Latest Oncogene Stories
Jean-Christophe Marine (VIB, K.U.Leuven) strongly argues against the use of Cop1-inhibitory drugs. The protein Cop1 has "“for a long time - been seen as an attractive drug target for cancer. But Jean-Christophe Marine found out that Cop1 acts as a tumor suppressor, and thus inhibits tumor formation. His new data will have direct implications for the development of cancer drug targets.Tumorigenesis: loss of controlTumors form when control over the cell division is lost; a process that could...
Scientists at the University of East Anglia (UEA) have discovered a rogue gene which "“ if blocked by the right drugs "“ could stop cancer in its tracks.Published today by the journal Oncogene, the discovery is a breakthrough in our understanding of how cancer spreads. It is hoped the research will lead to new drugs that halt the critical late stage of the disease when cancer cells spread to other parts of the body.The culprit gene "“ known as WWP2 - is an enzymic bonding agent found...
C. elegans model shows how RAS oncogene switching determines a cell's fateThe National Cancer Institute estimates that more than 43,000 Americans were diagnosed with pancreatic cancer last year and more than 36,000 died from the disease. Despite advances in genetic science showing that the Ras oncogene is mutated in virtually all pancreatic cancers, scientists have been frustrated by the complexity of the signaling pathways in humans, which make it difficult to pinpoint potential therapeutic...
Lost microRNAs put brakes on tumorsBy determining what goes missing in human cells when the gene that is most commonly mutated in pancreatic cancer gets turned on, Johns Hopkins scientists have discovered a potential strategy for therapy.The production of a particular cluster of genetic snippets known as microRNAs is dramatically reduced in human pancreatic tumor cells compared to healthy tissue, the researchers report in a study published Dec. 15 in Genes and Development. When the team...
An international, multi-center study has revealed the discovery of a novel oncogene that is associated with uveal melanoma, the most common form of eye cancer. Researchers have isolated an oncogene called GNA11 and have found that it is present in more than 40 percent of tumor samples taken from patients with uveal melanoma. The findings are being published early online November 17, 2010 in the New England Journal of Medicine and will appear in the December 2, 2010, print issue."These...
Paving way for new therapeutic investigationResearchers at the Hebrew University of Jerusalem have discovered that Vav1 "“ an oncogene (cancer-causing gene) found in recent years to be one of the factors in tumorous tissue growth -- plays a wider role in several types of cancer than had previously been thought. The discovery has implications for further concentration on targeting this gene in cancer research.The work of the researchers, led by Dr. Shulamit Katzav-Shapira of the Institute...
The immune system may play a critical role in ensuring the success of certain types of cancer therapies, according to a new study by researchers at the Stanford University School of Medicine. The research showed treatments that disable cancer-promoting genes called oncogenes are much more successful in eradicating tumors in the presence of a signaling molecule secreted by kind of immune cell called a T helper cell.The finding is important because many drugs now in use in humans are often...
New hypothesis in the FASEB Journal suggests balance between NF-kB and p53 signaling is a promising target for new drugsA new report published in the October 2010 print issue of The FASEB Journal (http://www.fasebj.org) offers a ray of hope in the search for new cancer drugs. By examining the seemingly conflicting roles of how oncogenes and tumor suppressor genes handle cellular stress, scientists from the Institute for Advanced Studies in New Jersey argue that each of these opposing systems...
Researchers at UCLA's Jonsson Comprehensive Cancer Center have discovered a new cell signaling pathway that controls cell growth and development, a pathway that, when defective, helps promote the formation of several major forms of human cancer, including lymphoma and leukemia.The new pathway, part of a global DNA damage response, turns off 136 genes, including some that have are known to cause cancer because, unchecked, they can promote aberrant cell division."It's important to make...
RNAi screening used for the first time to study Ewing's sarcomaThe first study of Ewing's sarcoma that screened hundreds of genes based on how they affect cell growth has identified two potential anti-cancer drug targets, according to a scientific paper by the Translational Genomics Research Institute (TGen) published this month in the journal Molecular Cancer.Ewing's sarcomas are rare, but aggressive cancer lesions that occur most frequently in the bones of teenagers. They represent nearly 3...
