Histopathology And Oxidative Stress Analysis Of Concomitant Misoprostol And Celecoxib Administration, Derek E. Murrell, James W. Denham, Sam Harirforoosh

Pharmacy Faculty Articles and Research

Nonsteroidal anti-inflammatory drugs (NSAIDs), non-selective or selective inhibitors of cyclooxygenase (COX-1 and -2), reduce pain and inflammation associated with arthritic diseases. Celecoxib, a COX-2-selective inhibitor providing decreased gastric injury relative to on-selective NSAIDs, is commonly prescribed. Misoprostol, a prostaglandin analog, supplements NSAID-inhibited prostaglandin levels. As concomitant celecoxib and misoprostol administration has been shown to intensify renal adverse effects, this article examined the influence of concomitant administration on hepatic histopathology, oxidative stress, and celecoxib concentration. On days 1 and 2, rat groups (n = 6) were gavaged twice daily (two groups with vehicle and two groups with 100 μg/kg misoprostol). From …

Kaposi Sarcoma Herpesvirus Induces Ho-1 During De Novo Infection Of Endothelial Cells Via Viral Mirna-Dependent And -Independent Mechanisms, Sara Botto, Jennifer Totonchy, Jean K. Gustin, Ashlee V. Moses

Pharmacy Faculty Articles and Research

Kaposi sarcoma (KS) herpesvirus (KSHV) infection of endothelial cells (EC) is associated with strong induction of heme oxygenase-1 (HO-1), a stress-inducible host gene that encodes the rate-limiting enzyme responsible for heme catabolism. KS is an angioproliferative tumor characterized by the proliferation of KSHV-infected spindle cells, and HO-1 is highly expressed in such cells. HO-1 converts the pro-oxidant, proinflammatory heme molecule into metabolites with antioxidant, antiinflammatory, and proliferative activities. Previously published work has shown that KSHV-infected EC in vitro proliferate in response to free heme in a HO-1-dependent manner, thus implicating virus-enhanced HO-1 activity in KS tumorigenesis. The present study investigated …

Gelfand, Younghee Kim, Nagaraj Kerur, Valeria Tarallo, Yoshio Hirano, Shoba Amarnath, Daniel H. Fowler, Marta Radwan, Mark T. Young, Keir Pittman, Paul Kubes, Hitesh Agarwal, Keykavous Parang, David R. Hinton, Ana Bastos-Carvalho, Shengjian Li, Testuhiro Yasuma, Takeshi Mizutani, Reo Yasuma, Charles Wright, Jayakrishna Ambati

Pharmacy Faculty Articles and Research

Nucleoside reverse transcriptase inhibitors (NRTIs) are mainstay therapeutics for HIV that block retrovirus replication. Alu (an endogenous retroelement that also requires reverse transcriptase for its life cycle)–derived RNAs activate P2X7 and the NLRP3 inflammasome to cause cell death of the retinal pigment epithelium in geographic atrophy, a type of age-related macular degeneration. We found that NRTIs inhibit P2X7-mediated NLRP3 inflammasome activation independent of reverse transcriptase inhibition. Multiple approved and clinically relevant NRTIs prevented caspase-1 activation, the effector of the NLRP3 inflammasome, induced by Alu RNA. NRTIs were efficacious in mouse models of geographic atrophy, choroidal neovascularization, graft-versus-host disease, and sterile …

Recently, we reported on the plasma levels of rebamipide in presense or absence of celecoxib or diclofenac in rats [3] using a modified HPLC method of detection developed by Jeoung et al. [4]. To tailor the method towards use in urinary rebamipide extraction and analysis, the following modifications were made:

• To compensate for high concentrations of rebamipide found in urine, a new rebamipide stock solution was prepared …

Structural Similarity Between Β3-Peptides Synthesized From Β3-Homo-Amino Acids Or L-Aspartic Acid Monomers, Sahar Ahmed, Tara Sprules, Kamaljit Kaur

Pharmacy Faculty Articles and Research

Formation of stable secondary structures by oligomers that mimic natural peptides is a key asset for enhanced biological response. Here we show that oligomeric β³‐hexapeptides synthesized from l‐aspartic acid monomers (β³‐peptides 1, 5a, and 6) or homologated β³‐amino acids (β³‐peptide 2), fold into similar stable 14‐helical secondary structures in solution, except that the former form right‐handed 14‐helix and the later form left‐handed 14‐helix. β³‐Peptides from l‐Asp monomers contain an additional amide bond in the side chains that provides opportunities for more hydrogen bonding. However, based on the …

Analysis Of Ligand Bias In Functional Studies Involving The Allosteric Modulation Of G Protein- Coupled Receptors, Frederick J. Ehlert, Michael T. Griffin

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Introduction

The affinity constants of a ligand for active and inactive states of a receptor ultimately determine its capacity to activate downstream signaling events. In this report, we describe a reverse-engineering strategy for estimating these microscopic constants.

Methods

Our approach involves analyzing responses measured downstream in the signaling pathway of a G protein-coupled receptor under conditions of allosteric modulation and reduced receptor expression or partial receptor inactivation. The analysis also yields estimates of the isomerization constant of the unoccupied receptor, the sensitivity constant of the signaling pathway, and the more empirical parameters of the receptor population including the observed affinities …

Mechanism Underlying Ikk Activation Mediated By The Linear Ubiquitin Chain Assembly Complex (Lubac), Hiroaki Fujita, Simin Rahighi, Mariko Akita, Ryuichi Kato, Yoshiteru Sasaki, Soichi Wakatsuki, Kazuhiro Iwai

Pharmacy Faculty Articles and Research

The linear ubiquitin chain assembly complex (LUBAC) ligase, consisting of HOIL-1L, HOIP, and SHARPIN, specifically generates linear polyubiquitin chains. LUBAC-mediated linear polyubiquitination has been implicated in NF-κB activation. NEMO, a component of the IκB kinase (IKK) complex, is a substrate of LUBAC, but the precise molecular mechanism underlying linear chain-mediated NF-κB activation has not been fully elucidated. Here, we demonstrate that linearly polyubiquitinated NEMO activates IKK more potently than unanchored linear chains. In mutational analyses based on the crystal structure of the complex between the HOIP NZF1 and NEMO CC2-LZ domains, which are involved in the HOIP-NEMO interaction, NEMO mutations …

Adverse Effects Of Nonsteroidal Anti-Inflammatory Drugs: An Update Of Gastrointestinal, Cardiovascular, And Renal Complications, Sam Harirforoosh, Waheed Asghar, Fakhreddin Jamali

Pharmacy Faculty Articles and Research

Non-steroidal anti-inflammatory drugs (NSAIDs) are used chronically to reduce pain and inflammation in patients with arthritic conditions, and also acutely as analgesics by many patients. Both therapeutic and adverse effects of NSAIDs are due to inhibition of cyclooxygenase (COX) enzyme. NSAIDs are classified as non-selective and COX-2-selective inhibitors (COXIBS) based on their extent of selectivity for COX inhibition. However, regardless of their COX selectivity, reports are still appearing on the GI side effect of NSAIDs particularly on the lower gastrointestinal (GI) tract and the harmful role of their controlled release formulations. In addition, previously unpublished data stored in the sponsor’s …

Cxcr7 Expression Disrupts Endothelial Cell Homeostasis And Causes Ligand-Dependent Invasion, Jennifer Totonchy, Lisa Clepper, Kevin G. Phillips, Owen J. T. Mccarty, Ashlee V. Moses

Pharmacy Faculty Articles and Research

The homeostatic function of endothelial cells (EC ) is critical for a number of physiological processes including vascular integrity, immunity, and wound healing. Indeed, vascular abnormalities resulting from EC dysfunction contribute to the development and spread of malignancies. The alternative SDF-1/CXCL12 receptor CXCR7 is frequently and specifically highly expressed in tumor-associated vessels. In this study, we investigate whether CXCR7 contributes to vascular dysfunction by specifically examining the effect of CXCR7 expression on EC barrier function and motility. We demonstrate that CXCR7 expression in EC results in redistribution of CD31/PECAM-1 and loss of contact inhibition. Moreover, CXCR7+ EC are deficient in …
