Using human hepatoblastoma cells (Hep G2) as an in vitro model system, this study examined the effect of albumin and fatty acids on the synthesis, secretion, and the steady-state mRNA expression of apo AI and AII.
Albumin mRNA was detected in 22 of 23 hepatocellular carcinomas (96%); all hepatoblastomas, hepatocellular adenomas, and focal nodular hyperplasias; and within the hepatoid areas of an extrahepatic malignant mixed germ cell tumor.
When evaluated in human hepatoblastoma-derived (Hep G2) cells exposed to different doses of the recombinant human cytokine for variable time intervals, IL-6 caused a dose- and time-dependent decrease in the secretion of [35S]methionine-labeled TBG, transthyretin (TTR), and albumin.
