Effects of the protein tyrosine kinase inhibitor, herbimycin A, on prolactin gene expression in GH3 and 235-1 pituitary tumor cells.


The high basal level of prolactin (PRL) gene expression in rat pituitary GH3 cells is maintained through the spontaneous activity of voltage-sensitive calcium channels (VSCCs). This can be observed experimentally by addition of 0.5 mM CaCl2 to GH3 cells cultured in a low calcium, serum-free medium. CaCl2 specifically induces PRL gene expression and this… (More)
