Microrna-Based Biomarkers In Alzheimer’S Disease (Ad), Yuhai Zhao, Vivian Jaber, Peter N. Alexandrov, Andrea Vergallo, Simone Lista, Harald Hampel, Walter J. Lukiw

School of Medicine Faculty Publications

Alzheimer’s disease (AD) is a multifactorial, age-related neurological disease characterized by complex pathophysiological dynamics taking place at multiple biological levels, including molecular, genetic, epigenetic, cellular and large-scale brain networks. These alterations account for multiple pathophysiological mechanisms such as brain protein accumulation, neuroinflammatory/neuro-immune processes, synaptic dysfunction, and neurodegeneration that eventually lead to cognitive and behavioral decline. Alterations in microRNA (miRNA) signaling have been implicated in the epigenetics and molecular genetics of all neurobiological processes associated with AD pathophysiology. These changes encompass altered miRNA abundance, speciation and complexity in anatomical regions of the CNS targeted by the disease, including modified miRNA expression …

Combating Acquired Resistance To Mapk Inhibitors In Melanoma By Targeting Abl1/2-Mediated Reactivation Of Mek/Erk/Myc Signaling, Rakshamani Tripathi, Zulong Liu, Aditi Jain, Anastasia Lyon, Christina Meeks, Dana Richards, Jinpeng Liu, Daheng He, Chi Wang, Marika Nespi, Andrey Rymar, Peng Wang, Melissa Wilson, Rina Plattner

Pharmacology and Nutritional Sciences Faculty Publications

Metastatic melanoma remains an incurable disease for many patients due to the limited success of targeted and immunotherapies. BRAF and MEK inhibitors reduce metastatic burden for patients with melanomas harboring BRAF mutations; however, most eventually relapse due to acquired resistance. Here, we demonstrate that ABL1/2 kinase activities and/or expression are potentiated in cell lines and patient samples following resistance, and ABL1/2 drive BRAF and BRAF/MEK inhibitor resistance by inducing reactivation of MEK/ERK/MYC signaling. Silencing/inhibiting ABL1/2 blocks pathway reactivation, and resensitizes resistant cells to BRAF/MEK inhibitors, whereas expression of constitutively active ABL1/2 is sufficient to promote resistance. Significantly, nilotinib (2nd generation …

Immune Modulation As A Therapeutic Target In An Α-Synuclein Model Of Parkinson’S Disease, Meena Subhashini Subbarayan

USF Tampa Graduate Theses and Dissertations

Parkinson’s disease (PD) is the second most common neurodegenerative disorder affecting about 1.5 million people in the United States with more than 60,000 people diagnosed each year. It is classically characterized by four major symptoms: tremor, postural instability, stiffness in joints, and slow movement (bradykinesia). Pathologically PD is characterized by up to 70% loss of dopaminergic neurons in substantia nigra pars compacta (SNpc) of midbrain and accumulation of presynaptic protein called α-synuclein (α-syn) within dopaminergic neurons that extend to the striatum. This disrupts the nigrostriatal pathway leading to the motor symptoms seen in PD patients. Microglia, the innate immune cells …

Cd123 As A Biomarker In Hematolymphoid Malignancies: Principles Of Detection And Targeted Therapies, Hanadi El Achi, Edouard Dupont, Shilpa Paul, Joseph D Khoury

Faculty, Staff and Student Publications

CD123, the α chain of the interleukin 3 receptor, is a cytokine receptor that is overexpressed in multiple hematolymphoid neoplasms, including acute myeloid leukemia, blastic plasmacytoid dendritic cell neoplasm, acute lymphoblastic leukemia, hairy cell leukemia, and systemic mastocytosis. Importantly, CD123 expression is upregulated in leukemic stem cells relative to non-neoplastic hematopoietic stem cells, which makes it a useful diagnostic and therapeutic biomarker in hematologic malignancies. Varying levels of evidence have shown that CD123-targeted therapy represents a promising therapeutic approach in several cancers. Tagraxofusp, an anti-CD123 antibody conjugated to a diphtheria toxin, has been approved for use in patients with blastic …

Constitutive Genetic Deletion Of Hcn1 Increases Alcohol Preference During Adolescence, Michael C. Salling, Neil L. Harrison

School of Medicine Faculty Publications

The hyperpolarization-activated cyclic nucleotide-gated channel (HCN), which underlies the hyperpolarization-activated cation current (Ih), has diverse roles in regulating neuronal excitability across cell types and brain regions. Recently, HCN channels have been implicated in preclinical models of substance abuse including alcohol. In the prefrontal cortex of rodents, HCN expression and Ih magnitude are developmentally regulated during adolescence and may be vulnerable to alcohol’s effects. In mice, binge alcohol consumption during the adolescent period results in a sustained reduction in Ih that coincides with increased alcohol consumption in adulthood, yet the direct role HCN channels have on alcohol consumption are unknown. Here, …

Characterization Of The 5′-Flanking Region Of The Human And Mouse Chac1 Genes, Yuki Nomura, Charity F. Sylvester, Lisa O. Nguyen, Mahmoud Kandeel, Yoko Hirata, Imran N. Mungrue, Kentaro Oh-Hashi

School of Medicine Faculty Publications

The Unfolded Protein Response pathway is a conserved signaling mechanism having important roles in cellular physiology and is perturbed accompanying disease. We previously identified the novel UPR target gene CHAC1, a direct target of ATF4, downstream of PERK-EIF2A and activated by the UPR pathway. CHAC1 enzyme directs catalysis of γ-linked glutamate bonds within specific molecular targets. CHAC1 is the first enzyme characterized that can catalyze intracellular glutathione degradation in eukaryotes, having implications for regulation of oxidative stress. DDIT3 (CHOP) is a terminal UPR transcription factor, regulated by ATF4 and an output promoting cell death signaling. Herein we examine the relationship …

Computational Modeling Analysis Of Generation Of Reactive Oxygen Species By Mitochondrial Assembled And Disintegrated Complex Ii., Nikolay I. Markevich, Lubov N. Markevich, Jan B. Hoek

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Reactive oxygen species (ROS) function as critical mediators in a broad range of cellular signaling processes. The mitochondrial electron transport chain is one of the major contributors to ROS formation in most cells. Increasing evidence indicates that the respiratory Complex II (CII) can be the predominant ROS generator under certain conditions. A computational, mechanistic model of electron transfer and ROS formation in CII was developed in the present study to facilitate quantitative analysis of mitochondrial ROS production. The model was calibrated by fitting the computer simulated results to experimental data obtained on submitochondrial particles (SMP) prepared from bovine and rat …

Reactive oxygen species have been involved in the pathogenesis of rheumatoid arthritis (RA). Our goal was to determine the effects of selectively scavenging superoxide (O2•−) and hydroxyl radicals with antioxidant nanoparticles, called poly(ethylene glycol)-functionalized hydrophilic carbon clusters (PEG-HCCs), on the pathogenic functions of fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis (RA) and on the progression of an animal model of RA. We used human FLS from patients with RA to determine PEG-HCC internalization and effects on FLS cytotoxicity, invasiveness, proliferation, and production of proteases. We used the pristane-induced arthritis (PIA) rat model of RA to assess the benefits of …

Tumor Somatic Mutations Also Existing As Germline Polymorphisms May Help To Identify Functional Snps From Genome-Wide Association Studies, Ivan P Gorlov, Xiangjun Xia, Spiridon Tsavachidis, Olga Y Gorlova, Christopher I Amos

Faculty, Staff and Students Publications

We hypothesized that a joint analysis of cancer risk-associated single-nucleotide polymorphism (SNP) and somatic mutations in tumor samples can predict functional and potentially causal SNPs from GWASs. We used mutations reported in the Catalog of Somatic Mutations in Cancer (COSMIC). Confirmed somatic mutations were subdivided into two groups: (1) mutations reported as SNPs, which we call mutational/SNPs and (2) somatic mutations that are not reported as SNPs, which we call mutational/noSNPs. It is generally accepted that the number of times a somatic mutation is reported in COSMIC correlates with its selective advantage to tumors, with more frequently reported mutations being …

Inherited Causes Of Clonal Haematopoiesis In 97,691 Whole Genomes, Alexander G. Bick, Joshua S. Weinstock, Satish K. Nandakumar, Charles P. Fulco, Erik L. Bao, Seyedeh M. Zekavat, Mindy D. Szeto, Juan M. Peralta, Joanne E. Curran, John Blangero

School of Medicine Publications

Age is the dominant risk factor for most chronic human diseases, but the mechanisms through which ageing confers this risk are largely unknown1. The age-related acquisition of somatic mutations that lead to clonal expansion in regenerating haematopoietic stem cell populations has recently been associated with both haematological cancer2,3,4 and coronary heart disease5—this phenomenon is termed clonal haematopoiesis of indeterminate potential (CHIP)6. Simultaneous analyses of germline and somatic whole-genome sequences provide the opportunity to identify root causes of CHIP. Here we analyse high-coverage whole-genome sequences from 97,691 participants of diverse …

Distribution Of Microglial Phenotypes As A Function Of Age And Alzheimer's Disease Neuropathology In The Brains Of People With Down Syndrome, Alessandra C. Martini, Alex M. Helman, Katie L. Mccarty, Ira T. Lott, Eric Doran, Frederick A. Schmitt, Elizabeth Head

Sanders-Brown Center on Aging Faculty Publications

Introduction: Microglial cells play an important role in the development of Alzheimer's disease (AD). People with Down syndrome (DS) inevitably develop AD neuropathology (DSAD) by 40 years of age. We characterized the distribution of different microglial phenotypes in the brains of people with DS and DSAD.

Methods: Autopsy tissue from the posterior cingulate cortex (PCC) from people with DS, DSAD, and neurotypical controls was immunostained with the microglial marker Iba1 to assess five microglia morphological types.

Results: Individuals with DS have more hypertrophic microglial cells in their white matter. In the gray matter, individuals with DSAD had significantly fewer ramified …

Mutations in the skeletal muscle Ca2+ release channel, the type 1 ryanodine receptor (RYR1), cause malignant hyperthermia susceptibility (MHS) and a life-threatening sensitivity to heat, which is most severe in children. Mice with an MHS-associated mutation in Ryr1 (Y524S, YS) display lethal muscle contractures in response to heat. Here we show that the heat response in the YS mice is exacerbated by brown fat adaptive thermogenesis. In addition, the YS mice have more brown adipose tissue thermogenic capacity than their littermate controls. Blood lactate levels are elevated in both heat-sensitive MHS patients with RYR1 mutations and YS mice due to …

Steered Molecular Dynamic Simulations Reveal Marfan Syndrome Mutations Disrupt Fibrillin-1 Cbegf Domain Mechanosensitive Balcium Binding, Stephen J. Haller, Adrian E. Roitberg, Andrew T. Dudley

Journal Articles: Genetics, Cell Biology & Anatomy

Marfan syndrome (MFS) is a highly variable genetic connective tissue disorder caused by mutations in the calcium binding extracellular matrix glycoprotein fibrillin-1. Patients with the most severe form of MFS (neonatal MFS; nMFS) tend to have mutations that cluster in an internal region of fibrillin-1 called the neonatal region. This region is predominantly composed of eight calcium-binding epidermal growth factor-like (cbEGF) domains, each of which binds one calcium ion and is stabilized by three highly conserved disulfide bonds. Crucially, calcium plays a fundamental role in stabilizing cbEGF domains. Perturbed calcium binding caused by cbEGF domain mutations is thus thought to …

Overcoming Barriers For Sirna Therapeutics: From Bench To Bedside, Muhammad Imran Sajid, Muhammad Moazzam, Shun Kato, Kayley Yeseom Cho, Rakesh Kumar Tiwari

Pharmacy Faculty Articles and Research

The RNA interference (RNAi) pathway possesses immense potential in silencing any gene in human cells. Small interfering RNA (siRNA) can efficiently trigger RNAi silencing of specific genes. FDA Approval of siRNA therapeutics in recent years garnered a new hope in siRNA therapeutics. However, their therapeutic use is limited by several challenges. siRNAs, being negatively charged, are membrane-impermeable and highly unstable in the systemic circulation. In this review, we have comprehensively discussed the extracellular barriers, including enzymatic degradation of siRNAs by serum endonucleases and RNAases, rapid renal clearance, membrane impermeability, and activation of the immune system. Besides, we have thoroughly described …

BACKGROUND: In resource-limited countries, risk stratification can be used to optimize colorectal cancer screening. Few prospective risk prediction models exist for advanced neoplasia (AN) in true average-risk individuals.

AIM: To create and internally validate a risk prediction model for detection of AN in average-risk individuals.

METHODS: Prospective study of asymptomatic individuals undergoing first screening colonoscopy. Detailed characteristics including diet, exercise and medications were collected. Multivariate logistic regression was used to elucidate risk factors for AN (adenoma ≥1 cm, villous histology, high-grade dysplasia or carcinoma). The model was validated through bootstrapping, and discrimination and calibration of the model were assessed.

A growing body of evidence shows that altering the inflammatory response by alternative macrophage polarization is protective against complications related to acute myocardial infarction (MI). We have previously shown that oral azithromycin (AZM), initiated prior to MI, reduces inflammation and its negative sequelae on the myocardium. Here, we investigated the immunomodulatory role of a liposomal AZM formulation (L-AZM) in a clinically relevant model to enhance its therapeutic potency and avoid off-target effects. L-AZM (40 or 10 mg/kg, IV) was administered immediately post-MI and compared to free AZM (F-AZM). L-AZM reduced cardiac toxicity and associated mortality by 50% in mice. We …

We injected the tracer cholera toxin B subunit (CTb) into area 18 of adult ferrets to visualize the distribution and pattern of retrogradely labeled …

Exosomes Secreted Under Hypoxia Enhance Stemness In Ewing's Sarcoma Through Mir-210 Delivery, Matthew J. Kling, Nagendra K. Chaturvedi, Varun Kesherwani, Don W. Coulter, Timothy R. Mcguire, J. Graham Sharp, Shantaram S. Joshi

Journal Articles: Genetics, Cell Biology & Anatomy

Intercellular communication between tumor cells within the hypoxic microenvironment promote aggressiveness and poor patient prognoses for reasons that remain unclear. Here we show that hypoxic Ewing's sarcoma (EWS) cells release exosomes that promote sphere formation, a stem-like phenotype, in EWS cells by enhancing survival. Analysis of the hypoxic exosomal miRNA cargo identified a HIF-1α regulated miRNA, miR-210, as a potential mediator of sphere formation in cells exposed to hypoxic exosomes. Knockdown of HIF-1α in hypoxic EWS cells led to decreased exosomal miR-210 levels and reduced the capacity of hypoxic exosomes to form spheres. Inhibition of miR-210 in hypoxic spheres attenuated …

Évaluation De L'Exposition Des Thanatopracteurs Aux Bioaérosols Et Appréciation Du Risque Sur Leur Santé, Geneviève Marchand, Loïc Wingert, Stéphane Hallé, Maximilien Debia

Rapports de recherche scientifique

Plusieurs manipulations réalisées sur les corps des défunts par les thanatopracteurs produisent des bioaérosols qui peuvent contenir des agents pathogènes infectieux. La ventilation générale est souvent le seul moyen utilisé dans les laboratoires de thanatopraxie pour maîtriser les bioaérosols. Toutefois, il n’y a pas de recommandations précises pour sa mise en application. De plus, peu d'études abordent les expositions professionnelles aux bioaérosols dans le domaine de la thanatopraxie tant quantitativement (niveau d’exposition) que qualitativement (identification et classification selon les groupes de risque). L’objectif de cette étude était d’évaluer l’exposition des thanatopracteurs aux bioaérosols afin d’apprécier les risques potentiels sur leur …

A common neurological disease that can result from multiple concussions is Chronic Traumatic Encephalopathy (CTE), characterized by symptoms such as severe depression, anxiety, confusion, and aggression; amongst others.1 On the cellular level, CTE is classified by a unique pathway that leads to the hyperphosphorylation of tau protein and subsequent clumping of tau-containing neurofibrillary tangles …

Can Viruses Cause Lupus?, Stephen I. Reeder

Selected Honors Theses

Like so many autoimmune diseases, the exact cause of systemic lupus erythematosus (SLE) remains unknown. Evidence points to both genetics and environment playing roles in the onset of the disease, but neither acts independent of the other. Genetics are the easier of the two to study with recent advances in the field making it easier to isolate genes shared by individuals with the disease. However, genetic studies reveal that there is almost certainly an environmental component to the development of SLE. The underlying pathology and existing research on environmental contributors to the development of SLE suggest that viruses could potentially …

The Effects Of E-Vapor On The Pathogenesis Of Rheumatoid Arthritis Mouse Models And Potential Implications For Future Generations, Christiana Daas

Rheumatoid arthritis is the most prevalent autoimmune disease. Rheumatoid arthritis (RA) has no cure, and the direct cause of the disease is still unknown. The two leading hypotheses concerning its etiology are based on the effects of HLA-DRB1 gene expression, and cigarette smoke. Conjunctively, the use of vaping devices amongst adolescents has increased significantly since introduced in 2007. There is no long-term data on the effects of e-vapor and its aerosols on bodily health. Cigarette smoke is the most noteworthy environmental factor contributing to RA therefore the question is raised as to whether or not vaping relates to rheumatoid arthritis …
