CHAC1 further exacerbates cellular stress by degrading GSH, intensifying oxidative damage and ultimately driving ferroptotic cell death (Figure 5) ( FIGURE 5 While the eIF2K3/PERK-eIF2-ATF4 cascade, another branch of the ISR, can modulate ferroptosis in the context of ER stress, cysteine deprivation selectively activates GCN2 rather than PERK, highlighting distinct regulatory mechanisms ( Cysteine starvation triggers mitochondrial fragmentation, impairs mitochondrial function and leads to the accumulation of ROS ( CHAC1 is upregulated through the ATF4-dependent ISR pathway, where it degrades GSH to liberate cysteine needed for the synthesis of Fe-S cluster proteins (Ward et al., 2024)
That makes it theoretically safer metabolically compared to growth hormone

Mondul AM, Sampson JN, Moore SC, Weinstein SJ, Evans AM, Karoly ED,
Treatment with ANXA1 reduces the parasitism rate of placental explants in the third trimester of pregnancy ( In vitro cultured trophoblast cells provide a cellular model for studying the mechanism by which various substances cross the placental barrier
