Here, the authors show that signal transducer and activator of transcription 3 (STAT3) has dual functions in small cell lung cancer as its deletion inhibited primary tumor growth but boosted metastatic spread. These seemingly opposing functions are a result of the requirement of STAT3 for stimulator of interferon genes–interferon signaling in metastasis and the authors show how it can be targeted in mice.
