Protective effect of uric acid against 6-OHDA-induced injury in SH-SY5Y cells
Molecular Neurodegeneration volume 7, Article number: S12 (2012)
To investigate the effect of uric acid (UA) on 6-hydroxydopamine (6-OHDA) -induced injury in SH-SY5Y cells.
The cell viability was measured by the MTT reduction assay. The cell apoptosis was assessed by Hoechst 33342 staining with fluorescence microscopy. The phophorylation of Akt and GSK-3β(ser9) was determined by Western blot analysis.
Treatment with 6-OHDA at 50µM for 12 h significantly decreased the viability of SH-SY5Y cells. Pretreatment with UA (200-400µM, 0.5h) prior to 6-OHDA treatment markedly increased the cell viability of SH-SY5Y cells, as compared to that of 6-OHDA-treated group. The beneficial effects of UA against 6-OHDA-induced apoptosis were also confirmed by Hoechst 33342 staining assay. Moreover, 6-OHDA decreased the Akt activity and increased the GSK-3β activity, which could be blocked by UA (200-400µM) pretreatment.
These data suggest that 6-OHDA-induced cell injury was attenuated by UA. The underlying mechanisms may involve the up-regulation of Akt and the reduction of GSK-3β activity.
