Fig. 6From: Establishment of rat ankle post-traumatic osteoarthritis model induced by malleolus fractureEnhanced catabolism gene expression from ankle OA cartilage detected by qPCR. The qPCR results revealed that the both experimental groups had low levels of mRNA of Col2a1 (a) and Acan (b) and increased the level of mRNA of MMP-13 (c) compared with the contralateral control. Values are the mean ± SD, * = P < 0.05 versus controlsBack to article page
