The List Manager can be used to generate lists of genes by applying criteria such as fold change and false discovery rate (FDR) adjusted p-value thresholds. 

  • Select the Analysis tab
  • Select ANOVAResults in the spreadsheet tree
  • Select Create Gene List from the Analysis section of the Gene Expression workflow (Figure 1)

  • Select E2 vs. Control from the Contrast panel of the ANOVA Streamlined tab in the List Manager dialog
  • Deselect the Include size of the change option
  • Set p-value with FDR < to 0.1 (Figure 2)

There should be ~545 probe(sets)/genes that meet this threshold.

 

  •  Select Create 

A new spreadsheet, E2 vs. Control will be added as a child spreadsheet of Breast_Cancer.txt

  • Repeat the steps listed above to create lists for E2+ICI vs. Control (~24 genes),E2+Ral vs. Control (~22 genes), and E2+TOT vs. Control (~177 genes) with the same threashold

Now we can use the Venn Diagram to create a list of genes that are differentially regulated in all treatment groups.

  • Select the Venn Diagram

The Venn Diagram shows the amount of overlap between all selected gene lists. 

  • Select the four created lists (E-H) in the spreadsheet list 

The Venn Diagram will display the number of overlapping and distinct genes from four lists (Figure 3).

The intersection of the four ellipses shows that 14 genes are in common between the four threatment schemes. 

  • Select the region intersecting all four ellipses
  • Right-click
  • Select Create List From Highlighted Regions
  • Select Close to exit the List Manager dialog

The new list will appear in the spreadsheet tree with a temporary file name (ptpm). 

  • Select the temporary list in the spreadsheet tree
  • Select () from the command bar
  • Save the list as fourtreatments
