Finding a likely target, of course, doesn't guarantee success. Consider colon cancer: scientists believe at least three things have to go wrong for colon cancers to form. They liken the situation to a car accident. One of the genes that tells cells to divide (the accelerator) must get stuck...
But even among the rarefied biotech elite, there are mavericks who think they have a better idea. They want to move one step closer to the gene by targeting the RNA molecules that transfer information from genes to proteins. And they have the perfect molecular tool with which to do...
Genes don't just tell you how to make drugs. They can also tell you whom to treat.
So how would you make a gene chip? Let's say you want to identify which genes get turned on, or "expressed," by the immune system in the first few weeks after the AIDS virus begins its attack on the body. First you download the sequences of perhaps 10,000...
Once the strands are complete, the gene chip is ready for use. You take a sample of blood from a patient who has just developed a raging HIV infection. Various genes in his immune system are churning out millions of RNA molecules that will assemble the proteins needed to combat...
