- Abstract
- Pancreatic beta-cell loss represents a key factor in the pathogenesis of diabetes. Since the influence of purinergic signaling in beta-cell apoptosis has not been much investigated, we examined the role of the ADP receptor P2Y(13) using the pancreatic insulinoma-cell line MIN6c4 as a model system. Real time-PCR revealed high expression of the ADP receptors P2Y(1) and P2Y(13). Adding the ADP analogue, 2MeSADP, to MIN6c4 cells induced calcium influx/mobilization and inhibition of cAMP production by activation of P2Y(1) and P2Y(13), respectively. 2MeSADP reduced cell proliferation and increased Caspase-3 activity; both these effects could be fully reversed by the P2Y(13) receptor antagonist MRS2211. We further discovered that blocking the... (More)

We further discovered that blocking the P2Y(13) receptor results in enhanced ERK1/2, Akt/PKB and CREB phosphorylation mechanisms involved in beta-cell survival. These results indicate that P2Y(13) is a proapoptotic receptor in beta-cells as the P2Y(13) receptor antagonist MRS2211 is able to protect the cells from ADP induced apoptosis. (Less)
