Prolactin stimulates a hepatotrophic response similar to that caused by phorbol esters or partial hepatectomy in rats. Since phorbol esters, which activate protein kinase C, mimic prolactin action in liver, the relationship between prolactin administration and subsequent hepatic protein kinase C translocation was assessed. Prolactin administration rapidly stimulated a 4-fold elevation of membrane protein kinase C activity. The effect of prolactin on hepatic protein kinase C was specific for lactogenic hormones but could be duplicated by phorbol esters. Further, an increase in serum prolactin was demonstrated subsequent to partial hepatectomy and preceding hepatic protein kinase C translocation. Therefore, translocation of hepatic protein kinase C appears important for hepatic proliferation in response to prolactin administration and to partial hepatectomy.

D011388 Prolactin A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

D011493 Protein Kinase C An serine-threonine protein kinase that requires the presence of physiological concentrations of CALCIUM and membrane PHOSPHOLIPIDS. The additional presence of DIACYLGLYCEROLS markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by PHORBOL ESTERS and it is believed that protein kinase C is the receptor protein of tumor-promoting phorbol esters.
