BOSTON: In an intriguing approach to the fight against cancer, researchers for the first time have used light to prevent and reverse tumors using a technique called optogenetics to manipulate electrical signaling in cells.
Scientists at Tufts University performed optogenetics experiments on frogs, often used in basic research into cancer because of the biological similarities in their tumors to those in mammals, to test whether this method already used in brain and nervous system research could be applied to cancer.
“We call this whole research program cracking the bioelectric code,” said biologist Michael Levin, who heads the Tufts Center for Regenerative and Developmental Biology.
