Cholesterol is indispensable for the proliferation of cancer cells, providing several essential biological functions: (1) maintenance of cell membrane structure [9]; (2) providing a platform for growth signalling proteins, such as the vascular endothelial growth factor receptor-1 (VEGFR-1) [10]; and (3) modulation of the cell cycle by intermediate cholesterol metabolites [11]. Here, FLT1 is linked to cancer.
