Caenorhabditis elegans as an emerging model system in environmental epigenetics

Area of Science:

• Environmental Epigenetics
• Toxicology
• Developmental Biology

Background:

• Caenorhabditis elegans (C. elegans) has been a model organism since the 1970s for genetics and developmental biology.
• Its utility has expanded to environmental toxicology, particularly chemical genotoxicity.
• C. elegans is increasingly used to study epigenetics and chromatin biology.

Purpose of the Study:

• To outline the utility and applicability of C. elegans for studying environmental influences on the epigenome.
• To inform the field of environmental epigenetics about the strengths and limitations of C. elegans.
• To highlight C. elegans as a model for exploring exogenous chemical stimuli in transcriptional regulation, epigenetic reprogramming, and inheritance.

Main Methods:

• Utilizing C. elegans as a model organism for in vivo studies.
• Investigating the role of environmental factors on epigenetic mechanisms.
• Medium-throughput exploration of chemical stimuli effects on gene regulation.

Main Results:

• C. elegans serves as a powerful model for mechanistic studies of environmental epigenetics.
• It is applicable for exploring the impact of chemical stimuli on transcriptional regulation.
• The model facilitates research into developmental epigenetic reprogramming and epigenetic memory.

Conclusions:

• C. elegans is a valuable, scalable in vivo system for environmental epigenetics research.
• It bridges in vitro and mammalian model systems for studying human transcriptional regulatory circuits.
• The model aids in understanding exogenous chemical influences on the epigenome.
