Highlights • Diazinon perturbs CNS function via multiple mechanisms. • Oxidative stress is one of the main causes of diazinon-induced neurodegeneration. • Gene expression may be affected by diazinon exposure. • Diazinon administration may increase anxiety and depressive-like behaviors. • Spatial learning and short and long-memory are severely affected by diazinon.
Diazinon (DZN) with prominent neurotoxic effects perturbs CNS function via multiple mechanisms. This investigation intends to explore mood, spatial learning, and memory dysfunction, acetylcholine esterase (AChE) activity, and neurodegeneration-related gene expression in the cortex and hippocampus regions of mice exposed to DZN for 63 consecutive days (subchronic exposure). Adult male albino mice were orally given sublethal DZN (DZNL = 0.1 mg/kg, DZNM = 1 mg/kg and DZNH = 10 mg/kg). All mice in the DZNH group died within 3 weeks postexposure. DZNL and DZNM caused body and brain weight loss (p
