ABSTRACT
<p><b>OBJECTIVE</b>To identify the metastasis-related miRNAs in hepatocellular carcinoma (HCC) cell lines.</p><p><b>METHODS</b>A qRT-PCR method was established and optimized.</p><p><b>RESULTS</b>All candidate metastasis associated miRNAs except miR-124a were expressed in high metastasis cell line MHCC97H and low metastasis cell line MHCC97L, while some miRNAs were differentially expressed between liver cancer cell line (HepG2) and hepatic cell line (L02) (P less than 0.05), these miRNAs include miR-148b (1.96+/-0.51 vs 3.76+/-0.28), miR-9 (-4.38+/-0.86 vs -1.10+/-0.53), miR-30c (8.41+/-0.40 vs 6.82+/-0.29), miR-338 (3.14+/-0.29 vs -2.36+/-0.32), miR-34a (0.71+/-0.40 vs -2.95+/-0.26), Let-7g (-4.07+/-0.55 vs -6.98+/-0.56). miR-148b expression was about 4 times higher than miR-148a [5.46 (IQR 4.25-6.67) vs 1.29 (IQR 0.94-1.64)] in all cell line tested (Z=-5.097, P=3x10(-7)).</p><p><b>CONCLUSION</b>This study may help to understand the biological significance of miRNAs in HCC metastasis.</p>
