Animal models of epigenetic inheritance

Area of Science:

• Genetics
• Developmental Biology
• Epigenetics

Background:

• Genomic DNA dictates heredity, but gene expression regulation creates organismal diversity.
• Epigenetics, heritable gene expression changes without DNA sequence alteration, modulates gene activity.
• Epigenetic mechanisms are vital for adaptation to environmental factors and early development.

Purpose of the Study:

• To review animal models developed for studying epigenetic inheritance.
• To highlight the connection between epigenetics, developmental origins of health and disease (DOHaD), and adult health.

Main Methods:

• Focus on animal models developed over the last decade.
• Review literature connecting epigenetic inheritance studies with DOHaD research.

Main Results:

• Animal models provide powerful tools for investigating epigenetic inheritance mechanisms.
• These models facilitate understanding how environmental factors influence heritable epigenetic changes.
• Research highlights the role of epigenetics in developmental plasticity and long-term health outcomes.

Conclusions:

• Epigenetic inheritance is a key area for understanding biological complexity and adaptation.
• Animal models are essential for dissecting the role of epigenetics in health and disease across generations.
• Further research using these models will advance our knowledge of developmental origins of health and disease.
