Reproductive Toxicity and Multi/Transgenerational Effects of Emerging Pollutants on C. elegans

Area of Science:

• Environmental toxicology
• Reproductive toxicology
• Molecular toxicology

Background:

• Emerging pollutants (EPs) pose significant threats to environmental and human health.
• Risk assessment for EPs necessitates the use of model organisms.
• Caenorhabditis elegans (C. elegans) is a well-established model organism for toxicological studies due to its rapid development and short generation cycle, making it ideal for transgenerational research.

Purpose of the Study:

• To review the reproductive toxicities of emerging pollutants (EPs) in C. elegans.
• To investigate the transgenerational effects of EPs on nematode reproduction.
• To discuss the underlying molecular mechanisms of EP-induced reproductive toxicity.

Main Methods:

• Literature review of studies on emerging pollutants and C. elegans.
• Analysis of research focusing on reproductive endpoints in nematodes exposed to EPs.
• Examination of studies investigating germ cell apoptosis, spermatogenesis, and epigenetic alterations in response to EPs.

Main Results:

• EPs can cause reproductive toxicity in contemporary C. elegans.
• Transgenerational effects of EPs on reproductive health were observed.
• Mechanisms include germ cell apoptosis, impaired spermatogenesis, and epigenetic modifications.

Conclusions:

• C. elegans is a valuable model for studying the reproductive and transgenerational impacts of EPs.
• EPs pose a significant risk to reproductive health across generations.
• Further research is needed to fully elucidate the mechanisms and long-term consequences of EP exposure.
