NFE2L2 and non-small cell lung carcinoma: Ginkgetin, a natural biflavonoid isolated from the leaves of Ginkgo biloba L., has been found to induce ferroptosis in non-small cell lung cancer cells through decreased expression of xCT and GPX4, decreased GSH/glutathione disulfide (GSSG) ratio, and inactivation of the Nrf2/HMOX1 axis.
