Faculty, Staff and Student Publications

Introduction: Chronic musculoskeletal pain (CMP) is a leading cause of incurred personal healthcare costs and disability in the USA. It disproportionately affects rural populations, who are more likely to be uninsured, lack access to a regular healthcare provider and experience a higher prevalence of CMP. As a result of reduced access to non-pharmacological care, there is greater reliance on opioids. The Auricular Point Acupressure - Self-Management (APA-SM) program is a simple, needleless, evidence-based therapy that empowers individuals to self-manage their pain. Preliminary studies, including a recent UG3 pilot testing, demonstrated feasibility, safety and significant improvements in pain and function. Guided …

Development And Preliminary Validation Of Orca-Pd, An Online Rapid Cognitive Assessment For Parkinson Disease: Mixed Methods Study, Avigail Lithwick Algon, Sarah Brisman, Chi-Ying R Lin, William Saban

Faculty, Staff and Students Publications

Background: Traditional in-person neuropsychological tests for Parkinson disease (PD) lack accessibility, scalability, and PD specificity. Mobility impairments hinder access to in-person assessments, and long waiting times for expert evaluation limit scalability. Common tools for cognitive screening, such as the Montreal Cognitive Assessment, are generic and not specific to PD.

Objective: The goal of this study was to address these challenges by leveraging the internet. This study aimed to develop a sensitive tool to detect cognitive impairments in early- to mid-stage PD in an accessible and scalable manner.

Methods: We developed the Online Rapid Cognitive Assessment for Parkinson's Disease (ORCA-PD), a …

Notch1 Acts As A Tumor Suppressor That Induces Early Differentiation In Head And Neck Cancer, Chenfei Huang, Shhyam Moorthy, Qiuli Li, Kazi M Ahmed, Kalil Saab, Defeng Deng, Jiping Wang, Xiayu Rao, Jiexin Zhang, Yuanxin Xi, Jing Wang, Zhiyi Liu, Noriaki Tanaka, David A Wheeler, Eve Shinbrot, Rami Saade, Curtis R Pickering, Tong-Xin Xie, Adel K El-Naggar, Abdullah A Osman, Kunal Rai, Patrick A Zweidler-Mckay, John V Heymach, Lauren A Byers, Faye M Johnson, Vlad C Sandulache, Jeffrey N Myers, Pedram Yadollahi, Mitchell J Frederick

Inactivating NOTCH1 mutations in head and neck squamous cell carcinoma (HNSCC) were described over a decade ago, suggesting a tumor suppressor function - unlike its oncogenic role in other tumors. Today, much debate persists regarding a putative oncogenic role in HNSCC as well, with reports that NOTCH1 signaling drives tumor growth and a cancer stem cell (CSC) phenotype. In this work, comprehensive experiments unequivocally demonstrate that NOTCH1 is a tumor suppressor in HNSCC regardless of mutation or activation status and that it reduces CSC frequency. We developed a signature of NOTCH1 activation showing the pathway is associated with very early …

Monoclonal Antibodies Targeting Pcdh7 Inhibit Tumor Growth And Enhance Immune Responses In Kras-Mutant Non-Small Cell Lung Cancer, Nicole Novaresi, Poorva Ghosh, Shayna Thomas-Jardin, Hui Deng, Xuejun Fan, Zhiqiang Ku, Wei Xiong, Xiaorong Zhou, Jingfei Zhu, Huiyu Li, Mahesh S Padanad, Bethany Smith, Chul Ahn, John D Minna, Zhiqiang An, Ningyan Zhang, Kathryn A O'Donnell

The Brown Foundation: Institute of Molecular Medicine

We identified an important oncogenic role for protocadherin 7 (PCDH7), a cell surface protein frequently overexpressed in lung adenocarcinoma and associated with poor clinical outcome. Pcdh7 depletion reduces tumor burden and prolongs survival in KrasLSL-G12D; Tp53fl/fl mice. These findings nominate this cell surface protein as an actionable therapeutic target and highlight the therapeutic potential of PCDH7 inhibition for non–small cell lung cancer. We report the development and characterization of high-affinity anti-PCDH7 monoclonal antibodies (mAbs) that inhibit downstream mitogen-activated protein kinase (MAPK) pathway activation and suppress tumor growth in multiple mutant KRAS–driven models. A lead mAb (mAb7) sensitized tumors …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Mitochondria undergo fusion and fission. While DRP1 regulates fission, fusion is controlled by OPA1, MFN1, and MFN2. The balance between these processes and the crosstalk between machineries remains poorly understood. MFN2 mutations cause Charcot-Marie-Tooth disease type 2 A (CMT2A), affecting mitochondrial fusion and morphology. However, their role in fission is unclear. Using skin fibroblasts from CMT2A patients (L248H and M376V MFN2 mutations) and wild-type mouse embryonic fibroblasts expressing these variants, we studied how MFN2 mutations impact mitochondrial dynamics beyond fusion. We analyzed mitochondrial morphology and dynamics by live-cell confocal microscopy and tested fusion/fission protein levels, oxygen consumption rate (OCR), extracellular …

Lipoprotein(a) (Lp(a)) is a genetically determined causal risk factor for cardiovascular disease, with approximately 20% of the population exhibiting elevated levels. While there are promising drugs in development, there are currently no approved therapies specifically designed to lower Lp(a) levels. For high-risk individuals with extreme levels of Lp(a), liver-directed genome editing could be an effective one-time solution. Genome editing approaches such as CRISPR and TALENs can reduce Lp(a) in LPA-transgenic mouse models, but they frequently induce large and potentially harmful genomic deletions. Here, we report the first application of TadA-derived cytosine base editing (CBE), delivered via helper-dependent adenovirus (HDAdV) and …

The Future Of Epilepsy Care In The United Kingdom: A Roadmap For Technology-Enabled Transformation, Rohit Shankar, John Terry

Peninsula Medical School

Epilepsy is recognized to be a significant cause of premature mortality, socio-economic distress and poor quality of life in economically developed countries. Despite clear clinical guidelines, epilepsy care is marked by delayed diagnosis, fragmented management, high emergency admission rates, and pronounced health inequalities affecting rural populations, ethnic minority groups, and people with intellectual disabilities. Diagnostic pathways remain inefficient, with prolonged waits for electroencephalography (EEG), low sensitivity of routine investigations, and repeated inconclusive testing. Long-term management continues to depend on infrequent hospital visits and unreliable patient recall, contributing to suboptimal seizure control, avoidable morbidity, and preventable mortality. In the United Kingdom, …

Rethinking Ethics For An Era Of Trusted Computational Tools, Kristin M Kostick-Quenet, Meghan Hurley, John Herrington, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

Computer perception (CP) technologies are poised to deliver near real-time behavioral insights with high precision. As technical barriers recede, our field's ethical focus must shift from "Can we trust the data?" to "Should we use it here, and how?" We propose a contextual ethics framework that: (1) defines the appropriate scope of CP integration; (2) advocates codesigned roadmaps to manage expectations and epistemic conflict; (3) expands evaluation beyond performance metrics to humanistic outcomes; and (4) anticipates future high performance systems to safeguard dignity, empathy, and shared decision-making in clinical care.

A Phase 4, Open-Label, Non-Randomized, Multicenter Study To Evaluate Efficacy (And Safety) Of Intravenous Administration Of Optison For Contrast-Enhanced Echocardiography In Pediatric Patients, Arash Sabati, Shuo Wang, Pushpa Shivaram, Joshua Hawley, David Thompson, Francine Erenberg, Shelby Kutty, Aparna Kulkarni, Tam T Doan, Joshua D Robinson

Faculty, Staff and Students Publications

Contrast-enhanced echocardiography (CE-echo) is commonly used in adult patients to optimize endocardial border delineation (EBD) but there is limited experience in children. A prospective, open-label, non-randomized, multicenter study was performed to evaluate the efficacy of intravenous Optison for CE-echo in pediatric patients and determine the optimal dose of Optison. Subjects ≥ 9 and <  18 years with suboptimal echocardiograms (defined as ≥ 2 contiguous segments that could not be adequately visualized) were enrolled. After a baseline non-contrast echocardiogram (NC-echo), CE-echo was performed with 2 dose levels of Optison based on patient weight. The primary endpoint was visualization of the LV wall segments (LVWS) in apical 2- and 4-chamber views. An EBD score was calculated by assigning a value from 0 (no visualization) to 3 (optimal visualization) for 12 LVWS. 37 subjects across 8 sites completed the study. 30 had complete echocardiograms at both dose levels. 2 patients had usable images at dose 2 only. Mean age was 13.4 years (± 2.6) with 23 males (62%). Mean weight was 73.9 kg (± 36.8) with wide distribution of weight (interquartile range of 42-102 kg). There were 8 patients under 40 kg. Most subjects had a prior medical/surgical history (n = 33, 89%). Both dose levels of Optison CE-echo improved the number of LVWS visualized from 3.7 ± 1.1 on NC-echo to 10.0 ± 0.1 with dose 1 (p <  0.001) and 10.5 ± 0.1 with dose 2 (p <  0.001). EBD score also improved at both dose levels from 11.9 ± 2.5 for NC-echo to 28.5 ± 1.7 for dose 1 (p <  0.001) and 30.2 ± 8.4 for dose 2 (p <  0.001). The number of suboptimal echocardiograms improved from 92.3% ± 10.7 in NC-echo to 26.2% ± 9 with dose 1 (p <  0.001) and 30.8% ± 4.5 with dose 2 (p <  0.001). CE-echo with intravenous Optison in pediatric patients improved the number of LVWS visualized, improved EBD score, and reduced the number of suboptimal echocardiograms at both dosages used in this study. Intravenous Optison can improve LV visualization in pediatric patients with suboptimal echocardiograms.

Center for Translational Medicine Faculty Papers

MCU, originally known as CCDC109A, is widely recognized as the gene responsible for encoding a pore-forming subunit of a Ca2+-selective channel, mitochondrial Ca2+ uniporter complex (mtCUC). While MCU expression is typically highly mitochondrial-specific, we report here a protein variant derived from the MCU gene, termed MCU-S, which lacks the mitochondria-targeting sequence (MTS) and forms a Ca2+-permeable channel outside of mitochondria. The mRNA of MCU-S was ubiquitously expressed in all cell types/tissues tested, with particularly high expression in human platelets. MCU-S protein formed Ca2+ channels at the plasma membrane, which exhibited similar channel properties to those observed in mtCUC. MCU-S channels …

The intratumoral microbiome is increasingly recognized as a regulator of cancer biology, yet sex-specific patterns and their relevance to cancer disparities remain poorly understood. We perform a multi-kingdom analysis of more than 5,000 tumors from seven datasets to identify sex-differential microbial taxa across aerodigestive and gastrointestinal cancers. We identify and validate 22 taxa with consistent sex-biased abundance, including in real-world cohort. These microbes show cancer-type- and microbe-specific associations with tumor transcriptomes, oncogenic pathways, and immune cell infiltration. Female-enriched microbes are linked to increased estrogen signaling and interferon responses, whereas male-enriched taxa show opposing patterns. In gastric cancer, intratumoral Epstein-Barr virus …

Faculty, Staff and Students Publications

Background: Human papillomavirus (HPV) is a sexually transmitted virus that causes various oropharyngeal and anogenital cancers. The HPV vaccine provides protection against several strains of HPV and is a key preventative tool against HPV-related cancers; however, vaccination rates remain suboptimal in the United States due to variable state mandates and misperceptions of vaccine efficacy and risks. As social media becomes an increasingly popular avenue for health discussions, platforms such as Reddit offer opportunities to understand public vaccine discourse, particularly among underrepresented groups. Furthermore, vaccine hesitancy and mistrust generally increased during the COVID-19 pandemic, potentially impacting HPV vaccination rates.

Imbalance In Wnt: Retinoic Acid Signaling Dysregulates Hox Gene Expression: Implications For Cancer Stem Cell Heterogeneity And Crc Patient Survival, Brian Osmond, Chi Zhang, Pascal K. Kataboh, Caroline O. B. Facey, Lynn M. Opdenaker, Bruce M. Boman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

How HOX transcription factors play a role in the stem cell (SC) origin of cancer is unclear. Our goal is to determine how dysregulation of HOX gene expression promotes colorectal cancer (CRC) development through aberrant SC regulatory mechanisms. We investigated retinoic acid (RA) and WNT signaling because they regulate HOX expression and both pathways are dysregulated in cancer. Previously, we reported WNT and RA pathways are functionally linked, and in CRC, APC mutation generates a WNT:RA imbalance leading to incomplete differentiation and SC overpopulation. We hypothesize that aberrant WNT- and RA-signaling dysregulates HOX expression that contributes to the SC origin …

Quantification Of Sarm1 Nadase Activity In Human Peripheral Blood Mononuclear Cells, Lila F Dabill, Ivana R Shen, Jennifer M Brazill, Alicia Neiner, Yo Sasaki, Erica L Scheller

2020-Current year OA Pubs

SARM1 (sterile α and TIR motif-containing protein-1) is an NADase enzyme that serves as the central executioner of Wallerian axon degeneration. Given this, SARM1 is of high interest as a candidate therapeutic target, and SARM1 inhibitors are currently in clinical trials for treatment of neurodegeneration. Beyond neuroscience, emerging studies reveal that SARM1 may also drive aspects of bone fragility, liver pathology, adipose expansion, and insulin resistance in metabolic disease. However, we lack methods to quantify SARM1 activation in humans to better define patients at high risk of SARM1-mediated tissue damage. Unlike neurons, peripheral blood mononuclear cells (PBMCs) represent an easily …
