Fig. 3. Effect of Ca²⁺-mobilizing agents on IP₃R1 redistribution. The percentage of cells with a perinuclear IP₃R1 is depicted before and after incubation with AVP (3 µM), thapsigargin (1 µM) and CPA (50 µM) for 5 hours. Each result is the mean±s.e.m. from three independent experiments. *Significantly different from the control.
