FIGURE 7.

Effect of Vasopressin receptors on cell viability. Cells were left under basal conditions or treated as described in the methods section and were stained with crystal violet solution. Treatment with 100 nM dDAVP significantly reduced cell viability compared with untreated cells. The same effect was observed in cells treated with 100 nM dDAVP and 100 nM tolvaptan for 72 h. In contrast, stimulation with 100 nM SR49059 did not affect dDAVP cell viability. Data are presented as means ± S.E.M. of six independent experiment and analyzed by one-way ANOVA followed by Dunnett’s Multiple Comparison test (**p < 0.01 and ***p < 0.001 vs. untreated; ^### p < 0.001 and ^#### p < 0.0001 vs. DMSO).
