Abstract:
:The effects of P2Y2 purinoceptor activation on c-Fos expression and the signaling pathways evoked by extracellular ATP/UTP in HeLa cells were investigated. We found that P2Y2 activation induced c-Fos protein and phosphorylated the extracellular signal-regulated kinases 1 and 2 (ERK1/2). The P2Y2-stimulated c-Fos induction was partly blocked (a) by U73122, a phospholipase C inhibitor, (b) by Gö6976, a conventional PKC inhibitor, (c) by PD098059, a mitogen-activated protein kinase kinase inhibitor, and, moreover, (d) by the inhibitors of phosphoinositide 3-kinases (PI3K), LY294002 and wortmannin. When Gö6976 and PD098059, or Gö6976 and wortmannin, were combined there was a totally inhibition of P2Y2-induced c-Fos increase. Either U73122 or Gö6976 did not inhibit ERK1/2 phosphorylation induced by ATP/UTP, while it was inhibited by LY294002 (or wortmannin) and by staurosporine. Additionally, wortmannin inhibited the cytosol-to-membrane translocation of PKC- epsilon induced by ATP/UTP. These data indicated that agonist-induced PI3K and downstream PKC- epsilon activation mediated the effect of ATP/UTP on ERK1/2 activation. To test the biological consequences of ERK1/2 activation, the effect of P2Y2 on cell functions were examined. P2Y2 stimulation increased cell proliferation and this effect was attenuated by PD098059 in a dose-dependent manner, thereby indicating that the ERK pathway mediates mitogenic signaling by P2Y2. In conclusion, the activation of conventional PKCs through P2Y2 receptor acts in concert with ERK and PI3K/PKC- epsilon pathways to induce c-Fos protein and HeLa cell proliferation.
