Lifestyle Tools For Men’S Health And Disease Prevention: Well-Being Through Nutrition, Physical Activity, Stress Management, And Connection, Leigh A. Frame

Clinical Research and Leadership Faculty Publications

Mental health is an often-overlooked aspect of overall health and wellness (well-being). Mental illness is increasingly common with 1 in 5 American adults experiencing it annually, and 1 in 20 suffering from a serious mental illness each year [1]. Treatment rates for mental illness are lower in men (37.4%) compared to women (51.2%) [1]. Globally, treatment rates are similar with an estimated cost to the global economy of $1 trillion annually, yet less than 2% of government health expenditure is for mental health worldwide [2]. Despite this, only nine studies have been published specifically targeting men’s mental health through lifestyle …

The Contribution Of Patient Reported Outcome Measures To Shared Decision-Making In Radiation Oncology At A Midwestern Comprehensive Cancer Center, Kellie Bodeker

Doctor of Philosophy in Translational Health Sciences Dissertations

Background. Chronic diseases, such as lung cancer, require a provider-patient relationship developed over time. This relationship fosters shared decision-making (SDM), a collaborative, dynamic information exchange and analysis between provider and patient regarding treatment and desired outcomes. Established benefits to SDM include an improved quality of life and decreased anxiety and depression. Despite established benefits, recent research suggests radiation oncologists are not engaging in SDM. A decision-aid tool utilizing patient reported outcome measures may increase SDM between radiation oncologists and patients with lung cancer. Patient-reported outcome measures, wherein the patient provides direct assessment of their health and quality of life, …

Emerging Cellular And Molecular Strategies For Enhancing Central Nervous System (Cns) Remyelination., Mohammad Abu-Rub, Robert H Miller

Anatomy and Regenerative Biology Faculty Publications

Myelination is critical for the normal functioning of the central nervous system (CNS) in vertebrates. Conditions in which the development of myelin is perturbed result in severely compromised individuals often with shorter lifespans, while loss of myelin in the adult results in a variety of functional deficits. Although some form of spontaneous remyelination often takes place, the repair process as a whole often fails. Several lines of evidence suggest it is feasible to develop strategies that enhance the capacity of the CNS to undergo remyelination and potentially reverse functional deficits. Such strategies include cellular therapies using either neural or mesenchymal …

Tgf-Β Sustains Tumor Progression Through Biochemical And Mechanical Signal Transduction., Robert L Furler, Douglas F Nixon, Christine A Brantner, Anastas Popratiloff, Christel H Uittenbogaart

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Transforming growth factor β (TGF-β) signaling transduces immunosuppressive biochemical and mechanical signals in the tumor microenvironment. In addition to canonical SMAD transcription factor signaling, TGF-β can promote tumor growth and survival by inhibiting proinflammatory signaling and extracellular matrix (ECM) remodeling. In this article, we review how TGF-β activated kinase 1 (TAK1) activation lies at the intersection of proinflammatory signaling by immune receptors and anti-inflammatory signaling by TGF-β receptors. Additionally, we discuss the role of TGF-β in the mechanobiology of cancer. Understanding how TGF-β dampens proinflammatory responses and induces pro-survival mechanical signals throughout cancer development is critical for designing therapeutics that …

Sources And Fates Of Carbamyl Phosphate: A Labile Energy-Rich Molecule With Multiple Facets., Dashuang Shi, Ljubica Caldovic, Mendel Tuchman

Genomics and Precision Medicine Faculty Publications

Carbamyl phosphate (CP) is well-known as an essential intermediate of pyrimidine and arginine/urea biosynthesis. Chemically, CP can be easily synthesized from dihydrogen phosphate and cyanate. Enzymatically, CP can be synthesized using three different classes of enzymes: (1) ATP-grasp fold protein based carbamyl phosphate synthetase (CPS); (2) Amino-acid kinase fold carbamate kinase (CK)-like CPS (anabolic CK or aCK); and (3) Catabolic transcarbamylase. The first class of CPS can be further divided into three different types of CPS as CPS I, CPS II, and CPS III depending on the usage of ammonium or glutamine as its nitrogen source, and whether

The Synergistic Effects Of Saxagliptin And Metformin On Cd34+ Endothelial Progenitor Cells In Early Type 2 Diabetes Patients: A Randomized Clinical Trial., Fiona J Dore, Cleyton C Domingues, Neeki Ahmadi, Nabanita Kundu, Yana Kropotova, Sara Houston, Carol Rouphael, Aytan Mammadova, Linda Witkin, Anamil Khiyami, Richard L Amdur, Sabyasachi Sen

Surgery Faculty Publications

AIMS: Type 2 diabetes is associated with endothelial dysfunction leading to cardiovascular disease. CD34+ endothelial Progenitor Cells (EPCs) are responsible for endothelial repair and neo-angiogenesis and can be used as a cardiovascular disease risk biomarker. This study investigated whether the addition of saxagliptin, a DPP-IV inhibitor, to metformin, may reduce cardiovascular disease risk in addition to improving glycemic control in Type 2 diabetes patients.

METHODS: In 12 week, double-blind, randomized placebo-controlled trial, 42 subjects already taking metformin 1-2 grams/day were randomized to placebo or saxagliptin 5 mg. Subjects aged 40-70 years with diabetes for < 10 years, with no known cardiovascular disease, BMI 25-39.9, HbA1C 6-9% were included. We evaluated EPCs number, function, surface markers and gene expression, in addition to arterial stiffness, blood biochemistries, resting energy expenditure, and body composition parameters. A mixed model regression to examine saxagliptin vs placebo, accounting for within-subject autocorrelation, was done with SAS (p < 0.05).

RESULTS: Although there was no significant …

The Small Rna Complement Of Adult Schistosoma Haematobium., Andreas J Stroehlein, Neil D Young, Pasi K Korhonen, Ross S Hall, Aaron R Jex, Bonnie L Webster, David Rollinson, Paul J Brindley, Robin B Gasser

Microbiology, Immunology, and Tropical Medicine Faculty Publications

BACKGROUND: Blood flukes of the genus Schistosoma cause schistosomiasis-a neglected tropical disease (NTD) that affects more than 200 million people worldwide. Studies of schistosome genomes have improved our understanding of the molecular biology of flatworms, but most of them have focused largely on protein-coding genes. Small non-coding RNAs (sncRNAs) have been explored in selected schistosome species and are suggested to play essential roles in the post-transcriptional regulation of genes, and in modulating flatworm-host interactions. However, genome-wide small RNA data are currently lacking for key schistosomes including Schistosoma haematobium-the causative agent of urogenital schistosomiasis of humans.

METHODOLOGY: MicroRNAs (miRNAs) and other …

Tat Controls Transcriptional Persistence Of Unintegrated Hiv Genome In Primary Human Macrophages., Beatrix Meltzer, Deemah Dabbagh, Jia Guo, Fatah Kashanchi, Mudit Tyagi, Yuntao Wu

Medicine Faculty Publications

In HIV infected macrophages, a large population of viral genomes persists as the unintegrated form (uDNA) that is transcriptionally active. However, how this transcriptional activity is controlled remains unclear. In this report, we investigated whether Tat, the viral transactivator of transcription, is involved in uDNA transcription. We demonstrate that de novo Tat activity is generated from uDNA, and this uDNA-derived Tat (uTat) transactivates the uDNA LTR. In addition, uTat is required for the transcriptional persistence of uDNA that is assembled into repressive episomal minichromatin. In the absence of uTat, uDNA minichromatin is gradually silenced, but remains highly inducible by HDAC …

Amygdala Corticofugal Input Shapes Mitral Cell Responses In The Accessory Olfactory Bulb, Livio Oboti, Eleonora Russo, Tuyen Tran, Daniel Durstewitz, Joshua G. Corbin

Pediatrics Faculty Publications

Interconnections between the olfactory bulb and the amygdala are a major pathway for triggering strong behavioral responses to a variety of odorants. However, while this broad mapping has been established, the patterns of amygdala feedback connectivity and the influence on olfactory circuitry remain unknown. Here, using a combination of neuronal tracing approaches, we dissect the connectivity of a cortical amygdala [posteromedial cortical nucleus (PmCo)] feedback circuit innervating the mouse accessory olfactory bulb. Optogenetic activation of PmCo feedback mainly results in feedforward mitral cell (MC) inhibition through direct excitation of GABAergic granule cells. In addition, LED-driven activity of corticofugal afferents increases …

Genomics and Precision Medicine Faculty Publications

BACKGROUND: Fukutin-related protein (FKRP) mutations are the most common cause of dystroglycanopathies known to cause both limb girdle and congenital muscular dystrophy. The P448Lneo- mouse model has a knock-in mutation in the FKRP gene and develops skeletal, respiratory, and cardiac muscle disease.

METHODS: We studied the natural history of the P448Lneo- mouse model over 9 months and the effects of twice weekly treadmill running. Forelimb and hindlimb grip strength (Columbus Instruments) and overall activity (Omnitech Electronics) assessed skeletal muscle function. Echocardiography was performed using VisualSonics Vevo 770 (FujiFilm VisualSonics). Plethysmography was performed using whole body system (ADInstruments). Histological evaluations included …

Physical Activity Across The Lifespan And Liver Cancer Incidence In The Nih-Aarp Diet And Health Study Cohort., Hannah Arem, Erikka Loftfield, Pedro F Saint-Maurice, Neal D Freedman, Charles E Matthews

Epidemiology Faculty Publications

While liver cancer rates in the United States are increasing, 5-year survival is only 17.6%, underscoring the importance of prevention. Physical activity has been associated with lower risk of developing liver cancer, but most studies assess physical activity only at a single point in time, often in midlife. We utilized physical activity data from 296,661 men and women in the NIH-AARP Diet and Health Study cohort to test whether physical activity patterns over the life course could elucidate the importance of timing of physical activity on liver cancer risk. We used group modeling of longitudinal data to create physical activity …

Reduced Intraepithelial Corneal Nerve Density And Sensitivity Accompany Desiccating Stress And Aging In C57bl/6 Mice, Mary Ann Stepp, Sonali Pal-Ghosh, Gauri Tadvalkar, Alexa Williams, S Pflugfelder, C De Paiva

Anatomy and Regenerative Biology Faculty Publications

Dry Eye disease causes discomfort and pain in millions of patients. Using a mouse acute desiccating stress (DS) model we show that DS induces a reduction in intraepithelial corneal nerve (ICN) density, corneal sensitivity, and apical extension of the intraepithelial nerve terminals (INTs) that branch from the subbasal nerves (SBNs). Topical application of 0.02% Mitomycin C (MMC) or vehicle alone has no impact on the overall loss of axon density due to acute DS. Chronic dry eye, which develops progressively as C57BL/6 mice age, is accompanied by significant loss of the ICNs and corneal sensitivity between 2 and 24 months …

Tumorigenic Proteins Upregulated In The Mycn-Amplified Imr-32 Human Neuroblastoma Cells Promote Proliferation And Migration., Hayat Zaatiti, Jad Abdallah, Zeina Nasr, George Khazen, Anthony Sandler, Tamara J Abou-Antoun

Surgery Faculty Publications

Childhood neuroblastoma is one of the most common types of extra-cranial cancer affecting children with a clinical spectrum ranging from spontaneous regression to malignant and fatal progression. In order to improve the clinical outcomes of children with high-risk neuroblastoma, it is crucial to understand the tumorigenic mechanisms that govern its malignant behaviors. MYCN proto-oncogene, bHLH transcription factor (MYCN) amplification has been implicated in the malignant, treatment-evasive nature of aggressive, high-risk neuroblastoma. In this study, we used a SILAC approach to compare the proteomic signatures of MYCN-amplified IMR-32 and non-MYCN-amplified SK-N-SH human neuroblastoma cells. Tumorigenic proteins, including fatty-acid binding protein 5 …

Impaired Type I Interferon Regulation In The Blood Transcriptome Of Recurrent Asthma Exacerbations., Jose L Gomez, Maria P Diaz, Gustavo Nino, Clemente J Britto

Pediatrics Faculty Publications

BACKGROUND: Asthma exacerbations are an important cause of morbidity in asthma. Respiratory infections are often involved in asthma exacerbations in both children and adults. Some individuals with asthma have increased susceptibility to viral infections and as a result increased rates of asthma exacerbations. We sought to identify a transcriptomic signature in the blood associated with asthma exacerbations triggered by respiratory infections (AETRI) and determine its association with increased risk for asthma exacerbations.

METHODS: We conducted a two-step study using publicly available, previously generated transcriptomic signatures in peripheral blood mononuclear cells (PBMCs) from asthmatics to identify novel markers of increased risk …

Drug Repurposing For Schistosomiasis: Combinations Of Drugs Or Biomolecules., Maria João Gouveia, Paul J Brindley, Fátima Gärtner, José M Correia Da Costa, Nuno Vale

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Schistosomiasis is a major neglected tropical disease. Control of schistosomiasis currently relies on a single drug, praziquantel, and despite its efficacy against the all schistosome species that parasitize humans, it displays some problematic drawbacks and alone is ineffective in counteracting adverse pathologies associated with infection. Moreover, due to the development of the potential emergence of PZQ-resistant strains, the search for additional or alternative antischistosomal drugs have become a public health priority. The current drug discovery for schistosomiasis has been slow and uninspiring. By contrast, repurposing of existing approved drugs may offer a safe, rapid and cost-effective alternative. Combined treatment with …

Sertraline, Paroxetine, And Chlorpromazine Are Rapidly Acting Anthelmintic Drugs Capable Of Clinical Repurposing., Janis C Weeks, William M Roberts, Caitlyn Leasure, Brian M Suzuki, Kristin J Robinson, John M Hawdon, +Several Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Parasitic helminths infect over 1 billion people worldwide, while current treatments rely on a limited arsenal of drugs. To expedite drug discovery, we screened a small-molecule library of compounds with histories of use in human clinical trials for anthelmintic activity against the soil nematode Caenorhabditis elegans. From this screen, we found that the neuromodulatory drugs sertraline, paroxetine, and chlorpromazine kill C. elegans at multiple life stages including embryos, developing larvae and gravid adults. These drugs act rapidly to inhibit C. elegans feeding within minutes of exposure. Sertraline, paroxetine, and chlorpromazine also decrease motility of adult Trichuris muris whipworms, prevent hatching …

Long-Term Exposure Of Fine Particulate Matter Causes Hypertension By Impaired Renal D1 Receptor-Mediated Sodium Excretion Via Upregulation Of G-Protein-Coupled Receptor Kinase Type 4 Expression In Sprague-Dawley Rats., Xi Lu, Zhengmeng Ye, Shuo Zheng, Hongmei Ren, Jing Zeng, Xinquan Wang, Pedro A Jose, Ken Chen, Chunyu Zeng

Medicine Faculty Publications

BACKGROUND: Epidemiological evidence supports an important association between air pollution exposure and hypertension. However, the mechanisms are not clear.

METHODS AND RESULTS: Our present study found that long-term exposure to fine particulate matter (PM2.5) causes hypertension and impairs renal sodium excretion, which might be ascribed to lower D1 receptor expression and higher D1 receptor phosphorylation, accompanied with a higher G-protein-coupled receptor kinase type 4 (GRK4) expression. The in vivo results were confirmed in in vitro studies (ie, PM2.5 increased basal and decreased D1 receptor mediated inhibitory effect on Na+-K+ ATPase activity, decreased D1 receptor expression, and increased D1 receptor phosphorylation …

Neural Correlates Of Taste Reactivity In Autism Spectrum Disorder., Jason A Avery, John E Ingeholm, Sophie Wohltjen, Meghan Collins, Cameron D Riddell, Stephen J Gotts, Lauren Kenworthy, Gregory L Wallace, W Kyle Simmons, Alex Martin

Psychiatry and Behavioral Sciences Faculty Publications

Selective or 'picky' eating habits are common among those with autism spectrum disorder (ASD). These behaviors are often related to aberrant sensory experience in individuals with ASD, including heightened reactivity to food taste and texture. However, very little is known about the neural mechanisms that underlie taste reactivity in ASD. In the present study, food-related neural responses were evaluated in 21 young adult and adolescent males diagnosed with ASD without intellectual disability, and 21 typically-developing (TD) controls. Taste reactivity was assessed using the Adolescent/Adult Sensory Profile, a clinical self-report measure. Functional magnetic resonance imaging was used to evaluate hemodynamic responses …

Aberrant Brain Functional Connectivity In Newborns With Congenital Heart Disease Before Cardiac Surgery, Josepheen De Asis-Cruz, Mary T. Donofrio, Gilbert Vezina, Catherine Limperopoulos

Pediatrics Faculty Publications

Newborns with congenital heart disease (CHD) requiring open heart surgery are at increased risk for neurodevelopmental disabilities. Recent quantitative MRI studies have reported disrupted growth, microstructure, and metabolism in fetuses and newborns with complex CHD. To date, no study has examined whether functional brain connectivity is altered in this high-risk population after birth, before surgery. Our objective was to compare whole-brain functional connectivity of resting state networks in healthy, term newborns (n = 82) and in term neonates with CHD before surgery (n = 30) using graph theory and network-based statistics. We report for the first time intact global network …
