Faculty, Staff and Students Publications

While many animals can completely repair injured tissues, the mammalian heart possesses limited regenerative capabilities. Yan and Cigliola et al. show that AAV-mediated, zebrafish-derived tissue regeneration enhancer elements (TREEs) can direct pro-regenerative gene expression in injured cardiac tissue of mice and pigs that turn off following repair.

Agreement Between Patient’S Description Of Abdominal Symptoms Of Possible Upper Gastrointestinal Cancer And General Practitioner Consultation Notes: A Qualitative Analysis Of Video-Recorded Uk Primary Care Consultation Data, Victoria Hardy, Juliet Usher-Smith, Stephanie Archer, Rebecca Barnes, John Lancaster, Margaret Johnson, Matthew Thompson, Jon Emery, Hardeep Singh, Fiona M Walter

Faculty, Staff and Students Publications

Introduction: Abdominal symptoms are common in primary care but infrequently might be due to an upper gastrointestinal (UGI) cancer. Patients' descriptions may differ from medical terminology used by general practitioners (GPs). This may affect how information about abdominal symptoms possibly due to an UGI cancer are documented, creating potential missed opportunities for timely investigation.

Objectives: To explore how abdominal symptoms are communicated during primary care consultations, and identify characteristics of patients' descriptions that underpin variation in the accuracy and completeness with which they are documented in medical records.

Methods and analysis: Primary care consultation video recordings, transcripts and medical records …

Rare Eif4a2 Variants Are Associated With A Neurodevelopmental Disorder Characterized By Intellectual Disability, Hypotonia, And Epilepsy, Maimuna S Paul, Anna R Duncan, Casie A Genetti, Hongling Pan, Adam Jackson, Patricia E Grant, Jiahai Shi, Michele Pinelli, Nicola Brunetti-Pierri, Alexandra Garza-Flores, Dave Shahani, Russell P Saneto, Giuseppe Zampino, Chiara Leoni, Emanuele Agolini, Antonio Novelli, Ulrike Blümlein, Tobias B Haack, Wolfram Heinritz, Eva Matzker, Bader Alhaddad, Rami Abou Jamra, Tobias Bartolomaeus, Saber Alhamdan, Raphael Carapito, Bertrand Isidor, Seiamak Bahram, Alyssa Ritter, Kosuke Izumi, Ben Pode Shakked, Ortal Barel, Bruria Ben Zeev, Amber Begtrup, Deanna Alexis Carere, Sureni V Mullegama, Timothy Blake Palculict, Daniel G Calame, Katharina Schwan, Alicia R P Aycinena, Rasa Traberg, Genomics England Research Consortium, Sofia Douzgou, Harrison Pirt, Naila Ismayilova, Siddharth Banka, Hsiao-Tuan Chao, Pankaj B Agrawal

Eukaryotic initiation factor-4A2 (EIF4A2) is an ATP-dependent RNA helicase and a member of the DEAD-box protein family that recognizes the 5' cap structure of mRNAs, allows mRNA to bind to the ribosome, and plays an important role in microRNA-regulated gene repression. Here, we report on 15 individuals from 14 families presenting with global developmental delay, intellectual disability, hypotonia, epilepsy, and structural brain anomalies, all of whom have extremely rare de novo mono-allelic or inherited bi-allelic variants in EIF4A2. Neurodegeneration was predominantly reported in individuals with bi-allelic variants. Molecular modeling predicts these variants would perturb structural interactions in key protein domains. …

The cellular activation of the NLRP3 inflammasome is spatiotemporally orchestrated by various organelles, but whether lysosomes contribute to this process remains unclear. Here, we show the vital role of the lysosomal membrane-tethered Ragulator complex in NLRP3 inflammasome activation. Deficiency of Lamtor1, an essential component of the Ragulator complex, abrogated NLRP3 inflammasome activation in murine macrophages and human monocytic cells. Myeloid-specific Lamtor1-deficient mice showed marked attenuation of NLRP3-associated inflammatory disease severity, including LPS-induced sepsis, alum-induced peritonitis, and monosodium urate (MSU)-induced arthritis. Mechanistically, Lamtor1 interacted with both NLRP3 and histone deacetylase 6 (HDAC6). HDAC6 enhances the interaction between Lamtor1 and NLRP3, resulting …

UNLABELLED: We evaluated the cancer preventive efficacy of TAK-242, an inhibitor of Toll-like receptor 4 (TLR4), in a mouse model of hepatocellular carcinoma (HCC) occurring in the context of nonalcoholic steatohepatitis (NASH). We also assessed the cellular events associated with the preventive treatment efficacy. We tested oral administration of TAK-242, at clinically relevant but toxicity-reducing doses and scheduling, in mice with hepatocyte-specific deletion of Pten (HepPten-). The optimal dose and oral gavage formulation of TAK-242 were determined to be 30 mg/kg in 5% DMSO in 30% 2-hydroxypropyl-β-cyclodextrin. Daily oral administration of 30 mg/kg TAK-242 over 18 weeks was well tolerated …

Molecular Mechanisms And Future Implications Of Vegf/Vegfr In Cancer Therapy, Sonia A Patel, Monique B Nilsson, Xiuning Le, Tina Cascone, Rakesh K Jain, John V Heymach

Faculty, Staff and Student Publications

Angiogenesis, the sprouting of new blood vessels from existing vessels, is one of six known mechanisms employed by solid tumors to recruit blood vessels necessary for their initiation, growth, and metastatic spread. The vascular network within the tumor facilitates the transport of nutrients, oxygen, and immune cells and is regulated by pro- and anti-angiogenic factors. Nearly four decades ago, VEGF was identified as a critical factor promoting vascular permeability and angiogenesis, followed by identification of VEGF family ligands and their receptors (VEGFR). Since then, over a dozen drugs targeting the VEGF/VEGFR pathway have been approved for approximately 20 solid tumor …

An Intervention Mapping Approach To Developing A Stroke Literacy Video For Recent Stroke Survivors: Development And Usability Study, Mary Carter Denny, Andrea Ancer Leal, Tahani Casameni Montiel, Keona J Wynne, Gabrielle Edquilang, Kim Yen Thi Vu, Farhaan Vahidy, Sean I Savitz, Jennifer Es Beauchamp, Anjail Sharrief

Faculty, Staff and Student Publications

BACKGROUND: Most vascular events after stroke may be prevented by modifying vascular risk factors through medical and behavioral interventions. Stroke literacy-an understanding of stroke symptoms, risk factors, and treatment-likely contributes to vascular risk factor control and in turn stroke recurrence risk. Stroke literacy is the lowest among adults belonging to racial and ethnic minority populations in the United States. Video-based interventions targeting stroke literacy may help acute stroke survivors understand stroke and subsequently reduce the risk of stroke recurrence. However, the failure of prior stroke literacy interventions may be due in part to the fact that the interventions were not …

Faculty, Staff and Student Publications

Osteoporosis is a systemic skeletal disease characterised by low bone mineral density (BMD), degeneration of bone micro-architecture, and impaired bone strength. Cissus quadrangularis (CQ), popularly known as Hadjod (bone setter) in Hindi, is a traditional medicinal herb exhibiting osteoprotective potential in various bone diseases, especially osteoporosis and fractures. However, the cellular mechanisms underpinning its direct effect on bone health through altering the host immune system have never been elucidated. In the present study, we interrogated the osteoprotective and immunoporotic (the osteoprotective potential of CQ via modulating the host immune system) potential of CQ in preventing inflammatory bone loss under oestrogen-deficient …

PURPOSE: Overweight/obese (OW/OB) patients with metastatic melanoma unexpectedly have improved outcomes with immune checkpoint inhibitors (ICI) and BRAF-targeted therapies. The mechanism(s) underlying this association remain unclear, thus we assessed the integrated molecular, metabolic, and immune profile of tumors, as well as gut microbiome features, for associations with patient body mass index (BMI).

EXPERIMENTAL DESIGN: Associations between BMI [normal (NL < 25) or OW/OB (BMI ≥ 25)] and tumor or microbiome characteristics were examined in specimens from 782 patients with metastatic melanoma across 7 cohorts. DNA associations were evaluated in The Cancer Genome Atlas cohort. RNA sequencing from 4 cohorts (n = 357) was batch corrected and gene set enrichment analysis (GSEA) by BMI category was performed. Metabolic profiling was conducted in a subset of patients (x = 36) by LC/MS, and in flow-sorted melanoma tumor cells (x = 37) and patient-derived melanoma cell lines (x = 17) using the Seahorse XF assay. Gut microbiome features were examined in an independent cohort (n = 371).

RESULTS: DNA mutations and copy number variations were not associated with BMI. GSEA demonstrated that tumors from OW/OB patients were metabolically quiescent, with downregulation of oxidative phosphorylation and multiple other metabolic pathways. Direct metabolite analysis and functional metabolic profiling confirmed decreased …

A 15-year-old patient with infective endarteritis had a pulmonary artery vegetation but no ductus arteriosus on echocardiogram. Computed tomography scan revealed a closed ductus that became patent after antibiotics and anticoagulation. Infective endarteritis should be considered in patients with a pulmonary artery vegetation even if no ductus is seen on echocardiogram. (Level of Difficulty: Intermediate.)

Single-Cell Multi-Omics Integration For Unpaired Data By A Siamese Network With Graph-Based Contrastive Loss, Chaozhong Liu, Linhua Wang, Zhandong Liu

Faculty, Staff and Students Publications

BACKGROUND: Single-cell omics technology is rapidly developing to measure the epigenome, genome, and transcriptome across a range of cell types. However, it is still challenging to integrate omics data from different modalities. Here, we propose a variation of the Siamese neural network framework called MinNet, which is trained to integrate multi-omics data on the single-cell resolution by using graph-based contrastive loss.

RESULTS: By training the model and testing it on several benchmark datasets, we showed its accuracy and generalizability in integrating scRNA-seq with scATAC-seq, and scRNA-seq with epitope data. Further evaluation demonstrated our model's unique ability to remove the batch …

Faculty, Staff and Students Publications

Background: The infiltration of inflammatory cells during a kidney injury stimulates myofibroblast activation leading to kidney fibrosis. Fibroblast-specific protein 1 (FSP-1) positive cells have been reported as either myofibroblasts or monocytes during tissue fibrosis. The functions of FSP-1+ cells that are associated with the development of renal fibrosis and the signaling pathways that regulate FSP-1+ cell activation have not been well defined. Methods: In mice with unilateral ureteral obstruction (UUO), we characterized FSP-1+ cells and determined the role of the Notch signaling pathway in the activation of bone marrow-derived FSP-1+ cells during kidney fibrosis. Results: In kidneys from mice with …

Feasibility And Preclinical Efficacy Of Cd7-Unedited Cd7 Car T Cells For T Cell Malignancies, Norihiro Watanabe, Feiyan Mo, Rong Zheng, Royce Ma, Vanesa C Bray, Dayenne G Van Leeuwen, Juntima Sritabal-Ramirez, Hongxiang Hu, Sha Wang, Birju Mehta, Madhuwanti Srinivasan, Lauren D Scherer, Huimin Zhang, Sachin G Thakkar, Laquisa C Hill, Helen E Heslop, Chonghui Cheng, Malcolm K Brenner, Maksim Mamonkin

Faculty, Staff and Students Publications

Chimeric antigen receptor (CAR)-mediated targeting of T lineage antigens for the therapy of blood malignancies is frequently complicated by self-targeting of CAR T cells or their excessive differentiation driven by constant CAR signaling. Expression of CARs targeting CD7, a pan-T cell antigen highly expressed in T cell malignancies and some myeloid leukemias, produces robust fratricide and often requires additional mitigation strategies, such as CD7 gene editing. In this study, we show fratricide of CD7 CAR T cells can be fully prevented using ibrutinib and dasatinib, the pharmacologic inhibitors of key CAR/CD3ζ signaling kinases. Supplementation with ibrutinib and dasatinib rescued the …

The red flour beetle Tribolium castaneum is a resource-rich model for genomic and developmental studies. To extend previous studies on Tribolium eye development, we produced transcriptomes for normal-eyed and eye-depleted heads of pupae and adults to identify differentially transcript-enriched (DE) genes in the visual system. Unexpectedly, cuticle-related genes were the largest functional class in the pupal compound eye DE gene population, indicating differential enrichment in three distinct cuticle components: clear lens facet cuticle, highly melanized cuticle of the ocular diaphragm, which surrounds the Tribolium compound eye for internal fortification, and newly identified facet margins of the tanned cuticle, possibly enhancing …

A Low-Fat/Sucrose Diet Rich In Complex Carbohydrates Reverses High-Fat/Sucrose Diet-Induced Corneal Dysregulation, Prince K Akowuah, Carolina Lema, Rolando E Rumbaut, Alan R Burns

Faculty, Staff and Students Publications

High-fat/sucrose diet feeding in mice causes loss of corneal nerve function and impairs corneal wound healing. While changing to a diet with a low fat/sugar composition and enrichments in complex carbohydrates mitigates the reduction in nerve function, it remains to be determined if it has an effect on corneal wound healing. In this study, 6-week-old C57BL/6 male mice were fed either a normal diet or a high-fat/sucrose diet for 20 weeks. A third group (diet reversal) was placed on a high-fat/sucrose diet for 10 weeks followed by a normal diet for an additional 10 weeks. A central corneal epithelial abrasion …

Uncovering The Role Of Cancer Associated Fibroblasts In Tumor Immunosuppression, Kamal Amirneni, Kavitha Yaddanapudi

Posters-at-the-Capitol

Current advances in cancer immunotherapy are hindered by the immunosuppressive nature of the tumor microenvironment (TME). Cancer-associated fibroblasts (CAFs) are a key component of the TME that contribute to suppressing the immune response. Chemokines and cytokines released by CAFs, such as IL-6, attract circulating monocytes which are converted into myeloid-derived suppressor cells (MDSCs). MDSCs suppress T-cells and natural killer cell proliferation which inactivates the immune response and deters immunotherapy. Both Prostaglandin E₂ (PGE₂) and granulocyte-macrophage colony-stimulating factor (GM-CSF) have been implicated in the CAF immunosuppressive pathway, but a causal link has yet to be established. We hypothesized …

Silicone Gel Sheeting For Treating Keloid Scars, Fan Tian, Qingling Jiang, Junjie Chen, Zhenmi Liu

Faculty, Staff and Student Publications

BACKGROUND: Keloid scarring is one of the most common types of pathological scarring. Keloid scars that fail to heal can affect a person's physical and psychological function by causing pain, pruritus, contractures, and cosmetic disfigurement. Silicone gel sheeting (SGS) is made from medical-grade silicone reinforced with a silicone membrane backing and is one of the most commonly used treatments for keloid scars. However, there is no up-to-date systematic review assessing the effectiveness of SGS for keloid scars. A clear and rigorous review of current evidence is required to guide clinicians, healthcare managers and people with keloid scarring.

Radiation Therapy For Retroperitoneal Sarcomas: A Strass-Ful Situation, Ahsan S Farooqi, B Ashleigh Guadagnolo, Devarati Mitra, Andrew J Bishop

Faculty, Staff and Student Publications

Locoregional recurrence (LRR) is the predominant pattern of relapse and often the cause of death in patients with retroperitoneal sarcomas (RPS). As a result, reducing LRR is a critical objective for RPS patients. However, unlike soft tissue sarcomas (STS) of the superficial trunk and extremity where the benefits of radiation therapy (RT) are well-established, the role of RT in the retroperitoneum remains controversial. Historically, preoperative or postoperative RT, either alone or in combination with intraoperative radiation (IORT), was commonly justified for RPS based on extrapolation from the superficial trunk and extremity STS literature. However, long-awaited results were recently published from …
