Analysis of aortic gene expression in ovariectomized ApoE-deficient mice substituted with medroxyprogesterone acetate, norethisterone acetate or placebo

ABSTRACT: Agilent 4x44k Whole Mouse Genome v1 Microarrays were used to analyze aortic transcriptome of mice substituted with medroxyprogesterone acetate, norethisterone acetate or placebo after having been ovariectomized. The aim of this experiment was to detect genes regulated in the gestagen-treated groups as compared to placebo that might be involved in thrombotic events Aortic gene expression was analyzed in ApoE-deficient mice after ovariectomy and 90 days of hormone- or placebo-treatment (medroxyprogesterone acetate or norethisterone acetate) and feeding a high-fat Western-type diet.

Project description:E. coli MG1655 was grown on M9 minimal medium supplemented with 15mM glucose and either 0, 10, 50 or 100 mM acetate. Transcriptomic analysis from exponential growing cells was performed using Agilent microarray A-MEXP-2232. This work was done with the help of students during practicals. Consequently, it is of special interest since we have four biological replicates done over four years and two technical replicates per biological replicate (n=8 per condition). We therefore thank all the INSA-Toulouse students that participated in this project: Leidy Caraballo, Xavier Caron, Pauline Chanut, Sarah Guiziou, Ngoc Thu Hang Pham, Diane Barbay, Céline Ben Hassen, Thomas Cerutti, Cécile Roland, Sarah Srour, Audrey Baylet, Mathilde Beraud, Claudie Bosc, Lilas Courtot, Violaine Dolfo, Anna Kaci, Manon Chevallot-Beroux, Sarah Colom, Fanny Leclerc, Zihan Liao, Grégoire Quinet and Mélina Vaurs.
Project description:This experiment was performed to challenge E. coli response to acetate when its growth rate flux is reduced by 40% with 100 mM methyl α-D-glucopyranoside. Control without inhibition in the exact same conditions was already published on ArrayExpress database (accession number E-MTAB-9086) and could be used for comparison purpose. Here, E. coli BW25113 strain was grown in M9 medium complemented with 15 mM glucose, 100 mM αMG, and 0, 10, 50 or 100 mM sodium acetate. The cells were grown to mid-exponential phase in shake flasks at 37 °C and 200 rpm, in 50 mL of medium before proceeding to RNA extraction and subsequent microarray analysis. Three to four replicates (with two to three biological replicates) were analyzed for each condition.
