Abstract: | Background PTHrP, a mediator of humoral hypercalcemia of malignancy, is considered as a potential activator to induce breast cancer cells metastasizing to bone. However, recent clinical evidences and basal research results prove that PTHrP expression in primary tumors indicates good prognosis. BMP-6, as a member of TGF-β superfamily, is closely correlated with tumor differentiation and skeletal metastasis. |
