My laboratory focuses on genetic events that contribute to breast hyperplasia, breast cancer progression, and chemotherapy resistance. We have developed a model that starts with normal human mammary epithelial cells (HMECs) and uses four distinct genetic alterations, including inactivation of tumor suppressors p16INK4a and p53 and elevated expression of MYC and oncogenic HER2 or RAS, to transform normal HMECs and interrogate epithelial specific tumor-suppressive signaling. This model allows us to define how oncogene activation dismantles suppressive signals to drive transformation and cancer progression. We also define the contribution of cytokines to the transformation process, and the epithelial-mesenchymal plasticity and cancer stem cell properties associated with breast cancer progression and chemotherapy resistance. Combined with studies of genetically engineered mouse models, patient-derived xenografts, and publically available datasets, our research is identifying novel components involved in breast cancer development and progression.

Research highlights include:

  • Defining the role of the MDMX gene as a p53 inhibitor, resulting in identification of a small molecule inhibitor of MDMX that can synergize with Nutlin-3 to suppress cancer harboring wild-type p53. This novel compound may one day be developed as a cancer treatment.
  • Developing a set of validation-based insertional mutagenesis (VBIM) lentiviral vectors to identify novel genes that confer resistance to targeted therapy and chemotherapy including paclitaxel, quinacrine, and erlotinib; regulate NFĸB activators and inhibitors; promote RAS-mediated senescence; and drive HMEC transformation. We are developing high-throughput screening strategies using DNAseq and RNAseq technologies to identify VBIM insertion sites and track whether they are enriched or depleted in selected populations.
  • By merging our HMEC transformation model with a VBIM forward genetic screen, we recently identified the FAM83B oncogene. FAM83B is one of eight members the FAM83 protein family, and each is significantly elevated in numerous cancer types. Our findings provide new therapeutic targets that may potentially impact not only breast cancer, but cancer in general.
