AP-1 as a Regulator of MMP-13 in the Stromal Cell of Giant Cell Tumor of Bone

<table>The effect of siRNA knockdown on the level of MMP-13 activity in IL-1<i>β</i>-stimulated GCT cells. Filtered and concentrated conditioned media from siRNA silenced GCT stromal cells were analyzed using the MMP-13 activity kit as per optimization in our lab. Results of the ELISA activity assay are shown in triplicate with error bars. The MMP-13 activity levels were normalized to the amount of total protein for each condition.</table>
