In Vivo Model
For in vivo experiments, the eyes in each group (n = 6) were enucleated carefully and processed for indirect immunofluorescence in whole-mount or cross-section as previously described. For cryosections, the eyes (n = 3 retinae from 3 mice) were fixed in 4% PFA at room temperature for 15 min. The frozen samples were then sliced transversely (6 um) at -20. For retinal flat-mounts, the eyes (n = 3 eyes from 3 mice) were fixed in 4% PFA at room temperature for 15 min, and the retinae were dissected out as cups. Both cryosections and retinal cups were blocked with PBS containing 0.5% Triton-X100 and 5% BSA at 4 overnight and included with the anti-CD31 and anti-GPX4 (1:100, ab125066, Abcam) primary antibodies.

Response regulation ZFAS1 may act as a competing endogenous RNA by competitively binding with microRNA-7-5p (miR-7-5p) and modulating the expression of its downstream molecule acyl-CoA synthetase long-chain family member 4 (ACSL4), which is now identified as a classic driver gene of ferroptosis process. In conclusion, our results demonstrate that HG-induced ZFAS1 elevation activates ferroptosis in hRECs and the ZFAS1/ miR-7-5p/ACSL4 axis may serve as a therapeutic target for endothelial dysfunction in diabetic retinopathy.
