Purpose
- To analyze data collected by Thorsen et al. regarding gene expression changes in response to sulfate exposure through using an ANOVA, running STEM, YEASTRACT, GRNsight, GRNmap, and Microsoft Access
- To check the efficacy of the work done by Thorsen et al.
Methods and Results
Loading Data into STEM
- Downloaded all STEM software needed found on Week 9.
- Deleted the "1080" data column from the "swtVnwt_1mM_stem" sheet found in the Thorsen Data Excel File.
- This was done so that the profile graphs were clearer
- Converted this file into a .txt file
- Ran STEM with this file under these parameters:
- No normalization/add 0
- Spot IDs included in the data file
- Browse: gene_association.sgd.gz
- Selected "X-axis scale should be: Based on real time" in the Interface Options on the All STEM Profiles (1) pop-up window.
- All genelists and GOlists for the significant profiles (9,23,40, and 48) were downloaded and saved.
- Profiles 9 and 23 were colored red to show clusters that were involved in down-regulation.
- Profiles 40 and 48 were colored green to show clusters that were involved in up-regulation.
- Copied the gene lists from Profile 9 and 23 and inputted them into
Data and Files
Conclusion
The data analysis performed produced various graphs showing expression trends and networks that depicted regulation between genes.
