Research Areas
Lab Research: The compartmentalization of mitochondrial DNA results in distinct mechanisms for maintenance of its genome and cellular response to injury. Modulation of the mitochondrial isoform of dUTPase can be used to shift the nucleotide pools and cause uracil misincorporation. One goal is to down regulate this enzyme to examine its role in maintenance of mitochondrial genomic integrity and also to analyze its affect in response to chemotheurapeutics.
A second area of interest is nuclear DNA repair during the cell cycle. The nuclear isoform of uracil-DNA glycosylase cycles with the cell cycle and seems to be most prevalent during G1 & S phases. Post-translational modification may be important in unraveling the distinct cellular controls that tightly regulate the presence or absence of this enzyme to remove uracil from DNA.
