ABSTRACT
AIM To study the adaptive cytoprotection of H 2O 2 preconditioning against oxidative stress damage in PC12 cell and the relationships between brain derived neurotrophic factor (BDNF) and the adaptive cytoprotection of H 2O 2 preconditioning. METHODS The viability of PC12 cells was evaluated by MTT assay. Apoptosis was detected by PI stain flow cytometer. Expression of BDNF was analyzed by immuo flow cytometer. RESULTS After H 2O 2 preconditioning, the survival of PC12 cells exposure to H 2O 2 (20~60 ?mol?L -1 ) was increased and the apoptosis of PC12 cells induced by H 2O 2 (20 or 30 ?mol?L -1 ) was inhibited and the expression of BDNF in PC12 cells was enhanced. CONCLUSION H 2O 2 preconditioning is protective against the damage of PC12 cells induced by H 2O 2 and its mechanisms may involve up modulation of the expression of BDNF.
