IGF-I inhibited tumorous GH in 62% and stimulated PRL secretion in 71% of tumours over 4 days, without affecting alpha-subunit secretion or being mitogenic for somatotrophinoma cells in vitro. No hormonal effects were observed over short (4-hour) incubations. IGF-I may be a newly recognized factor directly stimulating tumorous PRL secretion.
