Stage M2: The role of miRNA in myogenic cell communication in response to ionizing radiation H/F

Nanterre, Île-de-France IRSN Temps plein

Mission

Cell-to-cell communication is crucial for tissue homeostasis, enabling it to respond to stress, such as irradiation. MicroRNAs (miRNAs) play a key role in this process by regulating gene expression in target cells.
The main objective of this internship is to validate preliminary data identifying potential candidate miRNAs found in cell culture supernatants after irradiation of myogenic cells. To achieve this, the candidate will improve the characterization of the expression profile of a panel of candidate miRNAs by quantitative PCR on samples of the murine myogenic C2C7 cell line and compare the profiles obtained between the different myogenic differentiation stages, i.e. myoblasts (proliferative cells), myocytes (differentiated cells) and myotubes (differentiated and polynucleated cells) exposed to different doses of irradiation.
At the end of the internship, the candidate could examine the communication impact of the modulation of some of these miRNAs on the different myogenic cells, in terms of cell survival by using MTT assay and activation of DNA damage response by immunostaining.

Profil recherché

This internship will allow the selected student to improve their technical skills in cell biology and molecular biology. In addition, the candidate will acquire solid knowledge in exposure to ionizing radiation, as well as their consequences on eukaryotic cells.
We are seeking for highly motivated Master 2 student in biology / health sciences, with good knowledge in cellular and molecular biology.
