FISH and Mutations Best Identify Biliary Stricture Malignancies

Addition of fluorescence in situ hybridization (FISH) and mutation analyses to cytology analysis significantly increases the sensitivity of detection of malignancies in biliary strictures, researchers report in the June issue of Clinical Gastroenterology and Hepatology. These techniques can be performed using standard brush samples collected during endoscopic retrograde cholangiopancreatography, with mutations detected in

How Do NS5A Inhibitors Prevent HCV Replication?

Researchers have uncovered the mechanisms of drugs that inhibit the hepatitis C virus (HCV) non-structural protein 5A (NS5A), described in the August issue of Gastroenterology. In a quantitative analysis of the kinetics of NS5A inhibitors, David R. McGivern et al.  show that these agents rapidly inhibit intracellular assembly of virions and

Researchers Characterize 4 Molecular Subtypes of Gastric Cancer

Stomach cancers fall into 4 distinct molecular subtypes, researchers report. This information could lead to new strategies to treat patients with specific types of gastric cancer. In the study, published online July 23, 2014, in Nature, researchers with The Cancer Genome Atlas Network (TCGA) report findings that could change how
