| Summary: | Emodin (EMO) possesses extensive pharmacological activities, which has been proven to exert the protective impact in diverse nervous system diseases. Nonetheless, whether EMO emerges a neuro-protective activity in hypoxic-evoked ischemic brain injury is still further probed. The intention of the research is to disclose whether EMO emerges neuro-protective activity in hypoxic-evoked ischemic brain injury. PC-12 received hypoxia administration, and then cell viability, apoptosis and autophagy were estimated. After EMO disposition, the above-involved cellular processes were evaluated again. MiR-25 functions in EMO-affected cells were also estimated. The interrelation between miR-25 and neurofilament light-chain polypeptide gene (NEFL) and the conceivable roles of NEFL in hypoxia-disposed cells were investigated. The latent mechanism was uncovered by mTOR and Notch pathways determination. Hypoxia triumphantly triggered apoptosis and autophagy, but EMO repressed these functions in PC-12 cells. Increased miR-25 was induced by EMO, and inhibited miR-25 abated the impacts of EMO on hypoxia-disposed PC-12 cells. NEFL as a neoteric target gene of miR-25 was predicated, and overexpressed NEFL annulled the functions of EMO in hypoxia-injured cells. EMO activated mTOR and Notch pathways through repressing NEFL. The investigations corroborated that EMO weakened hypoxia-triggered injury via elevating miR-25 by targeting NEFL in PC-12 cells. |
