Lafora disease (LD) is a fatal childhood progressive myoclonus epilepsy and glycogen storage disease that is caused by recessive mutations in either EPM2A or EPM2B. The hallmarks of LD are cytoplasmic, aberrant glycogen-like aggregates, called Lafora bodies (LBs), that drive disease progression. The 9th Annual Lafora Science Symposium was held in San Diego, California and brought together over 70 researchers, clinicians, academic trainees, and friends and family members of patients with LD and 80 attendees joined virtually. This symposium focused primarily on international collaborations for therapeutic development and biomarker identification and strategies for preparing the Lafora community for upcoming …

Phospholipase C isozymes (PLCs) hydrolyze phosphatidylinositol 4,5-bisphosphate (PIP₂) into inositol 1,4,5-trisphosphate (IP₃) and diacylglycerol (DAG), important signaling molecules involved in many cellular processes including Ca²⁺ release from the endoplasmic reticulum (ER). PLCG1 encodes the PLCγ1 isozyme that is broadly expressed. Hyperactive somatic mutations of PLCG1 are observed in multiple cancers, but only one germline variant has been reported. Here, we describe seven individuals with heterozygous missense variants in PLCG1 [p.(Asp1019Gly), p.(His380Arg), p.(Asp1165Gly), and p.(Leu597Phe)] who present with hearing impairment (5/7), ocular pathology (4/7), cardiac septal defects (3/6), and various immunological issues (5/7). To model these …

Concurrent use of medications can modulate the effectiveness of immunotherapy. Although this interaction is well documented for immune checkpoint inhibitors, whether this occurs with new experimental compounds has not been evaluated. A computerized data extraction tool was used to collect clinical data and identify the prescription of a predefined set of medications within 30 days of immunotherapy infusion in the Department of Investigational Cancer Therapeutics at The University of Texas MD Anderson Cancer Center. The primary endpoints were median overall survival (OS) and progression-free survival. Tumor responses were addressed using RECIST. We identified 897 patients. The most prevalent tumor types …

Nf1-Depleted Er+ Breast Cancers Are Differentially Sensitive To Cdk4/6 Inhibitors, Ze-Yi Zheng, Anran Chen, Eric J Jaehnig, Meenakshi Anurag, Jonathan T Lei, Long Feng, Chenwei Wang, Diana Fandino, Purba Singh, Hilda Kennedy, Ghazal Yadav, Craig T Vollert, Jill Tsai, Xi Chen, Yi Li, Bora Lim, Alastair Thompson, Shunqiang Li, Charles E Foulds, Bing Zhang, Matthew J Ellis, Eric C Chang

Neurofibromin/NF1 is a RAS (rat sarcoma virus) GTPase activating protein and estrogen receptor (ER) transcriptional corepressor. NF1low status, identified by copy number loss or low mRNA/protein expression is associated with endocrine therapy resistance in approximately 20% of ER+/HER2− (human epidermal growth factor receptor 2) early-stage breast cancers. The identification of targeted treatments for NF1low ER+/HER2− breast cancer is therefore a priority. In this study proteogenomic analysis of ER+/HER2− breast cancer demonstrated that NF1low tumors exhibited elevated cyclin-dependent kinase 4/6 (CDK4/6) activity. In cell lines, NF1-deletion had a dual effect on CDK4 activity. First, by promoting ER recruitment to CCND1 …

Introduction: Research indicates a strong correlation between obesity and the risk of dementia, both are linked to steroid receptor coactivator-1 (SRC-1), a transcriptional coactivator.

Methods: We used RNA sequencing analysis (RNA-Seq) to investigate the transcriptome of SRC-1-KO mice, and identified S100 calcium-binding protein A6 (S100A6), an AD associated gene, as one target of SRC-1. We tested cognitive behaviors in SRC-1-KO mice and mice with a humanized SRC-1 mutation (SRC-1L1376P), and performed promoter luciferase assays on S100A6.

Results: Loss of SRC-1 caused alterations in gene signatures that are commonly associated with neurodegenerative diseases, including AD, and diminished the neural plasticity of …

Cardiac allograft vasculopathy remains a major cause of late morbidity following heart transplantation. While accumulating evidence implicates innate macrophages in the inflammatory progression of CAV, the underlying mechanisms remain incompletely understood. In murine models of CAV, we identified proteolytic cleavage of MERTK, a key anti-inflammatory receptor on macrophages, as a contributing factor to CAV progression. In a model of CAV, MERTK deficiency accelerated allograft rejection and increased intimal leukocyte infiltration. In contrast, mice expressing a genetically cleavage-resistant form of MERTK (MertkCR/CR) exhibited prolonged graft survival, reduced intimal thickening, diminished immune cell infiltration, and decreased circulating effector T cells. …

The Role Of Recruited Adipose Stromal Cells And Their Fibroblastic Differentiation In Cancer, Lingyi Cai, Mikhail G Kolonin, Dimitris Anastassiou

Faculty, Staff and Student Publications

Adipose stromal cells (ASCs) are perivascular mesenchymal progenitors of adipose tissue. In cancer patients, ASCs can mobilize and migrate to the tumor, where they subsequently play an important role in cancer progression. This biological process involves the conversion of recruited ASCs into cancer-associated fibroblasts (CAFs). ASC-derived CAFs influence the tumor microenvironment through extracellular matrix remodeling, vascularization, and immunomodulation. These and other processes mediated by secreted paracrine factors also affect gene expression in carcinoma cells to promote the epithelial-mesenchymal transition (EMT), metabolic adaptation, survival, and invasiveness of cancer cells. ASC-derived CAFs can enhance tumor aggressiveness, accounting in part for the link …

Aerobic glycolysis, termed the Warburg effect, is one of the aberrant metabolic pathways in highly proliferating cells. Glycolysis provides glycolytic metabolites to support the generation of biomass, such as nucleotides, amino acids, and lipids. Research on the direct interactions between glycolysis and other metabolic pathways is an emerging field that has garnered significant interest. Phosphofructokinase-2/fructose-2,6-bisphosphatase 3 (PFKFB3) activates glycolysis by synthesizing fructose-2,6-bisphosphate (F2,6BP), which allosterically activates the rate-limiting enzyme 6-phosphofructo-1-kinase (PFK-1). In this study, we found that PFKFB3 directly interacts with and regulates the phosphorylation of carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase (CAD), the enzyme catalyzing the first three …

Computer-Aided Reading Of Chest Radiographs For Paediatric Tuberculosis: Current Status And Future Directions, Mackenzie Dupont, Robert Castro, Sandra V Kik, Megan Palmer, James A Seddon, Devan Jaganath

Faculty, Staff and Students Publications

Computer-aided detection (CAD) systems for automated reading of chest x-rays (CXRs) have been developed and approved for tuberculosis triage in adults but not in children. However, CXR is frequently the only adjunctive tool for clinical assessment in the evaluation of paediatric tuberculosis in primary care settings, and children would benefit from CAD models that can detect their unique clinical and radiographic features. To advance CAD for childhood tuberculosis, large, diverse paediatric CXR datasets linked to standardised tuberculosis classifications are required. These datasets would be used to train and validate paediatric-specific models for tuberculosis screening, diagnosis, and severity stratification. Previous studies …

High-Speed Voltage Imaging Of Action Potentials In Molecular Layer Interneurons Reveals Sensory-Driven Synchrony That Augments Movement, Spencer T Brown, Meghana R Holla, Michelle A Land, Shuyuan Yang, Alex J Mcdonald, François St-Pierre, Indira M Raman

Faculty, Staff and Students Publications

Testing whether the synchrony of action potential firing is a cerebellar coding mechanism requires simultaneous recording, with high temporal fidelity, from populations of identified neurons. Here, we used targeted one-photon voltage imaging at 2–4 kHz to record action potentials from groups of ~10–300 molecular layer interneurons (MLIs) expressing a positively tuned, genetically encoded voltage indicator, FORCE1f or pAce. In awake resting mice, crus I MLIs fired brief (~1-ms) spikes at 20–60 spikes/s. Sensory stimuli of air puffs to the whiskers evoked short-latency (< 10 ms) increases in spiking probability. In most trials, >50% of MLIs fired synchronously with 4-ms temporal precision. The magnitude of puff-evoked whisks correlated tightly with …

Cathartocytosis: Jettisoning Of Cellular Material During Reprogramming Of Differentiated Cells, Jeffrey W Brown, Xiaobo Lin, Gabriel Anthony Nicolazzi, Xuemei Liu, Thanh Nguyen, Megan D Radyk, Joseph Burclaff, Jason C Mills

Faculty, Staff and Students Publications

Injury causes differentiated cells to undergo massive reprogramming to become proliferative and repair tissue via paligenosis. Gastric chief cells use paligenosis to reprogram into progenitor-like spasmolytic-polypeptide-expressing metaplasia (SPEM) cells. Stage 1 of paligenosis is the downscaling of mature cell architecture via a process involving lysosomes. Here, we notice that sulfated glycoproteins are not only digested during paligenosis but also excreted into the gland. Various genetic and pharmacological approaches show that endoplasmic reticulum membranes and secretory granule cargo are also excreted and that the process proceeds in parallel with but is mechanistically independent of autophagy. Three-dimensional light and electron microscopy demonstrated …

Multiplex Imaging Mass Cytometry Reveals Prognostic Immunosuppressive Subpopulations And Macrophage-Driven Metastasis In Osteosarcoma, Benjamin B Gyau, Junyan Wang, Weiguo Wu, Brooks Scull, Angela M Major, Weidong Jin, Justin M M Cates, John Hicks, Tsz-Kwong Man

Faculty, Staff and Students Publications

Osteosarcoma is a type of bone cancer that mostly affects kids and teens. The biggest danger is when the cancer spreads to the lungs, and current treatments do not work well for those cases. Immunotherapy, which helps the body’s immune system fight cancer, has worked for other cancers but is limited for osteosarcoma because we do not fully understand the environment around the tumor. Our research looked at various cells around the tumor to study why patients have worse outcomes. We found that certain cells, called M2 macrophages (M2) and myeloid-derived suppressor cells (MDSC), which weaken the immune system, are …

Mri-Guided Focused Ultrasound Thalamotomy For Neuropathic Pain In An Adolescent With Cranial Metastases: Illustrative Case, Sarah G Van Winkle, Danika L Paulo, Ashwin Viswanathan, Daniel Curry, Nisha Gadgil

Faculty, Staff and Students Publications

Background: Neuropathic cancer pain (NCP) is a debilitating condition that is often refractory to conventional medical management. MRI-guided focused ultrasound (MRgFUS) central lateral thalamotomy (CLT) is an incisionless neurosurgical option for neuropathic pain palliation, but its use in pediatric patients and those with cranial metastases, a relative contraindication to MRgFUS, remains largely unexamined.

Observations: A 16-year-old male with metastatic rhabdomyosarcoma (RMS) with numerous cranial metastases experienced severe, diffuse, refractory NCP. The patient underwent bilateral CLT with MRgFUS. After the procedure, the patient experienced complete and durable resolution of his neuropathic pain. He only reported occasional somatic pain at sites of …

Astrocytes Expressing Mutant Hnrnpa1 Induce Non-Cell-Autonomous Motor Neuron Death, Qinxue Wu, Xionghao Liu, Tingting Zhang, Shiquan Cui, Bo Huang, Cao Huang, Qilin Cao, Xu-Gang Xia, Hongxia Zhou

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Pathogenic mutation of heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) is causative to amyotrophic lateral sclerosis (ALS). Neuron death resulting from pathogenic hnRNPA1 may not require its presence across all pertinent cells types, including neurons, glia, and muscles. Rather, the exclusive presence of pathogenic hnRNPA1 in a specific cell type, such as astrocytes, may suffice to substantially alter cellular functions. Consequently, this alteration initiates abnormal interaction within intricate neuron-glia networks, culminating in non-cell-autonomous motor neuron death. To investigate the pivotal role of non-cell-autonomous neuron death in hnRNPA1-associated ALS, we developed transgenic rats overexpressing mutant hnRNPA1 in specifically astrocytes. The confined overexpression of …

Background: Regional cerebral blood flow (rCBF) is a putative biomarker for neuropsychiatric disorders, including major depressive disorder (MDD).

Methods: Here, we show that rCBF can be predicted from resting-state functional MRI (rsfMRI) at the voxel level while correcting for partial volume averaging (PVA) artifacts. Cortical patterns of MDD-related CBF differences decoded from rsfMRI using a PVA-corrected approach showed excellent agreement with CBF measured using single-photon emission computed tomography (SPECT) and arterial spin labeling (ASL). A support vector machine algorithm was trained to decode cortical voxel-wise CBF from temporal and power-spectral features of voxel-level rsfMRI time series while accounting for PVA. …

Supporting Healthy Siblings In Pediatric Cancer: Advancing Relational Interventions To Heal Invisible Wounds, Kristen K. Wederski

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Healthy siblings of children diagnosed with cancer occupy a uniquely vulnerable position within the pediatric oncology landscape. Individuals within this population often demonstrate significant emotional distress and can experience long-term psychological challenges. Despite their risk, healthy siblings remain under-researched and under-supported compared to pediatric patients and caregivers. Existing interventions tend to prioritize individual coping skills and psychoeducation and often overlook the critical relational dynamics that shape healthy siblings' psychological adjustment. Grounded in systematic and relational theories, this paper proposes a paradigm shift toward relationally focused interventions that strengthen the caregiver-sibling bond as a core mechanism of change to foster resilience …

Encapsulating peritoneal sclerosis (EPS) is a life-threatening fibrotic condition characterized by severe abdominal adhesions, chronic inflammation, and significant morbidity. The lack of effective treatments for EPS stems from a limited understanding of its underlying mechanisms. In this study, we developed a modified mouse model of PD-induced EPS and investigated the role of the STING signaling pathway in disease progression. Our findings reveal that STING activation in peritoneal mesothelial cells significantly increases the secretion of the macrophage chemokine CCL2, leading to enhanced macrophage infiltration and the formation of pathological adhesions. Notably, pharmacological inhibition of STING using the inhibitor H151 effectively reduced …

While the cause of preterm birth (PTB) (i.e., delivery before 37 weeks of gestation) is likely multifactorial, ambient exposure to environmental chemicals has been postulated to play a role in its etiology. Our prior studies of exposure to polycyclic aromatic hydrocarbons (PAHs) in pregnancy have shown an increased level of placental PAH-induced bulky DNA adducts with increasing levels of PAH exposures. In this investigation, we hypothesized that higher levels of placental PAHs would be associated with an increased risk of PTB. Using gas chromatography and mass spectrometry (GC-MS/MS), we measured levels of benzo(a)pyrene (BaP), benzo(b)fluoranthene (BbF) and dibenz(a,h)anthracene (DBA) from …

Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Accumulating evidence has supported diverse regulatory functions of astrocytes in different neural circuits as well as various aspects of complex behaviors. However, little is known about how astrocytes regulate different neuronal subpopulations that are linked to specific behavioral aspects within a single brain region. Here, we show that astrocytes in the medial prefrontal cortex (mPFC) encode anxiogenic environmental cues in freely behaving mice. Silencing mPFC astrocyte Ca

Cells interact as dynamically evolving ecosystems. While recent single-cell and spatial multi-omics technologies quantify individual cell characteristics, predicting their evolution requires mathematical modeling. We propose a conceptual framework-a cell behavior hypothesis grammar-that uses natural language statements (cell rules) to create mathematical models. This enables systematic integration of biological knowledge and multi-omics data to generate in silico models, enabling virtual "thought experiments" that test and expand our understanding of multicellular systems and generate new testable hypotheses. This paper motivates and describes the grammar, offers a reference implementation, and demonstrates its use in developing both de novo mechanistic models and those informed …

BAF (SWI/SNF) chromatin remodelers engage binding partners to generate site-specific DNA accessibility. However, the basis for interaction between BAF and divergent binding partners has remained unclear. Here, we tested the hypothesis that scaffold proteins augment BAF's binding repertoire by examining β-catenin (CTNNB1) and steroidogenic factor 1 (SF-1, NR5A1), a transcription factor central to steroid production in human cells. BAF inhibition rapidly opposed SF-1/β-catenin enhancer occupancy, impairing SF-1 target activation and SF-1/β-catenin autoregulation. These effects arise due to β-catenin's role as a molecular adapter between SF-1 and an intrinsically disordered region (IDR) of the canonical BAF (cBAF) subunit ARID1A. In contrast …

Organizational Climate And Decision Aid Sustainability In Lupus Care: Mixed Methods Study, Aizhan Karabukayeva, Larry R Hearld, Nathan W Carroll, Reena Kelly, Jasvinder A Singh

Faculty, Staff and Students Publications

Background: Digital decision aids (DAs) are increasingly used in health care to support shared decision-making and promote patient engagement. In the context of systemic lupus erythematosus (SLE), a complex autoimmune disease characterized by diverse symptoms and uncertain prognoses, DAs offer guidance to patients in navigating treatment risks and benefits. Although numerous studies have examined the initial implementation of evidence-based tools, there is limited evidence on the organizational factors that influence their long-term sustainability in clinical practice. This gap is particularly salient for digital interventions, where integration into routine workflows and ongoing use require alignment with clinic readiness and culture. This …

A Religious Etiology Of Genito-Pelvic Pain And Pain With Penetration, Emily L. Carlson

Theses and Graduate Projects

Pelvic pain during penetration (PPDP) has been described using various diagnostic terms, including vaginismus, dyspareunia, and vulvodynia. The most recent and comprehensive classification is Genito-pelvic pain/penetration disorder (GPPPD) which is characterized by psychological distress associated with pain during or in anticipation of vaginal penetration (DSM-5-TR; American Psychiatric Association [APA], 2022). The etiology of PPDP is multifactorial, involving a complex interplay of biological, psychological, and relational factors. Religious and cultural influences may play a significant role in shaping individuals’ experiences of sexual pain. This study investigated the etiology of PPDP in relation to the religious influences among women raised in Judeo-Christian …

Cerebral edema (CE) is a major component of early brain injury from aneurysmal subarachnoid hemorrhage (SAH). Despite the utility of blood-based protein markers, biomarkers targeting cerebral edema have yet to be developed. We performed a targeted proteomic search analyzing 141 proteins in plasma samples taken from 80 adult patients within 48 hours after aneurysmal rupture to identify plasma biomarkers of cerebral edema. The protein expression profiles were analyzed for associations with a higher level of the subarachnoid hemorrhage early brain edema score measured in admission computed tomography scans. Five differentially expressed proteins-brorin, ectodysplasin A2 receptor, layilin, scavenger receptor class A …
