A fine kinetic balance of interactions directs transcription factor hubs to genes [RNA-Seq]

Project description:Eukaryotic gene regulation relies on the binding of sequence-specific transcription factors (TFs). TFs bind chromatin transiently yet occupy their target sites by forming high-local concentration microenvironments (hubs and condensates) that increase the frequency of binding events. Despite their ubiquity, such microenvironments have been difficult to study in endogenous contexts due to technical limitations. Here, we overcome these limitations and investigate how hubs drive TF occupancy at their targets. Using a DNA binding perturbation to a hub-forming TF, Zelda, in Drosophila embryos, we find that hub properties, including the stability and frequencies of associations to targets, are key determinants of TF occupancy. Our data suggest that hub targeting is driven not just by specific DNA motif recognition, but also by a fine-tuned kinetic balance of interactions between TFs and their co-binding partners.

Fine kinetic transcriptome analysis during jasmonate signaling

Project description:To study the role of the plant hormone jasmonate in regulating stress-induced allocation of photosynthetic products between growth- and defense-related processes, we used RNA-sequencing to query the Arabidopsis transcriptome at high temporal resolution over 24 h after treatment with the bacterial toxin coronatine (COR, 5 micromolar), a high-affinity agonist of the JA receptor, or with a mock solution to account for diurnal changes in gene expression. These data establish a fine-scale view of the kinetics of jasmonate signaling, as well as of the diurnal patterns of gene expression.

Single-cell Total-RNA Profiling Unveils Regulatory Hubs of Transcription Factors

Project description:Recent development of RNA velocity uses master equations to establish the kinetics of the life cycle of RNAs from unspliced RNA to spliced RNA (i.e., mature RNA) to degradation. To feed this kinetic analysis, simultaneous measurement of unspliced RNA and spliced RNA in single cells is greatly desired. However, the majority of single-cell RNA-seq chemistry only captures mature RNA species to measure gene expressions. Here, we develop a one-step total-RNA chemistry-based scRNA-seq method: snapTotal-seq. We benchmarked this method with multiple single-cell RNA-seq assays in their performance in kinetic analysis of cell cycle by RNA velocity. Next, with LASSO regression between transcription factors, we identified the critical regulatory hubs mediating the cell cycle dynamics. We also applied snapTotal-seq to profile the oncogene-induced senescence and identified the key regulatory hubs governing the entry of senescence. Furthermore, from the comparative analysis of unspliced RNA and spliced RNA, we identified a significant portion of genes whose expression changes occurred in spliced RNA but not to the same degree in unspliced RNA, indicating these gene expression changes are mainly controlled by post-transcriptional regulation. Overall, we demonstrate that snapTotal-seq can provide enriched information about gene regulation, especially during the transition between cell states.
