Abstract:

Methyl mercury is a teratogenic and neurodevelopmental toxicant in the environment. MeHg affects several biological pathways critical for brain development. The present study validated the effect of Fisetin on developmental MeHg exposure induced alterations in mitochondrial apoptotic pathway and Rho GTPase mRNA expressions in hippocampus of Fgeneration rats. Pregnant Wistar rats were grouped as Group I : administered with vehicle control, Group II: MeHg (1.5 mg/kg b.w), Group III: MeHg + Fisetin (10 mg/kg b.w), Group IV: MeHg + Fisetin (30 mg/kg b.w), Group V: MeHg + Fisetin (50 mg/kg b.w), Group VI: MeHg + Fisetin (70 mg/kg b.w), Group VII: Fisetin (30 mg/kg b.w) alone. Fisetin reduced mercury accumulation in offspring brain. In hippocampus, Fisetin preserved mitochondrial total thiol status, glutathione antioxidant system, mitochondrial metabolic integrity and respiratory chain activity. Fisetin ameliorated apoptotic signals by preventing Cytochrome c release, down regulating ERK 1/2 and Caspase 3 gene expression. Fisetin also upregulated mRNA expressions of RhoA/Rac1/Cdc42 in hippocampus. Predominant effect of Fisetin was to reduce mercury accumulation in offspring brain there by diminishing the toxic effect of MeHg. Hence we showed that, gestational intake of Fisetin (30 mg/kg b.w.) impedes developmental MeHg neurotoxicity by regulating mitochondrial apoptotic and Rho GTPase signalling molecules and by reducing the mercury accumulation in hippocampus of Fgeneration rats.
