Methods & Results

Sample to data relationship table:

• GSE6068_setA_family - swt vs nswt 1mM @ 1 hr (6 replicates); 15 min, 30 min, 18 hrs (3 replicates each)
• GSE6129_set0_family - swt vs nswt 1mM @ 1hr; 6 replicates
• GSE6129_set1_family - swt vs nswt .2mM @ 1 hr, 15 min, 30 min, 18 hr; 3 replicates each
• GSE6129_set2_family - sYAP4 vs swt .2mM AND 1 mM each @ 1 hr, 3 replicates each
• GSE6129_set3_family - sMET4 vs swt .2mM AND 1 mM each @ 1 hr, 3 replicates each

Organizing the Data

1. Downloaded data from Thorsen et al.
2. Changed "Name" to "Standard_ID" in column C.
   • Names were changed to the standard names by the "ORF List <-> Gene List" tool from YEASTRACT.
3. Changed column headers in each sheet:
   • swt = stressed wild type, nswt= nonstressed wild type
   • 1mM, 0.2mM = concentration of As(III) at which the cell was exposed
   • 1h, 15m, 30m, 18h = time point (h = hours, m = minutes)
   • rn = replicate number (n)
4. Inserted MasterIndex in "GSE6068_setA_family"sheet.

Conducting the ANOVA

• All data analysis was conducted on data on the "GSE6068_setA_family" sheet.
• ANOVA procedure was based on the methods from Week 8.

1. A new sheet called "swtVnwt_1mM_ANOVA" was created and all data from Columns A-R was copied and pasted into this sheet.
2. Columns S-V were called "swtVnwt_AvgLogFC_1mM_15m" changing the last part for each time point 15m, 30m, 60m, and 1080m respectively and contained the equation the average of each replicate for each time point.
3. Column "swtVnwt_ss_HO" was created containing the equation SUMSQ(all LogFC values in row).
4. Columns X-AA were named "swtVnwt_ss_15m" changing the last part for each time point 15m, 30m, 60m, and 1080m respectively and contained the equation =SUMSQ(average LogFC at that time point)-COUNTA(average LogFC at that time point)*V2^2.
5. Named column AB "swtVnwt_SS_full" and inserted the sum of columns X-AA.
6. The next column was named "swtVnwt_Fstat" and inserted the equation =((15-4)/4)*(<swtVnwt_ss_HO>-AB2)/AB2.
7. Column "swtVnwt_p-value" was created and the =FDIST(<swtVnwt_Fstat>,4,15-4) equation was inputed.
8. A sanity check was run:
   • 1068/4785 p-values are less than 0.05
9. Two "swtVnwt_Bonferroni_p-value" columns were created, one containing the equation <swtVnwt_p-value>*4785 and the other containing the equation =IF(AE2>1,1,AE2).
10. A new sheet called "swtVnwt_1mM_ANOVA_B-H" was created, and we copied and pasted Columns A-C in it and pasted column "swtVnwt_p-value" in column D.
11. Genes were ranked by p-value and then by MasterIndex.
12. Column "swtVnwt_B-H_p-value" was created containing the equation =(D2*4785)/E2 and then replicated into column G. This column was then pasted into the previous sheet.

Conclusion

We were able to reorganize the data in the way that was best suited for further ANOVA, statistical, and database analyses. We determined that a certain number of genes have p-values less than 0.05, and BH values were determined as well. So far, ANOVA analysis has been completed on the SetA family dataset.
