Also, some pathways were significantly enriched in epithelial cells or malignant tumor cells including fatty acid metabolism, estrogen response late, estrogen response early, apical junction, androgen response, adipogenesis, xenobiotic metabolism, protein secretion, interferon-alpha response, interferon-gamma response, oxidative phosphorylation, and peroxisome (Figure 7D). The gene discussed is IFNG; the disease is cancer.
