Figure 2. P2Y receptors-mediated Ca2+ signaling in proliferation or apoptosis of digestive cancer cells.

Figure 2

Stimulation of Gq/G11-coupled P2Y receptor subtypes (P2Y1, P2Y2, P2Y4, P2Y6 and P2Y11) activates PLC/IP3 pathway to induce intracellular calcium release from the endoplasmic reticulum (ER). An increase in intracellular calcium concentrations would increase the proliferation or apoptosis of different digestive cancer cells.
