Squamous Cell Carcinoma Antigen-1 (SCCA1) overexpression has been observed in tumours of epithelial origin and in hepatocellular carcinoma. Previous data indicate that this serpin inhibits apoptosis, while its proliferative activity was only recently proposed. The aim of this study was to evaluate the effect of SCCA1 on liver cells in a transgenic mouse(More)
UNLABELLED The diagnosis of hepatic encephalopathy (HE) relies on clinical, neurophysiological, psychometric and laboratory variables. The relationships between such tests remain debated. The aim of this study was to determine the laboratory correlates/prognostic value of neurophysiological/psychometric abnormalities in patients with cirrhosis. Seventy-two(More)
Hepatitis B virus (HBV) and hepatitis C virus (HCV) coinfection is often associated with severe forms of liver disease. However, comprehensive studies are lacking, and scant information is available regarding the virological behavior over time in coinfected patients. This study enrolled 133 untreated HBV/HCV-positive patients (male/female = 102/31; median(More)
BACKGROUND In the sera of liver, colorectal and prostate cancer patients, several biomarkers may be detected as IgM immune complexes. To determine whether the presence of immune complexes was correlated to an increase of IgMs, we measured the IgM content in the sera of patients with hepatocellular carcinoma (HCC) and cirrhosis, and evaluated the occurrence(More)
About 3-4% of cirrhotic patients develop primary liver cancer every year. Specific serologic markers have not yet been identified for screening of high risk patients. The serpin squamous cell carcinoma antigen (SCCA) is overexpressed in liver cancer and circulating SCCA-IgM complexes have been described in patients with hepatocellular carcinoma (HCC). The(More)
About 30% of the patients with chronic hepatitis develop a progressive liver disease and one of the most intriguing issues is the detection of noninvasive markers for fibrosis stage and disease progression. High levels of squamous cell carcinoma antigen (SCCA)-immunoglobulin M (IgM) are detectable in hepatocellular carcinoma and their increase in cirrhotic(More)
We assessed the presence of alpha-fetoprotein (AFP) complexed with IgM (AFP-IgM IC) in serum of patients affected by hepatocellular carcinoma (HCC), cirrhosis and chronic hepatitis as well as in healthy subjects by means of a dedicated ELISA assay. The amount of AFP-IgM IC was expressed in arbitrary units (AU) on a reference standard curve. Free AFP (FAFP)(More)
IgM antibodies bound to different cancer antigens have shown recently a higher diagnostic value, compared with the corresponding free molecule, giving rise to a new family of biomarkers. High or increasing levels of Squamous Cell Carcinoma Antigen (SCCA)-IgM immune complexes were associated with more advanced liver disease and increased risk of development(More)
Transforming growth factor-beta1 (TGF-beta1) is the master cytokine in the pathogenesis of liver fibrosis. TGF-beta1 and extent of fibrosis were correlated recently to the serpin SERPINB3 in idiopathic pulmonary fibrosis, a chronic disease recalling liver cirrhosis. The aim of this study was to assess the relation between SERPINB3, TGF-beta1 and fibrosis in(More)
A variant of the serpin squamous cell carcinoma antigen (SCCA) has been identified as a hepatitis B virus binding protein and high expression of SCCA has recently been found in hepatocarcinoma. Since HBV is involved in liver carcinogenesis, experiments were carried out to examine the effect of HBV preS1 envelope protein on SCCA expression. Surface and(More)
