Cigarette smoke promotes bladder tumor growth by enhancing cancer cell survival and proliferation through smoke mediated carcinogens. FASN, a key enzyme in fatty acid synthesis, is dysregulated in many cancers and correlates with aggressive phenotypes. In this study, we demonstrate elevated fatty acid levels and FASN specifically in smokers with bladder cancer. Elevated FASN under smoke exposure imparted epigenetic alterations, particularly histone acetylation, impacts DNA repair and DNA-binding transcription factors which regulate metabolic pathways. Under cigarette smoke, bladder cancer cells undergo a metabolic shift, utilizing glutamine as a major carbon source through reductive carboxylation to fuel fatty acid biosynthesis via …

Characterization Of Catechol-Type Siderophore(S) From P. Mosselii Cfml 90-83, Kemper R. Rasnake Aug 2026

Characterization Of Catechol-Type Siderophore(S) From P. Mosselii Cfml 90-83, Kemper R. Rasnake

Electronic Theses and Dissertations

Iron is essential for many biological processes, where it is used as a cofactor. Even though it is abundant in the Earth’s crust, it is in an insoluble form unavailable to microorganisms in the soil. To overcome this, bacteria produce siderophores, which are secondary metabolites that have a high affinity for iron. This allows bacterial cells to obtain insoluble iron that is essential for survival. Pseudomonas mosselii, a Gram negative bacterium, was isolated from soil. It was selected for further analysis as it was found to produce siderophore(s) under iron-limited conditions, which have not been characterized previously. Therefore, we aimed …


Ai-Driven Segmentation And Volumetric Response Modeling Of Liver Regions To Radiotherapy, Aashish Chandra Gupta Aug 2026

Ai-Driven Segmentation And Volumetric Response Modeling Of Liver Regions To Radiotherapy, Aashish Chandra Gupta

Dissertations and Theses (Open Access)

In liver-directed radiotherapy (RT), liver regions receiving higher doses typically undergo atrophy while contralateral/adjacent lower-dose regions may exhibit compensatory hypertrophy through regeneration of healthy tissue. Optimizing the RT plan to promote regional hypertrophy while minimizing the risk of developing atrophy has the potential to enhance post-RT liver function and long-term survivorship. However, current clinical practice largely relies on global liver dose-volume metrics during RT-planning, which may obscure favorable dose-response correlation and limit actionable guidance for clinicians. Therefore, we hypothesized that post-RT regional liver response is governed by a combination of region-specific dose-volume and patient clinical features, and that these responses …

Purpose: Magnetic resonance imaging using hyperpolarized (HP) [1-13C]-pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi-quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular metabolism. A validated pharmacokinetic (PK) model for analysis of intracellular pyruvate metabolism is needed to enhance the accuracy of quantitative metrics and clinical translation of metabolic MRI using HP pyruvate.

Methods: A PK model with two physical compartments and two chemical pools was developed to analyze the conversion of labeled pyruvate into lactate in vitro. …

GLP-1RAs are increasingly used for their glucose-lowering and weight-management effects, but many patients discontinue them. In this narrative review we aim to review real-world, quantitative and qualitative GLP-1RA discontinuation, adherence, and persistence evidence as it aligns with an established conceptual framework for understanding medication adherence in noncommunicable chronic disease. Many inconsistencies exist in how discontinuation, adherence, and persistence are studied in this literature. Few qualitative studies have focused on discontinuation of GLP-1RAs. Quantitative approaches often focus on medication-related factors and more superficial aspects of socioeconomic and condition-related factors. Very few studies encompass all 5 dimensions of the medication adherence conceptual …

Notch Signaling Regulates The Secretion Of Pro-Metastatic Factors In Extracellular Vesicles In Liposarcoma, Menchus Quan, Yi-Kai Liu, Ying Zhao, Madeline Kay, Kai Sun, Timothy P Gavin, Raphael E Pollock, W Andy Tao, Shihuan Kuang

The Brown Foundation: Institute of Molecular Medicine

Notch signaling is an emerging regulator of liposarcoma (LPS), but its role in mediating communication with the tumor microenvironment (TME) is unclear. Here, we investigate how Notch activation (NICD overexpression) alters the proteomes of LPS-derived extracellular vesicles (EVs). We used quantitative mass spectrometry to profile the EV proteome in multiple contexts: cultured LPS cells, LPS tumor, circulating EVs of LPS-bearing mice, and human LPS samples. We found that Notch signaling increases the secretion of EV proteins that favor tumor progression and metastasis but suppresses immune responses in murine LPS cells. Overlapping murine and human LPS data identifies 18 proteins that …

The Brown Foundation: Institute of Molecular Medicine

Macrophages orchestrate tissue remodeling, inflammation, and metabolic dysfunction in obesity, but the role of macrophage-intrinsic extracellular proteolysis in immunometabolic regulation remains unclear. Matrix metalloproteinase-14 (MMP14), a membrane-bound protease, is strongly induced during monocyte-to-macrophage differentiation and further elevated in adipose tissue macrophages from high-fat diet (HFD)-fed mice. Pharmacological inhibition or myeloid-specific deletion of Mmp14 impaired macrophage differentiation, proliferation, migration, phagocytosis, and inflammatory activation in response to obesity-associated adipose tissue signals. Mechanistically, MMP14 promoted inflammatory programming by increasing endotrophin generation and enhancing TLR4-NFκB signaling. MMP14 also reprogrammed macrophage lipid metabolism by suppressing lipolysis and promoting lipid accumulation, altering metabolic communication with neighboring …

Kras-Independent Factors Drive Pi3k Signaling And Circumvent The Necessity Of Kras-Driven Pi3k Activation In Pdac, Lucas Christopher Bialousow Jul 2026

Kras-Independent Factors Drive Pi3k Signaling And Circumvent The Necessity Of Kras-Driven Pi3k Activation In Pdac, Lucas Christopher Bialousow

MUSC Theses and Dissertations

Pancreatic ductal adenocarcinoma (PDAC) has one of the lowest five-year survival rates among cancers and is characterized by near-ubiquitous occurrence of oncogenic KRAS mutations. Oncogenic KRAS activates several downstream pathways, including ERK 1/2 MAPK and PI3K, which are critical for PDAC. However, accumulating evidence suggests that PI3K activity can be maintained independent of oncogenic KRAS. The high prevalence of KRASG12R in PDAC challenges the prevailing model of KRAS-driven PI3K activation, as this mutant is defective in direct engagement with PI3Kα. These observations raise important questions regarding how PI3K signaling is sustained in PDAC. Here, we investigated KRAS-independent mechanisms that …

Respiratory syncytial virus (RSV) causes millions of lower respiratory tract infections (LRTIs) in young children, older adults, and immunocompromised populations every year. RSV infection initiates in the upper respiratory tract and can progress to the lower airways, resulting in bronchiolitis, pneumonia, and even death. RSV primarily infects epithelial cells apically, but we hypothesized that basolateral exposure of the respiratory epithelium could provide an alternative mechanism of infection that contributes to LRTI development. Using a human nose organoid-air-liquid interface (HNO-ALI) model, we performed apical and basolateral inoculations with contemporaneous RSV strains (RSV/A/Ontario [RSV/A/ON] and RSV/B/Buenos Aires [RSV/B/BA]) representing the two RSV …

Proteogenomic analyses have identified an association between LIG1 (DNA Ligase I) loss and chemotherapy resistance in a subset of triple negative breast cancer (TNBC) enriched for TP53 mutations. Here, we demonstrate that co-occurrence of TP53 mutations and LIG1 loss is associated with upregulated DDR activity, including homologous recombination, likely contributing to reduced platinum sensitivity. Unbiased genetic and monotherapy drug screens identified PARP inhibitors (PARPi) as a potential treatment for LIG1-depleted tumors; however, the increase in sensitivity was modest and lower than that observed in TNBC models with homologous recombination deficiency. Subsequently, a screen of PARP inhibition in combination with each …

Accumulating research implicates sleep disruption in perinatal anxiety and related symptoms, including obsessive-compulsive symptoms. We examined the associations among insomnia symptoms and sleep duration with perinatal anxiety, obsessive beliefs, and obsessive-compulsive symptoms and the moderating role of coping from pregnancy through postpartum.

Methods: A sample of 231 women (agemean = 32.97 ± 4.36 years; 74% white) completed interview and self-report measures of sleep, coping, perinatal anxiety, obsessive beliefs, and obsessive-compulsive symptoms in early …

Background: Cancer immunotherapies have significantly improved treatment efficacy and patient survival by exploiting antigen-specific T cells to eliminate cancer cells. However, current approaches for identifying and isolating antigen-specific T cells typically require prior knowledge of target antigens, limiting discovery, and reducing the ability to consistently detect rare tumor-reactive T cells. We therefore sought to develop an unbiased platform for the identification and enrichment of antigen-specific T cells using naturally processed and presented tumor antigens.

Methods: We developed ATTACH (Assessment of T cells Tethered to Antigen Class I Histocompatibility), a microfluidic platform that applies controlled shear stress and leverages tumor cells …
