Bioinformatic Search Identifies Tapeworm Drug for Treatment of Hepatocellular Carcinoma

In a bioinformatic search for agents that alter the hepatocellular carcinoma (HCC)-specific gene expression pattern, researchers identified the anthelmintic drug niclosamide as a potential anti-tumor agent, described in the June issue of Gastroenterology. Niclosamide and its ethanolamine salt (NEN), with greater bioavailability, slowed growth of genetically induced liver tumors and

What are the Different Types of Liver Cancer, and How do They Develop?

A review article in the March issue of Gastroenterology discusses different hypotheses about the cells responsible for liver tumorigenesis. The article also reviews the different classes of liver tumors, based on the molecular features, and how these affect patient prognosis. Daniela Sia et al describe the distinct molecular and clinical features of hepatocellular

How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

Researchers have developed a patient-derived cell line-based model to study how intratumor heterogeneity affects sensitivity of hepatocellular carcinoma (HCC) to different therapeutic agents, reported in the January issue of Gastroenterology. HCCs have a large amount of genetic heterogeneity within each tumor, making them difficult to treat. Multiple regions of tumors

  • A Forward Genetic Screen Identifies Suppressors of Hepatocellular Carcinogenesis

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

  • Genetic Analysis of Tumors Could Improve With Proper Controls

Genetic Analysis of Tumors Could Improve With Proper Controls

Up to two thirds of mutations identified in tumors also exist in matched, non-tumor tissues, researchers have found. It is therefore important for oncologists to identify the mutations that actually promote the progression of a patient’s tumor before selecting therapy. The finding, published in Science Translational Medicine on 15 April, comes

  • How Does Smoking Lead to Pancreatic Cancer?

How Does Smoking Lead to Pancreatic Cancer?

Nicotine promotes pancreatic carcinogenesis by disrupting signaling and transcriptional pathways to cause dedifferentiation of acinar cells, researchers report in the November issue of Gastroenterology. One fourth of all deaths from pancreatic ductal adenocarcinoma (PDAC) are associated with tobacco use, and heavy smoking increases risk for PDAC 6-fold. Although smokers develop PDAC

Stem Cells Account for Different Fates of Adenomatous and Hyperplastic Polyps

Adenomatous polyps expand the pool of colon stem cells to become malignant, whereas hyperplastic polyps (HPPs) do not, and therefore remain benign, according to a study published in the September issue of Gastroenterology. Many colorectal cancers arise from adenomatous polyps, which contain mutations that inactivate the tumor suppressor APC. These
