Combining the in vivo comet and micronucleus assays: a practical approach to genotoxicity testing and data interpretation

Despite regulatory directives requiring the reduction of animal use in safety testing, recent modifications to genotoxicity testing guidelines now propose the use of two in vivo genotoxicity assays as a follow-up to an in vitro positive (International Conference on Harmonization Consensus Draft Guidance S2[R1] released March, 2008). To address both goals, the in vivo comet and micronucleus (MN)...

A Novel Strategy to Predict Carcinogenicity of Antiparasitics Based on a Combination of DNA Lesions and Bacterial Mutagenicity Tests

Genotoxicity and carcinogenicity testing of pharmaceuticals prior to commercialization is requested by regulatory agencies. The bacterial mutagenicity test was considered having the highest accuracy of carcinogenic prediction. However, some evidences suggest that it always results in false-positive responses when the bacterial mutagenicity test is used to predict carcinogenicity. Along with maj...

Soybean aphid (Hemiptera: Aphididae) development on soybean with Rag1 alone, Rag2 alone, and both genes combined.

Aphis glycines Matsumura (Hemiptera: Aphididae) can reduce the yield of aphid-susceptible soybean (Glycine max (L.) Merrill) cultivars. The Rag1 and Rag2 genes conferresistance to some biotypes of A. glycines. These genes individually can limit population growth of A. glycines and prevent yield loss. The impact of these genes when combined is not known. We compared the development of A. glycine...
