MYLK and hepatocellular carcinoma: To select HCC cell lines suitable for MYLK-AS1 overexpression and knockdown experiments, we used RT-qPCR analysis to examine the expression of MYLK-AS1 in four different HCC cell lines (HepG2, SMMC-7721, MHCC97-H, and BEL-7402) and one normal human hepatocyte cell line (LO2).
