A Phenotypically Robust Model Of Spinal And Bulbar Muscular Atrophy In Drosophila, Kristin Richardson, Medha Sengupta, Alyson Sujkowski, Kozeta Libohova, Autumn C. Harris, Robert Wessells, Diane E. Merry, Sokol V. Todi

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is an X-linked disorder that affects males who inherit the androgen receptor (AR) gene with an abnormal CAG triplet repeat expansion. The resulting protein contains an elongated polyglutamine (polyQ) tract and causes motor neuron degeneration in an androgen-dependent manner. The precise molecular sequelae of SBMA are unclear. To assist with its investigation and the identification of therapeutic options, we report here a new model of SBMA in Drosophila melanogaster. We generated transgenic flies that express the full-length, human AR with a wild-type or pathogenic polyQ repeat. Each transgene is inserted into the same safe …

BACKGROUND: Schwannomas are common peripheral nerve sheath tumors that can cause severe morbidity given their stereotypic intracranial and paraspinal locations. Similar to many solid tumors, schwannomas and other nerve sheath tumors are primarily thought to arise due to aberrant hyperactivation of the RAS growth factor signaling pathway. Here, we sought to further define the molecular pathogenesis of schwannomas.

METHODS: We performed comprehensive genomic profiling on a cohort of 96 human schwannomas, as well as DNA methylation profiling on a subset. Functional studies including RNA sequencing, chromatin immunoprecipitation-DNA sequencing, electrophoretic mobility shift assay, and luciferase reporter assays were performed in a …

Faculty, Staff and Student Publications

We report a case of myeloproliferative neoplasm, not otherwise specified (MPN-NOS)-transformed AML with BCR::JAK2 rearrangement. Chromosomal analysis indicated a simple abnormal karyotype 46,XY,t(7;17)(q21;q24),t(9;22)(p24;q11.2). Fluorescence in situ hybridization (FISH) using a BCR/ABL1/ASS1 probe set suggested a possible BCR rearrangement and a reflex JAK2 breakapart probe indicated JAK2 rearrangement, most likely partnered with BCR. Optical genome mapping (OGM) analysis confirmed BCR::JAK2 derived through an inv(9)(p24p13) after a t(9;22)(p13;q11.2) in this case. Due to the complexity of chromosomal aberrations, disruption and/or rearrangement of other genes such as KIF24::BCR, JAK2::KIF24/UBAP1, and CDK6:SOX9 were also identified by OGM. Although the functionality and clinical …

Benzodioxane-Benzamides As Ftsz Inhibitors: Effects Of Linker's Functionalization On Gram-Positive Antimicrobial Activity, Lorenzo Suigo, William Margolin, Eugenia Ulzurrun, Martina Hrast Rambaher, Carlo Zanotto, Victor Sebastián-Pérez, Nuria E Campillo, Valentina Straniero, Ermanno Valoti

Faculty, Staff and Student Publications

FtsZ is an essential bacterial protein abundantly studied as a novel and promising target for antimicrobials. FtsZ is highly conserved among bacteria and mycobacteria, and it is crucial for the correct outcome of the cell division process, as it is responsible for the division of the parent bacterial cell into two daughter cells. In recent years, the benzodioxane-benzamide class has emerged as very promising and capable of targeting both Gram-positive and Gram-negative FtsZs. In this study, we explored the effect of including a substituent on the ethylenic linker between the two main moieties on the antimicrobial activity and pharmacokinetic properties. …

Rad54l2-Mediated Dna Damage Avoidance Pathway Specifically Preserves Genome Integrity In Response To Topoisomerase 2 Poisons, Huimin Zhang, Yun Xiong, Yilun Sun, Jeong-Min Park, Dan Su, Xu Feng, Sarah Keast, Mengfan Tang, Min Huang, Chao Wang, Mrinal Srivastava, Chang Yang, Dandan Zhu, Zhen Chen, Siting Li, Ling Yin, Yves Pommier, Junjie Chen

Faculty, Staff and Student Publications

Type II topoisomerases (TOP2) form transient TOP2 cleavage complexes (TOP2ccs) during their catalytic cycle to relieve topological stress. TOP2ccs are covalently linked TOP2-DNA intermediates that are reversible but can be trapped by TOP2 poisons. Trapped TOP2ccs block transactions on DNA and generate genotoxic stress, which are the mechanisms of action of TOP2 poisons. How cells avoid TOP2cc accumulation remains largely unknown. In this study, we uncovered RAD54 like 2 (RAD54L2) as a key factor that mediates a TOP2-specific DNA damage avoidance pathway. RAD54L2 deficiency conferred unique sensitivity to treatment with TOP2 poisons. RAD54L2 interacted with TOP2A/TOP2B and ZATT/ZNF451 and promoted …

The Defined Tlr3 Agonist, Nexavant, Exhibits Anti-Cancer Efficacy And Potentiates Anti-Pd-1 Antibody Therapy By Enhancing Immune Cell Infiltration, Seung-Hwan Lee, Young-Ho Choi, Soon Myung Kang, Min-Gyu Lee, Arnaud Debin, Eric Perouzel, Seung-Beom Hong, Dong-Ho Kim

Faculty, Staff and Student Publications

Nexavant was reported as an alternative to the TLR3 agonist of Poly(I:C) and its derivatives. The physicochemical properties, signaling pathways, anti-cancer effects, and mechanisms of Nexavant were investigated. The distinctive characteristics of Nexavant compared to that of Poly(I:C) were demonstrated by precise quantification, enhanced thermostability, and increased resistance to RNase A. Unlike Poly(I:C), which activates TLR3, RIG-I, and MDA5, Nexavant stimulates signaling through TLR3 and RIG-I but not through MDA5. Compared to Poly(I:C), an intratumoral Nexavant treatment led to a unique immune response, immune cell infiltration, and suppression of tumor growth in various animal cancer models. Nexavant therapy outperformed anti-PD-1 …

We evaluated two models to link stressful life events (SLEs) with the psychopathology of schizophrenia spectrum disorders (SSD). We separated SLEs into independent (iSLEs, unlikely influenced by one's behavior) and dependent (dSLEs, likely influenced by one's behavior). Stress-diathesis and stress generation models were evaluated for the relationship between total, i- and d- SLEs and the severity of positive, negative, and depressive symptoms in participants with SSD. Participants with SSD (n = 286; 196 males; age = 37.5 ± 13.5 years) and community controls (n = 121; 83 males; 35.4 ± 13.9 years) completed self-report of lifetime negative total, i- and …

Ewsr1::Atf1 Orchestrates The Clear Cell Sarcoma Transcriptome In Human Tumors And A Mouse Genetic Model, Benjamin B Ozenberger, Li Li, Emily R Wilson, Alexander J Lazar, Jared J Barrott, Kevin B Jones

Faculty, Staff and Student Publications

Clear cell sarcoma (CCS) is a rare, aggressive malignancy that most frequently arises in the soft tissues of the extremities. It is defined and driven by expression of one member of a family of related translocation-generated fusion oncogenes, the most common of which is EWSR1::ATF1. The EWSR1::ATF1 fusion oncoprotein reprograms transcription. However, the binding distribution of EWSR1::ATF1 across the genome and its target genes remain unclear. Here, we interrogated the genomic distribution of V5-tagged EWSR1::ATF1 in tumors it had induced upon expression in mice that also recapitulated the transcriptome of human CCS. ChIP-sequencing of V5-EWSR1::ATF1 identified previously unreported motifs …

Faculty, Staff and Students Publications

BACKGROUND: The primary pathophysiological process of sepsis is to stimulate a massive release of inflammatory mediators to trigger systemic inflammatory response syndrome (SIRS), the major cause of multi-organ dysfunction and death. Like other helminths, Echinococcus granulosus induces host immunomodulation. We sought to determine whether E. granulosus cyst fluid (EgCF) displays a therapeutic effect on sepsis-induced inflammation and tissue damage in a mouse model.

METHODS: The anti-inflammatory effects of EgCF were determined by in vitro culture with bone marrow-derived macrophages (BMDMs) and in vivo treatment of BALB/C mice with cecal ligation and puncture (CLP)-induced sepsis. The macrophage phenotypes were determined by …

Increased Coding Potential Of Bovine Herpesvirus 1, Victoria Jefferson

Theses and Dissertations

Bovine respiratory disease (BRD) costs the cattle industry millions of dollars in costs in treatment and loss every year in the United States. A significant pathogen often contributes to BRD is Bovine Herpesvirus 1 (BoHV-1), a double stranded DNA virus with the ability to establish latency in the trigeminal ganglia and neurons. Primary infection with BoHV-1 results in immunosuppression that increases the risk of secondary bacterial infection and pneumonia. Because herpesviruses infect their hosts for life and can be reactivated in times of stress, BoHV-1 can present a recurring risk of BRD. The following research aims to expand the knowledge …

Is Early Sport Specialization Harming Our Children?, Kendra Dunsford Dpt, Scs, Stc, Preeti Oza Pt, Phd

Pacific Journal of Health

Sports and physical activity in children are healthy and have numerous positive mental and physical health benefits. Recently, there has been a shift away from deliberate play and focusing on specializing in a single sport from a young age. Participating in rigorous training and competition schedules 8 months out of the year for prepubescent athletes has garnered attention from the medical community. It is assumed that this type of early specialization has the potential to cause negative effects, especially in terms of overuse injuries, nutritional deficiencies, poor sleep hygiene, and mental health concerns. While there appears to be a consensus …

Detection Of Suicide Clusters Using Small-Area Geographic Data From The Virginia Violent Death Reporting System, 2010 – 2015, Kurtis M. Anthony, Allison Ertl, Rachel A. Leavitt, Alexander E. Crosby, Ryan M. Diduk-Smith, Kevin A. Matthews

Virginia Journal of Public Health

Introduction: From 1999 to 2020, the suicide rate in Virginia increased from 13.1 to 15.9 per 100,000 persons aged 10 years and older. Few studies have examined spatial patterns of suicide geographies smaller than the county level.

Methods: We analyzed data from suicide decedents aged ≥10 years from 2010 through 2015 in the Virginia Violent Death Reporting System. We identified spatial clusters of high suicide rates using spatially adaptive filtering with standardized mortality ratio (SMR) significantly higher than the state SMR (p < 0.001). We compared demographic characteristics, method of injury, and suicide circumstances of decedents within each cluster to decedents outside any cluster.

Results: We identified 13 high-risk suicide clusters (SMR between 1.7 and 2.0). Suicide decedents in the clusters were …
