A Synergistic Antiproliferation Effect Of Curcumin And Docosahexaenoic Acid In Sk-Br-3 Breast Cancer Cells: Unique Signaling Not Explained By The Effects Of Either Compound Alone., Jeffrey D. Altenburg, Andrew A. Bieberich, Colin Terry, Kevin A. Harvey, Justin F. Vanhorn, Zhidong Xu, Vincent J. Davisson, Rafat A. Siddiqui

Borch Department of Medicinal Chemistry and Molecular Pharmacology Faculty Publications

Background

Breast cancer is a collection of diseases in which molecular phenotypes can act as both indicators and mediators of therapeutic strategy. Therefore, candidate therapeutics must be assessed in the context of multiple cell lines with known molecular phenotypes. Docosahexaenoic acid (DHA) and curcumin (CCM) are dietary compounds known to antagonize breast cancer cell proliferation. We report that these compounds in combination exert a variable antiproliferative effect across multiple breast cell lines, which is synergistic in SK-BR-3 cells and triggers cell signaling events not predicted by the activity of either compound alone.

Methods

Dose response curves for CCM and DHA …

Inhibition Of Bacterial Growth And Biofilm Production By Metabolites From Hypericum Spp, S.A. Sarkisian, G.E. Henry, K.L. Laplant, D.C. Rowley

Discovery@URI

Biofilm embedded bacterial pathogens such as Staphylococcus spp., Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii are difficult to eradicate and are major sources of bacterial infections. New drugs are needed to combat these pathogens. Hypericum is a plant genus that contains species known to have antimicrobial properties. However, the specific metabolites responsible for the antimicrobial properties are not entirely known, nor have most compounds been tested as inhibitors of biofilm development. The investigation presented here tested seven secondary metabolites isolated from the species Hypericum densiflorum, Hypericum ellipticum, Hypericum prolificum and Hypericum punctatum as inhibitors of bacterial growth and biofilm production. …

Ultrasonic Assisted Layer-By-Layer Assembly For Stable Nanocolloids Of Curcumin And Paclitaxel, Zhiguo Zheng

Doctoral Dissertations

Researchers have been trying to fight cancer with synthesis of new bioactive compounds but many of these novel drugs have low solubility in water and it is difficult to deliver them into a patient's body. One way of solving this particular problem is to use nanoscale drug delivery systems. In this dissertation, we describe using an ultrasonic assisted layer-by-layer encapsulation process to prepare anti-cancer drugs with 50∼200 nm particle size with designed coating to achieve sustained release and target delivery.

Two methods for systematic manufacture of low solubility anti-cancer drug nanoparticles were proposed: I) Top-down approach to breakdown larger drug …

Engineered Nanomaterials: Exposures, Hazards, And Risk Prevention, Robert A. Yokel, Robert C. Macphail

Pharmaceutical Sciences Faculty Publications

Nanotechnology presents the possibility of revolutionizing many aspects of our lives. People in many settings (academic, small and large industrial, and the general public in industrialized nations) are either developing or using engineered nanomaterials (ENMs) or ENM-containing products. However, our understanding of the occupational, health and safety aspects of ENMs is still in its formative stage. A survey of the literature indicates the available information is incomplete, many of the early findings have not been independently verified, and some may have been over-interpreted. This review describes ENMs briefly, their application, the ENM workforce, the major routes of human exposure, some …

Role Of The At2 Receptor In Modulating The Angiotensin Ii Contractile Response Of The Uterine Artery At Mid-Gestation, V. M. Pulgar, H. Yamashiro, J. C. Rose, L. G. Moore

Pharmaceutical Sciences

Introduction: During human pregnancy, circulating concentrations of components of the renin—angiotensin system increase, but pressor refractoriness to angiotensin II (Ang-II) is observed. Given the importance of the Ang-II pressor response in deciding susceptibility to preeclampsia and of the Ang-II system for controlling uterine vasoreactivity, we sought to address the effects of pregnancy on the reactivity of the isolated uterine artery (UA) in mice.

Materials and methods : Blood pressure was measured throughout pregnancy in awake C57BL/6J mice. UA segments were isolated from three groups of animals (non-pregnant, mid [day 12—13] and late [day 18—19] gestation) and studied by wire …

Differential Subcellular Distribution Of Rat Brain Dopamine Receptors And Subtype-Specific Redistribution Induced By Cocaine., Pamela J Voulalas, John Schetz, Ashiwel S Undieh

College of Pharmacy Faculty Papers

We investigated the subcellular distribution of dopamine D(1), D(2) and D(5) receptor subtypes in rat frontal cortex, and examined whether psychostimulant-induced elevation of synaptic dopamine could alter the receptor distribution. Differential detergent solubilization and density gradient centrifugation were used to separate various subcellular fractions, followed by semi-quantitative determination of the relative abundance of specific receptor proteins in each fraction. D(1) receptors were predominantly localized to detergent-resistant membranes, and a portion of these receptors also floated on sucrose gradients. These properties are characteristic of proteins found in lipid rafts and caveolae. D(2) receptors exhibited variable distribution between cytoplasmic, detergent-soluble and detergent-resistant …

Effects Of Androgen Receptor And Androgen On Gene Expression In Prostate Stromal Fibroblasts And Paracrine Signaling To Prostate Cancer Cells, Matthew J. Tanner, R. Charles Welliver, Mengqian Chen, Michael Shtutman, Alejandro Godoy, Gary Smith, Badar M. Mian, Ralph Buttyan

Faculty Publications

The androgen receptor (AR) is expressed in a subset of prostate stromal cells and functional stromal cell AR is required for normal prostate developmental and influences the growth of prostate tumors. Although we are broadly aware of the specifics of the genomic actions of AR in prostate cancer cells, relatively little is known regarding the gene targets of functional AR in prostate stromal cells. Here, we describe a novel human prostate stromal cell model that enabled us to study the effects of AR on gene expression in these cells. The model involves a genetically manipulated variant of immortalized human WPMY-1 …

The Role Of Histone H4 Biotinylation In The Structure Of Nucleosomes., Nina A. Filenko, Carol Kolar, John T. West, S. Abbie Smith, Yousef I. Hassan, Gloria E.O. Borgstahl, Janos Zempleni, Yuri L. Lyubchenko

Journal Articles: Pharmaceutical Sciences

BACKGROUND: Post-translational modifications of histones play important roles in regulating nucleosome structure and gene transcription. It has been shown that biotinylation of histone H4 at lysine-12 in histone H4 (K12Bio-H4) is associated with repression of a number of genes. We hypothesized that biotinylation modifies the physical structure of nucleosomes, and that biotin-induced conformational changes contribute to gene silencing associated with histone biotinylation.

METHODOLOGY/PRINCIPAL FINDINGS: To test this hypothesis we used atomic force microscopy to directly analyze structures of nucleosomes formed with biotin-modified and non-modified H4. The analysis of the AFM images revealed a 13% increase in the length of DNA …
