Neural Mechanisms Of Respiratory Interoception, Pei-Ying Sarah Chan, Lu-Yuan Lee, Paul W. Davenport

UK CARES Faculty Publications

Respiratory interoception is one of the internal bodily systems that is comprised of different types of somatic and visceral sensations elicited by different patterns of afferent input and respiratory motor drive mediating multiple respiratory modalities. Respiratory interoception is a complex system, having multiple afferents grouped into afferent clusters and projecting into both discriminative and affective centers that are directly related to the behavioral assessment of breathing. The multi-afferent system provides a spectrum of input that result in the ability to interpret the different types of respiratory interceptive sensations. This can result in a response, commonly reported as breathlessness or dyspnea. …

Limbic-Predominant Age-Related Tdp-43 Encephalopathy (Late-Nc): Co-Pathologies And Genetic Risk Factors Provide Clues About Pathogenesis, Peter T. Nelson, David Fardo, Xian Wu, Khine Zin Aung, Matthew D. Cykowski, Yuriko Katsumata

Neurology Faculty Publications

Limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) is detectable at autopsy in more than one- third of people beyond age 85 years and is robustly associated with dementia independent of other pathologies. Although LATE-NC has a large impact on public health, there remain uncertainties about the underlying biologic mechanisms. Here, we review the literature from human studies that may shed light on pathogenetic mechanisms. It is increasingly clear that certain combinations of pathologic changes tend to coexist in aging brains. Although “pure” LATE-NC is not rare, LATE-NC often coexists in the same brains with Alzheimer disease neuropathologic change, brain arteriolosclerosis, …

Comprehensive Assessment Of Tdp‑43 Neuropathology Data In The National Alzheimer’S Coordinating Center Database, Davis C. Woodworth, Katelynn M. Nguyen, Lorena Sordo, Kiana A. Scambray, Elizabeth Head, Claudia H. Kawas, María M. Corrada, Peter T. Nelson, S. Ahmad Sajjadi

Neurology Faculty Publications

TDP-43 proteinopathy is a salient neuropathologic feature in a subset of frontotemporal lobar degeneration (FTLD-TDP), in amyotrophic lateral sclerosis (ALS-TDP), and in limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC), and is associated with hippocampal sclerosis of aging (HS-A). We examined TDP-43-related pathology data in the National Alzheimer’s Coordinating Center (NACC) in two parts: (I) availability of assessments, and (II) associations with clinical diagnoses and other neuropathologies in those with all TDP-43 measures available. Part I: Of 4326 participants with neuropathology data collected using forms that included TDP-43 assessments, data availability was highest for HS-A (97%) and ALS (94%), followed by …

Single-Cell Analysis Identifies Plk1 As A Driver Of Immunosuppressive Tumor Microenvironment In Luad, Yifan Kong, Chaohao Li, Jinpeng Liu, Sai Wu

Markey Cancer Center Faculty Publications

PLK1 (Polo-like kinase 1) plays a critical role in the progression of lung adenocarcinoma (LUAD). Recent studies have unveiled that targeting PLK1 improves the efficacy of immuno- therapy, highlighting its important role in the regulation of tumor immunity. Nevertheless, our understanding of the intricate interplay between PLK1 and the tumor microenvironment (TME) remains incomplete. Here, using genetically engineered mouse model and single- cell RNA-seq analysis, we report that PLK1 promotes an immunosuppressive TME in LUAD, characterized with enhanced M2 polarization of tumor associated macrophages (TAM) and dampened antigen presentation process. Mechanistically, elevated PLK1 coin- cides with increased secretion of CXCL2 …

Androgen Aggravates Aortic Aneurysms Via Suppression Of Pd-1 In Mice, Xufang Mu, Shu Liu, Zhuoran Wang, Kai Jiang, Timothy S. Mcclintock, Arnold Stromberg, Alejandro V. Tezanos, Eugene S. Lee, John A. Curci, Ming C. Gong, Zhenheng Guo

Markey Cancer Center Faculty Publications

Androgen has long been recognized for its pivotal role in the sexual dimorphism of cardiovascular diseases, including aortic aneurysms (AAs), a devastating vascular disease with a higher prevalence and fatality rate in men than in women. However, the mechanism by which androgen mediates AAs is largely unknown. Here, we found that male, not female, mice developed AAs when exposed to aldosterone and high salt (Aldo-salt). We revealed that androgen and androgen receptors (ARs) were crucial for this sexually dimorphic response to Aldo-salt. We identified programmed cell death protein 1 (PD-1), an immune checkpoint, as a key link between androgen and …

Thompson, Jan Cameron, Christine Brown Wilson, Loreena Hill, Paul Tierney, Doris Yu, Debra K. Moser, Karen Spilsbury, Nittaya Srisuk, Jos M. G. A. Schols, Mariëlle Van Der Velden, Gary Mitchell

UK CARES Faculty Publications

Background: Heart failure has an estimated global prevalence of 64.3 million cases, with an average age of a person living with heart failure at 75.2 years. Approximately 20% of residents living in nursing homes (a long-term residential care environment for some individuals) report living with heart failure. Residents living with heart failure in nursing home environments are often frail, have reduced quality of life, higher rates of rehospitalisation and mortality, and greater complications in heart failure management. Further, nursing home staff often lack the knowledge and skills required to provide the necessary care for those living with heart failure. Interventions …

Purpose

Community health needs assessments are required for most state and local public health agencies and non-profit hospitals. Typically based on community health improvement planning models, these assessments encompass overall com- munity health and multiple diseases to inform program planning. National Cancer Institute (NCI)-designated Cancer Centers and community-based cancer-focused programs share the goal of reducing cancer burden in the catchment areas they serve. However, to date, no published models exist to guide cancer-specific needs assessments for a determined geographic area that can inform both public health and research initiatives. The purpose of this article is to outline a cancer needs …

A Mind-Body Intervention To Improve Physical Activity For Patients With Chronic Hip-Related Pain: Protocol For A Mixed Methods Study., Kate N Jochimsen, Kristin R Archer, Robin A Pollini, Robert A Parker, Nomin Enkhtsetseg, Cale A Jacobs, Ana Maria Vranceanu

Psychiatry Faculty Publications

BACKGROUND: Pain and dysfunction persist for most patients following hip-related pain treatment. Additionally, individuals with hip-related pain are typically less physically active than individuals without hip pain, despite evidence that regular physical activity reduces chronic musculoskeletal pain. Poor psychological health is common in patients with hip-related pain and further reinforces low physical activity. Mind-body interventions can improve psychological health and activity levels but have yet to be integrated to provide comprehensive, psychologically informed care for patients with hip-related pain. Thus, we are using the NCCIH intervention development framework to develop Helping Improve PSychological Health (HIPS), a novel, multimodal mind-body intervention …

Protein Oxidation In Aging And Alzheimer’S Disease Brain, Rukhsana Sultana, D. Allan Butterfield

Markey Cancer Center Faculty Publications

Proteins are essential molecules that play crucial roles in maintaining cellular homeostasis and carrying out biological functions such as catalyzing biochemical reactions, structural proteins, immune response, etc. However, proteins also are highly susceptible to damage by reactive oxygen species (ROS) and reactive nitrogen species (RNS). In this review, we summarize the role of protein oxidation in normal aging and Alzheimer’s disease (AD). The major emphasis of this review article is on the carbonylation and nitration of proteins in AD and mild cognitive impairment (MCI). The oxidatively modified proteins showed a strong correlation with the reported changes in brain structure, carbohydrate …

Predicting The Pathway Involvement Of Metabolites Based On Combined Metabolite And Pathway Features, Erik D. Huckvale, Hunter N. B. Moseley

Markey Cancer Center Faculty Publications

A major limitation of most metabolomics datasets is the sparsity of pathway annotations for detected metabolites. It is common for less than half of the identified metabolites in these datasets to have a known metabolic pathway involvement. Trying to address this limitation, machine learning models have been developed to predict the association of a metabolite with a “pathway category”, as defined by a metabolic knowledge base like KEGG. Past models were implemented as a single binary classifier specific to a single pathway category, requiring a set of binary classifiers for generating the predictions for multiple pathway categories. This past approach …

Optimization, Characterization, And Comparison Of Two Luciferase-Expressing Mouse Glioblastoma Models, Louis Rodgers, Julia A. Schulz Pauly, Bryan J. Maloney, Anika M. S. Hartz, Bjoern Bauer

UK CARES Faculty Publications

Glioblastoma (GBM) is the most aggressive brain cancer. To model GBM in research, orthotopic brain tumor models, including syngeneic models like GL261 and genetically engineered mouse models like TRP, are used. In longitudinal studies, tumor growth and the treatment response are typically tracked with in vivo imaging, including bioluminescence imaging (BLI), which is quick, cost-effective, and easily quantifiable. However, BLI requires luciferase-tagged cells, and recent studies indicate that the luciferase gene can elicit an immune response, leading to tumor rejection and experimental variation. We sought to optimize the engraftment of two luciferase-expressing GBM models, GL261 Red-FLuc and TRP-mCherry-FLuc, showing differences …

Influence Of Four Veterinary Antibiotics On Constructed Treatment Wetland Nitrogen Transformation, Matthew Russell, Tiffany L. Messer, Deborah A. Report, Richard L. Smith, Shannon L. Bartelt-Hunt, Daniel D. Snow, Ariel P. Reed

UK CARES Faculty Publications

The use of wetlands as a treatment approach for nitrogen in runoff is a common practice in agroecosystems. However, nitrate is not the sole constituent present in agricultural runoff and other biologically active contaminants have the potential to affect nitrate removal efficiency. In this study, the impacts of the combined effects of four common veterinary antibiotics (chlortetracycline, sulfamethazine, lincomycin, monensin) on nitrate-N treatment efficiency in saturated sediments and wetlands were evaluated in a coupled microcosm/mesocosm scale experiment. Veterinary antibiotics were hypothesized to significantly impact nitrogen speciation (e.g., nitrate and ammonium) and nitrogen uptake and transformation processes (e.g., plant uptake and …

Background: Having an infant in the Neonatal Intensive Care Unit (NICU) can disrupt parent well-being, the transition to parenthood, and the typical trajectories of infant and child health. For lesbian, gay, bisexual, transgender, queer, or other sexual and gender minority identity (LGBTQ+) parents, this stress may be compounded by health disparities and fear of stigma and discrimination; however, research is lacking about LGBTQ+ parents of infants in the NICU. Objectives: The purpose of this integrative review was to better understand the experiences of LGBTQ+ parents of NICU infants, with a focus on experiences of stigma and discrimination, sources of strength …

Plant Model Of Α-Synucleinopathy: Expression Of Α-Synuclein A53t Variant In Hairy Root Cultures Leads To Proteostatic Stress And Dysregulation Of Iron Metabolism, Jasmina Kurepa, Kristen A. Bruce, Greg A. Gerhardt, Jan A. Smalle

Neurology Faculty Publications

Synucleinopathies, typified by Parkinson’s disease (PD), entail the accumulation of α- synuclein (αSyn) aggregates in nerve cells. Various αSyn mutants, including the αSyn A53T variant linked to early-onset PD, increase the propensity for αSyn aggregate formation. In addition to disrupting protein homeostasis and inducing proteostatic stress, the aggregation of αSyn in PD is associated with an imbalance in iron metabolism, which increases the generation of reactive oxygen species and causes oxidative stress. This study explored the impact of αSyn A53T expression in transgenic hairy roots of four medicinal plants (Lobelia cardinalis, Artemisia annua, Salvia miltiorrhiza, and Polygonum multiflorum). In all …

Regulation Of Rorα Stability Through Prmt5-Dependent Symmetric Dimethylation, Gaofeng Xiong, Brynne Obringer, Austen Jones, Elise Horton, Ren Xu

Markey Cancer Center Faculty Publications

Retinoic acid receptor-related orphan receptor alpha (RORα), a candidate tumor suppressor, is prevalently downregulated or lost in malignant breast cancer cells. However, the mechanisms of how RORα expression is regulated in breast epithelial cells remain incompletely understood. Protein arginine N-methyltransferase 5 (PRMT5), a type II methyltransferase catalyzing the symmetric methylation of the amino acid arginine in target proteins, was reported to regulate protein stability. To study whether and how PRMT5 regulates RORα, we examined the direct interaction between RORα and PRMT5 by immunoprecipitation and GST pull-down assays. The results showed that PRMT5 directly bound to RORα, and PRMT5 mainly symmetrically …

A Cautionary Tale About Properly Vetting Datasets Used In Supervised Learning Predicting Metabolic Pathway Involvement, Erik D. Huckvale, Hunter N. B. Moseley

Markey Cancer Center Faculty Publications

The mapping of metabolite-specific data to pathways within cellular metabolism is a major data analysis step needed for biochemical interpretation. A variety of machine learning approaches, particularly deep learning approaches, have been used to predict these metabolite-to-pathway mappings, utilizing a training dataset of known metabolite-to-pathway mappings. A few such training datasets have been derived from the Kyoto Encyclopedia of Genes and Genomes (KEGG). However, several prior published machine learning approaches utilized an erroneous KEGG-derived training dataset that used SMILES molecular representations strings (KEGG-SMILES dataset) and contained a sizable proportion (~26%) duplicate entries. The presence of so many duplicates taint the …

Trilogies: Lessons From 50 Years Facilitating Community-Based Health Assessments And Planning In Appalachia, Bruce Behringer

Journal of Appalachian Health

Involvement of community and organizational groups is fundamental to most public ventures. Most social, health, economic, and educational improvements in Appalachia have been characterized by successfully integrating community input and finding ways to encourage organizational change and collaboration.

Managing group process and related facilitation skills are fundamental competencies for public health professionals and others guiding change efforts. Groups from communities and organizations can get stalled in their deliberations; a facilitator frequently must think quickly to diagnose the situation and propose alternative approaches. Creative and flexible approaches, learned through practice experiences, can blend with theories and frameworks learned in academic preparation …

Overexpression Of Fatty Acid Synthase Upregulates Glutamine–Fructose-6-Phosphate Transaminase 1 And O-Linked N-Acetylglucosamine Transferase To Increase O-Glcnac Protein Glycosylation And Promote Colorectal Cancer Growth, James Drury, Mariah E. Geisen, Josiane Weber Tessmann, Piotr G. Rychahou, Courtney O. Kelson

Markey Cancer Center Faculty Publications

Fatty acid synthesis has been extensively investigated as a therapeutic target in cancers, including colorectal cancer (CRC). Fatty acid synthase (FASN), a key enzyme of de novo lipid synthesis, is significantly upregulated in CRC, and therapeutic approaches of targeting this enzyme are currently being tested in multiple clinical trials. However, the mechanisms behind the pro- oncogenic action of FASN are still not completely understood. Here, for the first time, we show that overexpression of FASN increases the expression of glutamine–fructose-6-phosphate transaminase 1 (GFPT1) and O-linked N-acetylglucosamine transferase (OGT), enzymes involved in hexosamine metabolism, and the level of O-GlcNAcylation in vitro …
