Ontology analysis (applied to genes differentially expressed and displaying a FC equal or superior to 2) confirmed this trend with the overrepresentation of ontologies related to stem cells within the genes upregulated in SFTs (“LXR/RXR activation”, “TR/RXR activation”, “LPS/IL-1 mediated inhibition of RXR function”, “PXR/RXR activation”, “ascorbate and aldarate metabolism”, “role of NANOG in mammalian embryonic stem cell pluripotency”, “NFkB signaling”, “WNT/beta-catenin signaling”, “HER2 signaling in breast cancer”, “growth hormone signaling”, “EGF signaling”). The gene discussed is NR1I2; the disease is breast carcinoma.
