Chen S, Zhang X, Yang D, Du Y, Li L, Li X, Ming M, Le W: D2/D3 receptor agonist ropinirole protects dopaminergic cell line against rotenone-induced apoptosis through inhibition of caspase- and JNK-dependent pathways. FEBS Lett. 2008 Mar 5;582(5):603-10. Epub 2008 Jan 31.
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. |
