Description of Research
Summary Statement of Research Interests
Detailed Statement of Research Interests
Professor Forsburg studies how chromosome duplication and maintenance contributes to overall genome stability in a model genetic system, the fission yeast Schizosaccharomyces pombe. Fission yeast is a simple, single-celled organism with chromosomes very similar to those in humans, and has proven to be an important model for cell division.
Forsburg takes a holistic approach to studying how DNA replication stress contributes to genome stability. Ongoing studies address the role of the MCM helicase in maintaining the structure of the replication fork; the function of recombination and repair proteins in maintaining genome structure during S phase, including during meiosis; and the contribution of chromatin-modifying proteins to replication and repair.
The Forsburg lab uses a mixture of classical genetics, molecular biology, and state-of-the-art microscopy to investigate how defects in replication contribute to genome instability during normal cell growth and during the differentiation process of meiosis. Recently, the group identified the centromere as a natural fragile site in the genome, particularly when the replication fork is disrupted. As part of this project, a novel chromosome translocation was identified, which provides a model for Robertsonian translocation. Additionally, a novel replication mutant generates micronuclei. These are a feature of cancer cells and this provides a powerful yeast model to examine micronucleus formation and resolution, and their contribution to gross chromosome rearrangements. Finally, cells in meiosis are uniquely vulnerable to replication stress and genome instability, leading to chromosome mis-segregation and spore lethality.
The group employs advanced imaging methods to complement their classical genetics, using widefield deconvolution microscopy. A particular strength is the ability to perform live-cell studies with fluorescent proteins in real time that allows single cell analysis. Using microfluidics technology, cells can be imaged during treatment with genome destabilized agents, and then during recovery. Additionally, the lab is doing high-throughput analysis of visual markers in a library of mutant straiuns. Forsburg's group is also developing technology for single-molecule imaging of replication forks on intact chromatin fibers.
