ABSTRACT
"This finding highlights the convergence of tumorigenic and embryonic signaling pathways. From a translational perspective, Nodal signaling provides a novel target for treatment of aggressive cancers such as melanomas," said Mary J. C. Hendrix, the corresponding author, of Children's Memorial Research Center where the discovery was made."
