A new study describes a compound that selectively kills cancer cells by restoring the structure and function of one of the most commonly mutated proteins in human cancer, the "tumor suppressor" p53. The research, published by Cell Press in the May 15th issue of the journal Cancer Cell, uses a novel, computer based strategy to identify potential anti-cancer drugs, including one that targets the third most common p53 mutation in human cancer, p53-R175H. The number of new cancer patients...

Researchers trace influence via mouse model that allows oncogene to be turned on and off A genetic mutation that drives the initiation of pancreatic cancer also manipulates metabolic pathways to support tumor growth and progression, scientists report in the journal Cell. This newly discovered role for the Kras oncogene opens up a new category of potential targets for thwarting the influential mutation, which has proved difficult to attack directly, said study co-lead author Haoqiang...

St. Jude Children's Research Hospital scientists discovered that the protein TopBP1 is indispensable for preventing the accumulation of DNA damage early in brain formation and might also serve as a tumor suppressor St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer. Researchers showed that cells in the...

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis. Researchers at the University of Helsinki discovered that spontaneous induction of KSHV lytic replication in tumors drastically attenuated the p53-dependent apoptotic response not only to a targeted therapy (Nutlin-3) but also to genotoxic...

Team discovers mechanism for destroying particular cancer cells An international team of scientists has announced a new advance in the ability to target and destroy certain cancer cells. A group led by the University of Leicester has shown that particular cancer cells are especially sensitive to a protein called p21. This protein usually forces normal and cancer cells to stop dividing but it was recently shown that in some cases it can also kill cancer cells. However, scientists have...


Word of the Day
