This volume focuses on the roles of long non-coding RNAs (lncRNAs) in contexts ranging from human cancers to cardiovascular disease and ageing. The role of lncRNAs in X-inactivation and those lncRNAs derived from pseudogenes, past retroelements integrated within the human genome, as well as the role these pseudogene-derived lncRNAs play in cancer development are discussed in detail. Further, th…
