To evaluate which extracellular molecules among those predicted to be activated from the IPA results are potentially able to trigger signaling pathways for elevating FBXL7 expression, we performed a Pearson’s correlation test to estimate the relationships among FBXL7, CD44, HGF, CSF2, PDGFA, PDGFB, PDGFC, and PDGFD transcripts in patients with ovarian serous cystadenocarcinoma using the TCGA database. This evidence concerns the gene CSF2 and ovarian serous cystadenocarcinoma.
