The Karpen Lab researches four areas related to chromosome structure and function in higher eukaryotes: 1) centromeric chromatin structure and propagation, 2) regulation of nuclear organization, 3) genomic analysis of heterochromatin (the Drosophila Heterochromatin Genome Project, DHGP), and 4) high throughput assays for identifying environmental agents that cause chromosome loss.

 

We are using a combination of genetic, genomic, biochemical and cell biological approaches to address these fundamental questions. The fly Drosophila melanogaster is our primary experimental system, but we are also exploring the relevance of our findings to other organisms, including humans. Defects in normal chromosome inheritance are involved in the etiology of cancer and birth defects, and increased knowledge of chromosomal mechanisms and molecules are likely to lead to tools for the diagnosis and treatment of human diseases.
