Réparation de cassures d'ADN dans des cellules cancéreuses HeLa

DNA breaks in HeLa cells marked with bromodeoxyuridine (BrdU), a molecule used to determine the phase in a cell's division cycle, observed using fluorescence microscopy. In this case, scientists are studying post-break DNA resynthesis. Cancer cells have a high proportion of breaks in their DNA. Therapeutic agents used in cancer treatment inhibit the repair pathways for such breaks. Researchers are therefore studying these repair pathways.

CNRS Images,

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
