Dose-related stimulation of intracellular cAMP production in HepG2 cells by VIP. HepG2 cells were 80% confluent at the time of treatment. Cells were treated with VIP (10−8, 10−7 and 10−6 M) for 10 minutes at 37°C. Intracellular cAMP was measured at by using cAMP RIA kit from Perkin Elmer. Data is expressed as the mean ± SEM, N = 3; ***ρ< 0.001 for VIP (10−7M and 10−6M) versus untreated cells.
