ABSTRACT
This study evaluated different concentrations of selective serotonin-reuptake inhibitors (citalopram and sertraline) for genotoxicity by use of the somatic mutation and recombination test (SMART) in Drosophila melanogaster. Three-day-old larvae, trans-heterozygous for the multiple wing hairs (mwh) and flare (flr³) genes were treated with these two compounds. Two recessive markers were located on the left arm of chromosome 3, i.e. 'multiple wing hairs' (mwh) in map position 0.3 and 'flare-3' (flr³) at 38.8, while the centromere was located in position 47.7. SMART is based on the loss of heterozygosity, which may occur through various mechanisms, such as mitotic recombination, mutation, deletion, half-translocation, chromosome loss, and non-disjunction. Genetic changes occurring in somatic cells of the wing's imaginal discs, cause the formation of mutant clones on the wing blade. The results of this study show that citalopram had a genotoxic effect in the Drosophila SMART. Sertraline, however, did not show any genotoxic effect in balancer heterozygous wings. This study concluded that more information is needed to be certain regarding the mutagenic effects of sertraline.
