Abstract

Sodium azide (NaN3) is a chemical of rapidly growing commercial importance. It is very acutely toxic and inhibits cytochrome oxidase (COX) by binding irreversibly to the heme cofactor. A previous study from our group demonstrated that hydrogen sulfide (H2S), the third endogenous gaseous mediator identified, had protective effects against neuronal damage induced by traumatic brain injury (TBI). It is well‑known that TBI can reduce the activity of COX and have detrimental effects on the central nervous system metabolism. Therefore, in the present study, it was hypothesized that H2S may provide neuroprotection against NaN3 toxicity. The current results revealed that NaN3 treatment induced non‑apoptotic cell death, namely autophagic cell death, in PC12 cells. Expression of the endogenous H2S‑producing enzymes, cystathionine‑β‑synthase and 3‑mercaptopyruvate sulfurtransferase, decreased in a dose‑dependent manner following NaN3 treatment. Pretreatment with H2S markedly attenuated the NaN3‑induced cell viability loss and autophagic cell death in a dose‑dependent manner. The present study suggests that H2S‑based strategies may have future potential in the prevention and/or therapy of neuronal damage following NaN3 exposure.
