Özet

Aim: In the present study, we investigated whether Erythropoietin (Epo) has a protective effect against cytotoxicity and apoptotic cell death induced by 6-hydroxydopamine (6-OHDA) in PC12 cell line cultures. Material and Methods: Epo exerted significant protective effect against 6-OHDA-induced cell injury and apoptosis as confirmed by lactate dehydrogenase cytotoxicity assay, anti-single strand DNA immunostaining and annexin-V staining. Results: Epo significantly decreased 6-OHDA-induced DP5 pro-apoptotic protein mRNA expression and increased bcl-XL anti-apoptotic protein mRNA expression. Any effect of Epo on CREB transcription factor phosphorylation was not observed. Conclusion: These results suggest that Epo exerts neuroprotective effect against 6-OHDA-induced cell death at least partially via the differential regulation of the expression of genes involved in the apoptotic process.
