Abstract :
[en] Hypoglycin A (HGA) and methylenecyclopropylglycine (MCPrG) are protoxins produced
by Sapindaceae plants, particularly Acer pseudoplatanus, and are responsible for causing
atypical myopathy (AM) in equids. These protoxins metabolise into toxic compounds, such as
methylenecyclopropylacetyl-CoA (MCPA-CoA), which alters energy metabolism and induces severe rhabdomyolysis. Currently, no specific treatment exists for this poisoning, in vitro models fail to reproduce HGA’s toxic effects on equine primary myoblasts, and mammalian models are impractical for large-scale drug screening. This study aimed to develop a zebrafish embryo model for screening therapeutic compounds against AM.
