Description

Quantifying transcriptional bursting from live-cell imaging data is critical for understanding stochastic gene regulation. Here, we present DART (Deep learning for the Analysis and Reconstruction of Transcriptional dynamics) \cite{m}, a deep learning framework that infers promoter-state trajectories from fluorescence intensity traces, enabling the estimation of activation and inactivation rates and the selection of the most appropriate promoter-switching model. Using extensive synthetic datasets spanning a wide range of transcriptional bursting levels, we demonstrate that DART outperforms current binarization methods, including conventional and augmented hidden Markov models, in both accuracy and robustness. Furthermore, a reanalysis of published experimental data using DART reveals a strong linear coupling between activation and inactivation rates, contradicting previous claims of independence. By integrating machine learning with stochastic modelling, DART provides a powerful and generalizable tool for quantitative analysis of transcriptional kinetics from live-cell imaging data.
