Violaine MOREAU PhD, Cancer cell biologist

Course and current status

Violaine Moreau is a research scientist at Inserm since 2002 and a research director (DR2) since 2014. She is experienced in the direction of researches and organizations: group leader during 13 years, she heads the “Liver Cancer and Tumor Invasion” Inserm team since 2016. After being appointed, in 2020 at the direction of the Inserm Unit 1053, for two years, she is now deputy director of the BoRdeaux Institute of onCology (BRIC) Unit 1312, a multi-team Inserm unit dedicated to cancer research at the University of Bordeaux.

Scientific summary

The main focus of V. Moreau research is the involvement of RhoGTPases and their regulators in cell motility. Her interest in actin cytoskeleton and small GTPases is long-standing.

For many years, her work focused on the regulation of actin polymerization, working on the Arp2 protein during her PhD in Strasbourg and on N-WASP and WIP proteins during her post-doc in M. Way's laboratory at EMBL (Heidelberg). This work describing the basic mechanisms of actin polymerization led to a series of high impact papers.

Moreover, she started to study GTPase signaling during her post-doc, while using the vaccinia virus as a model. She then developed a strong expertise in RhoGTPase signaling and invadosomes in Bordeaux. In 2007, she joined Jean Rosenbaum’s laboratory (Bordeaux) and focused her work on the study of small GTPases in liver cancer.

Currently, the project of the team, she is co-leading with F. Saltel, focuses on the 3 following axes: 1) Precancerous lesions and mediators of liver carcinogenesis; 2) Molecular bases of tumor invasion and 3) Biomarkers for liver cancers.
