“…The present results also show the zebrafish cholinergic dynamics following STX exposure, as we observed an upsurge in ache mRNA levels at both 144-h of exposure with 10 and 100 μg/L STX, while 1 μg/L only at 168-h of exposure. This trend aligns with literature denoting an imbalanced ache and chat dynamic, leading to augmented ACh neurotransmitter concentrations, presenting potential genotoxic effects [ 39 ]. Further evidence also underscores that extended STX exposure augments malondialdehyde levels in larvae and induce a lipid peroxidation.…”
