Signs of aging: Scientists evaluate genes associated with longevity
...related diseases." SAGE involves the isolation of short
gene-specific sequence tags and provides an unbiased and quantitative measurement of gene-expression differences. This study was the first to utilize SAGE to analyze aging-related gene-expression changes. It is expected that the large volume of SAG...

...hemophilic dogs. The viral vector also contained a short
DNA promoter sequence to make the gene active only in liver cells, one of the sites of factor VIII production in non-hemophiliacs. The normal mechanisms of viral reproduction enabled insertion of the genetic material from the engineered vectors int...

Meeting to explore possible gene expression consortium
... microarrays use thousands or tens of thousands of short
lengths of single-strand DNA, fixed in a grid about the size of a postage stamp, to rapidly measure gene activity. It's a powerful technology, but one that has evolved rapidly, and in advance of any underlying scientific infrastructure to quantitativ...

Scientists find microRNAs regulate plant development
...ulatory genes that mediate auxin responses contain short
