The Long Lab, at the ​​Medical University of South Carolina

BRCA1 is an established tumor suppressor that plays a critical role in the development of both sporadic and hereditary breast and ovarian cancer. Considered a “master regulator” of genome integrity, BRCA1 has been linked to nearly all aspects of chromatin biology. Loss of BRCA1 is embryonic lethal and leads to cellular defects in stress signaling, DNA repair, cell cycle progression, apoptosis, chromatin condensation, and gene expression. Each of these processes involves dynamic changes in chromatin architecture that regulate spatial and temporal access to genomic DNA. Although implicated in various mechanisms of chromatin modification and remodeling, a mechanistic understanding of BRCA1’s role in regulating chromatin dynamics has been difficult to establish due to the global consequences of its dysfunction. Using Xenopus egg extracts, my lab seeks to understand how BRCA1 and other chromatin regulators mediate interactions between different biological processes as they compete for access to DNA.
