Wired Following Cancer's Red Flags
"Genes are tricksters. They can be turned on or off -- and whether they're on or off decides whether the gene-owner will develop disease.

Gene researchers have embarked on a new field of research, called epigenomics, to determine whether genes are in the on or off position. This type of marker could prove an important diagnostic or therapeutic tool for all types of cancer.

"At Johns Hopkins, researchers are performing clinical trials on about 15 patients with leukemia and other cancers to find out if epigenomics might give pharmaceutical companies a lead for developing cancer drugs.

The research, like all epigenomics research, is studying a chemical found in everyone's DNA called cytosine. Cytosine is the only chemical of the four that make up human DNA (the others are adenine, thymine, and guanine) that is prone to a phenomenon called methylation. When cytosine is methylated, it tuns off its gene. "

"For most of us, formal biology education begins with complex systems--the traditional dissection of a frog in high school biology class is virtually a rite of passage in the U.S.

But the way many people learn about and invest in biotechnology is at the smallest end of the spectrum--the genome, now often described as the "periodic table" of biology. Genomics and all its related buzzwords have been responsible for much of the media attention, government grants, and investment capital heaped on the biotech industry over the past decade.

But just as there is a whole lot of chemistry that happens in between the periodic table and a birthday cake, there is a lot of biology in between the genome and a living organism. With the completion of biology's periodic table within sight, academics and industry players alike are pondering the best way to apply our hard won knowledge.

The only problem is, the path from genome to system seems to get harder the more we learn."

Bioinformatics will be at the core of biology in the 21st century. In fields ranging from structural biology to genomics to biomedical imaging, ready access to data and analytical tools are fundamentally changing the way investigators in the life sciences conduct research and approach problems. Complex, computationally intensive biological problems are now being addressed and promise to significantly advance our understanding of biology and medicine. No biological discipline will be unaffected by these technological breakthroughs.
