Biologist Researcher: Cellular Responses to Radiation-Induced DNA Damage

Il y a 2 mois


Nanterre, Île-de-France IRSN Temps plein
Job Description

Mission

The primary objective of this project is to elucidate the mechanisms underlying the cellular responses to radiation-induced DNA damage during myogenic differentiation. This involves investigating the impact of ionizing radiation on the DNA repair processes in myotubes, which are polynuclear cells of skeletal muscle tissue, and comparing them to their mono-nuclear precursors, myoblasts.

Key Responsibilities

  • Develop an in vitro myogenic differentiation model to generate multi-nucleated and post-mitotic myotubes with ectopic expression of DNA repair proteins of interest coupled to GFP.
  • Use a microscopy integrated system to induce local DNA lesions within one or more myonuclei and evaluate the treatment with specific DNA repair and cellular communication inhibitors.
  • Assay the survival of different myogenic cells upon irradiation at different doses using MTT assay and analyze the dynamic behavior of GFP-tagged DNA repair proteins using real-time imaging techniques.

Requirements

  • Highly motivated M2 student in biology/health sciences with good knowledge in cellular and molecular biology.
  • Strong inclination for microscopy and experience with immunofluorescence and confocal microscopy techniques.
  • Ability to work independently and as part of a team.

Working Conditions

This internship will be conducted on-site at IRSN's premises in France.

IRSN's Commitment to Diversity

IRSN is committed to promoting diversity and inclusion in the workplace. We welcome applications from candidates with diverse backgrounds and abilities and strive to create an inclusive environment that values and respects all employees.
