Seeking social genes

In order understand the evolution of complex societies, researchers are sequencing the genomes of social insects. The most recent data, published this week in the Early Edition of Proceedings of the National Academy of Sciences, come from several sp...

Finger-trap tension stabilizes cells’ chromosome-separating machinery

Scientists have discovered an amazingly simple way that cells stabilize their machinery for forcing apart chromosomes. Their findings are reported Nov. 25 in Nature. When a cell gets ready to split into new cells, this stable set-up permits ...

The most aggressive forms of breast cancer elude cellular control mechanisms...

About 30% of breast cancer patients have tumours that show rapid growth and invasion through the body. A common denominator in all of these cases is the presence of a large number of Her2 proteins in tumour cellular membranes. Consequently, these ag...

Trigger mechanism provides ‘quality control’ in cell division

SALT LAKE CITY, November 22, 2010 -- Researchers from Huntsman Cancer Institute (HCI) at the University of Utah report that they have identified a previously undiscovered trigger mechanism for a quality control checkpoint at the very end of the cel...

Scientists announce new advance with potential for future cancer targeting

New research that provides potential for exciting new approaches to targeting diseases such as cancer has been announced by an international team of academics. They have also announced the potential for more targeted treatments following their ide...

Johns Hopkins researchers reshape basic understanding of cell division

By tracking the flow of information in a cell preparing to split, Johns Hopkins scientists have identified a protein mechanism that coordinates and regulates the dynamics of shape change necessary for division of a single cell into two daughter cell...

At the crossroads of chromosomes

PHILADELPHIA -- On average, one hundred billion cells in the human body divide over the course of a day. Most of the time the body gets it right but sometimes, problems in cell replication can lead to abnormalities in chromosomes resulting in m...
