We have characterized the regulation of plasminogen activator inhibitor- 1 (PAI-1) gene expression by phorbol 12-myristate 13-acetate (PMA), serum, and interleukin-1α (IL-1α) in the human hepatoma cell line HepG2. PMA, serum, and IL-1α induced a rapid and transient 28-fold (PMA), 9-fold (serum), and 23-fold (IL-1α) increase in PAI-1 mRNA,...

Hypertriglyceridemia is a metabolic complication of retinoid therapy. In this study, we analyzed whether retinoids increase the expression of apo C- III, an antagonist of plasma triglyceride catabolism. In men, isotretinoin treatment (80 mg/d; 5 d) resulted in elevated plasma apo C-III, but not apo E concentrations. In human hepatoma HepG2 cells...

The influence of in vivo treatment with eugenol on established mutagens was studied to determine whether eugenol has antigenotoxic potential. The effects of eugenol in rats was investigated in the unscheduled DNA synthesis (UDS) assay with established mutagens and the Salmonella typhimurium mutagenicity assay. In addition, the effect of in vitro...

It has previously been shown that lipoprotein lipase (LPL) enhances the binding of low density lipoproteins (LDL) and very low density lipoproteins (VLDL) to HepG2 cells and fibroblasts, up to 80-fold. This increase in binding is LDL receptor-independent and is due to a bridging of LPL between extracellular heparan sulfate proteoglycans (HSPG)...

Addition of sodium butyrate to the culture medium of the human hepatoma cell line Hep G2 resulted in a time- and dose-dependent increase in the secretion of apolipoprotein A-I (apo A-I) and apolipoprotein B100 (apo B100). After a 24 h preincubation period, a 2.4- and 2.2-fold increase in the secretion of apo A-I and apo B100 respectively was...

In man, the plasminogen activator inhibitor 1 (PAI-1) gene codes for two mRNA species, one of 3.2 kilobases (kb) and the other of 2.4 kb. We report that the protein kinase C activating phorbol ester, phorbol 12-myristate-13-acetate (PMA), causes a different induction of the two PAI-1 mRNA species in the human hepatoma cell line, HepG2. Upon...

It has been suggested that besides the LDL-receptor, hepatocytes possess an apo E or remnant receptor. To evaluate which hepatic lipoprotein receptor is involved in VLDL remnant catabolism, we studied the binding of VLDL remnants to HepG2 cells. Native VLDL was obtained from type IIb hyperlipidemic patients and treated with bovine milk...
