Cell cycle checkpoint pathways and molecular genetics studies of breast cancer using mouse model systems
Eva Lee and her laboratory continue to conduct investigations on tissue-specific functions of breast and ovarian cancer susceptibility genes, BRCA1 and BRCA2, and interactions between tumor suppressors and endocrines. Dr. Lee's group demonstrated that inhibition of the stabilized progesterone receptor in BRCA1 and p53-mutated mammary epithelial cells prevented or delayed mammary tumors. Her team has continued to focus on the mechanisms of progesterone receptor stabilization as well as the usage of anti-progesterone in breast cancer prevention and progesterone receptor positive breast cancer treatment. How mutations of BRCA genes affect mammary epithelial cell fates and mechanisms of cancer stem cells expansion during the course of chemo-resistance are being studied.
In addition, Eva Lee and her laboratory investigate the interaction among checkpoint kinases and DNA repair proteins in the maintenance of genomic stability. Her team demonstrated functional links between ATM and NBS1. They have identified novel mediator, Cep164, for the ATM and ATR signaling pathways that guard genomic stability. How Cep164 network leads to S and G2/M checkpoint activation is being investigated.
