How Does Transforming Growth Factor beta Suppress Colorectal Tumor Development?

Researchers review the mechanisms by which loss of transforming growth factor beta (TGFB) proteins contribute to development and progression of colorectal cancer in the January 2017 issue of Gastroenterology. Development and progression of colorectal cancer involve loss of tumor suppressor proteins, including transforming growth factor beta (TGFB) family members. In colon

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

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
