| Research Abstract |
Crosstalk between cancer cells and bone microenvironments is critical to the development and progression of bone metastases. To determine the molecular basis of bone metastasis, we attempted to uncover the molecules that are expressed in breast cancer cells under the influences of bone microenvironments. We have identified 154 genes by microarray analysis. We found that docking protein NEDD9 that is up-regulated by bone-derived TGF・・is critical to the development of bone metastasis. Further determination of the function of genes identified by this study may lead to design new molecular therapeutic approaches for the treatment of bone metastasis.
