Hycanthone as a specific frameshift mutagen in Saccharomyces cerevisiae. 1980

G Lucchini, and S Sora, and L Panzeri

Reversion of mutations of different molecular nature was studied after treatment with hycanthone in mild conditions (0.05--0.4 mM, 4 h in the dark, pH 7.2). The mutagen had a very low reversion activity on 3 missense and 4 nonsense mutations (2 UAA and 2 UAG), although it was very active on 3 frameshift mutations. Our data on intragenic reversion and frameshift suppressors indicate that hycanthone can induce both insertions and deletions.

D006826	Hycanthone	Potentially toxic, but effective antischistosomal agent, it is a metabolite of LUCANTHONE.
D012441	Saccharomyces cerevisiae	A species of the genus SACCHAROMYCES, family Saccharomycetaceae, order Saccharomycetales, known as "baker's" or "brewer's" yeast.

D013489	Suppression, Genetic	Mutation process that restores the wild-type PHENOTYPE in an organism possessing a mutationally altered GENOTYPE. The second "suppressor" mutation may be on a different gene, on the same gene but located at a distance from the site of the primary mutation, or in extrachromosomal genes (EXTRACHROMOSOMAL INHERITANCE).
