Dysfunction of the CFTR (cystic fibrosis transmembrane conductance regulator) protein is associated with an increased risk of GI tumors, both in patients with cystic fibrosis and in sporadic GI cancers (353)

Several RCT investigated the role of liraglutide, alone or in combination with metformin, in women with PCOS and overweight or obesity, confirming its beneficial effect on anthropometric and metabolic features 95

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)
