Abstract: The cell surface proteoglycan syndecan 1 (SDC1) is overexpressed in the malignant breast stromal fibroblasts, creating a favorable milieu for tumor cell growth. In the present study, we found that ionizing radiation, a well-established treatment in human breast cancer, provokes premature senescence of human breast stromal fibroblasts in vitro, as well as in the breast tissue in vivo. These senescent cells were found to overexpress SDC1 both in vitro and in vivo. By using a series of specific inhibitors and siR…
