...form of cancer, but particularly for breast, colon, prostate and even lung. The gains include an explosion of new drugs that are more targeted and less toxic than old-school chemotherapeutic agents. In addition, new tests are beginning to help doctors match drugs more precisely to the genetic and molecular makeup of an individual tumor. Finally, there are remarkable advances in managing the side effects of treatment, which, in the past, could be as debilitating as cancer itself...
...tests that enable doctors to do a better job of matching the treatment to the tumor. Oncotype Dx, introduced in 2004, looks at 21 genes in biopsied tissue to determine whether or not chemotherapy will be helpful for early breast cancer patients with recent diagnoses. At Duke University, molecular geneticist Joseph Nevins is testing a similar gene-based test for lung cancer. Researchers are aiming for tools that will tell them not only whether chemo is needed but also which specific drugs to use. Such a screen already exists for Herceptin, and many others are in development. Meantime...
...team including researchers from Harvard Medical School have discovered a genetic marker for schizophrenia, according to a paper published Tuesday in the journal Molecular Psychology. The data was collected using Whole Genome Association (WGA)—a new technology that allowed the scientists to study all the possible variations of each gene, rather than just one or two at a time. “WGA permits us to examine 500,000 SNPs [genetic variations] across the entire genome in a single test,” said Todd Lencz, the first author of the study. The discovery was a joint...
...terrorism. We want victory.” Meanwhile, HIPJ members handed out anti-war patches and posters. “We want people to wear and post their anti-war voice to show decision-makers our dissent,” said Kaveri Rajaraman, a third-year graduate student of molecular and cellular biology and an HIPJ member. Amar Abbas, a German visitor whose family lives in Iraq, said he appreciated the anti-war protests. “It’s really exciting to see students demonstrating after four years of craziness in Iraq,” he said.
