Identifying tertiary structures and protein binding sites in RNA molecules remains a key challenge in RNA biology. We describe multi-site dimethyl sulfate (DMS)-mutational profiling (MaP) (msDMS-MaP), a strategy that enables simultaneous measurement of RNA secondary, tertiary, and quaternary structures via a single DMS chemical probing experiment. Optimized reverse transcription decodes typically invisible DMS N7-methylguanine (N7-G) modifications via a tautomer-induced mutational signature concurrent with N1 and N3 modifications. We show that N7-G reactivity reports on higher-order RNA structures, revealing key functional motifs such as pseudoknots and protein binding sites. Using msDMS-MaP, we find that E. coli ribosomal RNAs encode numerous independently …

Gut Microbiota Modulation Of Regulatory Dna Elements Revealed By Massively Parallel Functional Characterization, Chadmirah Zaratiana, Adheet Ganesh, Yang E Li, Et Al.

2020-Current year OA Pubs

Cis-regulatory elements (CREs) are central to dynamic gene regulation in hepatocytes, yet most functional annotations derive from in vitro models that poorly capture physiological regulation. We systematically profiled 109,386 human liver-derived CREs using massively parallel reporter assays in hepatocytes under matched in vitro and in vivo conditions. In vivo-active functional CREs (fCREs) were enriched for H3K27ac and chromatin accessibility and were regulated by diverse transcription factors in the human liver. We further demonstrate that gut microbiota-derived signals modulate fCRE activity and target gene expression in vivo, in part via the KEAP1/NFE2L2 antioxidant pathway. Specific microbial metabolites directly altered the activity …

Cellular And Molecular Basis Of Pfcoronin Function In Artemisinin Resistance In Plasmodium Falciparum, Imran Ullah, Eva S Istvan, Et Al.

2020-Current year OA Pubs

Artemisinin combination therapies are central to malaria control, but their efficacy is threatened by the emergence of resistant Plasmodium falciparum strains. While the role of Pfkelch13 mutations is well established, mutations in Pfcoronin have also been implicated in treatment failure, revealing layers of resistance complexity. Here, we define the cellular mechanism of Pfcoronin‑mediated artemisinin resistance. PfCoronin interacts with PfActin and localizes to the parasite plasma membrane, the digestive vacuole membrane, and small vesicles containing host cell material. Mutations in PfCoronin disrupt its localization and perturb PfActin homeostasis, altering the distribution of ring‑stage morphologies, including a reduced proportion of parasites adopting …

Genetic Analysis Of The X-Linked Adrenoleukodystrophy Gene Abcd1 In Drosophila Uncovers A Conserved Phenotype, Joshua Manor, Sharayu V Jangam, Hyung-Lok Chung, Pranjali Bhagwat, Jonathan C Andrews, Hillary Chester, Shu Kondo, Saurabh Srivastav, Juan Botas, Ann B Moser, Suzette M Huguenin, Michael F Wangler

Duncan NRI Faculty and Staff Publications

X-linked adrenoleukodystrophy (X-ALD) is a progressive neurodegenerative disorder caused by a loss-of-function (LOF) mutation in the ATP-binding cassette subfamily D member 1 (ABCD1) gene, leading to the accumulation of very long-chain fatty acids (VLCFAs). This disorder exhibits striking heterogeneity; some male patients develop an early childhood neuroinflammatory demyelination disorder, while other patients, including adult males and most affected female carriers, experience a chronic progressive myelopathy. Adrenocortical failure is observed in almost all male patients, with the age of onset varying, sometimes being the first diagnostic finding. The gene underlying this spectrum of disease encodes an ATP-binding cassette (ABC) transporter that …

Ultra-Rare Functional Variants Reveal Early-Onset Breast Cancer Risk Genes And Pathways In The Uk Biobank And All Of Us Research Program, Jennifer Asmussen, Kevin Wilhelm, Kwanghyuk Lee, Chen Wang, Panagiotis Katsonis, Yi Li, Lawrence A Donehower, Olivier Lichtarge

Faculty, Staff and Students Publications

Breast cancer (BRCA) affects one in eight women, and while past studies have identified susceptibility genes and variants, those driving early-onset disease remain opaque. We introduce EA-Pathways, a control-free association method that aggregates ultra-rare germline coding variants weighted by Evolutionary Action to detect functional impact distribution biases in genes and pathways. In UK Biobank women with BRCA, EA-Pathways prioritized candidate risk genes across pathways enriched in known familial genes. Ultra-rare, high-impact variants in these genes were BRCA specific, and variants from eight pathways were associated with 2-year-earlier disease, including homology-directed DNA repair, TP53, and pexophagy pathways. The early-onset effect replicated …

Mind Over Measure: The Role Of Self-Care Practices In Mitigating Mental Health Strain Among K-12 Educators, Jerry Burkett, Ryan Hulla

School Leadership Review

Teacher mental health is a critical concern in K-12 education, with high rates of burnout demanding effective protective strategies. This study investigated the relationship between five dimensions of teacher self-care (Physical, Psychological, Emotional, Spiritual, and Professional) and overall mental health outcomes, while specifically exploring differences between elementary (K-5) and high school (9-12) educators. A sample of K-12 teachers completed the Mental Health Inventory (MHI-5) and the Self-Care Inventory. Correlational analysis found that all five self-care dimensions were significantly and positively associated with mental health, with Professional Self-Care demonstrating the strongest link (r=.48, p

Screening Novel Secreted Proteins For Their Effects On Pancreatic Islet Function Using Qpcr-Based Gene Expression Analysis, Deepti Agarwal, Neha Mishra, Marcus Seldin

Cumberland Medica

Type 2 diabetes (T2D) involves progressive dysfunction of pancreatic β-cells and systemic insulin resistance. Although a handful of secreted factors acting on pancreatic islet have emerged as important therapeutic targets, many additional signaling processes remain unknown. The identification of such mediators can make a new contribution to the regulation of islet biology and serve as another approach for disease treatment. This study aimed to investigate whether three novel peptides could modulate islet-specific gene expression in vivo. Methods: Male C57BL/6J mice were injected with proteins then pancreatic tissues were collected six hours post-treatment. Total RNA was isolated, converted to cDNA, and …

Involuntary Medication Administration Review: A Historical Look At New Jersey Psychiatric Law And Its Significance, Casey Burke, Joon Min Chun D.O., Ramya Kommidi D.O., Salvatore Montana Messina D.O.

Rowan-Virtua Research Day

The legal and ethical evolution of involuntary psychiatric medication in New Jersey has been shaped through the landmark legal cases Rennie v. Klein and Brandt v. Monte. To this effect, this poster explores how each case shaped state hospital policy and the balance between patient autonomy and clinical judgment. Rennie v. Klein (1978) established a constitutional right for involuntarily committed patients to refuse psychotropic medication, except in emergencies or with due process safeguards. Decades later, Brandt v. Monte (2006) exposed flaws in New Jersey’s administrative procedures—particularly Administrative Bulletin 78-3—which permitted coercive practices under the guise of emergency treatment and lacked …

Understanding The Immune Responses Of Macrophages And Neutrophils In Synovial Fluid And Post-Operative Joint Environments, Allison Noelle Snyder

Rowan-Virtua Research Day

Periprosthetic joint infections (PJI) are devastating complications of total joint replacement (TJA). Even with aggressive antibiotic treatments, PJI recurrence rates are >17%, and 5-year survival is only 87.3%. Understanding the levels of inflammatory markers and cell types present at different timepoints is crucial in maximizing antimicrobial therapy and preventing adverse outcomes following TJA. This study tests the hypothesis that the synovial fluid environment of PJI induces immunosuppression in human macrophages, thereby hindering their ability to kill bacteria.

How Do Adverse Social Determinants Of Health Influence 30-Day Hospital Readmission Rates Among Patients With Heart Failure?, Noor Baig

Rowan-Virtua Research Day

Heart failure is one of the leading causes of hospitalization in the United States, with nearly 1 in 4 patients readmitted within 30 days of discharge. Clinical severity largely accounts for this risk, but social determinants of health (SDOH), including income, housing stability, transportation access, and health literacy, also play a role in post-discharge outcomes. This review synthesized seven cohort, observational, and qualitative studies from PubMed (2018–2025) examining the relationship between SDOH and 30-day readmission in heart failure patients.

Several patterns emerged across the literature. Neighborhood socioeconomic disadvantage, measured through ADI and SDI, was independently associated with higher readmission and …

Premenstrual Disorders In Females With Neurodevelopmental Conditions: A Systematic Review, Akhila Archakam, Nikhila Archakam, Harshal Parmar, Wesley Kim

Rowan-Virtua Research Day

Background: Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are prevalent conditions associated with substantial functional impairment and psychiatric morbidity. Symptoms are driven by heightened sensitivity to cyclical fluctuations in estrogen and progesterone rather than absolute hormone levels. Individuals with neurodevelopmental conditions, particularly attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), may exhibit altered neurobiological and emotional regulation pathways that increase vulnerability to these hormonal changes; however, this relationship has not been systematically synthesized.

Methods: A systematic review was conducted in accordance with PRISMA guidelines. PubMed, Embase, and Cochrane CENTRAL were searched from 2000–2026 for studies evaluating associations between ADHD, …

Evaluating Referral Coordination And Scheduling In Primary Care: A Qualitative Study Of Workflow Gaps, Aprupa Alahari, Philycia Foote, S. Vincent Grasso

Rowan-Virtua Research Day

Background

Healthcare referral workflows remain fragmented despite widespread adoption of electronic health records. Primary care to specialty referrals frequently rely on fax, phone calls, manual scheduling, and disconnected communication systems, creating delays, incomplete referrals, and administrative burden.1,2 Prior literature has identified a lack of referral tracking, referral leakage, and lack of closed-loop communication as major barriers to coordinated care. Altogether, efforts are required to keep cases from falling into the “referral black hole” that plagues health systems.2-4

Hypothesis

We hypothesized that:

1. there is substantial patient burden

2. there is substantial operational fragmentation

3. current referral systems contain limited visibility or verification

What Is The Role Of The Gut Microbiome In Modulating Immune Tolerance And The Development Of Allergic Disease In Infants?, Priyal Gajera

Rowan-Virtua Research Day

Introduction: The infant gut microbiome plays a critical role in immune system development during the early-life “window of immune education.”¹ Microbial colonization influences immune tolerance through mechanisms such as regulatory T-cell (Treg) induction, short-chain fatty acid (SCFA) production, and mucosal immune regulation. Disruptions in this process (dysbiosis) are associated with increased risk of allergic diseases, including food allergy, atopic dermatitis, and asthma. Environmental and maternal factors such as delivery mode, antibiotic exposure, and feeding practices significantly impact microbial composition and immune outcomes.²

Methods: A literature review was conducted using PubMed with search terms related to the gut microbiome, …

Effect Of Parkinson’S Disease On The Lateralization Of The Digastric Muscle In A Rodent Model, Estelle Richardson, Francois Gould

Rowan-Virtua Research Day

In Parkinson’s disease, the loss of dopaminergic neurons in the substantia nigra can cause dysphagia, which affects all phases of swallowing. In swallowing, bilateral pairs of muscles under the control of independent unilateral neural mechanisms must simultaneously activate to coordinate their movements and produce a swallow. However it is unknown how Parkinson’s disease impairs the activation of the right and left sides of those muscles. In this study we tested how Parkinson’s disease impacts the lateralization of the digastric muscle in rats. We hypothesized that Parkinson’s disease will cause a difference in activation of the right and left digastric muscles …
