Title Modulating Bone Marrow Hematopoietic Lineage Potential to Prevent Breast Cancer Bone Metastasis
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary The presence of disseminated tumor cells in patient bone marrow (BM) aspirates predicts decreased recurrence-free survival, yet little is known about whether hematopoietic BM cells impact bone metastases. Here, we report that the BM can be rendered metastasis-suppressive by the bone-targeting bisphosphonate, zoledronic acid (ZA). In particular, ZA modulates hematopoietic myeloid/osteoclast progenitor cell (M/OCP) lineage potential to render them metastasis-suppressive. Granulocyte-colony stimulating factor (G-CSF) promotes resistance to ZA by re-directing M/OCP differentiation. We identified BM transcriptional programs that associate with metastasis suppression and resistance to ZA. Analysis of patient blood samples taken at randomization revealed that women with plasma G-CSF levels >23 pg/mL experienced significantly worse outcome with adjuvant ZA than those on ZA who had lower plasma G-CSF levels. Our findings establish that hematopoietic cells and M/OCP lineage potential profoundly impact bone metastasis and support the discovery of biomarkers that stratify therapeutic responses in patients at risk of recurrence.
Overall design To test in murine bone marrow and osteoclast precursor cells the effects on gene expression of treatment with ZA and G-CSF. At least two replicates from each treatment were used (including no treatment and combination treatment) and analyzed in a pairwise fashion.
