A previous study from Wang GY showed that NaB promoted ferroptosis by inducing lipid ROS production via downregulating the expression of solute carrier family 7, membrane 11 (SLC7A11), and GPX4 through regulating the free fatty acid receptor 2 (FFAR2)-mammalian target of rapamycin (mTOR) signaling in colorectal cancer in HT29 cells [44]. Here, FFAR2 is linked to colorectal cancer.
