A lifetime passion for micronucleus cytome assays--reflections from Down Under

Area of Science:

• Genetic Toxicology
• Molecular Biology
• Biomedical Science

Background:

• The development of the cytokinesis-block micronucleus (CBMN) assay is traced from its origins.
• The assay evolved into a comprehensive cytome assay, assessing chromosome breakage, loss, and rearrangements.
• Key cellular events like cell death and cytostasis are also evaluated.

Discussion:

• The laboratory's role in establishing the Human Micronucleus (HUMN) project and its outcomes are discussed.
• Applications of CBMN cytome assays span radiation biology, genetic toxicology, epidemiology, and biodosimetry.
• The concept of Genome Health Clinics emerged from these advancements.

Key Insights:

• The CBMN assay provides a multi-endpoint evaluation of genome instability.
• The HUMN project standardized and promoted the use of CBMN assays globally.
• Applications demonstrate the assay's utility in diverse fields from radiation to nutrigenomics.

Outlook:

• Future applications may focus on health optimization and disease prevention through mutagenesis principles.
• The integration of genome health principles into mainstream medicine is envisioned.
• Inspiring the next generation of scientists to advance mutagenesis research for health benefits.
