Learning the language of DNA

... "This knowledge will be a major resource to the biomedical research community." Part of understanding the language of cells lies in identifying promoters - the DNA regions at the start of genes that regulate their activity. "We have identified the core promoters of the large majority of genes in the mous...

Interfering RNA silences genes in 'slippery' immune cells

...tion of hostile viruses. Over the past few years, biomedical researchers have been investigating how they might eventually harness RNAi in new medicines. Another line of research uses RNAi as a research tool, investigating the functions of specific genes by studying what happens when RNAi temporarily silences ...

RNA interference stops colon cancer spread in mice

Using one of the newest and most powerful tools of biomedical science, University of Texas Medical Branch at Galveston (UTMB) researchers have scored a dramatic success in the battle against colorectal cancer. The scientists were the first to use what are known as "small interfering RNAs" to block the spread o...

New MRI technique quickly builds 3-D images of knees
