A new study shows how SRC, a nonmembrane tyrosine kinase, is a common signaling node in trastuzumab resistance caused by different mechanisms in HER2-positive breast cancers (pages 461–469). A SRC inhibitor restored trastuzumab sensitivity in vitro and in mouse tumor models, suggesting a new way to tackle drug resistance in breast tumors.
