EEF2 and spindle cell hemangioma: Pretreatment of the cells with SCH23390, a D1 receptor antagonist, blocked the D1 receptor-induced dephosphorylation of eEF2 (Figure 1A; SKF 15 min vs. SKF 15 min +SCH, p = 0.003; SKF 60 min vs. SKF 60 min +SCH, p = 0.04), while pretreatment with D2 receptor antagonist, eticlopride, did not have any effect (Figure 1B; one-way ANOVA, F(7,36) = 0.828, p = 0.57).
