This is a full-time, fixed-term three-year postdoctoral position, offered under Inserm terms and conditions of employment.
The research team
« Metabolism, Cancer and immune responses », led by Jean-Ehrland Ricci is based at the Centre Méditerranéen de Médecine Moléculaire (C3M), Inserm U1065, in Nice, France (https://www.c3m-nice.fr/equipes/equipe-03/). The team is a highly interactive group comprising PhD students, engineers, research scientists and clinicians.
Our research focuses on understanding the metabolic adaptations that drive cancer development and progression, with the aim of identifying metabolic vulnerabilities that can be exploited for therapeutic intervention. We are particularly interested in the interplay between cancer metabolism and nutritional stress imposed by the tumor microenvironment, in the context of highly aggressive hematological malignancies. The team offers a stimulating and collaborative research environment, with strong expertise in cancer biology, metabolism and immunology, and close interactions among researchers with complementary backgrounds.
Project scientific context and summary
This project will investigate how nutritional stress-induced by the chemotherapeutic agent L-asparaginase (ASNase) rewires tumor metabolism in several subcellular compartments and promotes DNA damage and therapeutic resistance in malignant B cells. Using a validated B-cell lymphoma model of secondary ASNase resistance, the researcher will explore metabolic alterations across mitochondria, cytosol, and nucleus. The project will first aim to determine how ASNase induces oxidative stress and redox imbalance. The researcher will also investigate how ASNase-induced metabolic perturbations affect DNA damage, replication stress, and DNA repair pathways. A combination of genetic and pharmacological approaches, confocal imaging, flow cytometry, metabolic assays, metabolomics, proteomics, and stable-isotope tracing will be used. Compartment-specific analyses of mitochondrial and nuclear metabolism will uncover previously unrecognized metabolic adaptations to ASNase treatment. The functional relevance of candidate pathways will be validated both in vitro and in vivo. The project offers an exciting opportunity to work at the interface of cancer metabolism, mitochondrial biology, DNA repair, metabolomics, and therapeutic resistance.
The successful candidate will contribute to the development of an INCa PLBIO-funded project, conducted in close collaboration with academic partners in Lyon and Paris.
Missions
- To refine and develop research objectives in interaction with the project leaders, contributing to the scientific direction of the project.
