Abstract The rapid development of synthetic biology is a paradigm of how the molecular diversity of naturally occurring gene control components can be used to design synthetic control devices and gene networks that provide precisely programmed transgene expression dynamics in space and time. Here we offer an overview on recent advances in the modular design of trigger-inducible mammalian expression devices that are either responsive by exogenous stimuli such as chemicals and physical cues or controlled by endogenous metabolites driving prosthetic circuits to treat metabolic disorders in a self-sufficient manner. Compatible genetic switches can also be assembled to synthetic gene networks that show highly complex expression dynamics such as temporally resolved band-detect functions or oscillating transgene expression profiles. The ongoing metagenomic discovery and characterization of the unexplored sequence space is constantly increasing the molecular diversity in fundamental control components that fuels the further development of synthetic biology.
