Breaking Into Hiv-1'S Epigenetic Vault: Cure Strategies To Eliminate The Viral Reservoir, Joanna Jones, Chelsea Gunderson, Brian Wigdahl, Michael Nonnemacher

Kimmel Cancer Center Faculty Papers

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that integrates into the host cell's DNA as a provirus. Transcription from the provirus is regulated in large part by cellular proteins and epigenetic factors. These may be repressive or permissive to productive infection. The host factors that regulate this balance are therefore attractive targets for HIV-1 therapeutics. Indeed, proviral chromatin is the focus of two of the current HIV-1 cure strategies. "Shock and Kill" uses latency reversal agents to open the provirus's chromatin, promoting high levels of gene expression that induce the killing of infected cells. "Block and Lock" uses …

Staff Education To Improve Nurse Confidence In Managing Co-Occurring Conditions, Gloria Johnston

Walden Dissertations and Doctoral Studies

This Doctor of Nursing Practice (DNP) staff education project addressed a lack of confidence and training for nursing staff who care for patients with co-occurring substance use and mental health disorders. The practice problem identified at the local project site was the inconsistent care of this patient population. Addressing this gap was essential because inadequate training can reduce care quality among patients with co-occurring conditions. The practice-focused question for this project was: In nursing staff caring for patients with co-occurring mental health and substance use disorders, how does an evidence-based staff education program on integrated treatment approaches compare to standard …

Pan-Cancer Evolution Signatures Link Clonal Expansion To Dynamic Changes In The Tumor Immune Microenvironment, Xinyu Yang, Wei Liu, Geoff Macintyre, Peter Van Loo, Florian Markowetz, Peter Bailey, Ke Yuan

Faculty, Staff and Student Publications

Cancer is an evolutionary process characterized by profound intratumor heterogeneity (ITH), which can be quantified using in silico estimates of cancer cell fractions (CCFs) of tumor-specific somatic mutations. We demonstrate a data-driven approach based on CCF distributions to identify 4 robust pan-cancer evolutionary signatures from 4,146 tumors across 17 cancer types in The Cancer Genome Atlas (TCGA). These signatures define a continuum of cancer cell fractions reflecting neutral evolution, clonal expansion, and clonal fixation. Correlating evolutionary signatures with mutational and biological programs reveals that tumors enriched for clonal expansion and fixation are associated with immune evasion and distinct changes in …

Cutaneous Rosai-Dorfman Disease Misdiagnosed As Granulomatous Dermatitis: A Diagnostic Pitfall, Sri Naidnur, Jamie Hedrick, Smaran Marupudi, Kara Asbury, Kelly Maedo, Bryan Gammon, Rick Lin

School of Medicine Publications

Cutaneous Rosai-Dorfman disease (CRDD) is an uncommon non-Langerhans cell histiocytosis that may occur without systemic involvement and lacks specific clinical features. We report a 17-year-old female with a slowly enlarging chest lesion initially diagnosed as granulomatous dermatitis on a 4-mm punch biopsy. The lesion was treated as an inflammatory process without improvement. Complete excision revealed a multinodular dermal and subcutaneous infiltrate of large histiocytes demonstrating emperipolesis, confirming CRDD. Systemic evaluation was negative. The initial limited biopsy did not capture defining features, delaying diagnosis.

Persistent nodular lesions that fail to respond to therapy should prompt reconsideration and more representative tissue sampling. …

Mechanism-Informed Transition From Pediatric To Adult Care In Sickle Cell Disease: A Case Study, Jane S Hankins, Tarun Aurora, Rachel Matsumoto, Sara Malone, Ana A Baumann

2020-Current year OA Pubs

BACKGROUND: Healthcare transition (HCT) refers to the shift from a child-centered to an adult-centered model of care, a process that, when well-functioning, can reduce disengagement and improve satisfaction with care. The Six Core Elements (6CE) framework structures HCT services; however, its implementation process remains understudied, limiting its broader applicability. Learning how to effectively implement the 6CE strategies can enhance their application in real clinical contexts. This case study describes the successful implementation of a 6CE-informed transition program for adolescents and young adults with sickle cell disease (SCD), a genetic condition associated with reduced life expectancy. We also propose a mechanism-informed …

Aging is a major risk factor for heart failure, yet the molecular mechanisms linking cardiac aging to the inflammatory pathophysiology of heart failure remain elusive. Mitochondrial dysfunction and defective organelle quality control are emerging hallmarks of the aging heart, but their biochemical underpinnings are poorly defined. Using comprehensive glycomics, we found that cardiac mitochondria from physiologically aged mice (≥ 20 months) are the major intracellular reservoirs of advanced glycation end products (AGEs), derived primarily from the chemical attack of some α-oxoaldehydes on proteins. This was associated with mild mitochondrial dysfunction and structural remodeling. Lysosomes in aged hearts were enlarged, more …

Agha, Mohammed A. Abdalqader, Abdullah Asad Siddiqui, Shafiq Aazmi, Jantson Hoh, Oh Chin Kin Michelle, Sabaa M. Agha, Amjad Abdulhadi Mohammed, Muneer Mohammed Saleh Alsayadi

AUIQ Complementary Biological System

Chronic inflammatory and degenerative disorders are driven by interconnected immune dysregulation, metabolic instability, epithelial barrier disruption, and impaired tissue repair, limiting the durability of conventional single-target therapies. The global rise in chronic inflammatory, metabolic, and age-related degenerative diseases underscores an urgent need for multi-dimensional therapeutic strategies that move beyond isolated molecular targets. Despite rapid advances in microbiome science and regenerative medicine, these fields have largely evolved in parallel, with limited integration at the translational level. Emerging evidence identifies the gut microbiome as a central regulator of systemic immunometabolic homeostasis through microbial metabolites, barrier integrity modulation, and immune-cell education. In parallel, …

Associational Inference With Many Potential Covariates: Bayesian Information Criterion Elastic Net, Farideh Bagherzadeh Khiabani, I-Chan Huang, Jose Miguel Martinez Martinez, Shizue Izumi, Sedigheh Mirzaei, Tiange Zheng, Irina Dinu, Yutaka Yasui

COBRA Preprint Series

Background: An emerging feature in modern biomedical research is collecting and analyzing numerous variables. In the presence of many potential covariates, inference becomes challenging requiring both distinguishing a set of covariates truly associated with an outcome and estimating their corresponding regression coefficients consistently. Traditional statistical inference typically focuses on estimating coefficients assuming a pre-specified set of covariates. Further, advanced machine/statistical learning methods performing both selection and estimation predominantly focus on outcome prediction rather than association inference.

Methods: Motivated by our epidemiological research on long-term childhood cancer survivors, where we aimed to investigate associations between a large pool of longitudinal symptom …

2020-Current year OA Pubs

An early event after lung injury is extracellular matrix (ECM) remodeling and the formation of a provisional matrix. While megakaryocytes and platelets (Mgk/plt) play important roles in hemostasis, their impact on the matrix in lung injury is not fully understood. Using lung intravital microscopy, 3D large area scanning with multiphoton confocal hybrid imaging, and label-free quantitative proteomics, the matricellular protein thrombospondin-1 (TSP1) arising from Mgk/plt protects the lung from alveolar injury. Mgk/plt cell-specific Thbs1 knockout (cKO) mice show increased alveolar barrier disruption with exaggerated neutrophil-mediated injury. The cKO mice exhibit striking extracellular matrix re-organization with reduction in basement membrane matrix …

Good Judgment In Action: Enhancing Surgeon Feedback Through Simulation, Spencer Wilhelm, Jacob Applegarth, Nathan Novotny, Ngan Nguyen

Conference Presentation Abstracts

Introduction: Effective intraoperative feedback is a cornerstone of surgical training, but remains inconsistently delivered. Surgeons who never received structured feedback during their own training lack the tools to deliver it effectively. At our institution, low faculty engagement scores on an Accreditation Council for Graduate Medical Education (ACGME) survey prompted a residency-wide needs assessment, which revealed that most attendings provide feedback perceived by residents as ineffective. To address this, we developed a simulation-based faculty development program grounded in the “Debriefing with Good Judgment” model. Our study aims to evaluate whether this structured intervention can improve the quality and consistency of feedback …

Mist: A Hierarchical Bayesian Framework For Detecting Differential Dna Methylation Dynamics In Single-Cell Data, Daoyu Duan, Wenjing Ma, Wen Tang, Hao Wu, Liangliang Zhang, Hao Feng

Faculty, Staff and Student Publications

Recent advancements in single-cell DNA methylation (scDNAm) sequencing technologies have enabled the profiling of epigenetic landscapes at unprecedented resolution, offering insights into cellular heterogeneity, differentiation and evolution. Trajectory inference, which orders cells along pseudotime, allows researchers to track genomics changes across continuous cell states and identify key loci exhibiting differential methylation. However, no methods currently exist to model methylation changes along pseudotime in scDNAm data. Here, we present a hierarchical Bayesian framework for scDNAm data analysis. Our method, named mist (methylation inference for single-cell along trajectory), models stage-specific biological variations, identifies genomic features with significant methylation changes along pseudotime, and …

Soluble Urokinase-Type Plasminogen Activator Receptor (Supar) As A Biomarker Of Neurodysfunction, Victoria Linden De Rezende, Khiany Mathias, Lucineia Gainski Danielski, Tatiana Barichello, Fabricia Petronilho

Faculty, Staff and Student Publications

The inflammatory response is essential for host defense, but its persistence can lead to chronic systemic inflammation (CSI). Soluble urokinase-type plasminogen activator receptor (suPAR) has emerged as a reliable biomarker of CSI because elevated levels consistently indicate the presence and progression of chronic disease as well as increased mortality risk. There is growing evidence that CSI influences neurovascular regulation, including changes in blood-brain barrier (BBB) integrity, which suggests that suPAR may also be relevant to central nervous system (CNS) processes. This narrative review summarizes current findings on suPAR in CSI and examines its emerging implications for CNS. Higher suPAR concentrations …

Pkmζ-Kibra Interactions, Molecular Turnover, And Memory, Changchi Hsieh, David A Cano, Panayiotis Tsokas, James E Cottrell, André Antonio Fenton, Harel Shouval, Todd Charlton Sacktor

Faculty, Staff and Student Publications

How can the molecules that strengthen synaptic connections maintain memory in the face of molecular turnover? Our previous work showed that persistent interaction between the postsynaptic scaffolding protein, KIBRA, and the autonomously active PKC isoform, PKMζ, is crucial for maintaining synaptic long-term potentiation (LTP) and memory lasting at least a month. This duration is longer than the lifespans of individual KIBRA and PKMζ molecules. Biophysical modeling of the interaction suggests oligomers of KIBRA-PKMζ dimers, but not individual dimers or monomers, can overcome molecular turnover by continuously incorporating newly synthesized KIBRA and PKMζ, replacing those that have degraded. Here we used …
