We have developed a model system of late stage metastatic progression by isolating a highly malignant variant of human breast cancer cells from the parental MDA-MB-435 cell line. These cells, isolated from early lung metastasis, displayed increased anchorage independent growth in vitro and when transplanted ortho-topically into nude mice showed accelerated tumor growth rate and early lung spontaneous metastasis when compared to its parental counterpart. These cells, designated as MDA-MB-435-F-L, also showed intense wide spread early skeletal metastasis in vertebrae, mandible, femur, tibia and skull as detected by fluorescence imaging in an experimental bone metastasis model. Gene expression profiles from cDNA microarray showed up or downregulation of the expression of several significant genes regulating angiogenesis, apoptosis, ECM remodeling and metastasis in the MDA-MB-435-F-L cells in comparison to the parental cells. Among the up or downregulated genes, some have also been implicated in the survival of breast cancer patients. As such, the candidate genes selected in this breast cancer progression model system may serve as biomarkers of metastatic progression and also as potential tumor targets for breast cancer therapy.
