Project description:The yeast Pichia caribbica shown the capability to degrade patulin by the intracellular enzymes. However, the enzymes which risponsible for the degradation process was unkonown. Transcriptome change in response to mycotoxin patulin was analyzed. The molecular mechanism of Pichia caribbica withstand patulin was revealed.
Project description:The yeast Rhodotorula mucilaginosa shown the capability to degrade patulin by the intracellular enzymes. However, the enzymes which risponsible for the degradation process was unkonown. Transcriptome change in response to mycotoxin patulin was analyzed. The molecular mechanism of Rhodotorula mucilaginosa withstand patulin was revealed.
Project description:Patulin, 4-hydroxy-4H-furo[3,2c]pyran-2(6H)-one, is one of the most popular and characterized mycotoxin observed in agricultural products. However the mechnisims of toxicity by this chemical is not well understood. Thus, we characterized the cytotoxicity of patulin using yeast transcriptome systems. The expression profile of mRNA after exposure yeast cells to patulin was similar to those after the treatment by antifungal agricultural chemicals such as thiuram, maneb, and zeneb. The Patulin treatment activated protein degradation especially proteasome activities, sulfur amino acid metabolisms, and oxidative stress defense system. DNA alkylation damages was also suggested and this seems to be repaired by recombinational and excision repair mechanism. We also list the indicator genes for the detection of patulin in agricultura product. Keywords: stress response
Project description:The assessment of toxicity about patulin using yeast gene expression comparison analysis. Yeast BY4743 derivative SOD1 mutant was used for this study. Ascorbic acid was used to evaluate the anti-toxic effect to patulin. Keywords: stress response Four series of samples were compared with each by ANOVA analysis. Each strain was grown in YPD medium, and they were also incubated with 25 ppm of patulin and 10 mM ascorbic acid.
Project description:To gather more in-depth knowledge of the Mtl1p mechanosensor's role in Saccharomyces cerevisiae metabolism, we conducted a comparative metabolomic analysis of two Saccharomyces cerevisiae strains: the wild type and mtl1Δ, which carries a deletion of the mechanosensor Mtl1p. Both strains were grown under normal conditions at 27°C. The most significant metabolic changes between these strains were related to amino acid metabolism, purine metabolism, and carboxylic acid metabolism.

Project description:A six array study using total gDNA recovered from two separate cultures of each of three different strains of Saccharomyces cerevisiae (YB-210 or CRB, Y389 or MUSH, and Y2209 or LEP) and two separate cultures of Saccharomyces cerevisiae DBY8268. Each array measures the hybridization of probes tiled across the Saccharomyces cerevisiae genome.
Project description:Organoid cultures were exposed to two different E.Coli strains and a dye control with three biological duplicates. Their original culture was harvested as a control. In total 10 organoid cultures were whole-genome sequenced using the Novaseq6000 platforms. The data is deposited as .bam format.
