A team of researchers led by the University of Leicester has shed new light on how the regulation machinery that controls gene expression works by characterising a complex known as the NuRD complex.

What if we could program living cells to do what we would like them to do in the body? Having such control—a major goal of synthetic biology—could allow for the development of cell-based therapies that might one day replace ...

All the tissues in the human body are made from proteins, and for every protein, there's a stretch of DNA in the human genome that "codes" for it, or describes the sequence of amino acids that will produce it.

Frog embryos do not fully control which genes they can turn on or off in the beginning of their development – but their mother does, through specific proteins in the egg cell. Molecular developmental biologists at Radboud ...

There are about 20,000 genes in the human genome, but not all are used in all cells at all times. At any given moment, a cell is converting only roughly half its genes into proteins. And of those active genes, about 75 percent ...

Cells dynamically respond to environmental signals by turning appropriate sets of genes on or off. The "control system" that determines which genes need to be expressed at what time depends primarily on the interactions between ...
