RNA BIOLOGY, SIGNALING AND CANCER
Our team focuses on the role of RNA regulations and RNA-binding proteins in cancer biology and anticancer therapy.
We study co-/post-transcriptional gene regulation (most notably intronic polyadenylation and translation) and RNA-binding proteins (RBPs, both canonical and non-canonical) in several aspects of cancer biology and anticancer therapies (genome instability and genotoxic chemotherapy; oncogenic signaling pathways and targeted therapies; T lymphocytes and cancer) and in several cancer types (cutaneous melanoma, breast cancer, acute T lymphoblastic leukemia, non-small cell lung cancer).
To tackle these issues, we use a combination of approaches: biochemical analyses of RNA, proteins and their interactions; genome-wide analyses of RNA regulations (RNA-seq, 3’seq, polysome profiling) and RNA-protein interactions (iCLIP); analyses of cancer cell phenotypes in cell culture; tumor biology in vivo and patients tumors.
Ongoing projects
Axis 1: Response to DNA damage and anticancer therapies.
1.1- Role of intronic polyadenylation (axis led by M. Dutertre).
1.2- Interaction between DNA-damage response proteins and RNA.
Axis 2: Tumor-intrinsic mechanisms of resistance to targeted therapies.
2.1- Dynamic reprogramming of mRNA translation in drug-tolerant cancer cells.
2.2- Direct interaction between MAPK signaling proteins and RNAs.
Axis 3: Crosstalk between tumor cells and their environment.
3.1- T cell receptor-dependent gene regulation in acute T lymphoblastic leukemia.
3.2- Immune-dependent post-transcriptional gene regulation in melanoma.
