Transposable elements, their controllers and the genesis of human-specific transcriptional networks

Objective

Transposable elements (TEs) account for more than two thirds of the human genome. They can inactivate
genes, provide novel coding functions, sprinkle chromosomes with recombination-prone repetitive
sequences, and modulate cellular gene expression through a wide variety of transcriptional and
posttranscriptional influences. As a consequence, TEs are considered as essential motors of evolution yet
they are occasionally associated with disease, causing about one hundred Mendelian disorders and possibly
contributing to several human cancers. As expected for such genomic threats, TEs are subjected to tight
epigenetic control imposed from the very first days of embryogenesis, in part owing to their recognition by
sequence-specific RNA- and protein-based repressors. It is generally considered that the evolutionary
selection of these TE controllers reflects a simple host-pathogen arms race, and that their action results in the
early and permanent silencing of their targets. We have recently uncovered new evolutionary evidence and
obtained genomic and functional data that invalidate this dual assumption, and suggest instead that
transposable elements and their epigenetic controllers establish species-specific transcriptional networks that
play critical roles in human development and physiology. The general objective of the present proposal is to
explore the breadth of this phenomenon, to decipher its mechanisms, to unveil its functional implications,
and to probe how this knowledge could be exploited for basic research, biotechnology and clinical medicine.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

ERC-ADG - Advanced Grant

Host institution

ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
