Long non-coding RNAs (lncRNAs) are a group of RNA transcripts that exceed 200 nt in length, yet lack significant open reading frames (ORFs) [1–4]. In contrast
Long non-coding RNAs （lncRNAs） are a group of RNA transcripts that exceed 200 nt in length, yet lack significant open reading frames （ORFs） [1-4]. In contrast to small non-coding RNAs （ncRNAs）, such as microRNAs （miR- NAs） [4-23], small interfering RNAs （siRNAs） [24-31] and transfer RNAs （tRNAs） [32-34], there are thousands of IncRNA genes discovered during the past three years in the human genome and most of their functions remain elusive. The long nucleotide chain of lncRNAs can either form a complex spatial structure and interact with protein factors, or provide a large segment for the concurrent binding of many molecules that collectively participate in genomic imprinting, X-chromosome silencing, chromosome modifi- cation, intranuclear transport, transcriptional activation and interference, thereby regulating cell growth, differentiation, development, senescence and death [35].
