The nuclear envelope is a regulated membrane barrier that separates the nucleus from the cytosol in eukaryotes. Although the NE is often depicted as a static barrier, new research has identified conditions where nuclear envelope rupturing causes a loss of compartmentalization. Nuclear envelope ruptures are rapidly repaired in the nucleus, but persist at aberrant, nuclear compartments, such as micronuclei and DNA bridges, that form around mis-segregated chromosomes. Compromised nuclear compartmentalization can result in DNA damage, inflammation, and clustered mutagenesis. The Maciejowski lab seeks to understand how the nuclear envelope safeguards the genome and prevents immune recognition of chromosomal DNA. We approach these problems using a combination of cell biology, biochemistry, and genomics. More information about our research can be found at http://maciejowskilab.com/.

Disclosures

Doctors and faculty members often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community.

MSK requires doctors and faculty members to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public.

John Maciejowski discloses the following relationships and financial interests:
