Scientific summary

Scientific interests: Gene expression control, Development and homeostasis, Cellular micro-environment.

Until recently, I focused my research on post-transcriptional controls of gene expression during embryonic development. I have characterized the role of the RNA-binding protein CELF1 (previously known as EDEN-BP) in regulating the polyadenylation state, translation and stability of maternal mRNAs in amphibian embryos.

Among the maternal mRNAs controlled by CELF1, I focused my attention on one encoding pEg7/NCAPD2, a non-SMC subunit of the Condensin complex. I have shown that NCAPD2 plays a crucial role in the dynamics of both meiotic and mitotic chromosomes. Beside this, I showed in collaboration with Raphael Métivier, that Cohesin (a complex related to Condensin) is required for the spatial remodeling of the genome upon transcriptional response to estrogens.

More recently, I studied the role of CELF1 in later developmental stages and in tissue homeostasis. Celf1_KO mice exhibit a severe cataract and, based on this finding, I was involved in a project aiming to decipher the role of CELF1 in lens, in collaboration with the Salil Lachke's group (University of Delawware). Beyond this collaborative work, I have identified by RNA-seq the mRNAs whose expression is controlled by CELF1 in lens, and more specifically those regulated at the level of pre-mRNA splicing.

In 2016, I joined the team leaded by Nathalie Theret, whose aim is to decipher the role of adamalysins in TGF-β activity in chronic liver diseases (Fibrosis and Cellular Hepatocarcinoma). For this project, we implement complementary approaches such as cell biology, biochemistry, functional genomics, system biology and modeling.
