Abstract |
The transcription factor Runx2 has an established role in cancers that metastasize to bone. In metastatic breast cancer cells Runx2 is overexpressed and contributes to the invasive capacity of the cells by regulating the expression of several invasion genes. CBFbeta is a transcriptional co-activator that is recruited to promoters by Runx transcription factors and there is considerable evidence that CBFbeta is essential for the function of Runx factors. However, overexpression of Runx1 can partially rescue the lethal phenotype in CBFbeta-deficient mice, indicating that increased levels of Runx factors can, in some situations, overcome the requirement for CBFbeta. Since Runx2 is overexpressed in metastatic breast cancer cells, and there are no reports of CBFbeta expression in breast cells, we sought to determine whether Runx2 function in these cells was dependent on CBFbeta. Such an interaction might represent a viable target for therapeutic intervention to inhibit bone metastasis. |
