Growth hormone stimulates drug-induced porphyrin formation in liver cells maintained in a serum-free medium
S Sassa, DW Golde and CH Li
Human growth hormone and a few other related polypeptide hormones enhanced
porphyrin formation induced by 2-allyl-2-isopropylacetamide in chick embryo
liver cells maintained in a serum-free medium. The stimulatory effect of
human growth hormone on drug-induced porphyrin formation was significant at
10 ng/ml and increased in a dose-dependent manner. Human growth hormone did
not stimulate porphyrin formation in otherwise untreated cultures. These
findings thus demonstrate a potentiating effect of growth hormones on
hepatic porphyrin formation.
