Mallotus oblongifolius extracts ameliorate ischemic nerve damage by increasing endogenous neural stem cell proliferation through Wnt/β-catenin signaling pathway

Abstract

Abstract Mallotus oblongifolius (MO), an edible medicinal plant from Hainan in China, exerts a wide range of bioactivities. The daily consumption of MO or its extracts has been observed to ameliorate ischemic nerve injury. However the mechanisms remain unclear. In this study, the effects of MO in both in vitro and in vivo were investigated. The results indicated that MO improved the motor ability, neurosensory ability, balance and grasping ability of mice with ischemic injuries, induced by bilateral common carotid artery ligation (BCCAO). In addition, MO improved the morphology of neurons, resisted the loss of neurons, and enhanced the content of nestin protein in cerebral cortex and subgranular zone (SGZ) area. Furthermore, in the oxygen–glucose deprivation and re-perfusion(OGD/R) treated cell model, MO could effectively activate Wnt/β-catenin signaling pathway and promote the proliferation of neural stem cells (NSCs) and increase the protein expression levels of β-catenin and Cyclin D1. Our results suggest that Mallotus oblongifolius may be used as a nutraceuticals or functional foods to alleviate ischemic nerve damage and promote the recovery of ischemic stroke.
