Osteosarcoma, the most common childhood bone tumor, can occur in rare cancer predisposition syndromes; however, most cases are sporadic with no known predisposing factors. We investigated the frequency of SMARCAL1 putative pathogenic variants in our large ongoing study of 2,119 osteosarcoma cases, their relation to patient characteristics, and the population prevalence. Our analysis uncovered a higher frequency of SMARCAL1 pathogenic variants across three osteosarcoma case sets (1.8%, n = 2,119) than in 2,625 comparably sequenced cancer-free controls (0.3%; P <  .001). Cases with SMARCAL1 pathogenic variants had significantly improved overall survival compared to cases without these variants (hazard ratio 0.36, 95% CI 0.14-0.96, P = .034). In the UK Biobank (469,557 exomes), there was a 33-fold increased risk of osteosarcoma in individuals with SMARCAL1 pathogenic variants. These results identify SMARCAL1 as a new osteosarcoma predisposition gene and thus warrant follow-up to identify the mechanisms by which SMARCAL1 contributes to the etiology of osteosarcoma.

Lysosomes Signal Through The Epigenome To Regulate Longevity Across Generations, Qinghao Zhang, Weiwei Dang, Meng C Wang

Faculty, Staff and Students Publications

The epigenome is sensitive to metabolic inputs and crucial for aging. Lysosomes act as a signaling hub to sense metabolic cues and regulate longevity. We find that lysosomal metabolic pathways signal through the epigenome to regulate transgenerational longevity in Caenorhabditis elegans. Activation of lysosomal lipid signaling and lysosomal adenosine monophosphate-activated protein kinase (AMPK) or reduction of lysosomal mechanistic-target-of-rapamycin (mTOR) signaling increased expression of a histone H3.3 variant and increased its methylation on K79, leading to lifespan extension across multiple generations. This transgenerational pro-longevity effect required intestine-to-germline transportation of histone H3.3 and a germline-specific H3K79 methyltransferase, and was recapitulated by …

Faculty, Staff and Students Publications

Mixed lineage leukemia (MLL) gene rearrangements cause ~75% of acute leukemia in infants and 5-10% in children and adults with poor clinical outcomes. Protein-protein interactions (PPI) between frequent MLL fusion partners AF9/ENL and AF4 or histone methyltransferase DOT1L are drug targets for MLL-rearranged (MLL-r) leukemia. Sixty-seven quinoxiline compounds were synthesized and tested for their ability to inhibit such PPIs. Compounds 16, 17, 59 and 63 were found to be potent inhibitors with IC50 values of 0.35-1.5 μM. Structure-activity relationships are discussed. Potent inhibitors can suppress expression of MLL target genes Myc and Meis1 and selectively block proliferation of MLL-r and …

Approach To Ophthalmic Surgery Involving The Anterior Vitreous: A Clinical Practice Update From The American Society Of Retina Specialists, Matthew R Starr, Christina Y Weng, Lejla Vajzovic, Kevin J Blinder, Judy E Kim, J Michael Jumper

Faculty, Staff and Students Publications

When encountering diseases of the anterior vitreous and peripheral retina (ie, the "middle segment" of the eye), vitreoretinal (VR) surgeons are specifically trained in surgical techniques for managing the vitreous and visualizing the peripheral retina during anterior vitrectomy, and therefore they are well equipped to address the complications of surgery involving the anterior vitreous space. This clinical update reviews and compares the current literature discussing techniques and patient outcomes related to complete pars plana vitrectomy versus incomplete, subtotal pars plana vitrectomy, and addresses the proposition of developing an abridged training curriculum for non-VR surgeons to acquire the knowledge and skills …

Association Of Genetic Scores Related To Insulin Resistance With Neurological Outcomes In Ancestrally Diverse Cohorts From The Trans-Omics For Precision Medicine (Topmed) Program, Chloé Sarnowski, Yixin Zhang, Farah Ammous, Lincoln M P Shade, Daniel Dicorpo, Xueqiu Jian, Donna K Arnett, Thomas R Austin, Alexa Beiser, Joshua C Bis, John Blangero, Eric Boerwinkle, Jan Bressler, Joanne E Curran, Charles S Decarli, Harsha Doddapaneni, Josée Dupuis, David W Fardo, Jose C Florez, Stacey Gabriel, Richard A Gibbs, David C Glahn, Namrata Gupta, Hector M González, Kevin A González, Konstantinos Hatzikotoulas, Kathleen M Hayden, Susan R Heckbert, Bertha Hidalgo, Alicia Huerta-Chagoya, Timothy M Hughes, Sharon L R Kardia, Charles L Kooperberg, Lenore J Launer, W T Longstreth, Ravi Mandla, Rasika A Mathias, Andrew P Morris, Thomas H Mosley, Ilya M Nasrallah, Paul Nyquist, Bruce M Psaty, Qibin Qi, Laura M Raffield, Nigel W Rayner, Alexander P Reiner, Claudia L Satizabal, Elizabeth Selvin, Magdalena D R Sevilla-Gonzalez, Albert V Smith, Jennifer A Smith, Kirk Smith, Beverly M Snively, Lorraine Southam, Tamar Sofer, Ken Suzuki, Henry J Taylor, Miriam S Udler, Karine A Viaud-Martinez, Sylvia Wassertheil-Smoller, Alexis C Wood, Lisa R Yanek, Xianyong Yin, Alisa K Manning, Jerome I Rotter, Stephen S Rich, James B Meigs, Myriam Fornage, Sudha Seshadri, Alanna C Morrison, Topmed Neurocognitive Working Group, Topmed Diabetes Working Group

To better characterize the potential biological mechanisms underlying insulin resistance (IR) and dementia, we derive cross-population and population specific polygenic scores [PSs] for fasting insulin and IR-related partitioned PSs [pPSs]. We conduct a cross-sectional study of the associations of these genetic scores with neurological outcomes in >17k participants (36% men, mean age 55 yrs) from the Trans-Omics for Precision Medicine (TOPMed) program (50% Non-Hispanic White, 23% Black/African American, 21% Hispanic/Latino American, and 4% Asian American). We report significant negative associations (P <  0.002) of the cross-population (P = 1.3 × 10-5) and European (PEA = 3.0 × 10-8) fasting insulin PSs with total cranial volume, and of a metabolic syndrome European PS with general cognitive function (BEA = -0.13, PEA = 0.0002) and lateral ventricular volume (BEA = 0.09, PEA = 0.002). We identify suggestive negative associations (P <  0.007) of metabolic syndrome and obesity pPSs with general cognitive function, and of lipodystrophy pPSs with total cranial volume. A higher genetic predisposition to IR is associated with lower brain size, and a genetic predisposition to specific IR-related type 2 diabetes subtypes, such as metabolic syndrome and mechanisms of IR mediated through obesity and lipodystrophy, is potentially involved in cognitive decline.

Adenylosuccinate lyase deficiency (ADSLd) is a rare autosomal recessive purine metabolism disorder with several clinical manifestations. While toxic substrate accumulation is a known hallmark, no additional molecular mechanisms have been established. Here, we show that ADSLd is associated with mitochondrial dysfunction, including increased fragmentation, impaired respiration, and reduced ATP production. The severity of mitochondrial impairment correlates with ADSLd pathology, especially in mitochondria-dependent tissues. We also identify defects in mitochondrial dynamics and transport linked to ERK2 and AKT suppression. Notably, overexpressing constitutively active ERK2 or supplementing purine intermediates partially rescues the mitochondrial phenotype. These findings suggest an alternative disease mechanism and …

Mt1-Mmp Inhibition Rejuvenates Ageing Brain And Rescues Cognitive Deficits In Obesity, Pallavi Asthana, Liguo Li, Lin Lu, Jiayan Wu, Shuo Zhang, Ningning Li, Sheung Kin Ken Wong, Susma Gurung, Yijing Zhang, Yuwan Lin, Yufeng Peng, Zongtang Xu, Kui Ming Chan, Lixiang Zhai, Aiping Lyu, Zhao-Xiang Bian, Xin Ge, Ashok Iyaswamy, Min Li, Ya Su, Zhongjun Zhou, Pingyi Xu, Hoi Leong Xavier Wong

Obesity has been linked to an increased risk of cognitive impairment and dementia in later life. Although aging and obesity are both associated with cognitive decline, it remains unclear how they interact to affect cognitive function across the lifespan and how brain function might mediate their relationship with cognition. Our previous findings and other studies have shown that membrane type 1-matrix metalloproteinase (MT1-MMP/MMP14), which increases with age, regulates energy homeostasis. Inhibiting MT1-MMP improves insulin sensitivity, reduces body fat, and lowers serum cholesterol. Here, we demonstrate that MT1-MMP links neuroinflammation to cognitive decline in aging and obesity. Inflammatory responses in the …

Specifically, we present a publicly available, manually annotated corpus derived from Amazon reviews of health-related products and develop baseline natural language processing models using deep …

Deciphering The Mycn-Driven Metabolic Microenvironment Of Neuroblastoma, Amber Wolf, Davide Leardini, Lingzhi Li, Riccardo Masetti, Costas A Lyssiotis, Eveline Barbieri

Faculty, Staff and Students Publications

Oncogenic MYCN drives aggressive disease in many cancers including neuroblastoma (NB). Metabolic reprogramming is essential to support cancer cell homeostasis and survival under nutrient- and oxygen-deprived conditions. MYCN directly reprograms many nodes of tumor-intrinsic metabolism, which have significant repercussions on the cells of the tumor microenvironment (TME), resulting in complex intercellular metabolic circuits that contribute to the immunosuppressive microenvironment of NB. These metabolic circuits are also regulated by the organismal and cellular circadian clock and host diet to further impact the TME and NB oncogenesis. This review discusses the mechanisms by which MYCN regulates the metabolic crosstalk between tumor, TME, …

Dietary Methionine Restriction Primes T Cell Metabolism For Activation And Tumor Inhibition And Enhances The Efficacy Of Immune Checkpoint Blockade, Xiaoqing Qing, Binita Chakraborty, Panpan Liu, Sandeep Artham, Patrick K Juras, Dongyin Guan, Kristen E Pauken, Ching-Yi Chang, Xia Gao

Faculty, Staff and Students Publications

The proliferation of many cancer cells is methionine dependent and dietary methionine restriction (MR) has shown anti-tumor effects in a wide variety of immunodeficiency preclinical models. Yet, whether MR exerts an anti-tumor effect in the presence of an immune-competent background remains inconclusive. Accumulating evidence has shown an essential role of methionine in immune cell differentiation and function. Thus, competition for methionine between tumor cells and immune cells in the tumor microenvironment may drive tumor growth and tumor response to therapy. Here, we aim to define the impact of MR on tumor growth and associated immunity. We first assessed the effect …

Faculty, Staff and Students Publications

The Hippo pathway controls organ development, homeostasis, and regeneration primarily by modulating YAP/TEAD-mediated gene expression. Although emerging studies report Hippo-YAP dysfunction after viral infection, it is largely unknown in the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we analyzed RNA sequencing data from human-induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) and SARS-CoV-2-infected human lung samples, and observed a decrease in YAP target gene expression. In screening SARS-CoV-2 nonstructural proteins, we found that nonstructural protein 13 (NSP13), a conserved coronavirus helicase, inhibits YAP transcriptional activity independent of the upstream Hippo kinases LATS1/2. Consistently, introducing NSP13 into mouse cardiomyocytes suppresses …

"I Just Really Felt Like I Was Heard For The First Time": Survivor Experiences With An Adult Forensic Interviewing Model, Morgan E Pettyjohn, Aly Kramer Jacobs, Khara Breeden, Bethany L Backes, Leila Wood

Faculty, Staff and Student Publications

Adult forensic interviewing (AFI) collects evidence for the investigation and prosecution of interpersonal violence in a trauma-informed setting. The present study uses mixed methods evaluation data from an AFI program in the U.S. to assess survivors' perceptions of safety and the utility of participating in these interviews. Most participants felt the process was beneficial to their personal lives and criminal justice system engagement by: (a) allowing them to share their stories in more detail, (b) supporting their healing journeys, and (c) helping them feel safer through resource referral. AFI is a promising practice that warrants continued research.

Faculty, Staff and Student Publications

The micromorphology of composite cathodes is known to play a vital role in determining all‐solid‐state battery (ASSB) performance. However, much of our current understanding is derived from empirical observations, lacking a deeper mechanistic foundation. The “rocking chair” concept of battery chemistry requires maintaining charge neutrality, emphasizing the necessity of examining electrode micromorphology from the perspective of conductive networks. This study systematically investigates the microscopic electrochemical impacts of conductive network micromorphology by varying the Li+‐to‐e− channel ratio in cathodes comprising LiNbO3‐coated LiNi0.8Co0.1Mn0.1O2, Li6PS5Cl, and carbon fibers. Utilizing multiscale synchrotron‐based spectro‐microscopy, we unravel that unbalanced Li+ and e− conducting channels intensify charge …

Robust Detection Of Watermarks For Large Language Models Under Human Edits, Xiang Li, Feng Ruan, Huiyuan Wang, Qi Long, Weijie J Su

Faculty, Staff and Student Publications

Watermarking has offered an effective approach to distinguishing text generated by large language models (LLMs) from human-written text. However, the pervasive presence of human edits on LLM-generated text dilutes watermark signals, thereby significantly degrading detection performance of existing methods. In this paper, by modeling human edits through mixture model detection, we introduce a new method in the form of a truncated goodness-of-fit test for detecting watermarked text under human edits, which we refer to as Tr-GoF. We prove that the Tr-GoF test achieves optimality in robust detection of the Gumbel-max watermark in a certain asymptotic regime of substantial text modifications …

Humans with pathogenic variants of the manganese (Mn) transporter gene SLC39A14 exhibit highly elevated brain Mn concentrations and childhood-onset dystonia-parkinsonism. Here we show that Slc39a14-knockout (KO) mice, a preclinical model of the disease with elevated Mn concentrations in the CB, express deficits in physiological tremor implicating cerebellar (CB) dysfunction. Imaging of intracellular Mn in Purkinje cells (PCs) using synchrotron-based X-ray fluorescence microscopy confirmed highly elevated Mn concentrations in the PCs of Slc39a14-KO mice. To determine biological pathways altered in the CB of Slc39a14-KO mice relative to wildtype (WT), we performed RNA sequencing and discovered significant upregulation of pathways and genes …

Epac1 Deletion Attenuates Müller Glial Pathological Activation And Mitigates Retinal Neurodegeneration In Ischemia-Induced Retinopathy, Shuizhen Shi, Fan Xia, Zhongqiao Lu, Erick Palacios, Fang Mei, Massoud Motamedi, Xiaodong Cheng, Hua Liu, Wenbo Zhang

The Brown Foundation: Institute of Molecular Medicine

Introduction: Ischemia-induced retinopathies, such as retinopathy of prematurity and proliferative diabetic retinopathy, are major causes of vision loss. Both pathological neovascularization and neuronal damage contribute to vision impairment in these conditions, yet current therapies primarily target neovascularization and may further compromise neuronal health.

Objectives: Cyclic AMP (cAMP) is a widely recognized second messenger regulating diverse physiological and pathological processes. Exchange protein directly activated by cAMP (Epac) is a recently identified effector of cAMP signaling. This study aimed to investigate the role of Epac1 in ischemia-induced retinopathy and elucidate its underlying mechanisms using a mouse model of oxygen-induced retinopathy (OIR).
