Dartmouth Medical School researchers have found two proteins that work in concert to ensure proper chromosome segregation during cell division. Their study is in the January 2009 issue of the journal Nature Cell Biology.This finding is relevant for treating solid cancerous tumors that lose the ability to accurately segregate their chromosomes. Tumors that shuffle chromosomes, a process called chromosomal instability, are known to have a poor prognosis."We show that the function of two...

In the 13th January print edition of the journal Current Biology, Instituto Gubenkian de Ciencia researchers provide insight into an old mystery in cell biology, and offer up new clues to understanding cancer. Inês Cunha Ferreira and M³nica Bettencourt Dias, working with researchers at the universities of Cambridge, UK, and Siena, Italy, unravelled the mystery of how cells count the number of centrosomes, the structure that regulates the cell's skeleton, controls the...

U.S. researchers have discovered a cellular process that explains how cruciferous vegetables such as broccoli work to prevent breast cancer. Breast cancer can be protected against by eating cruciferous vegetables such as cabbage and near relatives of cabbage such as broccoli and cauliflower, first author Olga Azarenko of the University of California in Santa Barbara said in a statement. These vegetables contain compounds called isothiocyanates which we believe to be responsible for the...

NERVIANO, Italy, October 23 /PRNewswire/ -- - First Responses in Solid Tumours Reported. Aurora inhibitors play a key role in cell duplication and are implicated in both the onset and progression of numerous types of tumour. A lecture focusing on Aurora kinase inhibitors will be presented today by Dr. Bernard Laffranchi during the 20th EORTC-NCI-AACR Symposium "Molecular Targets and Cancer Therapeutics" organised from 21st to 24th October 2008 in Geneva. Dr Laffranchi, Director Clinical...

U.S. and Israeli medical researchers say they have discovered one of the factors involved in mitosis -- the ability of cells to daily divide and replicate. Since an inability to control mitosis is one of the hallmarks of cancer, the discovery by researchers at the Fox Chase Cancer Center in Philadelphia and the Technion-Israel Institute of Technology in Haifa, Israel, might help increase the efficiency of cancer drugs that disrupt DNA replication, such as gemcitabine, or drugs that prevent...

UA's nanotechnology research group is using proteins from living cells to "grow" wires on microchips. Their work promises to revolutionize the way microchips are made by combining biology and electronics "” leading to smaller, faster and more efficient circuits for cell phones, computers, MP3 players and a thousand other microelectronic devices. But that's only one of the benefits of this research. The work holds promise in several areas, such as improving testing methods for anticancer...

SANTA CRUZ, CA-- Scientists have long known that the social insects in the order Hymenoptera--which includes ants, bees, and wasps--have an unusual mechanism for sex determination: Unfertilized eggs develop into males, while fertilized eggs become females. But the development of an unfertilized egg into an adult (called parthenogenesis) remains a mysterious process. One mystery has been the origin of the centrosome, an essential cellular component that is ordinarily derived from the sperm...

TALLAHASSEE, Fla. - Biologists at Florida State University have uncovered the pivotal role of a gene called "Cut" that acts as a sort of middleman in cell-to-cell communication. A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health...

Cells control mitosis (cell division) by assembling a biochemical switch to block it or by disassembling the switch to trigger it, according to investigators at St. Jude Children's Research Hospital and the Technical University of Munich. The researchers found that when the switch called SCFNIPA is intact, levels of an enzyme called cyclin B1 drop, preventing the enzyme from activating a third protein called Cdk1. By blocking the interaction between cyclin B1 and Cdk1, SCFNIPA prevents the...
