2020-Current year OA Pubs

BACKGROUND: Gardnerella is a bacterial genera commonly present in the female urogenital tract, especially in bacterial vaginosis. Gardnerella are frequently detected in urine collected directly from the bladder and have been implicated in urinary incontinence and recurrent urinary tract infections. Understanding the contribution of Gardnerella to pathogenesis is complicated by its genetic heterogeneity and a shortage of data from in vivo models. One clinical isolate of Gardnerella triggered urothelial exfoliation and promoted urinary tract infection by uropathogenic E. coli in a mouse model. This study was designed to compare diverse Gardnerella strains in vivo to identify genomic variation associated with …

Improving Lunch Break To Enhance Nurse Happiness And Job Satisfaction, Evelyn O. Dumkwu Feb 2026

Improving Lunch Break To Enhance Nurse Happiness And Job Satisfaction, Evelyn O. Dumkwu

Doctor of Nursing Practice Projects

Nurses frequently forgo scheduled lunch breaks due to high workload demands, inadequate staffing, and organizational cultures. Consistently skipping breaks has been associated with reduced happiness and lower job satisfaction, which may ultimately compromise the quality of patient care. This quality improvement (QI) project examined whether the structured observance of scheduled lunch breaks enhances nurses’ subjective happiness and job satisfaction. Guided by Lewin’s Change Theory and the Donabedian Theoretical Framework and implemented using the Plan–Do–Study–Act (PDSA) framework, the project employed a quasi-experimental pre–post design during a six-week implementation period. Ten full-time nurses participated in the project. Investigator-designed Subjective Happiness and Job …

This study examined whom college-aged individuals believe observing would more likely increase their physical activity self-efficacy (PASE) for a physical skill, whom they are more likely to compare their abilities to within a physical education (PE) class, how often they compare themselves to others in PE, and what students’ PASE scores were. Based on the mean scores for each question, students were more likely to compare themselves to a student than a teacher, friend than a non-friend, and similar or higher skilled peer than a lower skilled peer. To increase students’ confidence for a physical skill, students had higher levels …


Steroid Receptor Coactivators - From Basic Research To Translational Opportunities, Yosef Gilad, Sang Jun Han, David M Lonard Feb 2026

Steroid Receptor Coactivators - From Basic Research To Translational Opportunities, Yosef Gilad, Sang Jun Han, David M Lonard

Faculty, Staff and Students Publications

The concept of nuclear receptor (NR) coregulation was proposed nearly two decades before it was experimentally validated. According to this model, NRs - executors of a vast array of transcriptional programs - do not act independently but are governed by a network of regulatory proteins that either activate or repress their biological function. NRs identify the genes to be regulated. However, coregulators ultimately serve as the true controllers of transcriptional outcomes. They recruit cofactors and coordinate the activity of transcriptional complexes, thereby shaping NR-mediated gene expression beyond NRs' intrinsic functionality. The Steroid Receptor Coactivator (SRC) family is the most extensively …

The Brown Foundation: Institute of Molecular Medicine

Microglia critically shape neuronal circuit development and function, yet their region-specific properties and roles in distinct circuits of the human brain remain poorly understood. In this study, we generated region-specific brain organoids (cortical, striatal, and midbrain), each integrated with human microglia, to fill this critical gap. Single-cell RNA sequencing uncovered six distinct microglial subtypes exhibiting unique regional signatures, including a subtype highly enriched for the GABAB receptor gene within striatal organoids. To investigate the contributions of microglia to neural circuitry, we created microglia-incorporated midbrain-striatal assembloids, modeling a core circuit node for many neuropsychiatric disorders, including autism. Using chemogenetics to activate …

Association Between Children’S Secondhand Co-Exposure To Tobacco And Cannabis Smoke And Elevated Urinary Cotinine Levels: A Cross-Sectional Analysis, Bradley N. Collins, Stephen J. Lepore, Vincent Berardi, Renee D. Goodwin, Karen Wilson, Mona Baishya

Psychology Faculty Articles and Research

Background Cannabis use is far more common among adults who smoke tobacco than adults who do not, and its use is increasing among people who smoke tobacco with children living in the home. Given the well-established evidence that caregiver smoking is the primary source of children’s secondhand exposures to these products, the increasing trend in caregiver co-use is raising public health concerns about children’s co-exposure. Emerging data indicates that adult co-use is linked to additive health consequences, such as elevated nicotine and other tobacco-related toxicant blood levels, relative to use of only tobacco. It is unknown whether children’s co-exposure leads …

Department of Pediatrics Faculty Papers

INTRODUCTION: The I-PASS handoff tool guides provider handoffs and reduces adverse events in the inpatient setting. Transitions of care occur frequently in the emergency department (ED), and the unpredictable environment can lead to less structured handoffs. Our goal was to increase the percentage of handoff notes that include all 4 I-PASS components by 20% within 6 months.

METHODS: We developed a handoff note template for the pediatric ED that included 4 key I-PASS elements: illness severity, patient care summary, action list, and situational awareness/contingency planning. Our primary outcome measure was the percentage of handoff notes that contained all 4 I-PASS …

Although BRAF/MEK inhibitor (BRAFi/MEKi) therapy initially shows high efficacy in patients with BRAFV600 E/K cutaneous melanoma, resistance develops in over 75% of cases. We tested robustness of the umbrella trial strategy in this population by analyzing relationships between genomic status of a gene and associated downstream consequences at the protein level. The results revealed weak relationships among mutations, copy-number amplification, and protein expression and activation. An in vivo compound repurposing screen using 11 clinically relevant agents from an NCI-portfolio with pan-RTK, non-RTK, and/or PI3K-mTOR specificity identified dasatinib as most capable of restoring sensitivity to BRAFi/MEKi in patient-derived xenograft (PDX) …

Efficient DNA double-strand break (DSB) repair by homologous recombination (HR), as initiated by BRCA1 recruitment orchestrated by histone and non-histone proteins, is critical to genome stability, replication, transcription, and cancer avoidance. Here we reveal Heterochromatin Protein1 beta (HP1β) promotes BRCA1 enrichment at DNA DSB sites in gene-rich regions, and this is impaired by HP1β depletion. We find that HP1β is specifically enriched at DSBs within gene-rich regions via its Chromo Shadow Domain (CSD) that interacts with both Chromatin Assembly Factor 1 and the RING1A ubiquitinase component of Polycomb Repressor Complex 1. The resulting protein complex facilitates BRCA1 recruitment by promoting …

Genetic Modifiers Of Apoe-Ε4-Associated Cognitive Decline, Alex G Contreras, Carlos Cruchaga, Et Al.

2020-Current year OA Pubs

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease. However, APOE-ε4 is not deterministic, highlighting the need to identify additional genetic and environmental factors. APOE-ε4 has been linked to accelerated cognitive decline, so we sought to investigate genetic factors that modify APOE-ε4-associated cognitive decline. We conduct cross-ancestry APOE-ε4-stratified and interaction GWAS using harmonized cognitive data from 32,778 participants, including 29,354 non-Hispanic White and 3,424 non-Hispanic Black individuals. Our primary outcome is late-life cognition, measured using harmonized composite scores for memory, executive function, and language, modeled as continuous traits reflecting both normative cognitive aging and disease-related decline. …

Disruption Of Proteoglycan 4 (Prg4)-Cd44 Signaling Modulates Chronic Synovitis In Conditionally Inactivated Mice, Khaled A. Elsaid, Ling Zhang, Thomas Zhao, Ava Marks, Derek Jenkins, Gregory D. Jay

Pharmacy Faculty Articles and Research

Background

Proteoglycan-4 (PRG4) is a mucinous glycoprotein secreted by synovial fibroblasts and superficial zone chondrocytes. PRG4 inhibits synovial macrophage (SM) activation via xanthine oxidase (XO) and hypoxia inducible factor alpha (HIF-1α) suppression. We aimed to evaluate the contribution of PRG4-CD44 interaction to synovial homeostasis and investigate PRG4’s signaling dysfunction in synovial tissues from patients with osteoarthritis (OA). We hypothesized that CD44 mediates synovitis due to PRG4 loss and that PRG4 signaling dysfunction is associated with high-grade synovitis in OA.

Methods

Prg4FrtloxP/FrtloxP are transgenic mice wherein tamoxifen (TAM) inactivates the Frt allele and creates a knockout state (Prg4FrtKO/FrtKO …

The Neuroprotective Effects Of Alpha-Tocopherol As An Anti-Inflammatory Agent: Mechanistic Insights And Therapeutic Challenges, Megumi H Seese, Yuanzhong Xu Feb 2026

The Neuroprotective Effects Of Alpha-Tocopherol As An Anti-Inflammatory Agent: Mechanistic Insights And Therapeutic Challenges, Megumi H Seese, Yuanzhong Xu

The Brown Foundation: Institute of Molecular Medicine

Vitamin E (alpha-tocopherol, αToc), an antioxidant fat-soluble vitamin that prevents lipid peroxidation and modulates pro-inflammatory cytokine production, is well-known to be critical for neuroprotection. However, the underlying mechanism remains poorly understood. Accumulating evidence demonstrates that αToc influences neuroinflammatory processes. Here, we review recent research progress on the effects of αToc on neuroinflammation. Preclinical studies included in this narrative review were identified through PubMed searches using the keywords "alpha-tocopherol AND neuroinflammation or alpha-tocopherol AND brain AND inflammation". While many studies support a neuroprotective role of αToc, the magnitude and direction of its effects vary substantially depending on dosage, route of administration, …

At the foundation of neurotransmission, and by extension at the foundation of brain function, are coordinated programs of gene expression involving many thousands of genes. These programs are poorly defined in humans because most modern studies that characterize human brain gene expression use tissue obtained in the postmortem state when neurotransmission and brain function have ceased. Here, to advance knowledge of the gene expression programs at the foundation of neurotransmission in the human brain, gene expression was characterized in 130 prefrontal cortex (PFC) samples obtained from participants of the Living Brain Project (LBP) during neurosurgical procedures in conjunction with intracranial …
