GSTs conjugate 4HNE to GSH, and the corresponding glutathionyl-4-HNE (GS-HNE) is actively transported out of cells via RLIP76, a multifunctional membrane transporter for GSH-conjugated compounds, and/or MRPs (multidrug-resistance proteins

19 Recent spatial multi-omics studies further support the existence of spatially coordinated ferroptosis-associated programs in injured tubules, with GPX4, ferritin heavy chain 1 (FTH1), and ferritin light chain (FTL) emerging as key spatially enriched markers in regions linked to ferroptotic spread, 93 reinforcing the concept of ferroptosis as a spatially organized tissue response rather than an isolated cellular event
