Long Noncoding RNAs: Potential Mediators of Liver Cancer Metastasis.

Liver cancer (LC) is the most common high-mortality malignancy, due to its aggressive nature, heterogeneity, and metastasis. Recent studies have recognized long noncoding RNAs (lncRNAs) as mediators of LC pathogenesis and metastasis. This review describes the role of lncRNAs in molecular mechanisms of tumorigenicity, metastasis, stem-cell maintenance, drug resistance, and tumor immunity. We present recent updates on therapeutic targeting of lncRNAs in LC as well as lncRNA's potential for LC diagnosis. Overall, we provide a new perspective on the role of lncRNAs for LC treatment and diagnosis.
