We detected copy numbers and expression level of LINC01133 in HCC cell lines with different metastatic potentials and found that the LINC01133 copy numbers and expression level were greater in cell lines with high metastatic potential (MHCC97L, MHCC97H, and HCCLM3) than in cell lines with low metastatic potential (Hep3B, PLC/PRF/5, Huh7, and HepG2; Figures 2A and B). Here, LINC01133 is linked to hepatocellular carcinoma.
