[Analysis of the mutagenic and teratogenic effect of griseofulvin in the mutagen-sensitive Drosophila melanogaster line mus(2)201G1]. 1994

O A Isaenko, and T B Romashkina, and P Ia Shvartsman, and L F Shelomova

The mutagenic effect of griseofulvin was demonstrated in a wing somatic mosaicism test (SMART) in different Drosophila lines. The mutagenic effect of this agent is accompanied by a pronounced toxic effect on Drosophila larvae and by a teratogenic effect, which is manifested in the reduction of ommatidia, phenocopying the mutation ey (eyeless-4:2.0). A relationship was shown between the level of the phenocopies and the dose of griseofulvin (GF), the genotypes of the treated larvae, the interval and duration of GF exposure, and also sexual differences. The lowest level of phenocopies is recorded for the line developed on the basis of the mutagen-sensitive mutation mus(2)201G1, which blocks excision repair.

UI MeSH Term Description Entries
D008297 Male Males
D009030 Mosaicism The occurrence in an individual of two or more cell populations of different chromosomal constitutions, derived from a single ZYGOTE, as opposed to CHIMERISM in which the different cell populations are derived from more than one zygote.
D009153 Mutagens Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes. Clastogen,Clastogens,Genotoxin,Genotoxins,Mutagen
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D004331 Drosophila melanogaster A species of fruit fly frequently used in genetics because of the large size of its chromosomes. D. melanogaster,Drosophila melanogasters,melanogaster, Drosophila

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
