RESUMEN
LncRNAs( long noncoding RNAs ) can be defined as RNA transcrips longer than 200nt without protein coding capacity , which play vital roles in various aspects of gene expression regulation.Recent investigations showed aberrant expression of many lncRNAs in primary liver cancer , indicating their important roles in tumorigenesis and development of liver cancer.This review focuses on the biological functions of lncRNAs and their involvements in primary liver cancer.
