Transcription factor Twist1 is involved in many processes where cells change shape or function. Thereby, Twist1 is crucial for embryonic development, but has also been implicated in cancer progression, researchers say. However, the precise contribution of Twist1 to these processes is under much debate. Scientists describe a new mode of action: a short-term, transient activation of Twist1 primes cells for stem cell-like properties. By contrast, prolonged, chronic Twist1 activity suppresses stem cell-like traits.
