Questions about your article
- What is the main result presented in this paper?
- CHP exposure changes the transcriptional response of yeast via its oxidative stress response. The researchers observed the changes in yeast transcription from minutes 0-20, noting many significant changes in minutes 0-6.
- Implicated pathways include oxidative phosphorylation, galactose metabolism, ATP synthesis, proteasome proteolysis, and glutathione & thioredoxin systems.
- CHP exposure changes the transcriptional response of yeast via its oxidative stress response. The researchers observed the changes in yeast transcription from minutes 0-20, noting many significant changes in minutes 0-6.
- What is the importance or significance of this work?
- This paper was the first to note the early (0-6 minutes post-exposure) transcriptional response by yeast to CHP.
- The researchers found that Yap3, 5, and 7 are involved in the yeast OSR, and that their functions were not previously known.
- What were the limitations in previous studies that led them to perform this work?
- Some similar studies did not have biological replicates, nor control groups.
- This study is unique as there was no incubation with CHP before monitoring the transcriptional change. Some other studies waited 10+ minutes to begin analyzing the changes in transcription.
- How did they treat the yeast cells (what experiment were they doing?)
- What strain(s) of yeast did they use? Were the strain(s) haploid or diploid?
- What media did they grow them in? What temperature? What type of incubator? For how long?
- What controls did they use?
- How many replicates did they perform per treatment or timepoint?
- What method did they use to prepare the RNA, label it and hybridize it to the microarray?
- What mathematical/statistical method did they use to analyze the data?
- Are the data publicly available for download? From which web site?
- Briefly state the result shown in each of the figures and tables, not just the ones you are presenting.
- What do the X and Y axes represent (if applicable)?
- How were the measurements made?
- What trends are shown by the plots and what conclusions can you draw from the data?
- How does this work compare with previous studies?
- What are the important implications of this work?
- What future directions should the authors take?
- Give a critical evaluation of how well you think the authors supported their conclusions with the data they showed. Are there any major flaws to the paper?
