we report here that this gh responsive protein [ 39,000-45,000 mol wt ( mr ) ] can be induced ( 7-fold ) by infusion of igf-i in hypophysectomized rats or ( 3.5-fold ) in protein-deprived rats , whereas two other forms of igf-bp ( e.g . 31,000-34,000 and 24,000 mr ) showed no change in the hypophysectomized animals and minimal increases in the protein-deprived animals .
