Mitochondrial Mutations Make Tumors Spread, Science Now
 









Excerpts: Cancer often strikes its final, fatal blow when a tumor spreads to
other organs. A new study published online today in Science sheds light on this
poorly understood process, called metastasis. The researchers report that
mutations in mitochondrial DNA can spur metastasis and that it can be reversed
with drugs, at least in mice. (...) (...) the fact that antioxidants suppressed
metastasis warrants further study, he says. Kornelia Polyak of the Dana-Farber
Cancer Institute in Boston cautions, however, that clinical trials testing
antioxidants to prevent cancer have yielded mixed results and that giving
antioxidants to someone on chemotherapy could interfere with the treatment.
