Mechanisms of lung tumorigenesis driven by heme signaling and protein degradation machinery
The goal of this project is to discover the molecular mechanisms regulating the heme-FBXO22 pathway, to identify its targets, and to determine their role in lung cancer pathogenesis. The results of this study will be determinant to identify specific cancer vulnerabilities driven by alteration of the heme pathway that could be exploited for the design of new and more effective therapies to be used in the clinic.

DNA damage and genome instability
Our overall goal is to understand how the cells deal with this damaged DNA. We aim at understanding the mechanisms that regulates thebalance between error-free (Damage avoidance) and mutagenic (translesion synthesis) DNA damage tolerance mechanisms

CADHERINS AND PANCREATIC CANCER AGRESSIVENESS
The objective of the proposed thesis is to determine if the nature of adhesion molecules, mainly cadherins, expressed in pancreatic ductal adenocarcinoma (PDAC) represents a signature of tumor aggressiveness. It aims to determine whether these molecules impact migration, invasion and metastasis of tumor cells. Particular attention will be paid to the ability of cadherins to regulate the stability and activity of membrane microstructures called invadopodia. These structures, involved in the degradation of the extracellular matrix, are most likely involved in tumor metastasis.More
IMPACT OF MEDULLARY ADIPOCYTES ON THE PROGRESSION AND CHEMORESISTANCE OF MYELOID LEUKEMIAS
Mast cell leukemia (ML) is a highly aggressive blood cancer characterized by the excessive proliferation of immune cells called mast cells (MC) in the bone marrow. The prognosis for patients with SCI is extremely poor (less than 6 months) and resistance to cytoreductive therapies and tyrosine kinase inhibitors is common. The risk of developing SCI is higher in elderly subjects who generally have more fatty tissue in the
bone marrow than younger subjects. Because of the potentially inflammatory nature of bone marrow adipose tissue and its ability to act as a source of fatty acids and adipokines, we want to study how bone marrow adipose tissue leukemic mast cells and modulate disease progression and resistance to standard therapies in order to develop better to develop better treatment options for SCI patients.
Dynamic of replication of telomeric sequences
The aim of the project is to further investigate the molecular mechanisms which ensure the stability of repeated sequences in the yeast S. pombe, focusing on the mechanism of fork stabilization and fork restart. The main techniques used in the laboratory are: the genetics of the yeast S. pombe, PCR, cloning, Western blot, Southern blot, co-immuniprecipitation (CoIP), chromatin immunoprecipitation (ChIP), two-dimensional DNA gel, yeast two-hybrid,….

Polymorphism and recombination
Our project combines molecular genetics and yeast genomics approaches, including a significant amount of bioinformatics analysis of NGS data and recombination profiles in which the lab has strong experience (Marsolier-Kergoat et al. 2018). Our goal is to better understand the balance between repair and rejection of the "heteroduplex" DNA that forms when two polymorphic molecules recombine with each other. Such a balance controls both meiotic allelic shuffling, but also mitotic and meiotic non-allelic recombinations that cause major chromosomal rearrangements. This project is therefore of great interest in the fields of genome evolution and genomic instability responsible for many human diseases, including cancers.
