Exploring the use of animal models in researching endocrine disruptors, this content delves into the significance of rodent and zebrafish studies. It highlights the importance of genetic variability in mouse models, the use of transgenic rodents to investigate biological mechanisms, and the examination of social behaviors and developmental impacts in zebrafish. The complexities of endocrine disruptor actions and regulatory perspectives are also discussed, emphasizing the need for advanced research methods.

Animal models provide a complex, whole-organism context for studying the interactions and effects of endocrine disruptors
Collaborative Cross (CC) and Diversity Outbred (DO) Populations
The CC and DO mouse models offer a broad genetic base that reflects human genetic variability, enhancing the relevance of findings to human health
Advantages and Limitations of CC and DO Mice
While DO mice offer genetic diversity, their inability to produce genetically identical offspring can be a limitation for certain experimental designs
Transgenic rodents, particularly mice, are useful for studying the biological mechanisms affected by endocrine disruptors, but their creation is resource-intensive and can lead to unintended effects
Rodent models, such as prairie and pine voles, are used to study the effects of endocrine disruptors on social behaviors, which can be relevant to understanding conditions like autism spectrum disorder
Zebrafish are a useful model for studying the developmental impacts of endocrine disruptors due to their physiological and genetic similarities to mammals, including humans
The multifaceted nature of endocrine disruptors requires sophisticated experimental designs and analytical approaches to accurately assess their risks and understand their mechanisms of action
The Environmental Protection Agency oversees the Endocrine Disruptor Screening Program, which evaluates chemicals for potential endocrine-disrupting effects
The European Union is working towards establishing clear criteria for identifying endocrine disruptors and proposing strategies to reduce exposure to these substances
