Beclin 1 mRNA strongly correlates with Bcl-XLmRNA expression in human hepatocellular carcinoma.

Beclin 1 physically associates with Bcl-x(L) and is considered as a haploinsufficient tumor suppressor. As the role of Beclin 1 in hepatocellular carcinoma (HCC) is unknown, we determined Beclin 1 mRNA expression in 27 pairs of tumoral/nontumoral (T/NT) liver samples. The Beclin 1 mRNA T/NT ratio was less than 0.

Comparison of test performance profile for blood tests of liver fibrosis in chronic hepatitis C.

Background/aims: We evaluated the test performance profile (TPP) of blood tests of liver fibrosis.

Methods: Three hundred and fifty-six patients with C chronic hepatitis were included in two centers. Metavir staging of liver specimens by two independent pathologists and the following tests were evaluated: Fibrotest (FT), APRI, FibroMeter (FM), and Hepascore (HS).

Validation and comparison of indexes for fibrosis and cirrhosis prediction in chronic hepatitis C patients: proposal for a pragmatic approach classification without liver biopsies.

Noninvasive indexes have been developed to predict fibrosis staging. The aim of this study was to assess the diagnostic accuracy of these indexes in comparison with liver histology in hepatitis C virus (HCV)-infected patients. A total of 235 consecutive patients with HCV infection from the Fibropaca multicentre independent study were included in this paper.

Human pancreatic mucinous cystadenoma is characterized by distinct mucin, cytokeratin and CD10 expression compared with intraductal papillary-mucinous adenoma.

Aims: To examine cytokeratin, epithelial glycoprotein (mucin) and glycoprotein CD10 expression in benign mucinous cystdenomas (MCAs) in comparison with intraductal papillary mucinous adenomas (IPMAs).

Methods And Results: Thirty MCAs of the pancreas were analysed for immunohistochemical expression of cytokeratin (CK) 7, CK20, MUC1, MUC2, MUC5AC and CD10 and were compared with 16 IPMAs. CK7 was expressed in all neoplasms.

Independent prospective multicenter validation of biochemical markers (fibrotest-actitest) for the prediction of liver fibrosis and activity in patients with chronic hepatitis C: the fibropaca study.

Objectives: Fibrotest (FT) and Actitest (AT) are biochemical markers of fibrosis and activity for use as a non-invasive alternative to liver biopsy in patients with chronic hepatitis C virus (HCV). The aim of this study was to perform an external validation of FT and AT and to study the discordances between FT/AT and liver biopsy in patients with chronic hepatitis C.

Methods: A total of 519 consecutive patients with chronic HCV were prospectively included in five centers, with liver biopsy and biochemical markers taken at the same day.
