Wm and GSK-A1 induced inhibition of PRL release are not caused by loss of intracellular PRL content and inhibition of PRL gene (Prl) expression. (A) Time course of Wm- (top) and GSK-A1 (bottom) induced inhibition of basal PRL release. (B) Time course of Wm (top) and GSK-A1 (bottom) induced accumulation of intracellular PRL content. (C) Lack of effects of Wm (top) and GSK-A1 (bottom) on Prl expression in cultured anterior pituitary cells. The experiments were performed in static incubation of cultured anterior pituitary cells: 0.25 million/well (A, B) and 1.5. million/well (C). Data points shown are mean ± SEM of sextuplicate incubation; *P < 0.002 between pairs.
