Over the past decade, genome-wide transcriptomic studies have shown that the mammalian genome is pervasively transcribed and produces many thousands of transcriptomes without bias from previous genome annotations. This finding, together with the discovery of a plethora of unexpected RNAs that have no obvious coding capacities, have challenged the traditional views that proteins are the main protagonists of cellular functions and that RNA is merely an intermediary between DNA sequence and its encoded protein. There are many different kinds of products that are generated by this pervasive transcription; this review focuses on long noncoding RNAs (lncRNAs) that have shown spatial and temporal specific patterns of expression and regulation in a wide variety of cells and tissues, adding significant complexity to the understanding of their biological roles. Recent research has shed new light onto the biological function significance of lncRNAs. Here, we review the rapidly advancing field of lncRNAs, describing their biological features and their roles in regulation of gene expression. Moreover, we highlight some recent advances in our understanding of ncRNA-mediated regulation of stem cell pluripotency, morphogenesis, and development, focusing mainly on the regulatory roles of lncRNAs. Finally, we consider the potential medical implications, and the potential use of lncRNAs in drug development and discovery and in the identification of molecular markers of diseases, including cancer.
