Latest Regulation of gene expression Stories
Methylation refers to a chemical modification of DNA and this modification can occur in millions of positions in the DNA sequence.
Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells.
Scientists recently completed a study that shows the possibility that stem cells work towards maturity at an earlier stage than originally thought.
Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes—and revealing new clues as to what happens when this process goes awry.
Two opposing teams battle it out to regulate gene expression on the DNA playing field. One, the activators, keeps DNA open to enzymes that transcribe DNA into RNA.
Salk study finds stress triggers widespread epigenetic changes that aid in disease resistance
For about a dozen years, synthetic biologists have been working on designing genetic circuits to perform novel functions such as manufacturing new drugs, producing fuel or even programming the suicide of cancer cells.
Molecular geneticists call big boss proteins that switch on broad developmental or metabolic programs "master regulators," as in master regulators of muscle development or fat metabolism.
What happens to a stem cell at the molecular level that causes it to become one type of cell rather than another?
Anyone who's tried a weekend home improvement project knows that to do a job right, you've got to have the right tools.
