Designer cells: artificial enzyme can activate a gene switch

Complex reaction cascades can be triggered in artificial molecular systems: Swiss scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene switch that triggers the creation of a fluorescent protein. The findings were reported by researchers from the NCCR Molecular Systems Engineering, led by the University of Basel and ETH Zurich.
