Precocious development of cytochrome P-450 in neonatal rat liver after glucocorticoid treatment.


ABSTRACT: Intraperitoneal injection of neonatal rats with glucocorticoid hormones causes precocious development of hepatic cytochrome P-450. Glucagon injection fails to stimulate this cytochrome P-450 development. Adult liver cytochrome P-450 is less responsive to glucocorticoid stimulation than is that of neonatal rat liver. Adrenalectomy of prematurely delivered neonatal animals prevents the early postnatal development of cytochrome P-450. Glucocorticoids failed to increase cytochrome P-450 concentrations in foetal rat liver. These findings imply that, although glucocorticoids are mandatory regulatory factors controlling cytochrome P-450 development, they are not themselves the 'trigger' initiating onset of that development.
