As our lab focused on HCC pathological investigation and previous studies have shown ZFAS1 can exert their functions by lncRNAs in HCC (Dong et al., 2018; Luo et al., 2018), the expression level of ZFAS1 was further validated in 32 pairs of HCC/non-tumor tissue specimens using RT-qPCR. This evidence concerns the gene ZFAS1 and hepatocellular carcinoma.
