KP1019 (trans-[tetrachlorobis(1H-indazole) ruthenate(III)]) Dependent Transcription in WT Saccharomyces cerevisiae

ABSTRACT: To characterize cellular response to the anti-cancer ruthinium complex KP1019, budding yeast Saccharomyces cerevisiae transcripitonal response to KP1019 was measured using microarray analysis. Although KP1019 molecular mechanism of action remains a matter of debate, the drug has been shown to bind DNA in biophysical assays and to damage DNA of colorectal and ovarian cancer cells in vitro. KP1019 has also been shown to induce mutations and induce cell cycle arrest in Saccharomyces cerevisiae, suggesting that budding yeast can serve as an appropriate model for characterizing the cellular response to the drug. Here we use a transcriptomic approach to characterize KP1019 induced transcriptional changes.

Here we use a transcriptomic approach to characterize KP1019 induced transcriptional changes. Two concentrations of KP1019 (40 micrograms/mL and 80 micrograms/ml were assayed by microarray analysis to obtain comparative expression data for treated and untreated cells of the budding yeast Saccharomyces cerevisiae (strain BY4741). Two biological replicates of each concentration were done. Each biological replicate was done in duplicate to allow for dye reversal controls.

Small RNAs in budding yeast

Project description:RNAi, a gene-silencing pathway triggered by double-stranded RNA, is conserved in diverse eukaryotic species but has been lost in the model budding yeast, Saccharomyces cerevisiae. We report that RNAi is present in other budding-yeast species, including Saccharomyces castellii and Candida albicans. These species use noncanonical Dicer proteins to generate siRNAs, which mostly correspond to transposable elements and YM-BM-4 subtelomeric repeats. In S. castellii, RNAi mutants are viable but have excess YM-BM-4 mRNA levels. In S. cerevisiae, introducing Dicer and Argonaute of S. castellii restores RNAi, and the reconstituted pathway silences endogenous retrotransposons. These results identify a novel class of Dicer proteins, bring the tool of RNAi to the study of budding yeasts, and bring the tools of budding yeast to the study of RNAi. Employ high-throughput sequencing of endogenous small RNAs from the budding yeasts Saccharomyces castellii, Kluyveromyces polysporus, Candida albicans, Saccharomyces cerevisiae, and Saccharomyces bayanus.

We report that RNAi is present in other budding-yeast species, including Saccharomyces castellii and Candida albicans. These species use noncanonical Dicer proteins to generate siRNAs, which mostly correspond to transposable elements and Y´ subtelomeric repeats.

In S. cerevisiae, introducing Dicer and Argonaute of S. castellii restores RNAi, and the reconstituted pathway silences endogenous retrotransposons. These results identify a novel class of Dicer proteins, bring the tool of RNAi to the study of budding yeasts, and bring the tools of budding yeast to the study of RNAi.
