Manufactured Aluminum Oxide Nanoparticles Decrease Expression Of Tight Junction Proteins In Brain Vasculature, Lei Chen, Robert A. Yokel, Bernhard Hennig, Michal Toborek

Pharmaceutical Sciences Faculty Publications

Manufactured nanoparticles of aluminum oxide (nano-alumina) have been widely used in the environment; however, their potential toxicity provides a growing concern for human health. The present study focuses on the hypothesis that nano-alumina can affect the blood-brain barrier and induce endothelial toxicity. In the first series of experiments, human brain microvascular endothelial cells (HBMEC) were exposed to alumina and control nanoparticles in dose- and time-responsive manners. Treatment with nano-alumina markedly reduced HBMEC viability, altered mitochondrial potential, increased cellular oxidation, and decreased tight junction protein expression as compared to control nanoparticles. Alterations of tight junction protein levels were prevented by cellular …

Structure- And Ligand-Based Design Of Novel Antimicrobial Agents, Kirk Edward Hevener

Theses and Dissertations (ETD)

The use of computer based techniques in the design of novel therapeutic agents is a rapidly emerging field. Although the drug-design techniques utilized by Computational Medicinal Chemists vary greatly, they can roughly be classified into structure-based and ligand-based approaches. Structure-based methods utilize a solved structure of the design target, protein or DNA, usually obtained by X-ray or NMR methods to design or improve compounds with activity against the target. Ligand-based methods use active compounds with known affinity for a target that may yet be unresolved. These methods include Pharmacophore-based searching for novel active compounds or Quantitative Structure-Activity Relationship (QSAR) studies. …

Synthesis And Evaluation Of Tetramic Acids As Antimicrobial Agents, Jason B. Wilson

Theses and Dissertations (ETD)

As bacterial infectious diseases are a major cause of morbity and mortality throughout the world, and many causative organisms are resistant to currently available antibiotics, the motivation for the development of new drugs is readily apparent. A number of natural products exhibiting antimicrobial activity possess a tetramic acid (2,4-pyrrolidinedione) functional group. As their antibacterial mechanism of action is different from that of many of the currently available antibiotics, these compounds have potential to serve as a basis for a pharmacophore in synthetic compounds. However, toxicity to eukaryotic cells is frequently a problem with currently known tetramic acids. The purpose of …

Sex Differences In Angiotensin Signaling In Bulbospinal Neurons In The Rat Rostral Ventrolateral Medulla, Gang Wang, Teresa A. Milner, Robert C. Speth, Andrea C. Gore, Di Wu, Costantino Iadecola, Joseph P. Pierce

HPD Articles

Sex differences may play a significant role in determining the risk of hypertension. Bulbospinal neurons in the rostral ventrolateral medulla (RVLM) are involved in the tonic regulation of arterial pressure and participate in the central mechanisms of hypertension. Angiotensin II (ANG II) acting on angiotensin type 1 (AT(1)) receptors in RVLM neurons is implicated in the development of hypertension by activating NADPH oxidase and producing reactive oxygen species (ROS). Therefore, we analyzed RVLM bulbospinal neurons to determine whether there are sex differences in: 1) immunolabeling for AT(1) receptors and the key NADPH oxidase subunit p47 using dual-label immunoelectron microscopy, and …

Repression Of The Sumo-Specific Protease Senp1 Induces P53-Dependent Premature Senescence In Normal Human Fibroblasts, Kristin E. Yates, Gregory A. Korbel, Michael Shtutman, Igor Roninson, Daniel Dimaio

Faculty Publications

The proliferative lifespan of normal somatic human cells in culture terminates in a permanent growth-arrested state known as replicative senescence. In this study, we show that RNA interference-mediated repression of the genes encoding the small ubiquitin-related modifier (SUMO)-specific proteases, Senp1, Senp2, and Senp7, induced low passage primary human fibroblasts to senesce rapidly. Following Senp1 repression, we observed a global increase in sumoylated proteins and in the number and size of nuclear SUMO-containing promyelocytic leukemia (PML) bodies. SUMO/PML bodies also increased during replicative senescence. p53 transcriptional activity was enhanced towards known p53 target genes following repression of Senp1, and inhibition of …
