AIM To summarize the annual nationwide survey on fulminant hepatitis (FH) and late-onset hepatic failure (LOHF) between 2004 and 2009 in Japan. METHODS The annual survey was performed in a two-step questionnaire process to detail the clinical profile and prognosis of patients in special hospitals. RESULTS Four hundred and sixty (n = 227 acute type; n =(More)
Hepatocyte nuclear factor 4alpha (HNF-4alpha) is a transcription factor that controls embryonal liver development and that maintains and regulates gene expression in adult liver cells. We have previously demonstrated that transient overexpression of HNF-4alpha up-regulates a number of liver-specific genes in hepatoma cell lines. In this study, we extend(More)
Human hepatocytes usually are resistant to TNF-alpha cytotoxicity. In mouse or rat hepatocytes, repression of NF-kappaB activation is sufficient to induce TNF-alpha-mediated apoptosis. However, in both Huh-7 human hepatoma cells and Hc human normal hepatocytes, when infected with an adenovirus expressing a mutated form of IkappaBalpha (Ad5IkappaB), which(More)
Hepatocyte nuclear factor 4alpha (HNF-4alpha), a liver-specific transcription factor, plays a significant role in many liver-specific functions, including lipid, glucose, drug, and ammonia metabolism, and also in embryonal liver development. However, its functions and regulation are not yet clearly understood. In this study, we constructed an adenovirus(More)
The diagnostic criteria of fulminant hepatitis in Japan are different from those of acute liver failure in Europe and the United States, both in regard to the histological features in the liver and the cutoff values of the prothrombin time. Thus, the Intractable Hepato-Biliary Disease Study Group established novel diagnostic criteria for "acute liver(More)
To describe a case of autosomal-dominant (AD)-chronic mucocutaneous candidiasis (CMC) with a signal transducer and activator of transcription (STAT) 1 gene mutation, and some of the important complications of this disease such as chronic hepatitis. We present a 23-year-old woman with CMC, chronic active hepatitis, and hypothyroidism. Her father also had(More)
Fulminant hepatic failure (FHF) is still associated with high mortality despite recent advances in medical management. There is need of an effective and safe bioartificial liver (BAL) support to help keep patients with FHF alive until an organ becomes available for transplantation or the native liver recovers. The aim of this study was to establish highly(More)
BACKGROUND/AIMS The extracellular matrix plays an essential role in the regulation of cell proliferation in different cell types. However, the regulation of cell cycle control in hepatocytes in response to growth factors and extracellular matrix signals is not well understood. The aims of this study were to investigate the expression of key cell cycle(More)
Serum pro- and anti-inflammatory mediators in patients with acute liver diseases were assessed to clarify the clinical significance of these measurements in relation to disease severity. Concentrations of circulating tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, IL-10, IL-12, and soluble TNF receptors (sTNFR) p55 and p75 were measured at(More)
AIM   In Japan, the indication for liver transplantation in patients with acute liver failure (ALF) is currently determined according to the guideline published in 1996. However, its predictive accuracy has fallen in recent patients. Thus, we attempted to establish a new guideline. METHODS   The subjects were 1096 ALF patients enrolled in a nationwide(More)
