Abstract
In recent years, with the intensive use of large-scale sequencing replacing microarrays for the detection of gene expression in several organisms, it has become clear that, in all eukaryotes studied so far, thousands of long (> 200 nucleotides) non-protein coding RNAs (lncRNAs) represent a very diverse and very tissue-specific class of RNAs in a cell. Despite this, only about four dozen l…
