Figure 3From: MicroRNA-21 regulates breast cancer invasion partly by targeting tissue inhibitor of metalloproteinase 3 expressionTIMP3 protein expression correlates with microRNA-21 content in breast cancer cell lines in vitro. A, Western blot analyses of TIMP3 protein, performed as described in Methods. B, Correlation between miR-21expression and TIMP3 protein levels (Pearson correlation = -0.905; P < 0.05).Back to article page
