Figure 7From: Extracellular ATP activates NFAT-dependent gene expression in neuronal PC12 cells via P2X receptorsModel of the proposed pathway by which extracellular ATP activates NFAT in PC12 cells. The results demonstrate the requirement of Ca2+ influx from the extracellular space and the contribution of both calcineurin-NFATc and MEK-ERK1/2 pathways. The scheme also illustrates the inhibitors used for pharmacological characterisation. BTP2 is a blocker of SOCE and inhibits TRPC channels, but its direct molecular target in PC12 cells is not clear.Back to article page
