Research progress of long noncoding RNA in China.

RNA is essential for all kingdoms of life and exerts important functions beyond transferring genetic information from DNA to protein. With the advent of the state-of-the-art deep sequencing technology, a large portion of noncoding transcripts in eukaryotic genomes has been broadly identified. Among them, long noncoding RNAs (lncRNAs) have been emerged as a new class of RNA molecules that have regulatory potential in a variety of physiological and pathological processes. Here we summarize recent research progresses that have been made by scientists in China on lncRNAs, including their biogenesis, functional implication and the underlying mechanism of action at the current stage.
