Fig. 3. The most highly affected pathways and functions in mutant cumulus
cells. The 744 transcripts that were commonly changed in all three
pairwise comparisons of cumulus transcriptomes in WT,
Bmp15-/-, and DM mice were uploaded into the IPA platform,
and canonical pathways and molecular functions analyses were carried out using
Ingenuity Pathways Knowledge Base as reference dataset. (A) All
canonical pathways identified that were significantly affected. (B) The
10 most affected molecular functions. The orange vertical line crossing all
the bars in A and B indicates the threshold of significance (P=0.05),
and bars above this line have a P-value of less than 0.05. (C)
GenMAPP display of transcripts encoding enzymes required for cholesterol
biosynthesis pathway. The list of all the genes on the array was uploaded into
GenMAPP, and significantly downregulated transcripts were defined by the
criteria of FC (fold change) <-1 and Fs P<0.01 in all three
pairwise comparison analyses, and are shown in orange boxes. Upregulated
transcripts are defined by the criteria of FC>1 and Fs P<0.01
in all three pairwise comparison analyses. No transcripts are identified to be
upregulated by these criteria. Dotted boxes indicate that the transcripts in
these boxes are represented by >1 probe set. The FC of each transcript is
listed on the right side of the corresponding box. Only the FCDM vs
WT of each transcript is shown here owing to space limitation. Minor
modification of the original MAPP in GenMAPP was made here in order to cover
most of the key enzymatic steps in this pathway, such as steps for producing
FF-MAS and T-MAS. Panel C, by Michael Lieberman and Ned Mantei (2004), is
reproduced from GenMAPP.
