM to about 100 nM. For intact cells, the EC₅₀ was unattainable even at the highest gelonin concentration of 1000 nM, which reduced cell survival by only 5–15%. For isoeffective electroporation treatments using 300 ns, 9 µs, and 100 µs pulses, longer pulses were more efficient at lowering gelonin EC₅₀. Increasing the electric field strength of 8, 100 µs pulses from 0.65 to 1.25 kV/cm reduced gelonin EC₅₀ from 128 nM to 0.72 nM. Conversely, the presence of 100 nM gelonin enabled a more than 20-fold reduction in the number of pulses required for equivalent cell killing. Pulsed electric field-mediated delivery of gelonin shows promise for hyperplasia ablation at concentrations sufficiently low to minimize or avoid systemic toxicity.

Physical Ablative Methods And Cancer Cell Death: Implications For Immunity And Therapies, Alessandra Rossi, Claudia Muratori

Bioelectrics Publications

Surgery has traditionally been a cornerstone in cancer treatment, yet its feasibility can be limited by factors such as tumor location and patient health conditions. When surgery is not viable, thermal and pulsed electric field (PEF)-based ablation technologies offer valuable alternatives. Emerging evidence suggests that these approaches not only target tumors effectively but also stimulate antitumor immune responses. In this review, we begin by examining the distinctive features of hyperthermic treatments (radiofrequency and microwave ablation), cryoablation, and PEF-technologies. Subsequently, we discuss the mechanisms of cell death, stress responses, and release of danger signals triggered by these diverse ablation technologies. Finally, …

Department of Obstetrics & Gynecology Faculty Publications

Several diseases affect the female reproductive system, and both disease factors and treatments impact its integrity and function. Consequently, understanding the mechanisms of disease occurrence and exploring treatment methods are key research focuses in obstetrics and gynecology. However, constructing accurate disease models requires a microenvironment closely resembling the human body, and current animal models and 2D in vitro cell models fall short in this regard. Thus, innovative in vitro female reproductive system models are urgently needed. Additionally, female reproductive system diseases often cause tissue loss, yet effective tissue repair and regeneration have long been a bottleneck in the medical field. …

Fgf19 Facilitates Metastatic Phenotypes In Colorectal Cancer, Joseph W. Nolff

Graduate Thesis and Dissertation post-2024

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. With 154,000 new cases estimated in 2025, there is an increased need for early screening to detect CRC prior to metastasis. Our laboratory has focused on enteroendocrine hormone Fibroblast Growth Factor-19 (FGF19) as it is overexpressed in a subset of CRC tumors. FGF19 is an intestinal-derived hormone involved with lipid homeostasis when bound to its receptor, Fibroblast Growth Factor Receptor-4 (FGFR4). Our objective focuses on FGF19 contribution towards an epithelial-to-mesenchymal transition (EMT) and overall metastatic properties including rapid proliferation and/or increased cell motility. Immunofluorescence was …

Effects Of Round-Up On The Environment, Sandra J. Marcu
