Molecular Biology of Long Non-coding RNAs

This second edition shows how long non-coding RNAs (lnc)RNAs have emerged as a new paradigm in epigenetic regulation of the genome. Thousands of lncRNAs have been identified and observed in a wide range of organisms. Unlike mRNA, lncRNA have no protein-co

Preface

Since the dawn of molecular biology it was accepted that most, if not all, biological processes are controlled by proteins. With a few exceptions, the vast majority of the scientific literature from the 1960s to the 2000s focused on proteins and their roles in development and disease. Although as early as the 1960s it was clear that living cells produce RNA molecules that are never translated into proteins (e.g., ribosomal RNAs, transfer RNAs), the prevailing dogma during that time was that RNA only serves as messengers for protein translation (mRNAs) or as constituents of protein building machinery (rRNAs, tRNAs). In the late 1980s and early 1990s, with the discovery of H19 and XIST, two genes that code for long non-coding RNAs with no protein-coding capacity, it was the first emerging evidence that RNAs could serve regulatory roles. Over three decades after the discoveries of H19 and XIST, we now know that the human genome is transcribed into both coding and non-coding transcripts, with current estimates of over 20,000 long non-coding RNAs. These coding and non-coding transcripts represent the first level of functional biology downstream of DNA and that, both directly and indirectly, yield the astounding complexity of molecula
