Transcription profiling of yeast grown in SD media with addition of either methionine or hydrogen peroxide

ABSTRACT: Yeast cells were grown up in SD media containing all required amino acids. Each strain set was performed in triplicate. One set had no changes, the second set had 1mM methionine supplenting the media for the duration of growth and the third set was exposed to 0.5mM hydrogen peroxide for 15 minutes prior to harvesting

Gcn4 is required for the response to peroxide stress in the yeast Saccharomyces cerevisiae.

An oxidative stress occurs when reactive oxygen species overwhelm the cellular antioxidant defenses. We have examined the regulation of protein synthesis in Saccharomyces cerevisiae in response to oxidative stress induced by exposure to hydroperoxides (hydrogen peroxide, and cumene hydroperoxide), a thiol oxidant (diamide), and a heavy metal (cadmium). Examination of translational activity indicates that these oxidants inhibit translation at the initiation and postinitiation phases. Inhibition o ...[more]

Transcription profiling of Saccharomyces cerevisiae reveals the Cbf1 basic helix-loop-helix transcription factor is required for the response to hydrogen peroxide stress

Project description:Cbf1 is a basic helix-loop-helix transcription factor which regulates the expression of many genes of the sulphur assimilation pathway in yeast. Gamma-glutamylcysteine synthetase (GSH1), encoding the rate-limiting enzyme in glutathione biosynthesis, is constitutively elevated in cbf1 mutants indicating that Cbf1 normally represses GSH1 expression. We used transcriptional profiling to show that a number of antioxidant and stress genes are similarly repressed by Cbf1, consistent with the high oxidant tolerance of cbf1 mutants. Our data indicate that Cbf1 plays a key role in the regulation of gene expression during oxidative stress conditions induced by exposure to hydrogen peroxide. The Yap1 transcription factor induces GSH1 expression in response to hydrogen peroxide in a mechanism that does not require the Met4 transcription factor to overcome the inhibitory action of Cbf1. We show that hydrogen peroxide does not affect Cbf1 occupancy on the GSH1 promoter, but results in specific modification of Cbf1 by phosphorylation. Our data indicate that casein kinase (CK2) can directly phosphorylate Cbf1 in vitro. Furthermore, CK2 activity is required to phosphorylate Cbf1 and induce GSH1 expression in yeast cells in response to hydrogen peroxide. CK2 mutants are sensitive to hydrogen peroxide consistent with a role for CK2 in regulating the cellular response to oxidative stress. CK2 is a ubiquitous serine/threonine protein kinase and the finding that it is regulated by oxidative stress is particularly interesting, since there is increasing evidence that it is involved in a number of pathological conditions including cancer, neurodegenerative and cardiovascular diseases.

Transcription profiling of yeast grown in gastric or duodenal medium to identify promoters that could be used to down-regulate genes used in the release of therapeutic proteins

Project description:The use of yeast as a delivery system is an attractive option for the oral administration of therapeutic agents. We recently developed mutants of Saccharomyces cerevisiae capable of lysis upon conditional down-regulation of the expression of the cell wall genes PKC1 and SRB1. The lysis mechanism of the mutant is based on the use of the MET3 promoter, which, upon addition of methionine and cysteine, blocks transcription of SRB1 and PKC1. This strain has the potential to be an integral part of an oral yeast delivery system, in which there is lysis of yeasts in the human gut, followed by release of recombinant proteins for therapeutic use. In order to provide proof-of-principle, the system was evaluated testing the cells viability and lysis performance under conditions, which simulate those found in the human stomach and the duodenum. Upon incubation of yeast cells in these conditions, lysis could be induced and was accompanied by release of GFP reporter protein into the medium. However, the conditional lysis mechanism based on the MET3 promoter is not applicable in vivo. Therefore, alternative promoters suitable for in-vivo down-regulation of SRB1 and PKC1 were identified by a microarray experiments. The transcripts of genes ANB1, TIR1, and MF(ALPHA)2 were significantly reduced upon exposure of the yeast cells to conditions of the two gut compartments. Their promoters could be used to down-regulate SRB1/VIG9 and PKC1 in vivo to achieve lysis of the yeast in the gut to release cargo therapeutic proteins.
