Surprising result suggests that enhancing these mutations´ impact could offer a new way to treat cancer. A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression. But a new study from...

By studying fruit flies, scientists at A*STAR´s Institute of Molecular and Cell Biology (IMCB) have successfully devised a fast and cost-saving way to uncover genetic changes that have a higher potential to cause cancer. With this new approach, researchers will now be able to rapidly distinguish the range of genetic changes that are causally linked to cancer (i.e. “driver” mutations) versus those with limited impact on cancer progression. This research paves the way for...

Research published in the journal Genetics suggests that the genes associated with variation in immune response at a young age are almost completely different from those found in middle age Important insights that explain why our ability to ward off infection declines with age are published in a new research report in the July 2012 issue of the Genetics Society of America's journal, GENETICS (http://www.genetics.org/). A team of U.S. scientists identified genes responsible for this decline...

As the Genetics Society of America's Model Organism to Human Biology (MOHB): Cancer Genetics Meeting in Washington, D.C. drew to a close, it was clear that the mantra for drug discovery to treat cancers in the post-genomic era is pathways. Pathways are ordered series of actions that occur as cells move from one state, through a series of intermediate states, to a final action. Because model organisms — fruit flies, roundworms, yeast, zebrafish and others — are related to...

Loyola researchers are taking advantage of a quirk in the evolution of fruit fly genes to help develop new weapons against cancer. A newly discovered fruit fly gene is a simplified counterpart of two complex human genes that play important roles in the development of cancer and some birth defects. As this fruit fly gene evolved, it split in two. This split has made it easier to study, and the resulting insights could prove useful in developing new cancer drugs. "Evolution has given us a...

The study has demonstrated that genetic variability in the embryo may predispose to cancer in adult life A study recently published in Nature Genetics provides new evidence that the genetic makeup of the embryo may cause the appearance of tumors in adult life. These results bear out the growing theory that some tumors may have an extremely early origin, tracing to the individual's embryonic development, while offering new clues to understand the genetic causes of certain kinds of cancer,...

Researchers at the Hebrew University of Jerusalem and other institutions have identified two distinguishable groups of genes: those that produce very abundant biochemical products in the cell and function properly in the majority of biological processes, and a flexible subset that might have abnormal function in a disease. They demonstrated that these two groups can be found among various organisms and cell types, including stem cells and cancer cells. One set of genes is a robust...

Bacteria evolved way to safeguard crucial genetic material Just as banks store away only the most valuable possessions in the most secure safes, cells prioritize which genes they guard most closely, researchers at the European Molecular Biology Laboratory´s European Bioinformatics Institute (EMBL-EBI) have found. The study, published online today in Nature, shows that bacteria have evolved a mechanism that protects important genes from random mutation, effectively reducing the risk of...

An international team of scientists, led by researchers from the Duke-NUS Graduate Medical School (Duke-NUS) in Singapore and National Cancer Centre of Singapore, has identified hundreds of novel genes that are mutated in stomach cancer, the second-most lethal cancer worldwide. The study, which appears online on April 8, 2012 in Nature Genetics, paves the way for treatments tailored to the genetic make-up of individual stomach tumors. Stomach cancer is the second leading cause of cancer...

Mutations in a gene called XRCC2 cause increased breast cancer risk, according to a study published today in the American Journal of Human Genetics. The study looked at families that have a history of the disease but do not have mutations in the currently known breast cancer susceptibility genes. Sean Tavtigian, Ph.D., a Huntsman Cancer Institute (HCI) investigator and associate professor in the Department of Oncological Sciences at the University of Utah (U of U) is one of three...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
