Abstract:
:Amplification of 8p11-12 in human breast cancers is associated with increased proliferation and tumor grade and reduced metastasis-free patient survival. We identified Zeppo1 (zinc finger elbow-related proline domain protein 1) (FLJ14299/ZNF703) within this amplicon as a regulator of cell adhesion, migration, and proliferation in mammary epithelial cells. Overexpression of Zeppo1 reduces cell-cell adhesion and stimulates migration and proliferation. Knockdown of Zeppo1 induces adhesion and lumen formation. Zeppo1 regulates transcription, complexing with Groucho and repressing E-cadherin expression and Wnt and TGFβ reporter expression. Zeppo1 promotes expression of metastasis-associated p120-catenin isoform 1 and alters p120-catenin localization upon cell contact with the extracellular matrix. Significantly, Zeppo1 overexpression in a mouse breast cancer model increases lung metastases, while reducing Zeppo1 expression reduces both tumor size and the number of lung metastases. These results indicate that Zeppo1 is a key regulator of breast cancer progression.
