Abstract: AIM: To observe the effect of alendronate sodium (fosamax) on inhibition of invasion and migration of human chondrosarcoma cells. METHODS: Human chondrosarcoma cells were treated with 100 μmol/L of alendronate sodium. Matrix metalloproteinase (MMP-2) activity and invasion ability were observed by gelatin zymography and stromal invasion experiment, respectively. RESULTS: The data showed, the degree of inhibition in migration and invasion of chondrosarcoma cells closely was related to the alendronate sodium treated dose and time. In addition, detected with gelatin zymography and RT-PCR, alendronate sodium significantly reduced mRNA levels and enzyme matrix metalloproteinase activity in a concentration related manner. CONCLUSION: Alendronate sodium can reduce the matrix metallo- proteinases in transcription and translation level, and inhibit the invasion of chondrosarcoma cells. Therefore, alendronate sodium, an adjuvant therapy agent, can be used as a systemic treatment for chondrosarcoma and other malignant tumour.
