Pigs exposed to valproic acid (VPA) during embryonic development exhibit autism spectrum disorder (ASD) traits. This pig model shows behavioral and neuroanatomical changes relevant to ASD, offering a promising research alternative.
Area of Science:
- Neuroscience
- Developmental Biology
- Animal Models
Background:
- Cost-effective and disease-relevant animal models are crucial for biomedical research.
- Autism spectrum disorder (ASD) research requires suitable models to understand its complex mechanisms.
Purpose of the Study:
- To investigate the feasibility of using pigs as a model for autism spectrum disorder (ASD).
- To assess the behavioral and neuroanatomical effects of embryonic valproic acid (VPA) exposure in pigs.
Main Methods:
- Bama miniature pigs were exposed to valproic acid (VPA) during critical embryonic stages.
- Behavioral assessments were conducted to evaluate gait, anxiety, learning, and social patterns.
- Neuroanatomical analysis of cortical regions and transcriptome analysis of the prefrontal cortex were performed.
Main Results:
- VPA-exposed pigs displayed abnormal gait, increased anxiety, impaired learning, and altered social patterns.
- Significant neuroanatomical changes were observed in cortical regions, including malformations and altered neuronal structures.
- Gene expression analysis revealed significant alterations in ASD-linked genes, particularly in the dopamine signaling pathway.
Conclusions:
- Pig models exposed to VPA during embryonic development exhibit key behavioral and neuroanatomical features relevant to ASD.
- This model offers a potentially more ethical and effective alternative to rodent or primate models for neurodevelopmental disorder research.
- The findings highlight the utility of pigs in studying the neuropathological and molecular mechanisms underlying ASD.
