Faculty, Staff and Student Publications

Rapid advances in single-cell RNA sequencing (scRNA-seq) technology have enabled the investigation of gene expression changes at the single-cell level, particularly for elucidating the heterogeneity among cells and complex biological processes. This technique reveals subtle molecular differences within individual cells, thereby offering a unique viewpoint for the investigation of cell cycle progression, cellular differentiation, and disease pathogenesis. However, accurately identifying and analyzing cell cycle dynamics in scRNA-seq data remains challenging due to the complexity of the data and the subtle differences between cell states. To address this challenge, we developed the integrated Sinusoidal and Piecewise AutoEncoder (SPAE), an autoencoder-based piecewise …

Introduction – Pain assessment remains challenging in healthcare settings in patients who are unable to self-report their pain. More than 50% of individuals with dementia and other forms of cognitive impairment (CI) experience pain daily. However, pain is frequently overlooked and inadequately assessed by healthcare professionals due to their lack of knowledge and guidelines to inform pain assessment. Pain is also a leading cause of hospital presentation and inappropriate pain assessment can impact on pain management and compromise safe and quality care. Evidence-based guidelines that inform appropriate pain assessment and management are therefore essential. This scoping review aimed to explore …

Cancer therapy-related cognitive impairment (CTRCI) is a debilitating neurotoxic condition adversely impacting cancer patients during and post-cancer treatments. The cancer treatments linked to CTRCI include chemotherapy, hormone therapy, targeted therapy, and immunotherapy. Despite CTRCI severely affecting the psychological and social, cognitive functions, and the overall quality of life of cancer survivors, no effective medications are available currently. Our prior studies have indicated hippocampal tyrosine phosphatase protein tyrosine phosphatase receptor type O (PTPRO) as a putative target for CTRCI. However, phosphatase is historically considered undruggable, and delivering drugs across the blood-brain barrier (BBB) is challenging. Here, we developed a novel delivery …

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 …


Mapping And Modeling Threat-Evoked Brain States After Early Life Adversity, Taylor W. Uselman Jul 2026

Mapping And Modeling Threat-Evoked Brain States After Early Life Adversity, Taylor W. Uselman

Biomedical Sciences ETDs

Early life adversity (ELA) increases lifelong neuropsychiatric vulnerability. Yet how ELA reorganizes brain-wide activity and circuit coordination across later experience remains unclear. This dissertation tests the hypothesis that ELA alters adult brain-wide activity and responses to threat through disrupted coordination among neural systems that regulate emotional experience, including prefrontal-limbic and monoaminergic systems. Longitudinal manganese-enhanced MRI of adult mice exposed to standard or fragmented early care, combined with computational processing and statistical modeling, quantified brain states before, during, and long after innate predator threat. These studies established that acute threat evokes large-scale, distributed brain activity that evolves over time. ELA potentiates …


Uv Damage Mapping Reveals Different Impacts Of Xpd Mutations On Global Genomic And Transcription-Coupled Dna Repair, Allyson Hoag Jul 2026

Uv Damage Mapping Reveals Different Impacts Of Xpd Mutations On Global Genomic And Transcription-Coupled Dna Repair, Allyson Hoag

Biomedical Sciences ETDs

Nucleotide Excision Repair (NER) is a fundamental cellular process that removes bulky and helical distorting lesions from the genome through the separate responses of its two subpathways – global genomic (GG-NER) and transcription coupled (TC-NER) DNA repair. The pathways converge with the recruitment of the TFIIH complex, a key step that is mediated by the translocase and helicase activities of  its XPD subunit. Germline mutations in XPD result in the clinical disorders, Xeroderma Pigmentosum (XP) and XP combined with Cockayne Syndrome (XP/CS). The goal of this thesis was to understand if XPD XP and XP/CS mutations differentially impact GG-NER and …

Extracellular matrix (ECM) dysregulation plays a significant role in the development of intervertebral disc disease (IVDD). The ECM around the chondrocytes in the nucleus pulposus (NP) is unique in that it contains ColVI. While linked to chondrocyte proliferation in cartilage, ColVI's specific role in IVD degeneration is less clear. Our aim was to determine the expression of ColVI in NP cells from degenerative IVDs, along with the effects of soluble ColVI on NP cells. Thus, we compared the expression levels of ColVI in human degenerated IVD samples, along with the effect of soluble ColVI on primary human NP cells. A …

Dnp Final Report: Improving Length Of Stay Outcomes Using Structured Barrier Rounds: A Quality Improvement Project, Martha Kwamboka Apella

DNP Final Reports

Prolonged length of stay (LOS) in the acute care setting is a challenging issue driven by multiple factors. Increased LOS is associated with mortality, hospital-acquired infections, patient safety events, functional impairment, decreased quality of life, social isolation, and increased cost of care. The causes of increased LOS in the medical-surgical unit are unclear, necessitating an evidence-based project to address the problem. The purpose of this quality improvement initiative was to implement structured interdisciplinary barrier rounds and evaluate their effect on LOS, opportunity days, and estimated cost of care in a medical-surgical unit. The facility complex care coordinator (CCC) was identified …


Simbinder-If: Structure-Aware Antibody Affinity Optimization Via Efficient Preference Learning, Xinyan Zhao, Yi-Ching Tang, Rivaaj Monsia, Victor J Cantu, Ashwin Kumar Ramesh, Siyu Yang, Xiaozhong Liu, Zhiqiang An, Xiaoqian Jiang, Yejin Kim Jul 2026

Simbinder-If: Structure-Aware Antibody Affinity Optimization Via Efficient Preference Learning, Xinyan Zhao, Yi-Ching Tang, Rivaaj Monsia, Victor J Cantu, Ashwin Kumar Ramesh, Siyu Yang, Xiaozhong Liu, Zhiqiang An, Xiaoqian Jiang, Yejin Kim

The Brown Foundation: Institute of Molecular Medicine

Motivation: Antibody therapeutic efficacy depends on high-affinity target engagement, yet laboratory affinity maturation is slow and costly. Most protein language models (PLMs) lack explicit training for high affinity, and current preference optimization methods introduce computational overhead without clear affinity improvements. Therefore, structure-aware and parameter-efficient approaches for antibody affinity optimization are urgently needed.

Results: We propose SimBinder-IF, a structure-aware antibody optimization model trained by freezing the Evolutionary Scale Modeling inverse folding (ESM-IF) structure encoder and fine-tuning only its decoder via Simple Preference Optimization (SimPO) to prefer stronger binders. In generalization tests across seven held-out complexes (93 477 mutants), SimBinder-IF shows a …


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 …

2020-Current year OA Pubs

BACKGROUND: Catheter-associated urinary tract infection (CAUTI) surveillance is critical for patient safety. Many healthcare systems use electronic algorithms to flag candidate infection events but still require manual chart review to confirm CAUTI cases. We evaluated the use of a large language model (LLM) to enhance CAUTI surveillance.

METHODS: We analyzed 919 potential CAUTI cases flagged by the electronic surveillance algorithm at Barnes-Jewish Hospital from 2021 to 2024. These cases were previously classified as 291 CAUTIs and 628 non-CAUTIs by trained infection preventionists (IPs). Several approaches for applying the National Healthcare Safety Network (NHSN) CAUTI definition after extracting clinical data from …

Many neurological diseases impact specific brain regions despite widespread expression of the disease-related protein. Spinocerebellar ataxia type 1 (SCA1) primarily affects the cerebellum, though Ataxin-1 (ATXN1) is widely expressed. We previously showed that intensified interaction between mutant ATXN1 and Capicua (CIC) drives SCA1 pathogenesis in the cerebellum, whereas ATXN1 loss augments amyloid β production in the hippocampus and cortex. CIC, however, forms a complex with ATXN1 and its paralog, Ataxin-1-like (ATXN1L), yet knockout of either yields completely different phenotypes. To determine whether this could be due to CIC having two isoforms, we generated mice bearing either the long (CIC-L) or …

Protein glycosylation is the most prevalent post-translational modification and is known to undergo profound alterations in disease. While serum N-glycosylation has been extensively studied, interstitial fluid is gaining prominence as a minimally invasive biomarker source, underscored by the widespread clinical adoption of wearable glucose monitors in diabetic patients. However, the glycomic landscape of interstitial fluid remains largely unexplored. Here, we have performed a comparative analysis of the N-glycome from interstitial fluid and matched plasma from five healthy volunteers using liquid chromatography, mass spectrometry and exoglycosidase digestions. Strikingly, the interstitial fluid N-glycome closely shows overlapping profiles with the plasma of each …

Epilepsy affects approximately 50 million people worldwide, yet more than half of individuals with a presumed genetic cause still lack a molecular diagnosis despite the identification of over 1,000 monogenic epilepsy genes. This diagnostic gap is unlikely to be resolved by improved variant detection alone, suggesting that variants affecting the same biological pathway may combine to cause disease. By studying epilepsy-associated actin regulatory genes, we identified a conserved "actin-mitochondria-glutamate (AMG) pathway". We demonstrate that reduced actin polymerization promotes DRP1-mediated mitochondrial fission, increases reactive oxygen species (ROS) levels, and enhances glutamatergic transmission, leading to seizures. The glial innate immune pathway, a …
