Endocrine disruption in nematodes: effects and mechanisms

Area of Science:

• Ecotoxicology
• Endocrinology
• Nematology

Background:

• Nematodes play a crucial role in aquatic ecosystems but are understudied in ecotoxicology.
• While lacking a known endocrine system, nematodes exhibit hormonal regulation of key processes.
• Vertebrate hormones may influence nematode functions, suggesting susceptibility to endocrine disrupting chemicals (EDCs).

Purpose of the Study:

• To review current knowledge on endocrine disruption in nematodes.
• To assess the potential of nematodes, particularly Caenorhabditis elegans, as biomonitoring tools for EDCs.

Main Methods:

• Comprehensive literature review on endocrine disruption in nematodes.
• Analysis of existing studies and presentation of novel data.
• Focus on Caenorhabditis elegans as a model organism.

Main Results:

• Evidence suggests that EDCs can impact nematodes at molecular, organismal, and community levels.
• Studies indicate that chemicals defined as EDCs for vertebrates can affect nematodes.
• Caenorhabditis elegans is a prominent species in current research on nematode endocrine disruption.

Conclusions:

• Nematodes, especially C. elegans, are promising candidates for biomonitoring EDCs.
• Further mechanistic studies on nematode hormonal processes are needed.
• Understanding endocrine disruption in nematodes is vital for aquatic ecosystem health assessment.
