Description of Itmat Expertise

Mitochondrial DNA copy number control, organization, and transmission

Description of Research Expertise

Our primary research focus is on the regulation of mitochondrial chromatin, and its effect on genome segregation, compaction, and expression. By analogy to the nuclear genome, whose regulated compaction/decompaction is an essential aspect of replication, transcription and transmission, regulated compaction of the mitochondrial genome is likely to be a key aspect of mitochondrial biology. The core of our research lies in determining how the mitochondrial genome is maintained and regulated, and how that regulation affects developmental and physiological aspects of mitochondrial function in health and disease. This work has implications in diabetes, aging, heart disease, and mtDNA-borne birth defects.

We have several thrusts in the lab as of now: 1) mutations affecting mtDNA compaction in cardiovascular disease, 2) post-translational regulation of mtDNA compaction, 3) environmental causes of mtDNA depletion and 3) identification and characterization of protein-mtDNA complexes.
