A central clock runs the cell division cycle

A central clock runs the cell division cycleScientists have long known that proteins called cyclins regulate cell division in yeast, but this picture has lately come into question as oscillations in gene expression were posited to run independently in the cell division cycle. Now a new study confirms that cyclins are indeed in control. More »

Researchers discover new aspect of gene regulation and a possible target for cancer drugs

Researchers discover new aspect of gene regulation and a possible target for future cancer drugsThe expression of about three-quarters of a cell’s active genes is controlled by a process in which the DNA-transcribing enzyme hesitates before going to work. Experiments have identified the complex of proteins that helps restart this enzyme when it stalls, and so helped to explain how some promising cancer drugs work. More »
