Washington, DC -- Cancer researchers at Georgetown University Medical Center have taken a step towards understanding how and why a widely used chemotherapy drug works in patients with breast cancer. In laboratory studies, the researchers isolated a protein, caveolin-1, showing that in breast cancer cells this protein can enhance cell death in response to the use of Taxol, one of two taxane chemotherapy drugs used to treat advanced breast and ovarian cancer. But in order to work, they found the protein needs to be “switched on,” or phosphorylated. The results were reported in the current (February 23) issue of the Journal of Biological Chemistry. >>> Discuss This Story
