A Forward Genetic Screen Identifies Suppressors of Hepatocellular Carcinogenesis

Using 2 powerful high-throughput in vivo screening tools, researchers identified and validated 27 genes as suppressors of hepatocellular carcinoma (HCC), reported in the August issue of Gastroenterology. Their findings support the role of Ras signaling in development of HCC and provide new therapeutic targets. Sorafenib is the only treatment for patients

Author Q&A Series: H pylori-associated Gastric Cancer

Gastric tumors and tissues from humans and mice accumulate somatic mutations in various genes in the gastric mucosa upon Helicobacter pylori infection, researchers report in the August issue of Gastroenterology. In the study, Takahiro Shimizu et al. show that increased cytidine deaminase activity in these tissues promotes the accumulation of these mutations and might

What is Intrahepatic Cholangiocarcinoma?

Researchers have found that intrahepatic cholangiocarcinomas (ICCs) are really 2 different groups of tumors, based on molecular and genetic analyses, reported in the April issue of Gastroenterology. These findings identify class-specific mechanisms of oncogenesis that could lead to new treatment approaches for this common liver cancer. Cholangiocarcinoma is the second most
