Consistently, culturing ovarian cancer cells with ascites or omental conditioned medium (OCM) with plenty of free fatty acids by nature demonstrated a remarkable upsurge in cell growth, migration and invasion of metastatic ovarian cancer through upregulation of various signaling cascades like AKT/ERK/FOXM1 and TAK1/FASN/CPT1A/NF-κB axes [36,52,65,66]. This evidence concerns the gene FASN and ovarian cancer.
