In lung adenocarcinoma, exosomal circRNA_101093 interacts with and increases fatty acid binding protein 3 (FABP3), a polyunsaturated fatty acid essential for the increased plasma membrane peroxidation associated with iron death, FABP3 transports AA and promotes its reaction with taurine, and AA decreases, preventing AA adulteration of the plasma membrane desensitizing LUAD cells to iron death (134). This evidence concerns the gene FABP3 and lung adenocarcinoma.
