FASN and neoplasm: In addition to these canonical targets, we revealed a pronounced increase in lipogenesis in tumors and even PREs, which was evident on several experimental layers: an increase in the level of the master regulators of lipogenesis SCD1 and FASN, an upregulation of lipid metabolism by gene expression analysis, and a lipid‐rich phenotype to an extent, where tumor cells were packed with lipid droplets as seen by electron microscopy.
