In summary, our results suggest that any one of MMP3 variants may not have a substantial effect on glioma risk, but a joint effect of MMP3 promoter polymorphisms may contribute to risk of gliomas, particularly for adult gliomas.
Single-dose treatment with Dex did not significantly change glioma volume in nude mice, but changed the expression of Ki67 and matrix metalloproteinase-3 in the tumour.
