NGF and PI3K/Akt signaling participate in the ventral motor neuronal protection of curcumin in sciatic nerve injury rat models

摘要

Objective: It has been reported that sciatic nerve injury (SNI) leads to degeneration, damage, and apoptosis of motor neurons. Nerve growth factor (NGF) plays a pivotal role in regeneration and reestablishment of neuronal function via activating PI3K/Akt survival signaling pathways. Curcumin owns neuroprotective effect following brain injury. In the present study, we attempt to investigate underlying mechanism of neuroprotective effect of curcumin through elucidating its correlation with NGF and PI3K/Akt signaling pathways in vitro and in vivo.
