Outline of Final Research Achievements

Liver atrophy was induced right portal vein ligation of wild type mouse. PCNA expression elevated at 6 hour after portal vein ligation and decreased thereafter in ligated liver (atrophic liver). TUNEL stained nuclei in liver cells increased over time. TSP-1 expression in cytoplasm of ligated liver increased since 6 hour after portal vein ligation. cDNA microarray assay was performed on ligated and non-ligated human liver for therapeutic hepatectomy. TSP-1 was most induced among 132 genes in ligated liver than in none ligated liver.
These results show hypoperfusion of portal vein induce TSP-1 expression in hepatocyte and suppress proliferation and induce apoptosis of hepatocyte.
