Hydrogen sulfide (H2S) is now admitted as a third gasotransmitter together with nitric oxide (NO) and carbon monoxide (CO), albeit it was originally considered as a foul and poisonous gas. Endogenous H2S production in mammalian cells is counting on the

Antioxidants & redox signaling, 27(10), 684-712 (2017-04-12)
Oxidative stress is thought to account for aberrant redox homeostasis and contribute to aging and disease. However, more often than not, administration of antioxidants is ineffective, suggesting that our current understanding of the underlying regulatory processes is incomplete. Recent Advances:

The induction of excessive autophagy by increased levels of oxidative stress is one of the main mechanisms underlying unilateral ureteral obstruction (UUO)-induced vascular endothelial cell dysfunction. Hydrogen sulfide (H2S) has been shown to have an anti-oxidative effect, but its mode
