High-Throughput In Vivo Genotoxicity Testing: An Automated Readout System for the Somatic Mutation and Recombination Test (SMART)

Genotoxicity testing of Cecropia obtusifolia extracts in two in vivo assays: the wing somatic mutation and recombination test of Drosophila and the human cytokinesis-block micronucleus test.

Cecropia obtusifolia Bertol. (Cecropiaceae) is a tree that grows in secondary vegetation in the tropical rain forest along both coasts of Mexico. Its leaves are used in folk medicine for the treatment of diabetes mellitus type 2. The aim of the present studies was the evaluation of possible genotoxic effects of the aqueous extract from the leaves of Cecropia obtusifolia by means of two differen...

Protection by Panax ginseng C.A. Meyer against the genotoxicity of doxorubicin in somatic cells of Drosophila melanogaster

Panax ginseng is one of the most widely prescribed herbal medicines for the treatment of cancer, diabetes, chronic inflammation, and neurodegenerative and cardiovascular diseases. Since the use of alternative medicines in combination with conventional therapy may increase the risk of unwanted interactions, we investigated the possible genotoxicity of a water-soluble form of the dry root of P. g...

Genotoxicity testing of some metals in the Drosophila wing somatic mutation and recombination test.

Antigenotoxic effects of Mandevilla velutina (Gentianales, Apocynaceae) crude extract on cyclophosphamide-induced micronuclei in Swiss mice and urethane-induced somatic mutation and recombination in Drosophila melanogaster

A Mandevilla velutina crude extract was investigated using the mouse micronucleus test (MNT) and the Drosophila melanogaster somatic mutation and recombination test (SMART) using standard (ST) and high bioactivation (HB) crosses. The MNT used 10 mg, 20 mg or 40 mg per 100 g of body weight (bw) of extract with and without 0.2 mg per 100 g bw peritoneal cyclophosphamide. There was no genotoxicity...

Recombinagenic activity of four compounds in the standard and high bioactivation crosses of Drosophila melanogaster in the wing spot test.

The wing somatic mutation and recombination test (SMART) using Drosophila melanogaster was employed to determine the recombinagenic and mutagenic activity of four chemicals in an in vivo eukaryotic system. Two different crosses involving the wing cell markers mwh and flr(3) were used: the standard cross and a high bioactivation cross. The high bioactivation cross is characterized by a high cons...
