Research Interests
As a member of the Hendrix Laboratory, I am interested in determining the molecular mechanisms of metastasis. I am specifically interested in the role of lysyl oxidase (LOX) in breast cancer cell motility. LOX is a copper-dependent amine oxidase that catalyzes cross-linking of collagens and elastins within the extracellular matrix. However, LOX has recently been localized within the cytoplasm and nucleus of cells, in addition to the cell membrane. LOX has been shown to have a role in gene differentiation/regulation as well as motility/migration. Moreover, LOX is highly upregulated in invasive breast cancer cells compared to their poorly invasive counterparts. Therefore, I am studying the ability of LOX to facilitate cell motility through the regulation of cell adhesion formation, actin filament polymerization, and gene transcription. My work in the laboratory has shown that LOX facilitates cell motility/migration through changes in cell adhesion formation. Specifically, these changes occur via regulation of the FAK/Src signaling pathway through a hydrogen peroxide-mediated mechanism. Additionally, I have shown that LOX facilitates actin filament formation and regulates the activation of the Rho family GTPases. Finally, I have demonstrated that LOX regulates NF-kB activity which may lead to changes in gene transcription regulation.
