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 …

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 …

Faculty, Staff and Student Publications

Introduction: Poststroke depression (PSD) affects approximately 33% of stroke survivors and is associated with worse outcomes, poor quality of life (QOL) and mortality. Despite its prevalence and consequences, there is no consensus on the most effective strategy for PSD prevention. Behavioural activation (BA) is an effective intervention for depression across diverse populations and is considered safer, better tolerated and a longer-lasting alternative to antidepressant medications. This study aims to test the effectiveness of a remotely delivered BA intervention to prevent PSD (Tele-BA-S).

Methods and analysis: We will conduct a randomised effectiveness trial of 350 low-income adults (≥ 55 years) within …

Background: This secondary analysis of the CONFIDENCE (combination effect of fInerenone and empagliflozin in participants with chronic kidney disease and type 2 diabetes using a UACR endpoint) trial (REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT05254002) assessed systolic blood pressure (SBP) changes with empagliflozin/finerenone combination therapy versus monotherapy in people with chronic kidney disease and type 2 diabetes across baseline SBP categories. We assessed SBP response predictors and whether early (day 30) SBP changes mediate urinary albumin-to-creatinine ratio reductions.

Methods: Participants (n=800) were stratified by baseline SBP (< 130 mm Hg; ≥130 mm Hg). Outcomes included SBP response (≥10 mm Hg reduction from baseline at day 180) and longitudinal SBP changes, analyzed by linear mixed-effects models and logistic regression. Causal mediation analysis, a secondary exploratory analysis, evaluated the effect of day 30 SBP change on day 180 urinary albumin-to-creatinine ratio reduction.

Results: At baseline, 532 (66%) participants had SBP ≥130 mm Hg; 268 (34%) …

Histone Deacetylase Enzyme Activity Is Not The Universal Anticancer Target Of Hdac Inhibitors, Chaitra Rai, Hang Ruan, Xue Li, Wenbo Li, Hyun-Hwan Jeong, Chengchuang Song, Panpan Liu, Yingjie Chang, Hao Fang, Udhaya Kumar S, Yuxiang Sun, M James You, Dongyin Guan, Zhandong Liu, Leng Han, Xuben Hou, Zheng Sun

Histone deacetylase inhibitors (HDIs) are approved for treating hematologic cancers and are currently being evaluated in hundreds of clinical trials for various cancers and other diseases, although their mechanisms of action remain poorly understood. Here, our unbiased bioinformatics analyses found that, for most cancer types, expression levels or genetic variants of histone deacetylase (HDACs) do not consistently correlate with carcinogenesis, do not predict cancer patient survival, and do not associate with cellular responses to HDIs. Whole-genome CRISPR library screens did not identify HDACs as genes affecting cellular responses to HDIs. Overexpression of dominant-negative Class I HDACs causes similar protein hyperacetylation …

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 …

Amc-F1 Regulates Mitochondria-Autophagy Crosstalk Independent Of Nutrient Stress, Yuqin Wang, Raksha K Rao, Trung Vu, Ayano Sekine, Zhengmei Mao, Nami Mccarty

The Brown Foundation: Institute of Molecular Medicine

Mitochondria and autophagy are fundamental yet distinct regulators of cellular homeostasis. Here, we identify AMC-F1 (Autophagy-Mitochondria Coupling Factor 1; formerly TRIM44) as a central integrator of mitochondrial bioenergetics and autophagy. Using Amcf1 knockout and knock-in mouse models, we demonstrate that AMC-F1 bidirectionally regulates these pathways: its loss reduces mitochondrial respiration and autophagic flux, whereas its overexpression promotes mitochondrial elongation and increases autophagy independently of nutrient stress. Transcriptomic analyses reveal AMC-F1-dependent regulation of mitochondrial biogenesis programs that engage autophagy, involving mitochondrial respiratory chain complex genes under basal conditions and mitochondrial organization factors under starvation-induced autophagy. Although dispensable under homeostasis, this coupling …

The Aggregated Latent Profile Index: Measuring Person Profile Differentiation Within A Bootstrap-Validated Latent Profile Space, Se-Kang Kim

Faculty, Staff and Students Publications

Multivariate assessment profiles contain two conceptually distinct sources of variation: overall level and profile shape. Existing approaches recover some aspects of this structure, but none jointly establishes the replicability of latent pattern dimensions and provides a principled, population-referenced summary of person profile differentiation independent of overall level. We introduce the Aggregated Latent Profile Index (ALPI), a variance-weighted Euclidean distance that quantifies the degree to which an individual’s profile departs from a flat population reference within a bootstrap-validated latent profile space. ALPI is derived from the Aggregated Latent Profile Space (ALPS), a framework that combines parallel analysis with bootstrap stability diagnostics …

Biologics, protein- and peptide-based drugs derived from living organisms or cell lines have emerged as effective therapies across a broad range of indications. However, parenteral administration and the need for frequent dosing increase costs and limit compliance, creating an urgent need for innovative platforms capable of continuously, safely, and efficiently delivering sustained biologics in situ within the host. Here, we describe a bioengineered hookworm platform to manufacture and deliver biologic therapeutics in vivo. As proof of concept, we engineer the Ancylostoma ceylanicum secretome by inserting a human single-chain variable fragment antibody (s16-HuScFv) into its genome. Transgene expression does not perturb …

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 …

Complement Activation In Maternal And Placental Pathology Of Preeclampsia, Manu T Banadakoppa, Madhulatha S Chauhan, Moises J Tacam, Allyson W Nevins, Antonio H Ruano, Simone H Ruano, Jon A Fuson, Chandra Yallampalli

Faculty, Staff and Students Publications

Background: Preeclampsia is a multifactorial, pregnancy-related disorder characterized by new-onset hypertension and proteinuria, with distinct early- and late-onset forms. Although complement dysregulation has been implicated in the pathogenesis of preeclampsia, its causal role remains unclear. In mice, Crry (complement receptor 1-related protein Y) functions as a critical complement regulator at the fetal-maternal interface. Because complete Crry deficiency is embryonically lethal, direct in vivo investigation of complement activation in pregnancy has been challenging.

Methods: We generated a placenta-specific, doxycycline-inducible short hairpin RNA mouse model in which Crry expression can be downregulated in a dose-dependent manner. This system employs Cyp19-driven Cre recombinase …

Faculty, Staff and Students Publications

Psychological stress can cause diminished immune response to infectious challenges. The extent this holds true during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the modifying effect of vaccination status is untested. We explored these relationships in a non-random sample standardized to the US adult population. Across 2178 participants in the Aegis study (2021-2022), we identified 507 eligible laboratory-confirmed SARS-CoV-2 infections. We estimated the natural log of nucleocapsid-binding antibody absorbance (N-antibody) at study visits up to 225 days following a positive SARS-CoV-2 test. Linear mixed effects models were fit to estimate the association of baseline perceived stress and, separately, …

Genetic Architecture Of White Matter Microstructure Captured By Unsupervised Deep Representation Learning Of Fractional Anisotropy Maps, Xingzhong Zhao, Ziqian Xie, Wei He, Hyun Yong Koh, Bohong Guo, Han Chen, Myriam Fornage, Degui Zhi

The Brown Foundation: Institute of Molecular Medicine

Fractional anisotropy (FA) from diffusion MRI is a widely used marker of white matter (WM) integrity, but conventional FA-based genetic studies typically rely on tract- or atlas-defined averages that may obscure spatially distributed WM variation and limit genetic discovery. Here, we propose a deep learning framework, termed unsupervised deep representation of WM (UDR-WM), which uses voxel-wise FA maps to derive brain-wide unsupervised deep imaging phenotypes (UDIP-FA) without prior anatomical assumptions. Compared with traditional FA phenotypes, UDIP-FA shows greater sensitivity to aging and substantially higher SNP-based heritability. Multivariate GWAS identified 939 lead SNPs across 586 loci, mapping to 3,480 UDIP-FA-associated genes. …

From Performance To Practice: Knowledge-Distilled Segmentator For On-Premises Clinical Workflows, Qizhen Lan, Aaron Choi, Jun Ma, Bo Wang, Zhongming Zhao, Xiaoqian Jiang, Yu-Chun Hsu

Faculty, Staff and Student Publications

Deploying medical image segmentation models in routine clinical workflows is often constrained by on-premises infrastructure, where computational resources are fixed and cloud-based inference may be restricted by governance and security policies. While high-capacity models achieve strong segmentation accuracy, their computational demands hinder practical deployment and long-term maintainability in hospital environments. We present a deployment-oriented framework that leverages knowledge distillation to translate a high-performing segmentation model into a scalable family of compact student models without modifying the inference pipeline. The framework is primarily evaluated on nnU-Net, with additional validation across transformer and heterogeneous teacher–student architectures. The proposed approach preserves architectural compatibility …

Nmda Receptor Subunit Nmr-2 Regulates Pathogen-Induced Immune Responses Via The Nervous System In C. Elegans, Benson Otarigho, Jonathan Lalsiamthara, Alejandro Aballay

Faculty, Staff and Student Publications

Neural control of innate immunity must balance restraint of basal immune activity with rapid activation upon pathogen encounter. Glutamate, the primary excitatory neurotransmitter in the nervous system, has been implicated in several neurological disorders associated with inflammation, suggesting a potential link to immune regulation. However, how glutamatergic signaling contributes to immune balance remains unknown. Here, we demonstrated that the NMDA-type ionotropic glutamate receptor subunit NMR-2, a component of the NMDA receptor complex, acts in the
