Contrasting Influences Of Drosophila White/Mini-White On Ethanol Sensitivity In Two Different Behavioral Assays, Robin F. Chan, Carol Atkinson Lewellyn, Jacqueline M. Deloyht, Kristyn Sennett, Scarlett Coffman, Matthew Hewitt, Jill C. Bettinger, John M. Warrick, Mike Grotewiel

Human and Molecular Genetics Publications

Background

The fruit fly Drosophila melanogaster has been used extensively to investigate genetic mechanisms of ethanol-related behaviors. Many past studies in flies, including studies from our laboratory, have manipulated gene expression using transposons carrying the genetic-phenotypic marker mini-white, a derivative of the endogenous gene white. Whether the mini-white transgenic marker or the endogenous white gene influence behavioral responses to acute ethanol exposure in flies has not been systematically investigated.

Methods

We manipulated mini-white and white expression via (i) transposons marked with mini-white, (ii) RNAi against mini-white and white and (iii) a null allele of white. We assessed ethanol sensitivity and …

Dietary Regimens Modify Early Onset Of Obesity In Mice Haploinsufficient For Rai1, Joseph T. Alaimo, Natalie H. Hahn, Sureni V. Mullegama, Sarah H. Elsea

Human and Molecular Genetics Publications

Smith-Magenis syndrome is a complex genomic disorder in which a majority of individuals are obese by adolescence. While an interstitial deletion of chromosome 17p11.2 is the leading cause, mutation or deletion of the RAI1 gene alone results in most features of the disorder. Previous studies have shown that heterozygous knockout of Rai1 results in an obese phenotype in mice and that Smith-Magenis syndrome mouse models have a significantly reduced fecundity and an altered transmission pattern of the mutant Rai1 allele, complicating large, extended studies in these models. In this study, we show that breeding C57Bl/6J Rai1+/−mice with FVB/NJ to …

A Placebo-Controlled, Double-Blind, Randomized, Multicenter Study To Assess The Effects Of Dronedarone 400 Mg Twice Daily For 12 Weeks On Atrial Fibrillation Burden In Subjects With Permanent Pacemakers, Michael D. Ezekowitz, Kenneth Ellenbogen , M.D., John P. Dimarco, Karoly Kaszala, Alexander Boddy, Gregory Geba P., Andrew Koren

Human and Molecular Genetics Publications

Purpose

Dronedarone is a benzofuran derivative with a pharmacological profile similar to amiodarone but has a more rapid onset of action and a much shorter half-life (13–19 h). Our goal was to evaluate the efficacy of dronedarone in atrial fibrillation (AF) patients using dual-chamber pacemakers capable of quantifying atrial fibrillation burden.

Methods

Pacemakers were adjusted to optimize AF detection. Patients with AF burden >1 % were randomized to dronedarone 400 mg twice daily (BID) or placebo. Pacemakers were interrogated after 4 and 12 weeks of treatment. The primary endpoint was the change in AF burden from baseline over the 12-week …
