ABSTRACT
Objective To investigate the protective effects of memantine on isofluane ̄induced decrease of proliferation in neural stem cells ( NSCs) and the potential mechanisms in vitro. Methods Neural stem cells were isolated from rat hippocampi (postnatal day 1) and grew in culture. Cultured NSCs were randomly divided into the control ( Group Control), Vehicle (Group Vehicle), Isoflurane ( Group Iso), Isoflurane +Memantine ( Group Iso +Mem) and Isoflurane + Memantine +LY294002 groups (Group Iso+Mem+LY).Proliferation was assessed by cell counting and BrdU incorporation.Western blot was conducted to detect protein expression of phospho ̄Akt. Results Compared with the control group,BrdU incorporation and phospho ̄Akt expressions in neural stem cells significantly declined after 2.4% isoflurane exposure for 6 h (P<0.01).However, isofluane ̄induced decrease of BrdU incorporation and phospho ̄Akt expressions was attenuated by the treatments of memantine (P<0.01)). It was showed that Akt inhibitors LY294002 reversed the protective effects on neural stem cells proliferation by memantine(P<0.01). Conclusion The results suggest that memantine treatment might attenuate isofluane ̄induced decrease of proliferation in neural stem cells via Akt signaling pathway.
