Is the Runx transcriptional co-activator , CBFbeta , essential for invasion of breast cancer cells?
CBFbeta is expressed in metastatic breast cancer cells and is essential for cell invasion. CBFbeta is required for expression of several Runx2-target genes known to be involved in cell invasion. However, whilst CBFbeta is essential for invasion, not all Runx2-target genes require CBFbeta. We conclude that CBFbeta is required for a subset of Runx2-target genes that are sufficient to maintain the invasive phenotype of the cells. These findings suggest that the interaction between Runx2 and CBFbeta might represent a viable target for therapeutic intervention to inhibit bone metastasis.
