The effect of aging on the repeated-dose liver micronucleus assay

Miyuki Shigano, Hironao Takasawa & Shuichi Hamada 

In this study, authors conducted the 4-week RDLMN assay using rats of 6 and 8 weeks of age (at the start of administration) to investigate the effect of age on the liver MN inducibility. Clofibrate, a weak inducer of liver MN, was used in this study to detect the slight difference in the liver MN induction.

Masami Yamada studied bacterial genetics and got a PhD degree from Osaka University. Since 1990, using genetic engineering techniques, she has constructed many strains from standard tester strains for the Ames test at the National Institute of Health Sciences, Tokyo. Such strains are useful for research fields on environmental mutagens.
Strain requests come to her every year from domestic, Asia, Europe, North America, South America, and other countries. Currently, she teaches Biology and Genetic Engineering at National Defense Academy of Japan.

About JEMS
The mission of the Japanese Environmental Mutagen and Genome Society (JEMS) is to discover how environmental mutagens affect all organisms, and to promote and apply this knowledge to protect human health and our environment. JEMS was founded in 1972, and since then the society has hosted annual conferences and open symposia on timely topics. The society is a member of the Asian Association of the Environmental Mutagen Societies and the International Association of Environmental Mutagenesis and Genomics Societies.
