How breast cancer cells break free to spread in body
A gene normally involved in the regulation of embryonic development can trigger the transition of cells into more mobile types that can spread without regard for the normal biological controls that restrict metastasis, the new study shows. Analysis of downstream signaling pathways of this gene, called SNAIL, could be used to identify potential targets for scientists who are looking for ways to block or slow metastasis. “This gene relates directly to the mechanism that metastatic cancer cells use to move from one location to another,” said Michelle Dawson, an assistant professor in the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology…
