Molecule that can switch off cancer discovered | Scientists from the University of Colorado have found a 'switch' that can turn off cancer. They have discovered a molecule
that actually triggers cell death, and they are convinced it can be developed
into a treatment for cancer and other illnesses. They found that the molecule
called caspase, which was already well known for killing cells, could be used
to target specific cancerous ones. According to the researchers, if the finding
can be turned into a treatment it would be a dramatic improvement on chemotherapy,
which kills healthy cells, and well as the cancerous cells to treat the disease.
"Our findings initially seemed too good to be true," Professor Ding Xue, who led
the study, said. "We wound up looking at the results from a number of angles,
including genetics, cell biology and biochemistry. "Eventually we reached the
only logical conclusions we could make. "This is a completely novel finding, and
all of the players in this story are well-known, well studied aspects of a very
important process in our lives. "The minute I saw the results, I knew it was a
very, very important finding with wide implications," he added. The experiments
were conducted on a common, eyelash-sized nematode known as Caenorhabditis elegans, a popular laboratory organism for genetic and biomedical experiments. The study has been published in the 12 March issue of Science. |
