We found that the mRNA expression levels of AC099850.3 and AC092171.2 was significantly higher in HCC cells and tissues, while the AL158206.1 and CASC19 is upregulated in part HCC cell lines, and no significant difference was observed in CASC19 and AL158206.1 expression between HCC tissues and para-cancerous tissues. This evidence concerns the gene CASC19 and hepatocellular carcinoma.
