IntroductionParkinson's disease (PD) is a neurodegenerative disorder majorly associated with movement and behavioral disturbances. Pathologically, the loss of dopaminergic (DA) neurons triggered by the deposition of α-synuclein (SNCA) leads to the decrease in dopamine levels affecting motor and cognitive functions of the brain. Current pharmacotherapy for PD only addresses its symptoms but is not able to halt its progression. Traditional medicines are being increasingly used for the treatment of neurodegenerative disorders.AimThe present study investigated the effects of Neurogrit Gold (NG), a herbo-mineral prescription medicine, on a Parkinson's model of Caenorhabditis elegans.MethodsChemical characterization of NG was performed on HPLC and GC-MS/MS platforms. Evaluation of NG was done in the neurotoxicant 6-OHDA-induced N2, BZ555, and NL5901 strains of C. elegans.ResultsIt was observed that NG treatment did not hamper the lifespan, survival, and progeny development of C. elegans strains. The worms treated with NG were able to resist the deleterious effects of 6-OHDA on survival, progeny development, body bends, and chemotaxis in N2 and DA neuron degeneration in BZ555 worms. In NL5901 worms, NG treatment reduced SNCA aggregation, restored lipid content, as well as improved body bends, chemotaxis, and food uptake. Gene expression studies on 6-OHDA exposed and NG-treated N2 worms suggest that the neuroprotective effects of NG stem from its ability to regulate genes involved in mitochondrial autophagy (pink-1, pdr-1); dopamine synthesis (cat-2); redox (sod-3) and protein folding homeostasis (hsf-1, hsp-12.3).ConclusionNeurogrit Gold has robust neuroprotective effects, making it a suitable treatment option against etiologies of Parkinson's disease.
