Latest Regulation of gene expression Stories
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.
Writing in the February 17, 2012 issue of the journal Cell, researchers at the Ludwig Institute for Cancer Research, the University of California, San Diego School of Medicine and the Toronto Western Research Institute peel away some of the enduring mystery of how zygotes or fertilized eggs determine which copies of parental genes will be used or ignored.
Personal change can redefine or even save your life—especially if you are one of a hundred yeast cell clones clinging to the skin of a grape that falls from a sun-drenched vine into a stagnant puddle below.
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
