Zusammenfassung: | •PROTO showed improvement in visual and motor function ability in rat model.•PROTO increases nuclear expression of Nrf2 and its transcriptional activity in SH-SY5Y cells.•PROTO showed neuroprotective effects against PD.
Parkinson’s disease (PD) is the most widespread motor-affecting disease affecting majorly middle- and late age population. Thus, in the current study, we intended to explore the neuroprotective effect of protodioscin (Proto) against 6-hydroxydopamine (6-OHDA)-induced PD rat model.
After induction of PD with the injection of 6-OHDA, the different dose of Proto was administered for the duration of experimental protocol (2 months). We have scrutinized the consequence of Proto on the cognitive behaviours via Moris water maze (MWM), and recognition of novel objects and its location tasks. The effect of Proto was also investigated on the expression of Nrf2 in human neuroblastoma SHSY5Y cells via western blot analysis.
The results showed significant decrease in travelled distance as compared by the lesion treated group. Further significant difference was revealed in the latency time to detect the platform that is visible and it confirmed that, there were no noteworthy dissimilarity was observed in the visual and motor function ability. The result also suggests that, the activation of Nrf2 is the possible mechanism of neuroprotection of Proto against PD.
As a concluding remark, the present study confirmed the neuroprotective role of Proto against PD both in in vitro and in vivo models. |
