Abstract

Exposure of yeast cells to allyl alcohol results in intracellular production of acrolein. The toxicity of so formed acrolein involves oxidative stress, as (1) strains deficient in antioxidant defense are hypersensitive to allyl alcohol, (2) exposure to allyl alcohol increases the level of thiobarbituric-acid-reactive substances and decreases glutathione level in the cells, (3) hypoxic and anoxic atmosphere and antioxidants protect against allyl alcohol toxicity, and (4) allyl alcohol causes activation of Yap1p. No increased formation of reactive oxygen species was detected in cells exposed to allyl alcohol, so oxidative stress is due to depletion of cellular thiols and thus alteration in the redox state of yeast cells.
