Saccharomyces cerevisiae response to Octanoic and Decanoic acids

ABSTRACT: In this study, we present an investigation of the yeast response to the exposure to octanoic and decanoic acids, two major fermentation inhibitors. Aerobically grown cells of Saccharomyces cerevisiae U13 wine strain have been exposed to 0,05 mM of octanoic and decanoic acid. We have compared the variations of expression induced by the acid challenges in comparison to a reference non trated modality, as well as the two acid responses. The transcriptome analysis is build in a triangular design in which the RNA extracted from three modalities : reference (non treated cells) , cells exposed to octanoic acid, and cells exposed to decanoic acid are compared.

Transcriptomic analysis of carboxylic acid challenge in Escherichia coli: beyond membrane damage

Project description:Carboxylic acids are an attractive biorenewable chemical. Enormous progress has been made in engineering microbes for production of these compounds though titers remain lower than desired. Here we used transcriptome analysis of Escherichia coli during exogenous challenge with octanoic acid (C8) at pH 7.0. This analysis suggests that C8 challenge causes intracellular acidification and membrane damage. Escherichia coli MG1655 was grown to midlog (OD550 ~0.8) with or without 10 mM octanoic acid (pH=7.0) and the RNA was harvested and prepared for Affymetrix Microarray analysis.

Transcription profiling of wine yeast strains during colombar fermentation

Project description:Comparative gene expression analysis of two wine yeast strains at three time points (days 2, 5 and 14) during fermentation of colombar must. In our study we conducted parallel fermentations with the VIN13 and BM45 wine yeast strains in two different media, namely MS300 (syntheticmust) and Colombar must. The intersection of transcriptome datasets from both MS300 (simulated wine must;GSE11651) and Colombar fermentations should help to delineate relevant and ânoisyâ changes in gene expression in response to experimental factors such as fermentation stage and strain identity. Experiment Overall Design: Two industrial wine yeast strains (BM45 and VIN13) grown micro-aerobically in Colombar must. Microarray analysis was performed at three time points during fermentation (days 2, 5 and 14), representing the exponential, early and late stationary growth phases respectively.

CPI-613, Bendamustine Hydrochloride, and Rituximab in Treating Patients With Relapsed or Refractory B-Cell Non-Hodgkin Lymphoma

Project description:This phase I trial studies the side effects and best dose of CPI-613 (6,8-bis[benzylthio]octanoic acid) when given together with bendamustine hydrochloride and rituximab in treating patients with B-cell non-Hodgkin lymphoma that has come back or has not responded to treatment. Drugs used in chemotherapy, such as 6,8-bis(benzylthio)octanoic acid and bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may find cancer cells and help kill them. Giving 6,8-bis(benzylthio)octanoic acid with bendamustine hydrochloride and rituximab may kill more cancer cells.
