Zheng F, Liao Y-J, Cai M-Y, et al. The putative tumour suppressor microRNA-124 modulates hepatocellular carcinoma cell aggressiveness by repressing ROCK2 and EZH2. Gut 2012;61:278–89. doi:10.1136/gut.2011.239145

The representative image of siEZH2 cells in Figure 4A, and the representative images of miR-124, miR-124-ROCK2 and miR-control cells in Figure S5 were incorrect.

The correct Figure 6 and Figure S5 are shown below. The figure legend remains the same.
