Régulation des gènes des mammifères par de nouvelles classes de sites de départ de la transcription proximale du promoteur
Regulation and fidelity of gene expression is fundamental to the differentiation and maintenance of living organisms. Moreover, understanding how genes are regulated is an essential research question of importance for biomedical application. Although our knowledge about key factors influencing gene expression has increased substantially over the past years, the complexity of gene expression regulation remains elusive. In this project, I intend to discover novel gene expression regulatory circuits operating in mammalian genomes facilitated by pervasive transcription. Although some scattered examples of how pervasive transcription may regulate gene promoter activity exist, no systematic study has been conducted. Here, I will address this question by using a new protein depletion strategy, developed in the host laboratory, to inactivate the nuclear exosome, a major 3’-to-5’ ribonuclease complex, and its co-factors in HeLa and mouse embryonic stem (mES) cells, thus, to create an ideal situation to observe ‘hidden’ cellular transcription events, which would not normally be visible. I intend to assess whether and how this ‘hidden’ transcription contributes to the regulation of promoter activity in HeLa and mES cells, further expanding our knowledge of the regulation of protein-coding genes and ultimately revealing the extent of regulation instigated by pervasive transcription. This study will lay a foundation for future research in the field and at the same time provide novel conceptual information, which might be exploited in prevention or treatment of human diseases.
