title: Effect of TGF beta on liver genes expression. Antagonistic effect of TGF beta on IL-6-stimulated genes in Hep 3B cells.
abstract: The effect of transforming growth factor beta (TGF beta) on the expression of a group of liver genes has been investigated in the hepatoma cell line Hep 3B. TGF beta induces a decrease of the basal level of apolipoprotein A-II (ApoA-II), retinol binding protein (RBP) and alpha-fetoprotein (alpha Fp). Furthermore, TGF beta efficiently antagonizes the IL-6-induction of hemopexin (Hpx) and haptoglobin (Hp) and alpha 1-acid glycoprotein (AGP). These effects of TGF beta are apparently mediated by post-transcriptional mechanism(s). These findings, together with previously reported data on the inhibitory effect of TGF beta on acute phase genes (e.g. ApoA-I and albumin), suggest a role for TGF beta in the regulation of expression of liver genes.
