Expression Of Itgb8 In Epicardial Adipose Tissue Is Highly And Directly Correlated With The Severity Of Coronary Atherosclerosis, Nancy Lee, Sarah M. Nicoloro, Juerg R. Straubhaar, Melinda Darrigo, Stanley Tam, Michael P. Czech, Timothy P. Fitzgibbons

Senior Scholars Program

Background: In patients with coronary artery disease (CAD), epicardial adipose tissue (EAT) has been shown to express increased levels of inflammatory cytokines (IL-1β, IL-6, MCP-1, TNFα) and decreased levels of anti-inflammatory and cardioprotective adipokines. However, it is not known whether or not inflammation in EAT is a primary cause or a secondary response to atherosclerosis. In order to better understand this pathophysiology, we tested the hypothesis that expression of certain genes in EAT would correlate with the degree of coronary atherosclerosis.

Purpose: The purpose of this study was to determine whether there is a difference in gene expression in epicardial ...

Stimulation Through Tlr4 Increases Fviii Inhibitor Formation In A Mouse Model Of Hemophilia A, Claire K. Holley

UT GSBS Dissertations and Theses (Open Access)

Hemophilia A is a clotting disorder caused by functional factor VIII (FVIII) deficiency. About 25% of patients treated with therapeutic recombinant FVIII develop antibodies (inhibitors) that render subsequent FVIII treatments ineffective. The immune mechanisms of inhibitor formation are not entirely understood, but circumstantial evidence indicates a role for increased inflammatory response, possibly via stimulation of Toll-like receptors (TLRs), at the time of FVIII immunization. I hypothesized that stimulation through TLR4 in conjunction with FVIII treatments would increase the formation of FVIII inhibitors. To test this hypothesis, FVIII K.O. mice were injected with recombinant human FVIII with or without concomitant ...

Effects Of Intranasally Administered Dnsp-11 On The Central Dopamine System Of Normal And Parkinsonian Fischer 344 Rats, James H. Sonne

Theses and Dissertations--Anatomy and Neurobiology

Due to the blood-brain barrier, delivery of many drugs to the brain has required intracranial surgery which is prone to complication. Here we show that Dopamine Neuron Stimulating Peptide 11 (DNSP-11), following non-invasive intranasal administration, protects dopaminergic neurons from a lesion model of Parkinson’s disease in the rat. A significant and dose-dependent increase in an index of dopamine turnover (the ratio of DOPAC to dopamine) was observed in the striatum of normal young adult Fischer 344 rats by whole-tissue neurochemistry compared to vehicle administered controls.

Among animals challenged with a moderate, unilateral 6-hydroxy-dopamine (6-OHDA) lesion of the substantia nigra ...

Synthesis And Stability Studies Of Prodrugs And Codrugs Of Naltrexone And 6-Β-Naltrexol, Joshua A. Eldridge

Theses and Dissertations--Pharmacy

The present study was divided between two different drug delivery goals, each involving naltrexone (NTX) or its active metabolite, 6-β-naltrexol (NTXOL). First, amino acid esters of NTX and NTXOL were prepared in order to test their candidacy for microneedle-enhanced transdermal delivery. Second, a 3-O-(-)-cytisine-naltrexone (CYT-NTX) codrug was prepared for screening as a potential oral delivery form of NTX and (-)-cytisine (CYT). The amino acid prodrugs were intended for the treatment of alcohol abuse, while the codrug was designed as a single agent for the treatment of alcoholism and tobacco-dependency co-morbidities. One hypothesis of this work was that prodrugs ...

Informationist Support For A Study Of The Role Of Proteases And Peptides In Cancer Pain, Alisa Surkis, Aileen Mccrillis, Richard Mcgowan, Jeffrey Williams, Brian L. Schmidt, Markus Hardt, Neil Rambo

Journal of eScience Librarianship

Two supplements were awarded to the New York University Health Sciences Libraries from the National Library of Medicine's informationist grant program. These supplements funded research support in a number of areas, including data management and bioinformatics, two fields that the library had recently begun to explore. As such, the supplements were of particular value to the library as a testing ground for these newer services.

This paper will discuss a supplement received in support of a grant from the National Institute of Dental and Craniofacial Research (PI: Brian Schmidt) on the role of proteases and peptides in cancer pain ...

Understanding The Structure Of High Density Lipoprotein, Dmitriy Parshakov, Kayla T. Tran

Undergraduate Research Posters 2012

The high-density lipoprotein (HDL), the carrier of ‘good cholesterol’, transports cholesterol from periphery cells to liver for catabolism, a process termed reverse cholesterol transport. In this project we focused on obtaining and characterizing HDL particles.

Regulation Of Lipogenesis By Cyclin-Dependent Kinase 8-Mediated Control Of Srebp-1., Xiaoping Zhao, Daorong Feng, Qun Wang, Arian Abdulla, Xiao-Jun Xie, Jie Zhou, Yan Sun, Ellen S Yang, Lu-Ping Liu, Bhavapriya Vaitheesvaran, Lauren Bridges, Irwin J Kurland, Randy Strich, Jian-Quan Ni, Chenguang Wang, Johan Ericsson, Jeffrey E Pessin, Jun-Yuan Ji, Fajun Yang

Altered lipid metabolism underlies several major human diseases, including obesity and type 2 diabetes. However, lipid metabolism pathophysiology remains poorly understood at the molecular level. Insulin is the primary stimulator of hepatic lipogenesis through activation of the SREBP-1c transcription factor. Here we identified cyclin-dependent kinase 8 (CDK8) and its regulatory partner cyclin C (CycC) as negative regulators of the lipogenic pathway in Drosophila, mammalian hepatocytes, and mouse liver. The inhibitory effect of CDK8 and CycC on de novo lipogenesis was mediated through CDK8 phosphorylation of nuclear SREBP-1c at a conserved threonine residue. Phosphorylation by CDK8 enhanced SREBP-1c ubiquitination and protein ...
