Mouse models for radiation-induced cancers

Area of Science:

• Oncology
• Radiation Biology
• Genetics

Background:

• Ionizing radiation exposure, accidental or therapeutic, elevates cancer risk.
• Long-term effects of radiation exposure include mutations and precancerous cell replication.
• Developing mitigation treatments requires understanding radiation-induced carcinogenesis.

Purpose of the Study:

• To review inbred mouse models (Mus musculus) for studying radiation-induced cancers.
• To describe methods of cancer induction and molecular pathologies in these models.
• To identify suitable animal models for preclinical research on radiation exposure consequences.

Main Methods:

• Review of relevant inbred and F1 hybrid Mus musculus strains.
• Description of cancer induction methods (e.g., single whole-body dose, fractionated doses).
• Analysis of associated molecular pathologies for radiation-induced myeloid leukemia, thymic lymphoma, breast, and lung cancers.

Main Results:

• Mus musculus strains are valuable for radiation cancer research due to physiological similarities with humans.
• Specific mouse models are suitable for investigating radiation-induced myeloid leukemia, thymic lymphoma, breast, and lung cancers.
• Detailed methods and molecular pathways for cancer induction are presented for each model.

Conclusions:

• Well-understood mouse models are essential for accurately recapitulating radiation-induced carcinogenesis.
• This review provides a resource for selecting appropriate Mus musculus models for radiation oncology research.
• Understanding these models can facilitate the development of novel therapeutic agents to mitigate radiation-induced cancer risk.
