BEIJING,– A new test that analyzes the tumor at the gene level is 80 percent accurate in predicting which drug or combination of drugs would be most effective against that particular cancer, U.S. researchers reported in the latest eidition of Nature Medicine. A team of researchers from Duke University in North Carolina formulated the test by using an Affymetrix ‘gene chip.’ The tumors of a number of cancer patients were analyzed. The test evolved by studying the activity of genes in the cells of these tumors. The objective was to find a molecule called the ‘Messenger RNA’ in each cell. The trail of ‘Messenger RNA’ gives the genetic signature of the tumor or the activity levels of different genes. From this it […]
