Research Interests  
  In 2003, the 5-year survival rate was 97% for patients with localized breast cancer. However, the 5-year survival rate for breast cancer patients with regional tumor invasion decreases to 78%, and to 23% for women with distant metastases. The decreased survival rates for women with regional invasion and distant metastases demonstrates our lack of understanding of breast cancer biology and disease progression, and accentuates the need for directed anti-invasive/metastatic therapeutic modalities. Therefore, it is critical to determine the molecular mechanism(s) of breast cancer metastasis (i.e. molecular markers that definitively distinguish tumors of non-metastatic potential from those with metastatic potential). To identify such invasion/metastasis-associated genes, we utilized differential display to compare mRNA expression in highly invasive/metastatic breast cancer cell lines to that expressed in poorly invasive/non-metastatic breast cancer cell lines. Using this technique we identified lysyl oxidase, which is up-regulated in invasive/metastatic breast cancer cells.
Lysyl oxidase (LOX) belongs to a family of copper-dependent amine oxidases that catalyze the oxidative deamination of peptidyl-lysine and hydroxylysine to reactive semialdehydes. Traditionally, LOX has been shown to initiate the covalent cross-linking of collagens and elastin in extracellular matrices. However, recent evidence suggests that LOX is a multifunctional or “moonlighting” protein. LOX has been shown to induce motility and migration in monocytes, vascular smooth muscle cells, and fibroblasts. In addition, a role for LOX in transcriptional gene regulation has been implicated as evidenced by localization of LOX protein and enzymatic activity to cell nuclei, utilization of histone H1 and H2 as substrates, and activation of the collagen III alpha1 promoter through LOX-induced binding of Ku antigen.
We have shown that LOX facilitates motility and invasion in breast cancer cells through a hydrogen peroxide-mediated mechanism, which activates the FAK/Src signaling pathway leading to the activation of Rac and Cdc42 (Rho GTPases). These results demonstrate that LOX facilitates breast cancer cell motilty by regulating actin filament formation. Our research continues to identify the extracellular and intracellular cues that modulate LOX expression and activity in invasive/metastatic breast cancer cells, including potential protein binding partners and novel enzymatic targets of LOX .
