From Genes to Organs: A Multi-Level Neurotoxicity Assessment Following Dietary Exposure to Glyphosate and Its Metabolite Aminomethylphosphonic Acid in Common Carp (Cyprinus carpio)

Popis výsledku v původním jazyce

Herbicide glyphosate and its main metabolite, aminomethylphosphonic acid (AMPA), have raised concerns due to their potential neurotoxicity in non-target aquatic species. This study evaluated neurotoxic effects in common carp (Cyprinus carpio) following a 28-day dietary exposure to glyphosate (325.2 and 3310.0 μg/kg) and AMPA (335.2 and 3441.0 μg/kg) at two concentrations, including control and four treatment groups. Brain acetylcholinesterase activity was significantly (p < 0.05) reduced in all exposed groups, while muscle acetylcholinesterase activity remained unchanged. Brain dopamine was significantly (p < 0.05) decreased only in the highest AMPA group. Plasma butyrylcholinesterase activity increased significantly (p < 0.05) in the low-dose glyphosate group. The level of mRNA expression of ache was significantly (p < 0.05) downregulated in the brain across all treatments and upregulated in the gills only at the highest AMPA concentration. Histological analysis of the brain revealed vascular congestion in both glyphosate-exposed groups, indicating pathological changes. These results suggest that dietary exposure to glyphosate and AMPA can affect cholinergic and dopaminergic pathways in fish, with the brain being a particularly sensitive target tissue. Our findings contribute to understanding the potential neurotoxic risks posed by glyphosate-based compounds in aquatic environments.
