OBJECTIVE Surveillance of cirrhotic patients enables early detection of hepatocellular carcinoma (HCC) and possibly prolongs survival. The aim of this study was to explore whether early-stage HCC can be detected earlier at a specialized department of liver disease than in other institutions. METHODS The study subjects were 574 patients with HCC. Patients(More)
For the identification of susceptibility loci for primary biliary cirrhosis (PBC), a genome-wide association study (GWAS) was performed in 963 Japanese individuals (487 PBC cases and 476 healthy controls) and in a subsequent replication study that included 1,402 other Japanese individuals (787 cases and 615 controls). In addition to the most significant(More)
Macroscopic vascular invasion is known to be a poor prognostic factor in hepatocellular carcinoma (HCC). The aim of this study was to determine the outcomes and predictive factors after hepatic resection for HCC with microvascular invasion (MVI). One hundred ten patients who underwent curative resection for HCC without macroscopic vascular invasion were(More)
Glucose intolerance frequently is found in hepatocellular carcinoma (HCC) patients with hepatitis C virus (HCV) infection; however, the significance of glucose intolerance remains unclear. In addition, SH2 domain-containing inositol phosphatase (SHIP) 2 is a negative regulator of intracellular insulin signaling; however, changes in SHIP2 expression have not(More)
Anti-gp210 and anti-centromere antibodies are different risk factors for the progression of primary biliary cirrhosis (PBC). In order to dissect the genetic basis for the production of these autoantibodies, as well as the development and progression of PBC in Japanese patients, we examined single nucleotide polymorphisms (SNPs) in cytotoxic T-lymphocyte(More)
AIM   This study explored recent improvements in the management of hepatocellular carcinoma (HCC) diagnosed during surveillance. METHODS   The subjects were 1074 patients with HCC, subdivided into three groups. Group A comprised 211 patients for whom HCC was detected during periodic follow-up examinations at Kurume University School of Medicine, Group B(More)
To identify the genetic factors involved in the pathogenesis of primary biliary cirrhosis (PBC), we focused on the organic cation transporter 1 (OCT1/SLC22A1), which is closely associated with phosphatidylcholine synthesis in hepatocytes. We selected four (rs683369, rs2282143, rs622342 and rs1443844) OCT-1 single nucleotide polymorphisms (SNPs), and(More)
AIM Insight into hepatic fibrogenesis and carcinogenesis (fibro-carcinogenesis) caused by hepatitis C virus (HCV) infection has come from recent analyses of transforming growth factor (TGF)-β signaling. TGF-β type I receptor and pro-inflammatory cytokine-activated kinases differentially phosphorylate Smad2 and Smad3 to create C-terminally (C), linker (L) or(More)
AIM Various factors are underlying for the onset of non-B, non-C hepatitis virus-related hepatocellular carcinoma (NBNC-HCC). We aimed to investigate the independent risk factors and profiles associated with NBNC-HCC using a data-mining technique. METHODS We conducted a case-control study and enrolled 223 NBNC-HCC patients and 669 controls from a health(More)
Primary biliary cirrhosis (PBC) is an autoimmune liver disease characterized by the presence of autoantibodies to mitochondria (AMA). Recent evidence suggests that PBC develops after a locally driven response in the mucosa, where immunoglobulin A (IgA) is the dominant antibody isotype. In this study, we produced recombinant pyruvate dehydrogenase complex(More)
