Human hepatocellular carcinomas (HCCs) show resistance to apoptosis mediated by several death receptors. Because cellular FLICE/caspase-8-inhibitory protein (cFLIP) is a recently identified intracellular inhibitor of caspase-8 activation that potently inhibits death signaling mediated by all known death receptors, including Fas, TNF-receptor (TNF-R), and(More)
We have recently demonstrated that immunization with hepatitis C virus-like particles (HCV-LPs) generated in insect cells can elicit both humoral and cellular immune responses in BALB/c mice. Here, we evaluate the immunogenicity of HCV-LPs in HLA2.1 transgenic (AAD) mice in comparison to DNA immunization. HCV-LP immunization elicited a significantly(More)
In most adult humans, hepatitis B is a self-limiting disease leading to life-long protective immunity, which is the consequence of a robust adaptive immune response occurring weeks after hepatitis B virus (HBV) infection. Notably, HBV-specific T cells can be detected shortly after infection, but the mechanisms underlying this early immune priming and its(More)
The incidence of hepatocellular carcinoma (HCC) tends to decrease in sustained responders (SR) to interferon (IFN) therapy for chronic hepatitis C rather than in non-responders (NR). However, some SR develop HCC and their details and prognosis are not well-known, so we investigated such cases. Among 462 patients who underwent IFN therapy and were available(More)
Des-gamma-carboxy prothrombin (DCP) is a well-established tumor marker for hepatocellular carcinoma (HCC), but the precise mechanism by which HCC cells produce DCP remains unknown. Our preliminary experiments demonstrated that HepG2 cells with chemical induction of epithelial-to-fibroblastoid conversion (EFC) produced DCP through impairment of vitamin K(More)
Type 2 diabetes mellitus (T2DM) is an established independent risk factor for hepatocellular carcinoma (HCC). T2DM is associated with non-alcoholic steatohepatitis (NASH), which is a major cause of non-HBV and non-HCV-related HCC; nevertheless, it has been difficult to identify those patients with T2DM who have a high risk of developing HCC. The aim of this(More)
AIM To evaluate the clinical utility of serum fibrosis markers, including YKL-40, in patients with HCV-associated liver disease. METHODS A total of 109 patients with HCV-associated liver disease were enrolled. We measured serum type IV collagen, amino-terminal peptide of type III procollagen (PIIIP), hyaluronic acid (HA), YKL-40 levels and biochemical.(More)
In recent years, partial splenic embolization (PSE) has been widely used in patients with cirrhosis and hypersplenism caused by portal hypertension. We investigated the complications associated with PSE cases seen in our hospital. Seventeen cases of liver cirrhosis that had undergone PSE were examined to investigate the complications associated with it.(More)
Currently, pyogenic liver abscess is not frequent, but it is a severe infectious disease. However a strategy for the effective treatment of liver abscess is not established. We analyzed 75 cases of liver abscess over an eight year period and evaluated their prognosis, any associated underlying disease, or the effect of percutaneous transhepatic abscess(More)
BACKGROUND The efficacy of continuous arterial infusion chemotherapies via a subcutaneously implanted port has been reported in unresectable HCC cases. However, the regimens for this therapy are still controversial. Among these regimens, cisplatinum (CDDP) + 5-fluorouracil (5-FU) or epirubicin have been reported to have favorable effects.
