CCL24 and hepatocellular carcinoma: qRT-PCR and ELISA revealed that the mRNA and protein levels of CCL24 were significantly higher in highly metastatic HCC cell lines (MHCC-97H and HCCLM3) compared to less metastatic HCC cell lines (Hep3B, HepG2, SMMC-7721, and Huh7) and a normal liver cell line (L02) (Huh7 vs. HCCLM3: p=0.0074; p=0.0008; Figure 1E).
