Many cellular events are thought to be controlled by the temporal upregulation of multiple RNAs; the timing of the upregulation of these RNAs is not always the same. In this study, we first show that our light-directed intracellular RNA delivery method induced high concentrations of RNA in a short period. This effect was beneficial for the temporal control of cellular events by functional RNAs. Next, we stimulated the short-term upregulation of two different RNAs at different time points. Cytosolic delivery of a first RNA was induced by red light; thereafter, cytosolic delivery of a second RNA was induced by near-infrared light. The time difference between the introduction of the first and second RNA can be short (0.5-4 h) or long (>8 h). This strategy shows the potential for future applications of the deliberate control of time-dependent RNA concentration to guide various cellular functions by multiple RNAs.
