Latest Regulation of gene expression Stories
In the quest for new approaches to treating and preventing disease, one appealing route involves turning genes on or off at will, directly intervening in ailments such as cancer and diabetes, which result when genes fail to turn on and off as they should.
Even microbes are governed by the principle of supply and demand â€“ at least at the genetic level.
Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities, according to two studies published May 15.
Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine â€“ the A,T,G and C that make up the DNA code. But those are not the whole story.
Milestone Achieved A Year Ahead of Schedule ST. LOUIS and RICHMOND, Calif., Jan. 12 /PRNewswire-FirstCall/ -- Sangamo BioSciences, Inc.
A research team at the Stowers Institute has discovered how the expression of one of the Hox master control genes is regulated in a specific segment of the developing brain.
Canadian and Hungarian scientists say they've discovered DNA from suicide victims who suffered major depression shows an important chemical modification. Dr.
By Ponomarev, Vladimir Recent years have witnessed a remarkable increase in our knowledge and understanding of the genetics and molecular biology of human diseases. During the past 2 decades, technologic innovations revolutionized molecular and cell biology.
Neurobiologists have discovered a mechanism by which the constantly changing brain retains memoriesâ€”from that dog bite to that first kiss. They have found that the brain co-opts the same machinery by which cells stably alter their genes to specialize during embryonic development.
At any given time, most of the roughly 30,000 genes that constitute the human genome are inactive, or repressed, closed to the cellular machinery that transcribes genes into the proteins of the body. In an average cell, only about one in ten genes is active, or expressed, at any given moment, with its DNA open to the cell' transcriptional machinery.
