Liver architecture remodeling following partial hepatectomy (PHx) involves the formation of a complex network of liver sinusoids through which the blood flows. The present study examines the involvement of vascular endothelial growth factor (VEGF) and angiopoietin-1 (ang-1) during liver regeneration. Following PHx, VEGF and ang-1 mRNA levels increase,(More)
BACKGROUND/AIMS Hepatic fibrosis involves excess deposition of extracellular connective tissue of which collagen type I fibers form the predominant component. Left untreated it develops into cirrhosis, often linked with hepatocellular carcinoma. Owing to the fact that cirrhotic liver regeneration is impaired, resection of hepatocellular carcinoma associated(More)
Advanced hepatic fibrosis is characterized by excessive extracellular matrix deposition, where collagen and proteoglycans are the main constituents of scar tissue. In previous studies, we showed that heparanase, a heparan sulfate-degrading enzyme, and vascular endothelial growth factor (VEGF) play an important role during liver development and remodeling.(More)
Heparan sulphate proteoglycans are major components of the liver extracellular matrix. Their cleavage by heparanase (endo-beta-glucuronidase) may thus be involved in liver-specific normal and pathological processes. Heparanase mRNA and protein were expressed during liver development but not in the mature healthy liver. A biphasic gain of heparanase(More)
