H2S Persulfidation Links Homocysteine to Ferroptosis
2026-09-17
Zheng et al. identify hydrogen sulfide-mediated persulfidation of S-adenosyl homocysteine hydrolase as a metabolic mechanism that sensitizes non-small cell lung cancer cells to ferroptosis. The study connects reduced homocysteine metabolism with depletion of cysteine and glutathione, providing a mechanistic rationale for combining hydrogen sulfide signaling with cystine-depletion strategies.
