title: miRNA mutation spectrum in eighteen hepatocellular carcinoma (HCC) cell lines with definite metastatic potentials and tropisms
design: In this study we investigate the miRNA expression profiles in 18 HCC cell lines with different metastatic potentials and organ-tropisms. Among them, HCC cell lines Huh7, Hep3B, SNU398, SMMC-7721£¬Bel-7402£¬HepG2£¬PLC-5 exhibit low metastasis abilities in nude mice model, while MHCC-97L, MHCC-97H, CSQT-1, CSQT-2, HCCLM3, LM1-S3, LM1-S4, LM1-S5, LM1-S11, LnM1-S11, LnM1-S13 exhibit high metastasis abilities in nude mice.
