Nuclear envelope dynamics

Our research focuses on the nuclear envelope, the main line of defense for our genome.


Composed of a double lipid bilayer and a host of associated proteins, the nuclear envelope (NE) encloses the genome and physically separates the nuclear compartment from the rest of the cell. Transport across this barrier is controlled by molecular gateways called nuclear pore complexes, while underlying lamina filaments support nuclear shape and plasticity.

In addition to providing a physical barrier, the NE spatially orchestrates a range of cellular processes, mediates signal transduction, and organizes chromatin functionalization. Long considered a static entity, it is becoming clear that the nuclear envelope undergoes rapid changes in shape, integrity, and associated proteome following extracellular and intracellular cues. These changes can trigger a variety of signaling cascades that in turn affect cellular function. We are only just beginning to understand the many dynamic processes that are orchestrated by the nuclear envelope and how these affect cell fate.

About the group

The Nuclear envelope dynamics group aims to characterize pathways triggered by changes in NE topology, and to understand how such pathways affect cell fitness and fate.

Our research focuses on

  • mechanistic regulation of NE integrity during cell division, interphase, and in micronuclei.
  • effects of compromised NE integrity on genome integrity, cell fitness and fate.
  • consequences of genetic defects (e.g. cancer and envelopathies) on NE function and integrity.
  • responses of the NE to non-genetic triggers such as mechanical stresses and their effects on cellular processes.

To address these questions, we use mechanistic cell biological studies that revolve around live-cell microscopy, proteomics, and genetics approaches in non-transformed cell lines, cancer cell lines, as well as primary cell models.

Movie 1: Cells undergo transient lapses in nuclear integrity. Nuclear ruptures are monitored by leakage of a nuclear fluorescent marker into the cytosol (in red, mCherry-NLS). These ruptures are accompanied by transient recruitment of the nuclear membrane repair machinery to the sites of rupture (in green, CHMP4B-mNG) resulting in restoration of nuclear integrity as evidenced by nuclear re-accumulation of mCherry-NLS.
