In addition, western blot results indicated that the expression of ferritin heavy-chain (FTN-H) was down-regulated, and cystine-glutamate antiporter (xCT) was up-regulated by Cana in DCM mice and cells, suggesting that Cana inhibit ferroptosis by balancing cardiac iron homeostasis and promoting the system Xc-/GSH/GPX4 axis in DCM. This evidence concerns the gene SLC7A11 and familial dilated cardiomyopathy.
