Pancreatic ribonuclease, the focus of highly productive scientific research for more than half a century and the only enzyme to be the basis of four Nobel prizes, has recently undergone a resurgence in popularity for the recognition of an extended ribonuclease superfamily with functions ranging from tumour growth and inhibition to self-recognition and neurotoxicity. This volume highlights the functional diversity of ribonucleases and reveals the emerging research opportunities provided by these enzymes.* Never before has discussion of the entire family of ribonucleases and related

The Many Faces of RNA is the subject for the eighth SmithKline Beecham Pharmaceuticals Research Symposia. It highlights a rapidly developing area of scientific investigation. The style and format are deliberately designed to promote in-depth presentations and discussions and to facilitate the forging of collaborations between academic and industrial partners.This symposium focuses on several of the many fundamental, advancing strategies for exploring RNA and its functions. It emphasizes the interplay between biology, chemistry, genomics, and molecular biology which is leading to exc

Mitochondria play an increasingly central role in the context of cellular physiology. These organelles possess their own genome (mtDNA), which is functionally coordinated with the nuclear genome. Mitochondrial gene expression is mediated by molecular processes (replication, transcription, translation, and assembly of respiratory chain complexes) that all take place within the mitochondria. Several aspects of mtDNA expression have already been well characterized, but many more either are under debate or have yet to be discovered. Understanding the molecular processes occurring in mitochondria also has clinical relevance. Dysfunctions affecting these important metabolic ‘hubs’ are associated with a whole range of severe disorders, known as mitochondrial diseases. In recent years, significant progress has been made to understand the pathogenic mechanisms underlying mitochondrial dysfunction; however, to date, mitochondrial diseases are complex genetic disorders without any effective therapy. Current therapeutic strategies and clinical trials are aimed at mitigating clinical manifestations and slowing the disease progression to improve the quality of life of patients. The goal of the Special Issue ‘Mitochondria: from Physiology to Pathology’ published in Life (ISSN: 2075-1729) was to collect research and review articles covering the physiological and pathological aspects related to mtDNA maintenance and gene expression, mitochondrial biogenesis, protein import, organelle metabolism, and quality control.

Ribonucleases are a ubiquitous and functionally diverse group of enzymes that have a common ability to cleave RNA. Either through scission of internal phosphodiesters, or removal of nucleotides from RNA 5’ or 3’ ends, ribonucleases perform essential roles in gene expression and regulation, genome replication and maintenance, host defense, stress response, and viral strategies of infection. Ribonucleases have also served as highly informative models to understand virtually every aspect of biomolecular structure and function. The fifteen chapters in this volume are written by recognized researchers in the field, and provide in-depth analyses of the major ribonuclease families. Particular focus is given to the relation of ribonuclease structure and mechanism to biological function, as well as ribonuclease dysfunction in certain disease states. Other topics include the evolutionary genetics and functional diversification of ribonucleases, engineered ribonucleases as anti-cancer agents, the mechanisms of action of artificial ribonucleases, and ribonucleases as models to understand protein folding and stability. This volume should serve as an essential reference for a broad range of researchers and educators with interests in RNA metabolism, enzymology, and gene regulation.
