Postdoctoral Position in Pediatric Cancer (F/M)

About us Institut Curie is a major player in the research and fight against cancer. It consists of a Hospital group and a Research Center of more than 1000 employees with a strong international representativeness. The objective of the Research Center is to develop basic research and to use the knowledge produced to improve the diagnosis, prognosis, and therapeutics of cancers as part of the continuum between basic research and innovation serving the patient. Mission Laboratory The “Signaling and Cancer Progression” team, led by Celio Pouponnot, investigates signaling pathways and their impact on transcription factors in cancer, using biochemical and functional experimental approaches both in vitro and in vivo. Our research focuses on pediatric brain tumors, particularly medulloblastoma (Garancher et al., Cancer Cell, 2018; Morabito et al., EMBO Molecular Medicine, 2019; Mirabal-Ortega et al., Nature Communications, accepted). Our team has developed and uses genetically engineered mouse models and patient-derived xenografts to study pediatric brain cancers, particularly medulloblastoma (MB). Our current research aims to elucidate the mechanisms underlying treatment resistance, particularly resistance to radiotherapy, and to identify actionable molecular vulnerabilities in pediatric brain cancers. The project Medulloblastoma (MB) is the most common malignant brain tumor in children. Among the four molecularly defined groups, Group 3 (G3) is associated with a poor prognosis. Despite recent advances, our understanding of G3 remains limited, notably due to the lack of models that allow the study of tumor initiation and interactions with the immune system. The project aims to generate and characterize immunocompetent mouse models of G3 MB, including genetically engineered mouse models and models based on the in vitro transformation of cerebellar progenitors, followed by orthotopic transplantation into the cerebellum. These models will enable the study of the different steps of tumor transformation and alterations in developmental programs. Multimodal analyses, including lineage tracing, bulk and single-cell transcriptomic analyses (scRNA-seq), will be performed to validate and characterize these models. These models will enable us to investigate how oncogenes initiate tumorigenesis, disrupt normal development, and shape the immune microenvironment, as well as to test new therapeutic strategies.
