CANCER FROM WITHIN: immune cells reveal insights into mechanisms of DNA recombination and tumorigenesis. Lymphocytes are unique cell types of our adaptive immune system that require multiple rounds of cell divisions during their development and, most strikingly, multiple rounds of gene rearrangements during the formation of their antigen receptors. Our research major goal is to understand the mechanisms by which a lymphoid cell maintains the integrity of its DNA and prevents genomic instability and transformation. We study the DNA recombination processes – V(D)J recombination and class switch recombination – that are part of B- and T-cell development and the general DNA double-strand break response and repair mechanisms and pathways that lead to genetic instability and cancer.
Study of DNA double-strand break repair regulation in B cells – implication for cancer therapy
Cancer cells frequently harbor somatic mutations leading to altered DNA repair pathways. In some cases, these defects can be therapeutically exploited as these tumor cells, but not healthy cells, rely on compensatory DNA repair […]
Mechanisms and consequences of chromosomal translocations
Chromosomal translocations can promote cancer development by disrupting tumor suppressors, activating oncogenes, or generating aberrant fusion proteins. Fusion genes are frequent in cancers and are used as diagnostic and prognostic tools to classify and […]
Think tank: Cancer
The malignant transformation of cells translates into a major worldwide health, social and economic burden. Efforts to define the etiology of cancer, along with the development of new therapeutic approaches to treat them, would […]
Deciphering the Oncogenic Lesions and Pathways of B and T Cell Cancers
FROM PHYSIOLOGICAL DNA REARRANGEMENTS TO LYMPHOID CANCERS
B and T cell lymphoid cancers are among the most common human malignancies. Many factors, endogenous and exogenous, are implicated in the etiology of these disorders, but key oncogenic lesions often arise through […]
MECHANISMS OF DNA RECOMBINATION
DNA double-strand breaks (DSBs), although common, are extremely dangerous (Deriano and Roth, Annual Review of Genetics, 2013). Unlike most other DNA lesions, DSBs directly threaten genomic integrity by disrupting the physical continuity of […]
Drug Discovery & Screening at Institut Pasteur
The Technological Targeted Action Drug Discovery and Screening (ATC-DDS) coordinates projects and collaborations at the Institut Pasteur Paris campus on therapeutic development. It raises awareness for DDS in basic research projects and stimulates intra-campus […]
With more than 19.3 million new cases in 2020 worldwide, including nearly 400,000 in France, cancer is a common disease that affects or will affect us all one day, directly or indirectly. It is […]
