In Vivo Model
All athymic nude mice (6-week-old) were purchased from Jiesijie (Shanghai, China). To generate routine cell-derived xenograft (CDX) mouse models, established LUAD cells (initial 5 x 106) were subcutaneously injected into the bilateral dorsal flank of athymic nude mice. To generate H1975/A549 cell-implanted intrapulmonary LUAD mice, athymic nude mice were intrapulmonarily injected with cells (5 x 106) under anesthesia and then intranasally administered adeno-associated virus 5 (AAV5) particles (2 x 1012 viral particles/mL, Genomeditech, Shanghai, China) 3 weeks later. To generate patient-derived xenograft (PDX) mouse models, fresh LUAD tissues with a size of 2-3 mm3 were subcutaneously implanted into athymic nude mice. After successful passage, the PDX mice were used for further studies.

Response regulation Intracellular cir93-FABP3 interactions are critical to upregulate FABP3 to reduce global AA via reactions with taurine. The product of AA and taurine (i.e., NAT) prevents AA incorporation into the plasma membrane, thus further reducing the opportunity for PUFA peroxidation in the membrane. NAT reduces ACSL4, LPCAT3 and PLTP. Exosome and cir93 are critical to desensitize lung adenocarcinoma to ferroptosis.
