Loss Of Dystrophin Staining In Cardiomyocytes: A Novel Method For Detection Early Myocardial Infarction, Satwat Hashmi, Suhail Al-Salam

Department of Biological & Biomedical Sciences

Myocardial infarction (MI) is the most frequent diagnosis made in majority of sudden death cases subjected to clinical and medicolegal autopsies. When sudden death occurs at a very early stage of MI, traditional macroscopic examination, or histological stains cannot easily detect the myocardial changes. For this reason we propose a new method for detecting MI at an early stage. Murine model of MI was used to induce MI through permanent ligation of left anterior descending branch of left coronary artery. Five groups of C57B6/J mice were used for inducing MI, which includes 20 minutes, 30 minutes, one hour, four hours …

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Reduced cognitive function is common in persons with heart failure (HF). Cardiovascular fitness is a known contributor to cognitive function in many patient populations, but has only been linked to cognition based on estimates of fitness in HF. The current study examined the relationship between fitness as measured by metabolic equivalents (METs) from a standardized stress test and cognition in persons with HF, as well as the validity of office-based predictors of fitness in this population.

Methods

Forty-one HF patients enrolled in cardiac rehabilitation completed a standardized exercise stress test protocol, a brief neuropsychological battery, the 2-minute step …

Loss Of Dok2 Induces Carboplatin Resistance In Ovarian Cancer Via Suppression Of Apoptosis, E. Lum, M. Vigliotti, N. Banerjee, N. Cutter, K. O. Wrzeszczynski, S. Khan, S. Kamalakaran, D. A. Levine, N. Dimitrova, R. Lucito

Journal Articles

Objective. Ovarian cancers are highly heterogeneous and while chemotherapy is the preferred treatment many patients are intrinsically resistant or quickly develop resistance. Furthermore, all tumors that recur ultimately become resistant. Recent evidence suggests that epigenetic deregulation may be a key factor in the onset and maintenance of chemoresistance. We set out to identify epigenetically silenced genes that affect chemoresistance. Methods. The epigenomes of a total of 45 ovarian samples were analyzed to identify epigenetically altered genes that segregate with platinum response, and further filtered with expression data to identify genes that were suppressed. A tissue culture carboplatin resistance screen was …

Naturally occurring human immunity to both schistosomiasis and hookworm infection has been associated with IgE responses against parasite allergen-like proteins. Since the two helminths frequently coinfect the same individuals, there is growing advocacy for their concurrent treatment. However, both helminths are known to exert strong immunomodulatory effects; therefore, coinfected individuals could have immune responses different from those characteristically seen in monoinfected individuals. In this study, we measured changes in IgE, IgG1, and IgG4 responses to schistosome and hookworm antigens, including the allergen-like proteins Schistosoma mansoni tegumental-allergen-like 1 protein (SmTAL1), SmTAL2, and Necator americanus Ancylostoma-secreted protein-2 (Na-ASP-2), following concurrent …

Transcriptional Responses Of In Vivo Praziquantel Exposure In Schistosomes Identifies A Functional Role For Calcium Signalling Pathway Member Camkii, Hong You, Donald P. Mcmanus, Wei Hu, Michael J. Smout, Paul J. Brindley, Geoffrey N. Gobert

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Treatment for clinical schistosomiasis has relied centrally on the broad spectrum anthelmintic praziquantel; however, there is limited information on its mode of action or the molecular response of the parasite. This paper presents a transcriptional and functional approach to defining the molecular responses of schistosomes to praziquantel. Differential gene expression in Schistosoma japonicum was investigated by transcriptome-wide microarray analysis of adult worms perfused from infected mice after 0.5 to 24 hours after oral administration of sub-lethal doses of praziquantel. Genes up-regulated initially in male parasites were associated with “Tegument/Muscle Repair” and “Lipid/Ion Regulation” functions and were followed by “Drug Resistance” …

CGU Faculty Publications and Research

Human immunodeficiency virus (HIV) infection has frequently been associated with vitamin D deficiency as well as chronic inflammatory response. We tested the hypothesis of an independent relationship between serum concentrations of 25-hydroxyvitamin D [25(OH)D] and high-sensitivity C-reactive protein (CRP) in a cohort of HIV-positive people. A cross-sectional survey was conducted among 316 HIV-positive people (181 men and 135 women) aged 16 to 60 years residing in the Kathmandu Valley, Nepal. Serum high-sensitivity CRP concentrations and serum 25(OH)D levels were measured by the latex agglutination nephelometry method and the competitive protein-binding assay, respectively. The relationship between serum CRP concentrations and 25(OH)D …

Two Distinct Categories Of Focal Deletions In Cancer Genomes, M. Rajaram, M. Kato, L. Myeroff, S. D. Markowitz, S. W. Lowe, M. Zhang, A. Krasnitz, R. Lucito, D. Mu, R. S. Powers, +13 Additional Authors

Journal Articles

One of the key questions about genomic alterations in cancer is whether they are functional in the sense of contributing to the selective advantage of tumor cells. The frequency with which an alteration occurs might reflect its ability to increase cancer cell growth, or alternatively, enhanced instability of a locus may increase the frequency with which it is found to be aberrant in tumors, regardless of oncogenic impact. Here we've addressed this on a genome-wide scale for cancer-associated focal deletions, which are known to pinpoint both tumor suppressor genes (tumor suppressors) and unstable loci. Based on DNA copy number analysis …

The Immune Cell Infiltrate Populating Meningiomas Is Composed Of Mature, Antigen-Experienced T And B Cells, L. Fang, D. E. Lowther, M. L. Meizlish, R. C. Anderson, J. N. Bruce, J. N. Stern, G. Yaari, L. Lovato, K. M. Cronk, K. C. O'Connor, +4 Additional Authors

Journal Articles

BACKGROUND: Meningiomas often harbor an immune cell infiltrate that can include substantial numbers of T and B cells. However, their phenotype and characteristics remain undefined. To gain a deeper understanding of the T and B cell repertoire in this tumor, we characterized the immune infiltrate of 28 resected meningiomas representing all grades. METHODS: Immunohistochemistry was used to grossly characterize and enumerate infiltrating lymphocytes. A molecular analysis of the immunoglobulin variable region of tumor-infiltrating B cells was used to characterize their antigen experience. Flow cytometry of fresh tissue homogenate and paired peripheral blood lymphocytes was used to identify T cell phenotypes …

Protein-Tyrosine Phosphatase 1b Antagonized Signaling By Insulin-Like Growth Factor-1 Receptor And Kinase Brk/Ptk6 In Ovarian Cancer Cells, G. F. Fan, G. Lin, R. Lucito, N. K. Tonks

Journal Articles

Ovarian cancer, which is the leading cause of death from gynecological malignancies, is a heterogeneous disease known to be associated with disruption of multiple signaling pathways. Nevertheless, little is known regarding the role of protein phosphatases in the signaling events that underlie the disease; such knowledge will be essential to gain a complete understanding of the etiology of the disease and how to treat it. We have demonstrated that protein-tyrosine phosphatase 1B (PTP1B) was underexpressed in a panel of ovarian carcinoma-derived cell lines, compared with immortalized human ovarian surface epithelial cell lines. Stable restoration of PTP1B in those cancer cell …

Cell Type Difference In Influenza A Viral Mrna Nuclear Export, Sean William Larsen

Theses Digitization Project

The focus of this thesis research was to clarify the role of host Nxf1 in influenza viral mRNA nuclear export. This study aims to define the nuclear mRNA export pathways of influenza viral mRNA. If viral mRNAs are discovered to utilize neither known mRNA nuclear export pathway this would indicate the mRNA exports via undefined mRNA nuclear export pathway. This might be an atypical pathway not utilized by many host mRNAs and thus might reveal novel antiviral target. 293T (Human embryonic kidney cells) and A549 (Human lung epithelial) cells were purchased from ATCC American Tissue Culture Collection.

Generation And Characterization Of Peptide Fusion Proteins, Brianna L. Probasco

Graduate School of Biomedical Sciences Theses and Dissertations

Pathogenic Th17 cells drive progression of many autoimmune diseases. Th17 cells develop from naïve T cells in the immune system after antigen-driven stimulation in a specific cytokine environment. Normally, T cells act to fight off infection, but when not properly controlled, they can cause disease. The cytokine interleukin-23 (IL-23) plays an essential role in the expansion of pathogenic Th17 cells. IL-23 is a heterodimeric protein, composed of a p19 alpha chain and a p40 beta chain. The p40 is also part of IL-12 and binds to the IL-12 receptor beta 1 (IL-12Rβ1) subunit. Thus, it follows that the IL-23 receptor …

Eastern Equine Encephalitis: An Assessment Of Vermont’S Treatment Plan And The Lack Of Preventative Treatment, Lauren E. Bierman

Writing Across the Curriculum

When an avian host and the Culiseta melanura mosquito meet in fresh water hardwood swamps, the Eastern Equine Encephalitis virus (EEE) is spread to the bird community. When that same bird is bitten by a mosquito that feeds on humans, such as the Aedes, Coquillettidia, and Culex species, the EEE virus has found its bridge vector. EEE is a rare disease in humans; the Centers for Disease Control and Prevention (CDC) reported in 2010 that the virus affects an average of 6 people per year (Epidemiology & Geographic Distribution section, para 2). In 2010, blood collected from deer …

Pge 2 Desensitizes Β -Agonist Effect On Human Lung Fibroblast-Mediated Collagen Gel Contraction Through Opregulating Pde4, Qiuhong Fang, Yingmin Ma, Jing Wang, Joel Michalski, Stephen I. Rennard, Xiangde Liu

Journal Articles: Pulmonary & Critical Care Med

In the current study, we investigated the effect of a long-acting β -agonist (salmeterol) and a phosphodiesterase 4 (PDE4) inhibitor (cilomilast) on human lung fibroblast-mediated collagen gel contraction. Higher concentrations of salmeterol (10(-7) and 10(-6) M) inhibited fibroblast-mediated collagen gel contraction. No effect was observed with cilomilast alone (up to 10(-5) M). In the presence of 10(-8) M salmeterol, however, cilomilast could significantly inhibit fibroblast-mediated collagen gel contraction in a concentration-dependent manner (10(-7) ~10(-5) M). Blockade of endogenous PGE2 by indomethacin further potentiated the inhibitory effect of salmeterol on fibroblast-mediated collagen gel contraction, but it did not affect cilomilast's effect. …

The Science Journal of the Lander College of Arts and Sciences

This paper aims to evaluate the option of utilizing Oncolytic Viruses as a viable treatment in fighting cancer. However, due to the broad nature of the subject, a more limited purview is necessary. With that in mind, the focus will be on a few of the more researched ones: Reovirus, Adenovirus, and HSV-1. In each case, we will examine what makes each of these potential options. This will include an examination of each one's tumor-specificity. Cancer and viral physiology will be discussed as necessary to examine the distinct protein expressions in tumor cells, so that the virus's method of battling …

Androgen Receptor-Target Genes In African American Prostate Cancer Disparities, Bi-Dar Wang, Qi Yang, Kristin Ceniccola, Fernando Bianco, Ramez Andrawis, Thomas W. Jarrett, Harold A. Frazier, Steven R. Patierno, Norman H. Lee

Pharmacology and Physiology Faculty Publications

The incidence and mortality rates of prostate cancer (PCa) are higher in African American (AA) compared to Caucasian American (CA) men. To elucidate the molecular mechanisms underlying PCa disparities, we employed an integrative approach combining gene expression profiling and pathway and promoter analyses to investigate differential transcriptomes and deregulated signaling pathways in AA versus CA cancers. A comparison of AA and CA PCa specimens identified 1,188 differentially expressed genes. Interestingly, these transcriptional differences were overrepresented in signaling pathways that converged on the androgen receptor (AR), suggesting that the AR may be a unifying oncogenic theme in AA PCa. Gene promoter …

Factors That Lead To The Immunotherapy Gap In Multiple Sclerosis Testing, Karthika Solai

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Multiple sclerosis is a disease that affects the central nervous system. Most doctors and scientists believe that it is an autoimmune disease. Simply put, the immune system attacks the nerves in a person’s body, thereby causing myelin damage, inflammation, and neurodegeneration. The plaque that then builds up on the nerves is scar tissue created when the wounds made by the immune system heal. It is this plaque that inhibits communication between the axons in the body and causes the symptoms of MS, which includes problems with movement, pain, vision problems, trouble swallowing, fatigue, and heat sensitivity (Baker et al., 2011, …

Two main findings stand out from this study: that communitarian and religious helping values were virtually universal in the study population, and that a majority of the volunteers indicated economic and material interests and …

Preclinical Development Of Phytocannabinoid- And Endocannabinoid- Based Pharmacotherapies For The Treatment Of Ethanol-Induced Neurodegeneration, Daniel J. Liput

Theses and Dissertations--Pharmacy

Excessive ethanol consumption, characteristic of alcohol use disorders (AUDs), is associated with widespread neurodegeneration and cognitive and behavioral impairments that may contribute to the chronic and relapsing nature of alcoholism. Therefore, identifying novel targets that can afford neuroprotection will undoubtedly aid current treatment strategies for AUDs. The cannabinoids have been shown to provide neuroprotection in a variety of preclinical models of neurodegeneration; however minimal data is available regarding the use of cannabinoid-based pharmacotherapies for treating ethanol-induced neurodegeneration. Therefore, the current dissertation examined the overarching hypothesis: the cannabinoids are a therapeutic strategy to afford neuroprotection in the context of ethanol-induced neurodegeneration. …
