Research profile

Sang Eun Lee, Ph.D.

Professor

The common property of cancer cells is genetic instability.  Frequent alterations of structure and chromosome numbers in cells contribute to the initiation and the progression of many types of cancer. The ultimate cure of this disease should thus come from a better understanding of the mechanisms preserving genome integrity. The overarching goal of my research program is to define cellular mechanisms to suppress genetic instability in the face of DNA damaging agents, in particular, DNA double strand breaks.

    Federal

    Funding Agency NIH Title Hypovitaminosis D promotes MED12-associated genomic instability in uterine fibroids Status Active Period 8/2017 - 7/2022 Role Co-Investigator Grant Detail : Vitamin D3 signaling modulates the level of DNA damage, including that likely arising from R-loop induced replication stress, in MED12 mutation positive uterine fibroids. These findings provide sound support to investigate whether, and also how, low vitamin D3 levels, a known risk factor for uterine fibroid development, compound DNA damage accumulation and genetic instability found in MED12 mutant tumors.

    Private

    Funding Agency William and Ella Owens Medical Research Foundation Title Targeting Microhomology-Mediated End Joining to sensitize recombination-deficient cancer cells. Status Complete Period 1/2016 - 6/2017 Role Principal Investigator Grant Detail
