| Research Abstract |
In the present study, we investigated the cytoprptective effects of tocotrienol (T3) in cellular and murine Parkinson's disease (PD) models. All T3 homologues exerted cytoprptective effects via activation of PI3K/Akt signaling pathway in a cellular PD model. We also identified estrogen receptor (ER) beta as an upstream mediator of PI3K/Akt signaling and demonstrated the direct binding of T3 to ER beta in vitro. Furthermore, we revealed that T3 treatment relieved PD-related symptoms in PD model mice.
Our data have demonstrated that T3 elicits the cytoprotective effects via ER beta/PI3K/Akt signaling pathway in cellular and murine PD models.
