520 | _ | _ | |a Matrix metalloproteinases like MMP-13 cleave and remodel the extracellular matrix and thereby play a crucial role in tumor progression in vivo. Using a highly selective inhibitor to block MMP-13 protein activity, we demonstrate a striking inhibitory effect on invasive tumor growth and vascularization in murine skin squamous cell carcinoma (SCC). Therapy outcome critically depends on animal age in C57Bl/6 mice and was successful in old female but not in young female mice. Treatment success was recovered by ovariectomy in young and abolished by 17ß-estradiol supplementation in old mice, suggesting a hormone dependent inhibitor effect. Responsiveness of the tumorigenic keratinocytes BDVII and fibroblasts to 17ß-estradiol was confirmed in vitro, where MMP-13 inhibitor treatment led to a reduction of cell invasion and vascular endothelial growth factor (VEGF) release. This correlated well with a less invasive and vascularized tumor in treated mice in vivo. 17ß-estradiol supplementation also reduced invasion and VEGF release in vitro with no additional reduction on MMP-13 inhibitor treatment. This suggests that low 17ß-estradiol levels in old mice in vivo lead to enhanced MMP-13 levels and VEGF release, allowing a more effective inhibitor treatment compared to young mice. In our study, we present a strong link between lower estrogen levels in old female mice, an elevated MMP-13 level, which results in a more effective MMP-13 inhibitor treatment in fibroblasts and SCC cells in vitro and in vivo. |
