A chink in the armor of breast cancer cells: Scientists succeed in killing aggressive form of breast cancer in lab experiments

Working with human breast cancer cells, a team of scientists has successfully turned off a misbehaving protein that fuels the growth of a particularly aggressive, drug-resistant form of the disease known as triple-negative breast cancer. In a set of lab experiments, the team managed to neutralize the protein, called Nodal, a growth factor already known for its role in early embryonic development.
