Outline of Final Research Achievements

This research aims to develop an experimental system in which nuclear envelope (NE) can be artificially assembled around a biomolecule-coated bead in a living cell. Live cell imaging-associated correlative light and electron microscopy of the beads coated with candidate molecules which are known to act as a seed of NE formation in the cell extract-based NE reconstitution experiments revealed that DNA-bound and BAF-bound beads can assemble nuclear envelope-like membranes around the beads in living cells. Further studies about the NE-like membranes formed around the DNA-coated beads revealed that BAF-mediated assembly of the NE-like membranes leads to exogenous DNA avoiding autophagy. Based on these results we conclude that our bead-mediated system can be used to induce and dissect the process of NE assembly in living cells.
