Meanwhile, in the aging kidney, REST expression was enhanced in podocytes, while conditional knockout of REST in podocytes induced cell apoptosis (34)

In summary, this dual role highlights that physiological H 2 S promotes Treg differentiation via epigenetic (Tet1/Tet2) and metabolic (LKB1-AMPK) pathways to maintain immune homeostasis, whereas excessive tumor-derived H 2 S over-activates Tregs through ENO1 persulfidation, driving pathological immunosuppression ( Figure 6B )

The explanation for this discrepancy can be found in recent papers showing that some cancer cell linesincluding HCT116are not affected by L-BSO or GSH synthesis inactivation because they can compensate GSH depletion by the thioredoxin (TXN) pathway 25 , and by maintaining protein homeostasis through deubiquitinating enzymes (DUB) 32
