As shown in Figure 7A, knocking down PBX3 significantly slowed down the growth of the xenografted tumors formed by HCC-LM3 cells, whereas HMGCR overexpression partially reduced this suppressive effect, thus partially restoring the tumor growth rate as well as the size and weight of the tumors (Figure 7B,C). Here, PBX3 is linked to hepatocellular carcinoma.
