Specific Sequence Determinants Of Mir-15/107 Microrna Gene Group Targets, Peter T. Nelson, Wang-Xia Wang, Guogen Mao, Bernard R. Wilfred, Kevin Xie, Mary H. Jennings, Zhen Gao, Xiaowei Wang

Pathology and Laboratory Medicine Faculty Publications

MicroRNAs (miRNAs) target mRNAs in human cells via complex mechanisms that are still incompletely understood. Using anti-Argonaute (anti-AGO) antibody co-immunoprecipitation, followed by microarray analyses and downstream bioinformatics, 'RIP-Chip' experiments enable direct analyses of miRNA targets. RIP-Chip studies (and parallel assessments of total input mRNA) were performed in cultured H4 cells after transfection with miRNAs corresponding to the miR-15/107 gene group (miR-103, miR-107, miR-16 and miR-195), and five control miRNAs. Three biological replicates were run for each condition with a total of 54 separate human Affymetrix Human Gene 1.0 ST array replicates. Computational analyses queried for determinants of miRNA:mRNA binding. The …

Alcoholic Cardiomyopathy: A Review., Anil George, Vincent M Figueredo

Division of Cardiology Faculty Papers

Alcohol abuse can cause cardiomyopathy indistinguishable from other types of dilated nonischemic cardiomyopathy. Most heavy drinkers remain asymptomatic in the earlier stages of disease progression, and many never develop the familiar clinical manifestations that typify heart failure. We review the current thinking on the pathophysiology, clinical characteristics, and treatments available for alcoholic cardiomyopathy. The relationship of alcohol to heart disease is complicated by the fact that in moderation, alcohol has been shown to afford a certain degree of protection against cardiovascular disease.

Chemistry Faculty Research & Creative Works

Background Seborrheic keratoses are the most common skin lesions known to contain small white or yellow structures called milia-like cysts (MLCs). Varied appearances can sometimes make it difficult to differentiate benign lesions from malignant lesions such as melanoma, the deadliest form of skin cancer found in humans. Objective the purpose of this study was to determine the statistical occurrence of MLCs in benign vs. malignant lesions. Methods a medical student with 10 months experience in examining approximately 1000 dermoscopy images and a dermoscopy-naïve observer analyzed contact non-polarized dermoscopy images of 221 malignant melanomas and 175 seborrheic keratoses for presence of …

Systemic Adiponectin Malfunction As A Risk Factor For Cardiovascular Disease., Wayne Bond Lau, Ling Tao, Yajing Wang, Rong Li, Xin L Ma

Department of Emergency Medicine Faculty Papers

Adiponectin (Ad) is an abundant protein hormone regulatory of numerous metabolic processes. The 30 kDa protein originates from adipose tissue, with full-length and globular domain circulatory forms. A collagenous domain within Ad leads to spontaneous self-assemblage into various oligomeric isoforms, including trimers, hexamers, and high-molecular-weight multimers. Two membrane-spanning receptors for Ad have been identified, with differing concentration distribution in various body tissues. The major intracellular pathway activated by Ad includes phosphorylation of AMP-activated protein kinase, which is responsible for many of Ad's metabolic regulatory, anti-inflammatory, vascular protective, and anti-ischemic properties. Additionally, several AMP-activated protein kinase-independent mechanisms responsible for Ad's anti-inflammatory …

Comparison Of Outcomes Of Enteral Feeding Via Nasogastric Versus Gastrostomy Tubes In Post Operative Patients With A Principle Diagnosis Of Squamous Cell Carcinoma Of The Oral Cavity, Zain-Ul-Abedeen Sobani, Shehzad Ghaffar, Beenish Nisar Ahmed

Section of Otolaryngology, Head & Neck Surgery

OBJECTIVES: Squamous cell carcinoma of the oral cavity has a profound impact on a patient's nutritional intake, 40-50% of head and neck cancer patients have a markedly impaired nutritional status at the time of their initial presentation. Studies show that patients who have better nutritional status have fewer complications and a better survival rate. Therefore, enteral nutritional support plays an important part in their management. Due to the lack of relevant data, surgeons help patients make informed decisions regarding their mode of nutritional support and perform gastrostomy or place nasogastric tube depending on the patient's preference. This study addresses the …

Advanced Glycation End Products Accelerate Ischemia/Reperfusion Injury Through Receptor Of Advanced End Product/Nitrative Thioredoxin Inactivation In Cardiac Microvascular Endothelial Cells., Yi Liu, Yanzhuo Ma, Rutao Wang, Chenhai Xia, Rongqing Zhang, Kun Lian, Ronghua Luan, Lu Sun, Lu Yang, Wayne B Lau, Haichang Wang, Ling Tao

Department of Emergency Medicine Faculty Papers

The advanced glycation end products (AGEs) are associated with increased cardiac endothelial injury. However, no causative link has been established between increased AGEs and enhanced endothelial injury after ischemia/reperfusion. More importantly, the molecular mechanisms by which AGEs may increase endothelial injury remain unknown. Adult rat cardiac microvascular endothelial cells (CMECs) were isolated and incubated with AGE-modified bovine serum albumin (BSA) or BSA. After AGE-BSA or BSA preculture, CMECs were subjected to simulated ischemia (SI)/reperfusion (R). AGE-BSA increased SI/R injury as evidenced by enhanced lactate dehydrogenase release and caspase-3 activity. Moreover, AGE-BSA significantly increased SI/R-induced oxidative/nitrative stress in CMECs (as measured …

Reduced Cardioprotective Action Of Adiponectin In High-Fat Diet-Induced Type Ii Diabetic Mice And Its Underlying Mechanisms., Wei Yi, Yang Sun, Erhe Gao, Xufeng Wei, Wayne Bond Lau, Qijun Zheng, Yajing Wang, Yuexing Yuan, Xiaoliang Wang, Ling Tao, Rong Li, Walter Koch, Xin-Liang Ma

Department of Emergency Medicine Faculty Papers

Diabetes exacerbates ischemic heart disease morbidity and mortality via incompletely understood mechanisms. Although adiponectin (APN) reduces myocardial ischemia/reperfusion (MI/R) injury in nondiabetic animals, whether APN's cardioprotective actions are altered in diabetes, a pathologic condition with endogenously reduced APN, has never been investigated. High-fat diet (HD)-induced diabetic mice and normal diet (ND) controls were subjected to MI via coronary artery ligation, and given vehicle or APN globular domain (gAPN, 2 μg/g) 10 min before reperfusion. Compared to ND mice (where gAPN exerted pronounced cardioprotection), HD mice manifested greater MI/R injury, and a tripled gAPN dose was requisite to achieve cardioprotective extent …

Male Gender Preference, Female Gender Disadvantage As Risk Factors For Psychological Morbidity In Pakistani Women Of Childbearing Age - A Life Course Perspective, Farah Qadir, Murad M. Khan Dr., Girmay Medhin, Martin Prince

Department of Psychiatry

Background: In Pakistan, preference for boys over girls is deeply culturally embedded. From birth, many women experience gendered disadvantages, less access to scarce resources, poorer health care, higher child mortality, limited education, less employment outside of the home and circumscribed autonomy. The prevalence of psychological morbidity is exceptionally high among women. We hypothesise that, among women of childbearing age, gender disadvantage is an independent risk factor for psychological morbidity. Methods: A cross-sectional catchment area survey of 525 women aged 18 to 35 years living in Islamabad and Rawalpindi. The effect of gender disadvantage was assessed as a latent variable using …

Use Of Dried-Blood-Spot Samples And In-House Assays To Identify Antiretroviral Drug Resistance In Hiv-Infected Children In Resource-Constrained Settings, Carrie Ziemniak, Yohannes Mengistu, Andrea Ruff, Ya-Hui Chen, Leila Khaki, Abubaker Bedri, Birgitte B. Simen, Paul Palumbo

Dartmouth Scholarship

Monitoring HIV drug resistance is an important component of the World Health Organization's global HIV program. HIV drug resistance testing is optimal with commercially available clinically validated test kits using plasma; however, that type of testing may not be feasible or affordable in resource-constrained settings. HIV genotyping from dried blood spots (DBS) with noncommercial (in-house) assays may facilitate the capture of HIV drug resistance outcomes in resource-constrained settings but has had varying rates of success. With in-house assays for HIV reverse transcriptase, we evaluated the yield of genotyping DBS samples collected from HIV-infected children who were enrolled in two clinical …

Whole-Exome Sequencing Of Dna From Peripheral Blood Mononuclear Cells (Pbmc) And Ebv-Transformed Lymphocytes From The Same Donor., Eric R Londin, Margaret A Keller, Michael R D'Andrea, Kathleen Delgrosso, Adam Ertel, Saul Surrey, Paolo Fortina

Kimmel Cancer Center Faculty Papers

BACKGROUND: The creation of lymphoblastoid cell lines (LCLs) through Epstein-Barr virus (EBV) transformation of B-lymphocytes can result in a valuable biomaterial for cell biology research and a renewable source of DNA. While LCLs have been used extensively in cellular and genetic studies, the process of cell transformation and expansion during culturing may introduce genomic changes that may impact their use and the interpretation of subsequent genetic findings.

RESULTS: We performed whole exome sequencing on a tetrad family using DNA derived from peripheral blood mononuclear cells (PBMCs) and LCLs from each individual. We generated over 4.7 GB of mappable sequence to …

Strain-Dependent Variation In The Early Transcriptional Response To Cns Injury Using A Cortical Explant System, David J. Graber, Brent T. Harris, William F. Hickey

Dartmouth Scholarship

While it is clear that inbred strains of mice have variations in immunological responsiveness, the influence of genetic background following tissue damage in the central nervous system is not fully understood. A cortical explant system was employed as a model for injury to determine whether the immediate transcriptional response to tissue resection revealed differences among three mouse strains. Immunological mRNAs were measured in cerebral cortex from SJL/J, C57BL/6J, and BALB/cJ mice using real time RT-PCR. Freshly isolated cortical tissue and cortical sections incubated in explant medium were examined. Levels of mRNA, normalized to β-actin, were compared using one way analysis …
