RNA snippet suppresses spread of aggressive breast cancer

CAMBRIDGE, Mass. (June 11, 2009) A low cellular level of a tiny fragment of RNA appears to increase the spread of breast cancer in mouse models of the disease, according to researchers at Whitehead Institute for Biomedical Research. Measuring levels of this so-called microRNA, which is also a...

Stanford researchers unmask proteins in telomerase, a substance that enables cancer

...hen sent those pieces through a sensitive device that detected the pieces and compared the protein sequence to a genetic database that could match the snippet to a particular gene. With the gene in hand, the researchers could find the protein made by that gene. They also used genetic trickery to disable o...

...the blood in order to fully develop. In their research, published in the May 23rd issue of the journal Nature, Jacobs-Lorena and his team identified a snippet of protein called SM1 that attaches itself to the gut wall of the mosquito, essentially blocking the parasite. The gene's activity is triggered w...

Researchers find snippet of RNA that helps make individuals remarkably alike

"No two people are alike." Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are. Uniformity, or singleness of form, is not unique to humans but a general property of life. Biologists have lon...

Boston University biomedical engineers teach bacteria to count

... snips its own gene out of the network, flips it over and sticks it back in. Once the gene is backwards, it can no longer be transcribed but an extra snippet of DNA the researchers attached to its tail acts as a bookmark, showing protein-making machinery where to resume work. Each successive flip-over count...

RNA interference therapy heals growth deficiency disorder in a live animal

... When the gene that produces the defective human growth hormone is inserted into the mouses genome, it also stunts the mouses growth. But when a small snippet of RNA that interferes with the hormones production is also added, the mouse is restored to normal. It has been very satisfying to figure out the und...
