Mantle cell lymphoma (MCL) is an incurable subtype of B-cell non-Hodgkin lymphoma. Despite multiple approved Bruton tyrosine kinase inhibitors (BTKis), resistance to BTKi continues to pose a major clinical challenge. The transcription factor sex determining region Y-box 11 (SOX11) is expressed in most patients with MCL and is associated with poor outcomes. We have previously demonstrated SOX11-dependent B-cell receptor (BCR) signaling in transgenic models of MCL. Here, we report that SOX11 drives BCR signaling via the transcriptional activation of the PAX5/CD19 axis. The translational potential of these results is significant as single-cell RNA sequencing data show that SOX11 is overexpressed …

Perinatal T cells have distinctive phenotypes and functions that may be due in part to age-associated features of stromal cells in the perinatal thymus. We identify age-associated changes in mouse thymic epithelial cells, mesenchyme, endothelium, and hematopoietic antigen-presenting cells from birth to one month of age using single-cell transcriptional profiling, flow cytometry, and imaging. Coordinated cellular and molecular changes occur at 7-14 days of age, designated "transitional ages," as thymus growth switches to homeostasis. E2F target gene expression declines, and the expression of type I interferon response genes increases across diverse cell types at transitional ages. Alterations in thymic stromal …

Regulation Of Insm1 Gene Expression And Neuroendocrine Differentiation In High-Risk Neuroblastoma, Chiachen Chen, Siyuan Cheng, Xiuping Yu, Yisheng Lee, Michael S. Lan

School of Graduate Studies Faculty Publications

Neuroblastoma (NB), a pediatric cancer of sympatho-adrenal (SA) lineage, is marked by disrupted differentiation and cellular heterogeneity. INSM1, a zinc-finger transcription factor, is highly expressed in NB and developing SA tissues, where it regulates neuroendocrine differentiation, especially in chromaffin cells. We investigated INSM1's role in maintaining an undifferentiated, progenitor-like state in NB and its regulation via metabolic and epigenetic mechanisms. Transcriptomic profiling, promoter assays, and metabolic flux analysis revealed that INSM1 expression correlates with methionine cycle activity, particularly the S-adenosylmethionine (SAM)/S-adenosylhomocysteine (SAH) ratio. Disruption of SAM/SAH balance altered INSM1 promoter activity and histone methylation, implicating epigenetic control in NB cell …

ΔFOSB, a member of the AP-1 family of transcription factors, mediates long-term neuroadaptations underlying drug addiction, seizure-related cognitive decline, dyskinesias, and several other chronic conditions. AP-1 transcription factors are notoriously difficult to modulate pharmacologically due to the absence of well-defined binding pockets. Here, we identify a novel site on ΔFOSB, located outside the DNA-binding cleft, that accommodates small molecules. We show that sulfonic acid-containing compounds bind to this site via an induced-fit mechanism, reorienting side chains critical for DNA binding, and that they may hinder the ΔFOSB bZIP α-helix from binding to the major groove of DNA. In vivo, direct …

Objective: A modeling and simulation tool, OpenSim, was used to determine the optimal relationship between actuator stiffness and actuation timing of a passive ankle exoskeleton for reducing metabolic costs during walking. We hypothesized that the absolute minimum in total metabolic cost would exist at an actuation timing of 15% of stance and at a spring stiffness of 7.5 kN/m. We also hypothesized that a local minimum in total metabolic cost would exist at an actuation timing of 50% of stance. Methods: Bilateral kinematics and kinetics data were collected on a healthy male walking overground wearing his regular tennis shoe. The …

Trait-Like Visual Cortical Hyperactivity In Trait Anxiety, Zhaohan Wu, Yuqi You, Joshua A Brown, Raymond J Dolan, Wen Li

Faculty, Staff and Student Publications

Sensory processing varies across individuals, with some traits-particularly sensory hypersensitivity to basic non-valenced stimuli-linked to emotional traits and psychiatric risk. Traditional accounts attribute this sensory-emotion linkage to limbic or prefrontal modulation, but empirical support is limited. Growing evidence suggests sensory cortex itself flexibly encodes value beyond labeled-line analysis. Across four high-density EEG experiments with multi-wave assessments, we identified reliable visual cortical hyperactivity in high trait anxiety. The effect emerged as early as 46 ms, localized to V1/V2, and was specific to the parvocellular pathway. It was reproducible across arousal states, stimulus valence, extended intervals, and paradigms, and evident for both …

Duncan NRI Faculty and Staff Publications

Rhizomelic chondrodysplasia punctata type 1 (RCDP1) is a peroxisomal disorder characterized by skeletal shortening, intellectual disability, seizures, cataracts, and reduced lifespans. RCDP1 is caused by biallelic loss-of-function variants in PEX7, which encodes a protein required for importing select enzymes into the peroxisome matrix, including those essential for ether lipid synthesis (e.g., plasmalogens) and the branched-chain fatty acid catabolism. Plasmalogen deficiency is a hallmark of RCDP1 and other peroxisomal disorders, including RCDP types 2-5 (RCDP2-5) and Zellweger spectrum disorders (ZSD). Here, we performed comprehensive metabolomic profiling of clinical samples from RCDP patients and Pex7-deficient mouse models. We identified profound …

Peripheral Blood Biomarkers For Rheumatoid Arthritis-Associated Interstitial Lung Disease, Brent A. Luedders

Theses & Dissertations

Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a common extra-articular complication of rheumatoid arthritis (RA). Measuring peripheral blood biomarkers represents an appealing strategy to inform the screening and prediction of RA-ILD. In these studies, I aimed to further characterize the associations of peripheral blood biomarkers with prevalent and incident RA-ILD. First, I evaluated the associations of matrix metalloproteinases (MMPs) with RA-ILD among a multicenter cohort of RA U.S. Veteran patients (n = 2,312). Higher concentrations of MMP-7 and MMP-9 were independently associated with both prevalent and incident RA-ILD, including a nearly four-fold increased odds of prevalent RA-ILD (adjusted odds ratio …

The Effect Of Glp-1 Receptor Agonists On Reoperation Following Anterior Cervical Discectomy And Fusion, Nicholas C. Bank, Daniel Whittingslow, Sam Duggan, Joshua L. Morningstar, Douglas S. Weinberg

Student Papers, Posters & Projects

BACKGROUND: Pseudarthrosis remains a significant complication of ACDF, contributing to patient morbidity and increased healthcare costs. Glucagon-like peptide-1 receptor agonists (GLP-1RA), widely prescribed for diabetes and obesity, have been shown to reduced odds of pseudoarthrosis after ACDF. However, it remains unclear whether these reductions meaningfully translate to reduced odds of subsequent cervical surgery.

METHODS: The TriNetX United States Collaborative Network was queried for patients who underwent single- or multi-level ACDF between 2013-2023. Patients with perioperative GLP-1RA use and propensity-score-matched controls without GLP-1RA use were compared for subsequent rates of pseudoarthrosis and cervical reoperation at 6-, 12-, and 24-month intervals. Odds …
