                Abstract – Gene transcription regulation is a noisy process that can lead to regime shifts and
these shifts are difficult to predict. In this Letter, we consider spatiotemporal fluctuations in gene
transcription regulation, and employ a spatially extended gene transcription regulation system by
using theoretical analysis and numerical simulation. We find that the system produces a regime
shift from a low (high) to a high (low) protein concentration state (i.e., the transform of the switch
of gene transcription regulation), and we apply spatial early warning signals (e.g., rising spatial
variance, spatial skewness, spatial kurtosis, and lag-1 autocorrelation) to study the regime shifts
of protein concentration. The results show that the spatial early warning signals can be used as
a robust indicator of predicting gene transcription regulation switch. Once the signal is detected,
we will take measures to intervene. Our results may have a positive effect on improving early
treatment interventions for complex human diseases.
