Methylation: Gene Expression at the Right Place and Right Time
Nadia Halim | Dec 5, 1999 | 7 min read
Courtesy of Richard Roberts, New England BiolabsModel methylation reaction: Cytosine nucleotide (red) is flipped out of the DNA double helix by a methyltransferase (white), so it can be methylated. The end product after the methyl group has been transferred to the DNA is pictured in green. A tenuous link between DNA methylation and development has existed for several years. Now findings substantiate the connection. Researchers have found the first human diseases caused by defects in the DNA meth

Next time you buy a designer shirt, be sure to check the label. What you don't see may surprise you. Hidden within the ink or fibers of that shirt could lie an authentication device made not of plastic or metal, but of DNA."DNA has become the gold standard, the highest barrier to product counterfeiting, diversion, and piracy," says Julia Hunter, executive vice president of Applied DNA Sciences in Los Angeles. In this case, though, the term gold is both literal and figurative. The International C

Biofilms are home to millions of microbes, but disrupting their interactions could produce more effective antibiotics.
Detecting Tumors from Shed DNA
Douglas Steinberg | May 13, 2001 | 7 min read
Medical institutions across the United States will begin recruiting volunteers next month for a study that its investigators and outside observers describe as groundbreaking. They say it is the first large-scale trial to test the feasibility of using DNA shed by tumors to find early-stage cancer. During the three-year government-funded project, researchers will analyze DNA from stool samples to detect patterns characteristic of colorectal cancer (CRC). The study will have two other notable fe
An epigenetic inheritance
Tia Ghose | Jan 18, 2009 | 2 min read
It's not just genes that are inherited. Chemical tags that affect gene expression levels may be inherited too, a new study published online this week in Nature Genetics reports. Molecular biologist Arturas Petronis and his colleagues at the Center for Addiction and Mental Health in Toronto, Canada compared DNA methylation patterns from epithelial cells inside the mouths of 39 sets of identical and 40 sets of fraternal twins. Compared to fraternal twins, identical twins had more similar methyla

A few kilograms of DNA could theoretically store all of humanity’s data, but there are practical challenges to overcome.
Luminescence Developments Help Scientists See The Light
James Kling | May 11, 1997 | 9 min read
Biologists are constantly seeking more sensitive assays to detect the presence of organisms or telltale DNA, RNA, and proteins. Although radioactive tags incorporated into the target itself (or into a complementary strand)-and later detected by Geiger counters or film exposures-have traditionally given good sensitivity, the problems of waste disposal and laboratory monitoring have driven a search for alternative tags that have radioactivity's sensitivity but avoid its hazards. Fluorescent tags-
