About the Abraham Lab

To produce the right complements of proteins that enable cell type-specific behaviors, cells interpret the instructions in DNA through gene transcription or expression. Proper gene expression depends on complex rules and physical interactions between a multitude of components. Improper transcription of genes or proper transcription of broken genes is central to many human diseases. Our lab is interested in understanding how transcriptional mechanisms are regulated and how they guide cell identity, disease etiology, and therapeutic development.

Our research summary

The Abraham lab studies how gene transcription is controlled, including how the genome is organized in the nucleus and how specific genes are regulated by environmental cues.  We also study how transcriptional processes are altered in disease to either understand the disease or to suggest treatments. We develop and deploy computational pipelines to synthesize and distill complicated transcriptional processes and how they go awry in diseased cells. Much of our work centers on the study of super-enhancers, which are arrangements of transcription-regulating DNA elements that allow genes especially important for a cell's identity to be tightly controlled by the cell's environment. These super-enhancers have proven useful for identifying regulators of cell identity, regulation of genes by signaling pathways, genes required for tumor cell survival, targetable protein nodes in cancers, and important mutations in tumor genomes.  Super-enhancers and their associated genes can be aggregated to computationally model the core regulatory circuitry that maintains the identities of specific cell types. 

Super-enhancers are also physical entities in cell nuclei that are important contributors to structuring the genome within the nucleus. Our goals are to identify loci in the nucleus where transcriptional enhancers interact to form super-enhancers using genome structure data, and to uncover genes regulated by these structures in healthy and diseased cells. We are developing algorithms that leverage high-throughput sequencing data to identify these collections, the genes that they control, and the processes that mediate their functions.

About Brian Abraham

Dr. Brian Abraham received his PhD from the National Institutes of Health/Boston University Graduate Partnership Program in Bioinformatics before pursuing his postdoctoral training at the Whitehead Institute under the mentorship of Dr. Richard A. Young. He joined St. Jude as an Assistant Member in 2019, where he runs a research program focused on understanding how cells interpret the instructions in DNA to contribute to development and disease. Dr. Abraham is a co-investigator in the St. Jude Collaborative Research Consortium on 3D Genomics of Pediatric Cancer alongside other St. Jude faculty, and collaborators from Dana Farber and the Whitehead Institute. In addition to his scientific training, Dr. Abraham has a rich history in science writing and teaching. He is the Course Director of Computational Biology, for the St. Jude Graduate School of Biomedical Sciences and a member of the Cancer Center’s Neurobiology and Brain Tumor Program. He received his undergraduate degrees from Rochester Institute of Technology.
