Significance of des-gamma-carboxy prothrombin production in hepatocellular carcinoma.
Serum des-gamma-carboxy prothrombin (DCP) is commonly used to detect hepatocellular carcinoma (HCC). This review focuses on the clinical features of DCP-positive HCC and the molecular function of DCP in HCC. DCP-positive HCC demonstrates more aggressive clinicopathological features than DCP-negative HCC. Analysis of the biological effects of DCP revealed that DCP acts as a growth factor in both...
متن کاملVitamin K and the biosynthesis of prothrombin. V. Gamma-carboxyglutamic acids, the vitamin K-dependent structures in prothrombin.
Tryptic peptides obtained from normal prothrombin have been compared with those obtained from prothrombin synthesized by cattle given the vitamin K antagonist dicumarol. Two peptides were found which contain vitamin K-dependent structures. These peptides contain residues 4 through 10 and residues 12 through 44, respectively. One of these (residues 4 through 10) has previously been shown to cont...
متن کاملDes-gamma-carboxy prothrombin (DCP) antagonizes the effects of gefitinib on human hepatocellular carcinoma cells.
BACKGROUND/AIMS Des-gamma-carboxy prothrombin (DCP), an aberrant prothrombin produced by hepatocellular carcinoma (HCC) cells, is known as a marker for HCC. Recent studies indicated that high levels of DCP are associated with the malignant potential of HCC. In this study, we aimed to investigate the association of DCP with gefitinib treatment failure in HCC and whether DCP counteracts gefitinib...
متن کاملVitamin K and the Biosynthesis of Prothrombin
Highly purified dicoumarol-induced bovine prothrombin, which does not bind calcium ions and has no prothrombin activity, has been structurally compared with normal prothrombin. Quantitative amino acid and carbohydrate analysis gave identical results for both prothrombins, as did analysis of the NHz-terminal and the COOH-terminal amino acids and molecular weight determination with the sodium dod...
