Project description:Saccharomyces cerevisiae strain BY4741 (MATa his3Δ1 leu2Δ0 met15Δ0 ura3Δ0) was grown in YPD medium. For control conditions, cells were grown in mid-log phase at 30°C for 20 min or 2 hours. Stress conditions were heat shock (37°C for 20 min), diauxic shift (harvested at 2 hours after glucose depletion), DNA damage (harvested after 2 hours of treatment with 5 µg/ml 4-nitroquinoline 1-oxide (Sigma)). Moreover, four conditions of the yeast metabolic cycle were analyzed. S. cerevisiae strain CEN.PK (MATa URA3 TRP1 LEU2 HIS3 MAL2-8C SUC2) was used and cultivated as described elsewhere (Nocetti and Whitehouse, Genes Dev, 2016). The period of metabolic oscillation was approximately 3.2 h. Cells were harvested at 16, 32, 48, and 60 min from the start of each cycle for one oxidative, two reductive/building, and one reductive/charging phase points. Total RNA from each sample was extracted by the hot phenol method and used for library preparation. 3′-seq libraries were prepared as described previously (Lianoglou et al., Genes Dev, 2013). Each condition was sequenced in three biological replicates. The 27 individual libraries were pooled and subjected to sequencing with HiSeq with SR50 at the Integrated Genomics Operation (MSKCC).

Project description:Here we used mass spectrometry-based proteomics technology to explore SEPs with potential cellular stress function in Saccharomyces cerevisiae. Microproteins with unique peptides were identified under six culture conditions: normal, oxidation, starvation, UV radiation, heat shock, and heat shock with starvation.

Project description:Background: Recent studies have demonstrated that antisense transcription is pervasive in budding yeasts and is conserved between Saccharomyces cerevisiae and S. paradoxus. While studies have examined antisense transcripts of S. cerevisiae for inverse transcription in stationary phase and stress conditions, there is a lack of comprehensive analysis of the conditional specific evolutionary characteristics of antisense transcription between yeasts. Here we attempt to decipher the evolutionary relationship of antisense transcription of S. cerevisiae and S. paradoxus cultured in mid log, early stationary phase, and heat shock conditions. Results: Massively parallel sequencing of sequence strand-specific cDNA library was performed from RNA isolated from S. cerevisiae and S. paradoxus cells at mid log, stationary phase and heat shock conditions. We performed this analysis using a stringent set of sense ORF transcripts and non-coding antisense transcripts that were expressed in all the three conditions, as well as in both species. We found the divergence of the condition specific anti-sense transcription levels is higher than that in condition specific sense transcription levels, suggesting that antisense transcription played a potential role in adapting to different conditions. Furthermore, 43% of sense-antisense pairs demonstrated inverse transcription in either stationary phase or heat shock conditions relative to the mid log conditions. In addition, a large part of sense-antisense pairs (67%), which demonstrated inverse transcription, were highly conserved between the two species. Our results were also concordant with known functional analyses from previous studies and with the evidence from mechanistic experiments of role of individual genes. Conclusions: This study provides a comprehensive picture of the role of antisense transcription mediating sense transcription in different conditions across yeast species. We can conclude from our findings that antisense regulation could act like an on-off switch on sense regulation in different conditions.
