Project: Mechanisms for Establishment of Transcriptional Memory,
NCN SONATA, UMO-2022/47/D/NZ1/01883

About the project:

This project aims to discover novel epigenetic mechanisms by understanding cellular, molecular and structural aspects of initiation of interferon-gamma (IFNγ) transcriptional memory.

Epigenetics is a process that describes a heritable phenotype resulting from changes in the cell without alterations in the DNA sequence. It is fundamental for multicellular life as it maintains gene expression during growth and in adulthood.

Transcription factor feedback loops can sustain active gene expression but are not always required. This suggests that other processes are involved in preserving active transcription. Strikingly, such mechanisms are largely unknown. This knowledge gap comes from the fact that uncoupling transcription from maintenance of active states is difficult to achieve experimentally. Due to this reason the field of epigenetics is almost exclusively focused on studying the mechanisms responsible for sustained gene silencing. To uncouple transcriptoin form maintenance, and gain access to novel epigenetic mechanisms, I am exploring a phenomenon present in innate immunity: transcriptional memory. During this process, cells primed with a certain cue will show increased rates of gene expression after restimulation many days later.

In our previous work, we set up a robust transcriptional memory protocol using interferon gamma (IFNγ) stimulation. We discovered novel genes that show the effect and gained initial insights into the molecular mechanisms controlling initiation of the phenomenon. We discovered locally acting repressors and identified specific transcription factors involved in the establishment of transcriptional memory. Moreover, we showed that initiation of memory is not just a simple consequence of transcription as artificial activation of a memory gene does not lead to memory initiation. We are now in a unique position to understand this epigenetic problem in unprecedented detail. We have the necessary tools, expertise and preliminary data to uncover novel mechanisms of transcriptional memory.

In this project, we want to understand how IFNγ transcriptional memory is initiated on a cellular, molecular and structural levels; generalize the discoveries to maintenance of active transcription and translate the knowledge to macrophage biology. We have four major aims: (1) determine what factors are required for establishment of transcriptional memory; (2) reconstitute the memory initiation complex in vitro; (3) generalize the discoveries to maintenance of active transcription in other cell types; and (4) translate the knowledge to maintenance of macrophage identity, in cell lines and primary cells.

In summary, this project addresses a major knowledge gap and will lead to fundamental discoveries in epigenetics. It will bring about multidisciplinary training of future scientists. Insights from this research will uncover new avenues for manipulation of the innate immune system for the benefit of public health, with particular focus on macrophage based anti-cancer immunotherapies. This will pave the way for industrial collaboration and new jobs in the biotechnology sector.
