Secretory pattern of growth hormone regulates plasma concentration of pregnancy-associated murine protein-1 in the non-pregnant rat

in Reproduction

Summary. Serum concentrations of pregnancy-associated murine protein-1 (PAMP-1) were followed in hypophysectomized adult female rats during treatment with oestradiol and continuous or intermittent human growth hormone (hGH). After hypophysectomy a rapid decrease in PAMP-1 values was recorded while concentrations of albumin and the acute phase α2-macroglobulin were unaffected. PAMP-1 values were completely restored by continuous infusion of hGH (1·4 i.u./kg/day). Neither the same dose of hGH given as two daily injections nor oestrogen replacement treatment had any effect. It is concluded that the serum concentration of PAMP-1 in the non-pregnant rat is regulated by the sexually dimorphic secretory pattern of GH.
