ABSTRACT: We describe the lncRNA expression profiles of two HCC cell lines, one with high potential for metastasis to the lung (HCCLM3) and the other to lymph nodes (HCCLYM-H2). The HCCLM3(LM3) and HCCLM6 cell lines were derived from the same parental cell line MHCC-97H. LM3 metastasizes to the lung, while HCCLM6 can metastasize to multiple organs in a mouse model. By subcloning HCCLM6, we established the HCCLYM-H2(H2) cell line, which showed stable and high metastatic potential specific to the lymph nodes. In the present study, we compared the expression profiles of HCC cell lines with a similar genetic background but different potential for lung or lymph node metastasis. We found that expression signatures comprising lncRNAs and protein-coding mRNAs were significantly associated with organ-specific HCC metastasis. To further validate microarray data, we selected six lncRNAs (CR613944, BC058547, RP5-1014O16.1, NCRNA00173, lincRNA-CALCA, lincRNA-TSPAN8) and two mRNAs (TSPAN8, CALCB) in the two HCC cell lines using qRT-PCR. Data obtained from qRT-PCR and the microarray was consistent.
