RAD52 is a conserved member of the homologous recombination repair (HRR) apparatus from yeast to humans. Mutating conserved amino acids in the internal and external DNA binding domains of the human RAD52 protein (HsRAD52) has discrete effects in vitro. Previous studies have shown that HsRAD52 supports multiple mechanisms of HRR in budding yeast, suggesting the utility of this model system for exploring the correspondence between losses of HsRAD52 function in vitro and their impact in vivo. We report that disrupting the internal and external DNA binding domains of HsRAD52 produced distinct effects on the repair of genomic DNA double-strand breaks …

Dysregulated ribosome biogenesis and p53 mutations are known to play oncogenic roles in various cancers, including pancreatic cancer. In this study, we demonstrated the therapeutic potential of BMH-21, a pharmacologic inhibitor of RNA polymerase I, against pancreatic cancer by uncovering a novel molecular mechanism involving RPA194-mediated ubiquitination of mutant p53 without affecting the ubiquitination of wild-type p53. Our key findings are that (i) BMH-21 selectively induces apoptosis and cell growth inhibition of pancreatic cancer cells with no effect on normal human pancreatic ductal epithelial cells; (ii) BMH-21 degrades RPA194; (iii) BMH-21 inhibits recruitment of both RPA194 and RPA135 on rDNA …


The Next Layer: Augmenting Foundation Models With Structure-Preserving And Attention-Guided Learning For Local Patches To Global Context Awareness In Computational Pathology, Muhammad Waqas, Rukhmini Bandyopadhyay, Eman Showkatian, Amgad Muneer, Anas Zafar, Frank R Alvarez, Maricel Corredor Marin, Wentao Li, David Jaffray, Cara Haymaker, John V Heymach, Natalie Vokes, Luisa M Solis Soto, Jianjun Zhang, Jia Wu Feb 2026

Foundation models have emerged as powerful feature extractors in computational pathology. However, they typically omit mechanisms for leveraging the global spatial structure of tissues and the local contextual relationships among diagnostically relevant regions-key elements for understanding the tumor microenvironment. Multiple instance learning (MIL) remains an essential next step following the foundation model, designing a framework to aggregate patch-level features into slide-level predictions. We present EAGLE-Net, a structure-preserving, attention-guided MIL architecture designed to augment prediction and interpretability. EAGLE-Net integrates multi-scale absolute spatial encoding to capture global tissue architecture, a top-K neighborhood-aware loss to focus attention on local microenvironments, and background suppression …

Radiation therapy is integral to the treatment regimens of over 50% of cancer patients. However, it is not biologically targeted to just the tumor, leading to adverse effects in peritumoral normal tissue. Selective uptake of gold nanoparticles (AuNPs) by tumors realizes tumor-specific radiosensitization via increased secondary electron release from high atomic number gold atoms. Here, we review AuNP-mediated radiosensitization and outline strategies to optimize tumor-targeted AuNP delivery. Modifying the physicochemical characteristics of AuNPs, including size, shape, charge, and surface chemistry, can increase their ability to evade the reticuloendothelial system (RES) and penetrate the dense tumor stromal architecture, thereby promoting tumor …

Background: Stroke is a sexually dimorphic disease, with different risk factors, incidence, outcomes, and treatment responses in men and women. While sex differences have been documented in preclinical studies, these findings often come from single-site studies with small sample sizes and require validation across diverse research settings.

Methods: We used data from the SPAN (Stroke Preclinical Assessment Network), a randomized, placebo-controlled, blinded, multilaboratory trial, to determine if sex differences in neurological outcomes are present in preclinical stroke models. We analyzed data from 665 stroke animals treated with saline, including young mice, diet-induced obese mice, aging mice, young rats, and spontaneously …

Purpose: Airway hyperresponsiveness in asthma is driven by acetylcholine-mediated activation of the muscarinic acetylcholine 3 receptor (M3R), promoting bronchoconstriction, mucus hypersecretion, and airway remodeling. Despite directly targeting this pathway, antimuscarinics remain adjunctive rather than first-line therapy, suggesting a disconnect between biological rationale and clinical efficacy. Recent work from the Scott Lab at Thomas Jefferson University demonstrates that M3R in human airway smooth muscle (HASM) cells drives muscle shortening through G12/13–driven RhoA signaling rather than through Gq/11-dependent calcium flux. We therefore investigated whether clinically prescribed antimuscarinics effectively inhibit G12/13-dependent RhoA signaling in HASM cells.

Biologically-Inspired Multiscale Neuromorphic Architecture, Christian O'Reilly, Ramtin Zand Feb 2026

Biologically-Inspired Multiscale Neuromorphic Architecture, Christian O'Reilly, Ramtin Zand

Publications

This white paper proposes a biologically-inspired multiscale neuromorphic architecture that bridges key gaps between artificial neural networks (ANNs), spiking neural networks (SNNs), and biological neural networks (BNNs). While SNNs offer promising energy efficiency, their broader adoption remains limited by suboptimal performance and the need for novel learning paradigms. To address these challenges, the proposed framework integrates structural and functional principles observed in the brain, including hierarchical organization, sparse and modular connectivity, predictive coding, and diverse neuronal dynamics.

The architecture operates across micro-, meso-, and macro-scales, incorporating neuron-level diversity (e.g., excitatory/inhibitory and principal/support cells), canonical microcircuits (CMCs), and large-scale hierarchical organization. …

The role of the tumor immune microenvironment (TIME) in modulating responses to antiestrogen therapy in hormone receptor-positive (HR+) breast cancers remains unclear. We analyzed pre- and on-treatment biopsies from patients with HR+ breast cancer treated with letrozole to induce estrogen deprivation (ED). Stromal tumor-infiltrating lymphocytes, assessed by H&E staining, and immune-related gene sets, including IFN-γ signaling genes, measured by RNA-Seq, were increased in ED-resistant tumors. Cyclic immunofluorescence and spatial transcriptomics revealed an abundance of CD8+ T cells and enhanced antigen processing and immune gene signatures in ED-resistant tumors. In this group, the expression of CXCL9, CXCL10, and CXCL11 - chemokine …

EGFR-mutant lung adenocarcinomas (LUADs) that are vulnerable to the EGFR antagonist osimertinib (Osi) eventually relapse, owing in part to the emergence of drug-tolerant persister (DTP) cells that arise through epigenetic mechanisms. Intratumoral DTP cells can herald a worse clinical outcome, but the way in which DTP cells influence LUAD progression remains unclear. Osi-resistant (OR) cells exhibit typical DTP cell features, including a propensity to undergo senescence and epithelial-mesenchymal transition (EMT), which can activate heightened secretory states. Therefore, we postulated that OR cells influence LUAD progression through paracrine mechanisms. To test this hypothesis, we utilized congenic pairs of EGFR-mutant LUAD cell …

The development of structurally distinct and modular photocatalysts for direct hydrogen atom transfer (HAT) has emerged as a key frontier in radical-mediated C-H functionalization of strong carbon-hydrogen bonds. Despite the largely untapped potential across the fields of organic synthesis, medicinal chemistry, and materials science, few classes of direct HAT photocatalysts are currently known, and the approaches to enhancing their photocatalytic activity remain underdeveloped. We report herein the development of nitrogen-centered direct HAT photocatalysts based on the acridine framework, which leverage a C9-ortho-biaryl substituent for enhancing the photocatalytic activity through stabilizing dispersion interactions with the substrate as the key steering effect. …

The molecular pathways linking genetic variants to Parkinson's disease (PD) onset and progression remain incompletely defined; however, risk alleles in multiple genes, including GBA1, strongly implicate lipid metabolism. To systematically identify causal biomarker signatures, we analyzed comprehensive metabolome profiles from blood plasma in 149 PD patients and 150 controls, along with complementary genetic, RNA-sequencing, and metabolic data from other available clinical and pathologic cohorts. Using colocalization and summary-data-based Mendelian randomization, we tested whether expression and metabolic quantitative trait loci mediate the association between implicated genetic variants and PD risk. We further integrated differential metabolomics and proteomics from blood and brain …

Non-tuberculous mycobacteria (NTM) are common environmental pathogens, but they are an uncommon cause of illness. One such mycobacteria, Mycobacterium shimoidei, was discovered in 1968 and found to cause a respiratory illness in 1975. Since then, fewer than 100 cases have been reported worldwide. Symptoms can include cough, fever, weight loss, and hemoptysis This report describes an American patient with no travel history who was found to have significant pulmonary disease caused by this rare non-tuberculous mycobacteria.


Engineering Enac Constructs To Examine Pip2 And Ubiquitin Competition On Enac Regulation And Stability, Lacie Johnson Feb 2026

Engineering Enac Constructs To Examine Pip2 And Ubiquitin Competition On Enac Regulation And Stability, Lacie Johnson

Chemistry & Biochemistry Undergraduate Honors Theses

The epithelial sodium channel (ENaC) plays a critical role in sodium homeostasis, fluid balance, and blood pressure regulation. ENaC activity is tightly controlled by post-translational mechanisms, including ubiquitination-mediated degradation and phosphatidylinositol 4,5-bisphosphate (PIP2) dependent channel activation. PIP2 is a phospholipid necessary to facilitate the maximal channel opening. Previous studies suggest that intracellular PIP2 binding sites are located in proximity to ubiquitination sites on ENaC subunits, raising the possibility of PIP2 binding to influence channel stability and function. This thesis aimed to engineer and validate molecular tools capable of examining the interplay between PIP2 binding and ubiquitination in ENaC regulation. A …

Key Points:

  1. Cardiovascular-kidney-metabolic (CKM) is a global public health problem; however, its mediators remain poorly known, in part due to the lack of a reliable animal model.

  2. A combination of high fat and adenine diet recapitulate some of the CKD and metabolic phenotypes of CKM.

  3. This model also demonstrates myocardial fibrosis and peripheral artery disease with sex-based differences and can be leveraged to probe mechanisms of CKM.

Background: Cardiovascular-kidney-metabolic (CKM) syndrome is a public health problem in the United States and results in premature cardiovascular disease at a relatively preserved GFR. The molecular mediators of CKM are poorly understood, partly …

Objective: Pair-feeding is a study design element where one group's food intake is provided to another group to assess whether a treatment effect is independent of food intake. Investigators often assume equivalent food intake across experimental conditions and exclude it from the statistical analysis. However, the impact of this practice on type I error (T1Er) rates has not been quantified.

Methods: We conducted a Monte Carlo simulation in which animals were assigned baseline weights and food intakes, then randomized to non-pair-fed or pair-fed groups. Daily food intake for both groups was initially drawn from the baseline food intake distribution. For …

Objectives: Candida species are one of the most common causes of ICU-onset bloodstream infection (BSI). Yet, there is no robust guidance on when to initiate empiric antifungals for ICU patients suspected of BSI. We compared patients with ICU-onset candidemia vs. ICU-onset bacteremia to determine which patients may benefit from empiric antifungals.

Design: We compared characteristics between patients with bacteremia vs. candidemia at time of culture. We determined risk factors for death and constructed a multivariable regression to determine if candidemia is an independent risk factor for death.

Setting/patients: We included ICU patients from a hospital system in Houston, Texas (n …

C1INH (C1-inhibitor) is a multifunctional SERPIN (serine protease inhibitor) that functions as a major negative regulator of the complement, coagulation, and kallikrein-kinin systems. C1INH products were originally developed for the treatment of hereditary angioedema associated with C1INH deficiency. A growing body of literature indicates that C1INH products may find utility in the management of several other disease states. In this review, we detail the key biological activities of C1INH and consider the pathophysiological role of C1INH targets in many conditions.

Objective: To establish a framework for validating candidate biomarkers of cerebral small vessel diseases (SVD) associated with cognitive impairment and characterize individuals enrolled by the MarkVCID2 consortium under this framework.

Methods: Participants age 60 to 90 years were enrolled across 17 MarkVCID2 sites. Recruitment was targeted to enrich in cognitive symptoms (mild dementia, mild cognitive impairment, subjective cognitive decline), defined risk factors (diabetes mellitus, advanced hypertension), and Black/African American, White, and Hispanic/Latino subgroups. Enrolled participants underwent baseline visits that included cognitive testing, multimodal magnetic resonance imaging (MRI), and biofluid collection. Provisional risk for SVD-related cognitive decline was estimated primarily by …

Human fatty acid binding protein‐4 (FABP‐4), a protein elevated in obesity that promotes colon cancer cell invasiveness and metastasis, may be associated with higher mortality in individuals with colorectal cancer (CRC) and may serve as a mediator of the obesity–mortality association in these individuals. We used a causal diagram to inform covariate selection and applied Cox proportional hazards models to estimate hazard ratios (HRs) for CRC‐specific, non‐CRC‐specific, and all‐cause mortality by FABP‐4 levels measured in baseline blood samples from 1371 incident CRC cases from the European Prospective Investigation into Cancer and Nutrition cohort. Competing risk analyses were adapted for CRC …

Background: Late radiation-associated dysphagia (late-RAD) commonly presents in patients with signs of hypoglossal neuropathy, with hallmark clinical features including lingual atrophy, deviation, and fasciculation. Gold-standard electromyography (EMG) has not been used to explore the frequency of hypoglossal neuropathy in patients with late-RAD.

Methods: Exploratory post hoc secondary analysis of MANTLE trial (NCT03612531) was completed. The presence of cranial nerve XII (CN XII) neuropathy was classified by (1) features of clinical assessment as well as (2) intramuscular genioglossus EMG pre-MANTLE intervention in disease-free HNC survivors ≥ 2 years post-radiotherapy (RT) with grade ≥ 2 fibrosis and dysphagia.

Results: All …

Importance: Historical evidence demonstrated that delays or interruptions in radiotherapy (RT) are associated with poorer oncologic outcomes in head and neck squamous cell carcinoma (HNSCC). Substantial concerns arose during the COVID-19 pandemic, when treatment schedules were frequently disrupted.

Objective: To determine the association of RT interruptions with locoregional failure (LRF) and overall survival (OS).

Design, setting, and participants: This retrospective review and secondary analysis of 3 randomized clinical trials (NRG/RTOG 0129, 0522, and 1016) included patients enrolled in the trials who were treated with RT. Patients with HNSCC were grouped as (1) p16-positive oropharynx (p16+ OPSCC) and (2) p16-negative oropharynx …
