# Laurent Susini

Laurent Susini (born April 18, 1965) is a French molecular biologist; his research is in the area of cancer and the genetic basis of tumor reversion.

## Career

Laurent Susini started at the Centre d'Etude du Polymorphisme Humain (Fondation Jean Dausset-CEPH). He obtained his PhD in Human Genetics and Molecular Biology from University Paris VII - Denis Diderot.
He collaborated with research teams from Caltech and the Los Alamos National Lab. as a member of Pr Daniel Cohen [fr]'s team at Genethon and at Genset Corporation to contribute to the first physical map of the human genome.
At the Weizmann Institute of Science, in the Lab of Professor Moshe Oren, he demonstrated that SIAH1 induces ubiquitin-mediated degradation of NUMB (gene), a protein that influences cell fate decisions. SIAH1 a p53-inducible gene, plays a role in both cell death and tumor suppression by targeting specific proteins for proteasomal degradation via ubiquitination.
Approaching cancer research with a different angle, not asking why the normal cells become malignant, but rather from the patients expectations: how do my tumor cells quit their malignant status, and thus, revert?, Laurent Susini joined Molecular Engines Laboratories (M.E.L.), a biotech company with headquarters and laboratories located in Paris (France), in 2000, to develop a new generation of innovative drugs against cancer with Adam Telerman and Robert Amson.
By analyzing gene expression and using bio-informatics on cellular models of tumor reversion, M.E.L. researchers identified over 200 genes involved in the process, including TCTP (Translationally Controlled Tumor Protein / Translationally Controlled Tumour Protein. This research has led to the potential development of drugs for cancer prevention and management by inhibiting tpt1/TCTP gene expression.
Laurent Susini joined Oncology Clinical Research in 2007 to contribute to the early clinical development of anti-cancer drugs. He worked first with Quintiles and later joined the Translational Clinical Oncology department at the Novartis Institutes for BioMedical Research, where he designed and conducted phase I clinical trials primarily in melanoma and hematology malignancies.

## Research

Laurent Susini has played a critical role in the research of M.E.L founded by Adam Telerman and Robert Amson. More particularly his expertise was instrumental for the genetic and epigenetic analyses of single revertant cells from different cancer cell lines, for the identification of a "drugable" target and for the generation of pharmacological compounds able to kill cancer cells.
TCTP (Translationally Controlled Tumor Protein was identified in a screen between tumor cells and revertant cells. Inhibition of TCTP influences reversion of tumor cells. Therefore, the objective was to develop drugs targeting TCTP in cancers overexpressing the protein.
Translationally Controlled Tumor Protein (TCTP/tpt1) is a regulator of the tumor reversion program, tumor progression and certain forms of inflammatory diseases. Laurent Susini described TCTP as a pro-survival protein antagonizing BAX, Bcl-2-associated X protein, function
