Pesticide-related environmental contamination has emerged as a significant global issue, endangering human, wildlife, and vegetation health. N-phosphonomethyl-glycine, or GLY, is aherbicide commonly utilized worldwide. Due to being in the category of organophosphorus compounds, it is known for its neurotoxic effects. This study used a transgenic C. elegans Alzheimer's Disease (AD) model to examine the neurological effects of glyphosate. In the CL4176 (C. elegans) AD model, it has been demonstrated that glyphosate exacerbates amyloidbeta (1-42) toxicity through several mechanisms and due to these mechanisms, it includes increased lethality, behavioral changes, and elevated levels of amyloid-beta protein. Exposure to C. elegans at different glyphosate concentrations (12, 15, 18.5, 20, and 25mg/L) for 24 hours resulted in a concentration-dependent reduction of behavioral parameters such as body bend, head thrash, body length, and pharyngeal pumping.Furthermore glyphosate exposure at these concentrations increased oxidative stress, as evidenced by decreased catalase enzyme activity in the C. elegans AD model. Additionally, a significant increase in amyloid-beta(Aβ (1-42)) protein expression was observed in theC.elegans CL4176 AD strain treated with glyphosate. In conclusion, glyphosate appears to promote AD-like characteristics and warrants further investigation into its potential role in neurodegeneration.
