In this protective role, ATF4 drives the expression of the chaperone heat shock protein family A (Hsp70) member 5 (HSPA5), which in turn stabilizes and enhances the activity of GPX4, thereby inhibiting ferroptotic cell death ( In ferroptosis resistant melanoma cells, CHAC1 was shown to be upregulated by NRF2 independent from ER stress signaling alongside the Aldo-Keto Reductase Family 1 Member C1 (AKR1C1) capable of degrading lipid radicals ( CHAC1 , most melanoma cell lines appear to be resistant against ferroptosis
The administration of ghrelin to rats deprived of food before refeeding prevents the downregulation of MCH and CB-1 receptors in VANs, suggesting that ghrelin mediates the expression of orexigenic receptors to induce food intake (90)
