Abstract:
PURPOSE:Human chondrosarcomas are generally resistant to conventional treatments like chemotherapy and radiotherapy. We investigated the effects of BIBR1532, an inhibitor of telomerase on chondrosarcoma cells in vitro. METHODS:Telomerase activity, telomere lengths, growth kinetics and chemosensitivity were analyzed in chondrosarcoma cell lines treated with BIBR1532. RESULTS:BIBR1532 treatment resulted in telomerase inhibition, decrease of telomere length and reduction of growth capacity of telomerase positive chondrosarcoma cells. Although resistant to cisplatin, telomerase positive cells were sensitive to paclitaxel, which rapidly induced telomere erosion. CONCLUSION:Targeting of telomeres might represent a valid strategy for the (re-)sensitization of chemoresistant chondrosarcomas.

abstract::CD147 is highly expressed on many tumor cells; its role for tumor invasiveness and metastasis has been deduced from its capacity to induce MMPs, i.e., MMP-1, -2, -3, and -9. However, in the murine B16 melanoma model, MMP-2/-9 expression occurs independent of CD147. To scrutinize the impact of CD147 on metastasis forma...
