Protective Effect of Ferulic Acid on PC12 Cells with H2O2-induced Oxidative Damage
To investigate the protective effect of ferulic acid on PC12 cells injured by H
2
O
2
and the molecular mechanisms.
Method:
2
The oxidative stress model was established by treating PC12 cells with H
2
O
2
and then different dosages of ferulic acid (1
10
100 μmol·L
-1
) were used for intervention. Methyl thiazolyl tetrazolium (MTT) assay was used to evaluate the cell viability
lactate dehydrogenase (LDH) and malondialdelyde (MDA) in cell supernatant
and superoxidedismutase (SOD) in cells was tested by biochemical method respectively. Insulin-like growth factors-1 (IGF-1) mRNA and protein expressions were detected by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot.
Result:
2
The 24 h intervention with different dosages of ferulic acid (1
10
100 μmol·L
-1
) could significantly improve the oxidative damage of PC12 cells induced by H
2
O
2
compared with the model group
ferulic acid at 1
10
100 μmol·L
-1
significantly increased PC12 cells viability
significantly decreased LDH and MDA content in cell supernatant (
P
<
0.05
P
<
0.01)
and enhanced SOD activity(
P
<
0.01). Real-time PCR and Western blot showed that compared with control group
IGF-1 mRNA and protein expressions in model group decreased significantly (
P
<
0.01)
compared with model group
IGF-1 mRNA and protein expressions in ferulic acid group increased significantly (
P
<
0.01).
Conclusion:
2
Ferulic acid exerts a protective effect on H
2
O
2
-inducing PC12 cells injury
which might be related to insulin signaling pathways.
