Adjunct Research Assistant Professor

Research area includes breast cancer treatment.

Current Research
Breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. It is essential to better understand the mechanistic actions by which breast cancer occurs in order to develop new treatments. Therefore, my research is aimed at further elucidating the molecular pathways involved in the pathogenesis of breast cancer. For example, aberrant activation of the Wnt/beta-catenin signaling pathway contributes to the genesis of breast cancer.
I am interested in the secreted frizzled-related proteins (SFRPs) because they are a family of proteins that antagonize Wnt signaling and loss of SFRP expression is found in a multitude of cancers, including breast cancer. Our lab is investigating whether low SFRP levels might lead to breast cancer development in both humans and mice. I am currently utilizing a SFRP1 knockout mouse model to determine whether SFRP loss renders the mammary gland more susceptible to breast cancer development.
Additionally, we are manipulating the expression levels of SFRP in both immortal (non-malignant) mammary epithelial cell lines as well as breast cancer cell lines to determine the mechanisms by which SFRPs influence the various pathways that lead to tumorigenesis since both Wnt dependent and independent pathways are involved. For example, the SFRPs exhibit an apoptotic function in several different tissues and the anti-apoptotic effect of lost SFRP expression has been implicated in carcinogenesis. Therefore, my research also focuses on has SFRPs regulate the pathways that lead to cell death how they might be targeted for breast cancer treatment purposes.
