Loss Of Peroxiredoxin Iv Protects Mice From Azoxymethane/Dextran Sulfate Sodium-Induced Colorectal Cancer Development, Pratik Thapa, Hong Jiang, Na Ding, Yanning Hao, Aziza Alshahrani, Eun Young Lee, Junichi Fujii, Qiou Wei

Markey Cancer Center Faculty Publications

Peroxiredoxin IV (Prx4), a typical two-cysteine-containing member of the peroxidase family, functions as an antioxidant to maintain cellular redox homeostasis through the reduction of reactive oxygen species (ROS) via cycles of oxidation–reduction reactions. Under oxidative stress, all Prxs including Prx4 are inactivated as their catalytic cysteines undergo hyperoxidation, and hyperoxidized two-cysteine Prxs can be exclusively repaired and revitalized through the reduction cycle catalyzed by sulfiredoxin (Srx). Previously, we showed that Prx4 is a preferred substrate of Srx, and knockout of Srx in mice leads to resistance to azoxymethane/dextran sulfate sodium (AOM/DSS)-induced colon carcinogenesis. To further understand the significance of the …

Objective And Self-Report Outcomes Of Intensive Interdisciplinary Pain Treatment For Youth With Chronic Pain With And Without Functional Neurological Disorder, Kelsey Zaugg, Dustin Wallace, Kayla Friesen, Cara M. Hoffart

Posters

Introduction: Intensive interdisciplinary pain treatment (IIPT) is effective for youth with chronic pain (CP). Many from this population also experience functional neurological disorder (FND). Treatment outcomes for patients with CP and FND during and after IIPT have not been thoroughly examined, and studies utilizing objective physical and occupational therapy measures are particularly lacking. Methods: 301 adolescents (M age=15.34 years, 84.4% girls, CP only: 187, CP and FND: 114) participated in individualized physical, occupational, psychological, and other therapies. Self-report (COPM, functioning) and objective (BOT-2, 6-minute-walk) measures were administered pre-IIPT, post-IIPT, 6-months-post, and one-year-post. Results: Overall, there were strong and statistically significant …

Potential Chemical Risks From Tattoos And Their Relevance To Military Health Policy In The United States, James D. Blando, Blas A. Guigni

Community & Environmental Health Faculty Publications

We summarize and consolidate disparate sources of information about the practice of tattooing and its potential implications for military population health and policy. Each branch of the United States military has policies about tattoos for service members, but these have varied over time and do not cover health protection. The number of veterans receiving disability payments and the cost of those payments has been rising over time; the broad category of skin conditions accounts for 11% of disability claims. Any additional factor, such as tattoos that may increase the occurrence of adverse skin reactions, can substantially impact veteran benefit expenses …

Pakistan Journal of Neurological Sciences (PJNS)

Creutzfeldt-Jakob disease (CJD) is a rare cause of rapidly progressive dementia, it is a neurodegenerative disorder caused by the misfolding of prion proteins in the brain, and misfolded proteins further propagate by causing misfolding of other proteins. It presents with insidious onset of neurobehavioral symptoms that rapidly develop into cognitive and motor decline and uncontrolled seizures. The diagnosis is established with help of clinical signs and symptoms, and using imaging and lab investigations to rule out other treatable causes. Some imaging findings point to the diagnosis of CJD that will be viewed in the cases below. Diagnosis can be augmented …

Markey Cancer Center Faculty Publications

Polychlorinated biphenyls (PCBs) are persistent environmental organic pollutants known to have detrimental health effects. Using a mouse model, we previously demonstrated that PCB126 exposure before and during pregnancy and throughout the perinatal period adversely affected offspring glucose tolerance and/or body composition profiles. The purpose of this study was to investigate the glucose tolerance and body composition of offspring born to dams exposed to PCB126 during the nursing period only. Female ICR mice were bred, and half of the dams were exposed to either vehicle (safflower oil) or 1 μmole PCB126 per kg of body weight via oral gavage on postnatal …

Latexin Regulates Sex Dimorphism In Hematopoiesis Via Gender-Specific Differential Expression Of Microrna 98-3p And Thrombospondin 1, Xiaojing Cui, Cuiping Zhang, Fang Wang, Xinghui Zhao, Shuxia Wang, Jinpeng Liu, Daheng He, Chi Wang, Feng-Chun Yang, Sheng Tong, Ying Liang

Markey Cancer Center Faculty Publications

Hematopoietic stem cells (HSCs) have the ability to self-renew and differentiate to all blood cell types. HSCs and their differentiated progeny show sex/gender differences. The fundamental mechanisms remain largely unexplored. We previously reported that latexin (Lxn) deletion increased HSC survival and repopulation capacity in female mice. Here, we find no differences in HSC function and hematopoiesis in Lxn knockout (Lxn-/- male mice under physiologic and myelosuppressive conditions. We further find that Thbs1, a downstream target gene of Lxn in female HSCs, is repressed in male HSCs. Male-specific high expression of micro- RNA 98-3p (miR98-3p) contributes to Thbs1 suppression in male …

Chronic Environmental Circadian Disruption Increases Atherosclerosis And Dyslipidemia In Female, But Not Male, Apolipoproteine-Deficient Mice, Jeffrey M. Chalfant, Deborah A. Howatt, Victoria B. Johnson, Lisa R. Tannock, Alan Daugherty, Julie S. Pendergast

Saha Cardiovascular Research Center Faculty Publications

Shift work chronically disrupts circadian rhythms and increases the risk of developing cardiovascular disease. However, the mechanisms linking shift work and cardiovascular disease are largely unknown. The goal of this study was to investigate the effects of chronically shifting the light-dark (LD) cycle, which models the disordered exposure to light that may occur during shift work, on atherosclerosis. Atherosclerosis is the progressive accumulation of lipid-filled lesions within the artery wall and is the leading cause of cardiovascular disease. We studied ApolipoproteinE-deficient (ApoE−/−) mice that are a well-established model of atherosclerosis. Male and female ApoE−/− mice were housed in control 12L:12D …

Cervical Spinal Cord Injury Leads To Injury And Altered Metabolism In The Lungs, Emily E. Huffman, Brittany E. Dong, Harrison A. Clarke, Lyndsay E. A. Young, Matthew S. Gentry, Derek B. Allison, Ramon C. Sun, Christopher M. Waters, Warren J. Alilain

Saha Cardiovascular Research Center Faculty Publications

High-cervical spinal cord injury often disrupts respiratory motor pathways and disables breathing in the affected population. Moreover, cervically injured individuals are at risk for developing acute lung injury, which predicts substantial mortality rates. While the correlation between acute lung injury and spinal cord injury has been found in the clinical setting, the field lacks an animal model to interrogate the fundamental biology of this relationship. To begin to address this gap in knowledge, we performed an experimental cervical spinal cord injury (N = 18) alongside sham injury (N = 3) and naïve animals (N = 15) to assess lung injury …

Cardiovascular diseases are a leading cause of mortality and morbidity worldwide. Aberrant thrombosis is a common feature of systemic conditions like diabetes and obesity, and chronic inflammatory diseases like atherosclerosis, cancer, and autoimmune diseases. Upon vascular injury, usually the coagulation system, platelets, and endothelium act in an orchestrated manner to prevent bleeding by forming a clot at the site of the injury. Abnormalities in this process lead to either excessive bleeding or uncontrolled thrombosis/insufficient antithrombotic activity, which translates into vessel occlusion and its sequelae. The FeCl3-induced carotid injury model is a valuable tool in probing how thrombosis initiates and progresses …

Metallic Implant-Related Osteosarcoma, Frawa Mohsin, Mustafa Bin Ali Zubairi, Kulsoom Fatima, Muhammad Asad Diwan

Department of Radiology

Orthopedic metallic prostheses are commonly used in the current practice of orthopedic surgery. Although, biomaterials used in these implants are generally considered to be biologically inert, there have been consequences of foreign body reactions and potential carcinogenesis. Majority of implant-related malignancies are high grade, and develop in bone or soft tissue around the implant site. No clear association has been identified between the biomaterial implanted and the type of sarcoma. We report the case of a 36-year-old male who underwent intramedullary nailing of femur for mid-shaft fracture secondary to trauma and presented with osteogenic sarcoma of femur 14 months later.

Psychosocial Needs Of Pediatric Patients With Cancer Predisposition Syndromes: Standardized Screening Needed, Meredith Ehrhardt, Mirae Fornander, Rachel Moore

Posters

Introduction Cancer predisposition syndromes (CPS; e.g., Li-Fraumeni syndrome, Von Hippel-Lindau syndrome) require routine, standardized medical monitoring with accompanying unique, complex psychosocial needs (e.g., family medical needs). Despite limited research within pediatric populations, emerging literature has begun to support the benefit of routine psychosocial screening in this population. Very few pediatric CPS clinics with dedicated psychosocial care (i.e., psychology) exist in the U.S. and there is currently no standard of care for psychosocial support of CPS patients. This study aims to better understand the psychosocial needs of pediatric CPS patients and support the need for a standardized psychosocial screening protocol among …

A Case Of Hereditary Hemorrhagic Telangiectasia With Juvenile Polyposis Syndrome Associated With Smad4 Mutation, Mai Elzieny, Ashbita Pokharel, Zhenhong Qu

Conference Presentation Abstracts

Background: Hereditary hemorrhagic telangiectasia (HHT), also called Osler–Weber–Rendu syndrome, is an autosomal dominant disease characterized by aberrant blood vessel development throughout the body that results in telangiectasias, arteriovenous malformations (AVMs), and arteriovenous fistulas. Pathogenic variants in multiple genes can cause HHT, with three major disease associated genes, one of which is SMAD4. HHT caused by mutations in SMAD4 is also associated with juvenile polyposis syndrome (JPS), a condition termed JPS-HHT. Histologic features of HHT polyps have not been well characterized other than their non-adenomatous nature. Here we attempt to characterize the histologic features of such polyps in this typical case …

Colon Adenocarcinoma And Birt-Hogg-Dubé Syndrome In A Young Patient: Case Report And Exploration Of Pathologic Implications, Grant W. Jirka, Daniel S. Lefler, Jessica Russo, Babar Bashir

Department of Medical Oncology Faculty Papers

Birt–Hogg–Dubé syndrome (BHD) is an autosomal dominant disorder caused by germline mutations in the folliculin gene (FLCN) that result in the functional loss of the tumor suppressor folliculin. It is classically associated with cutaneous hamartomas, pulmonary cysts with spontaneous pneumothorax, and various renal cancers. In this case, we present a patient initially diagnosed with chromophobe renal cell carcinoma and subsequently found to have colorectal cancer (CRC). The presence of two separate malignancies in a young patient with a strong family history of CRC (father and paternal grandfather) led to genetic testing, which revealed an FLCN c.1177–5_1177-3del mutation, and a diagnosis …

Macrophage-Derived Mlkl In Alcohol-Associated Liver Disease: Regulation Of Phagocytosis, Xiaoqin Wu, Xiude Fan, Megan R Mcmullen, Tatsunori Miyata, Adam Kim, Vai Pathak, Jianguo Wu, Le Z Day, Josiah E Hardesty, Nicole Welch, Jaividhya Dasarathy, Daniela S Allende, Arthur J Mccullough, Jon M Jacobs, Daniel M Rotroff, Srinivasan Dasarathy, Laura E Nagy

Faculty, Staff and Student Publications

BACKGROUND AND AIMS: Mixed lineage kinase domain-like pseudokinase (MLKL), a key terminal effector of necroptosis, also plays a role in intracellular vesicle trafficking that is critical for regulating liver inflammation and injury in alcohol-associated liver disease (ALD). Although receptor interacting protein kinase 3 (Rip3)-/- mice are completely protected from ethanol-induced liver injury, Mlkl-/- mice are only partially protected. Therefore, we hypothesized that cell-specific functions of MLKL may contribute to ethanol-induced injury.

APPROACH AND RESULTS: Bone marrow transplants between Mlkl-/- mice and littermates were conducted to distinguish the role of myeloid versus nonmyeloid Mlkl in the Gao-binge model of ALD. Ethanol-induced …

Immune And Pathologic Responses In Patients With Localized Prostate Cancer Who Received Daratumumab (Anti-Cd38) Or Edicotinib (Csf-1r Inhibitor), Bilal A Siddiqui, Brian F Chapin, Sonali Jindal, Fei Duan, Sreyashi Basu, Shalini S Yadav, Ai-Di Gu, Alexsandra B Espejo, Michelle Kinder, Curtis A Pettaway, John F Ward, Rebecca S S Tidwell, Patricia Troncoso, Paul G Corn, Christopher J Logothetis, Roland Knoblauch, Natalie Hutnick, Marco Gottardis, Charles G Drake, Padmanee Sharma, Sumit K Subudhi

Faculty, Staff and Student Publications

BACKGROUND: The prostate tumor microenvironment (TME) is immunosuppressive, with few effector T cells and enrichment of inhibitory immune populations, leading to limited responses to treatments such as immune checkpoint therapies (ICTs). The immune composition of the prostate TME differs across soft tissue and bone, the most common site of treatment-refractory metastasis. Understanding immunosuppressive mechanisms specific to prostate TMEs will enable rational immunotherapy strategies to generate effective antitumor immune responses. Daratumumab (anti-CD38 antibody) and edicotinib (colony-stimulating factor-1 receptor (CSF-1R) inhibitor) may alter the balance within the prostate TME to promote antitumor immune responses.

HYPOTHESIS: Daratumumab or edicotinib will be safe and …
