Abstract:
Non-coding RNAs (ncRNAs) including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) have emerged as novel gene-regulators. The aim of this study was to determine the clinical relevancies of 2 lncRNAs (lncRNA-ATB and MEG3) and 2 miRNAs (miR-21 and miR-31) in hepatocellular carcinoma (HCC). We analyzed clinical specimens from 100 pairs of HCC and matched normal liver (NL) tissues. MiRNAs and lncRNAs expression levels were evaluated by quantitative real-time PCR. In addition, we determined the clinical significance of the ncRNAs expression in matching tissue and serum exosome samples from HCC patients. MiR-21 significantly increased in HCC (P & lt;0.01) compared to corresponding NL tissues. LncRNA-ATB was significantly up-regulated in HCC (P & lt;0.05); however, lncRNA-MEG3 was down-regulated in HCC (P & lt;0.05) tissues. In addition, expression of miR-21 and lncRNA-ATB was significantly associated with the tumor size and poor prognosis of HCC patients. More importantly, expression of serum exosomal lncRNA-ATB and miR-21 was more significantly associated with HCC progression and poor patients survival compared to its’ tissue expression. We conclude that non-coding RNAs (lncRNA-ATB and miR-21) expression has the potential to serve as biomarkers for prognosis and targeted therapy in HCC patients.
