Abstract
Ropinirole, a D2/D3 receptor agonist has been reported to have neuroprotective effects. We showed that ropinirole can prevent rotenone-induced apoptosis in dopaminergic cell line SH-SY5Y through D3 receptor. We found that ropinirole can block the rotenone-induced phosphorylation of JNK, P38 and p-c-Jun, but promote the phosphorylation of ERK1/2. Furthermore, we demonstrated that ropinirole can reduce the rotenone-induced cleavages of caspase 9, caspase 3 and PARP and elevate the expression of anti-apoptotic proteins of p-Akt and bcl-2. These results provide a basis for neuroprotection by this drug for the treatment of Parkinson disease.
