2 recent publications using the laser irradiation and photoablation systems available on the MRic facility from the Bretagne-Loire Node are presented here:

• Esmangart de Bournonville and Le Borgne (IGDR) characterized the assembly and interactions of tricellular junction components in Drosophila epithelial cytokinesis using laser ablation on a SP5 confocal. Their article entitled “Interplay between Anakonda, Gliotactin, and M6 for Tricellular Junction Assembly and Anchoring of Septate Junctions in Drosophila Epithelium” was published last august in Current Biology (https://doi.org/10.1016/j.cub.2020.07.090).

• Rebecca Smith, post-doc in Sébastien Huet’s team (IGDR) in collaboration with Szilvia Juhász from Gyula Timinszky’s team (Szeged, Hungary) used laser irradiation to study chromatin remodeling following DNA damage. Their paper entitled “The chromatin remodeler ALC1 underlies resistance to PARP inhibitor treatment” has just been accepted in Science Advances.
