Abstract

To determine whether tumor-derived CCL5 contributes to the metastatic potential of murine mammary carcinoma, we used the 4T1 tumor which spontaneously metastasizes and constitutively produces CCL5. Mice bearing 4T1 that expressed less CCL5 had significantly fewer lung and liver metastasis. The decrease in tumor-derived CCL5 also correlated with decreased cathepsin L, MMP-2, MMP-3, MMP-10 and MMP-17 gene expression. Thus, inhibition of tumor-derived CCL5 can impact the metastatic capability of 4T1 and may do so by modulating protease expression.
