Cellular Receptors Used To Track Prostate Cancer
December 13, 2007 at 6:14 PM
Cancer News
A report on the work by BCM researchers with fibroblast growth factor receptor 1 appears today in the journal Cancer Cell.
Since we are manipulating the target gene itself, we can ask, what will happen" If we turn it off, what happens" That recapitulates the effect of a specific drug, said Dr. David Spencer, professor of immunology at BCM. By turning the gene on and off at various time points, we can define a susceptibility window for that drug, a time in the progression of the disease when the gene would be an appropriate target.
That therapeutic window defines the time when shutting off the gene would also shut down progression of the cancer. Previous studies show that fibroblast growth factor receptor 1 may have a role in initiating prostate cancer, he said. As a result, some companies have developed drugs designed to block the receptor. Spencers work looks at what would happen if the receptor is blocked.
In his mouse, he used a synthetic drug that turned the re-engineered fibroblast growth factor receptor on. As the gene product was activated, the prostate gland began dramatic, synchronized changes characteristic of cancer. However, when he withdrew the drug that turned the receptor on, the changes reversed over several weeks until the prostate gland appeared normal.
