microRNAs (miRNAs) are small non-coding RNAs that regulate various biological phenomena, such as development and homeostasis. The dysregulation of miRNA leads to disease progression, particularly of cancer. In Circulating MicroRNAs: Methods and Protocols, expert researchers in the field detail recent advances in the isolation, purification and analysis of circulating miRNAs from a variety of sources for research. The book is divided into three main topics. The first section involves the study of secretory miRNAs in cell-cell communication, and the second, the study of circulating miRNAs in body fluids. The last describes the novel techniques used to study circulating miRNAs. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Circulating MicroRNAs: Methods and Protocols seeks to aid scientists in dealing with the recent advances of RNAi technology from the bench to the bedside.

The discovery of microRNAs and its role as gene expression regulators in human carcinogenesis represents one of the most important scientific achievements of the last decade. More recently, other non-coding RNAs have been discovered and its implications in cancer are emerging as well, suggesting a broader than anticipated involvement of the non-coding genome in cancer. Moreover, completely new and unexpected functions for microRNAs are being revealed, leading to the identification of new anticancer molecular targets. This book represents a comprehensive guide on non-coding RNAs and cancer, spanning from its role as cancer biomarkers, to providing the most useful bioinformatic tools, to presenting some of the most relevant discoveries, which indicates how these fascinating molecules act as fine orchestrators of cancer biology.

MicroRNAs as the endogenous mediators of RNA interference have experienced an unprecedented career in recent years, highlighting their pathogenic, diagnostic and potential therapeutic relevance. Beside tissue microRNAs, they are also found in body fluids, most notably in blood. Significant differences of circulating microRNA levels have been found in various diseases, making them candidates for minimally invasive markers of disease, for example tumor malignancy. The book focuses on the potential diagnostic applicability of circulating microRNAs in various diseases and their potential biological significance.

As clinical management of inherited metabolic diseases (IMDs) has improved, more patients affected by these conditions are surviving into adulthood. This trend, coupled with the widespread recognition that IMDs can present differently and for the first time during adulthood, makes the need for a working knowledge of these diseases more important than ever. Inherited Metabolic Disease in Adults offers an authoritative clinical guide to the adult manifestations of these challenging and myriad conditions. These include both the classic pediatric-onset conditions and a number of new diseases that can manifest at any age. It is the first book to give a clear and concise overview of how this group of conditions affects adult patients, a that topic will become a growing imperative for physicians across primary and specialized care.

Short non-coding RNA molecules, microRNAs (miRNAs), post-transcriptionally regulate gene expression in living cells. In recent years, miRNAs have been found in a wide spectrum of mammalian body fluids including blood plasma, saliva, urine, milk, seminal plasma, tears and amniotic fluid as extracellular circulating nuclease-resistant entities. The changes in miRNA spectra observed in certain fluids correlated with various pathological conditions suggesting that extracellular miRNAs can serve as informative biomarkers for certain diseases including cancer. However, the mechanism of generation and a biological role of extracellular miRNAs remain unclear. The current theories regarding extracellular miRNA origin and function suggest that these miRNAs can be either non-specific ‘by-products’ of cellular activity and cell death or specifically released cell-cell signaling messengers. The goal of this Research Topic is to bring together up-to-date knowledge about the extracellular miRNA and its role in disease diagnostics and, possibly, inter-cellular communication.

This book presents an overview of the diagnostic performance of non- or semi-invasive tests for endometriosis in peripheral blood, endometrium, saliva, peritoneal fluid and urine. The value of existing and emerging systems biology technologies for biomarker development is addressed in several chapters on genetics, microarrays, proteomics and metabolomics. Although tests with high sensitivity and acceptable specificity have been developed, sometimes validated in independent populations and seem promising, more research is needed to translate these data into clinical benefit for patients and coordinate efforts internationally to standarize analysis, reports and operating procedures. The gold standard to diagnose endometriosis is currently through laparoscopic inspection with histological confirmation, a surgical procedure with rare but significant potential risks for the patients. A non-invasive test for endometriosis would be critical for the early detection of endometriosis of symptomatic women with pelvic pain and/or subfertility with normal ultrasound. This would include nearly all cases of minimal-mild endometriosis, some cases of moderate-severe endometriosis without a clearly visible ovarian endometrioma and cases with pelvic adhesions and/or other pelvic pathology, who might benefit from surgery to improve pelvic pain and/or subfertility. Such a test would also be useful in symptomatic women with ultrasound imaging suspicious for endometriosis, since it may be difficult to differentiate an ovarian endometrioma from other ovarian cysts and since the quality of ultrasound imaging is highly variable worldwide.

The world is faced with an epidemic of metabolic diseases such as obesity and type 2 diabetes. This is due to changes in dietary habits and the decrease in physical activity. Exercise is usually part of the prescription, the first line of defense, to prevent or treat metabolic disorders. However, we are still learning how and why exercise provides metabolic benefits in human health. This open access volume focuses on the cellular and molecular pathways that link exercise, muscle biology, hormones and metabolism. This will include novel “myokines” that might act as new therapeutic agents in the future.

MicroRNAs (miRNAs), which are a type of short non-coding RNA, are involved in number of processes, such as differentiation, development, inflammation, immune response, and cancer. miRNAs, which act as oncogenes or tumor suppressor genes, can control and regulate the translation and stability of target messenger RNA, contributing to cancer pathogenesis. Despite the progress that has been made in discovering the mechanisms of how miRNAs function in tumors, many questions and aspects of miRNA biology and processing still remain to be determined. This Special Issue, titled “MicroRNA in Solid Tumor and Hematological Diseases”, provides a panorama of the existing knowledge gaps and potential uses of microRNAs to predict clinical outcome or response to therapies and provides evidence to explain their role as biomarkers to modulate the biological pathways that are critical for cancer development and progression. It includes eleven peer-reviewed papers that cover the role of microRNAs in different tumor types and their potential applications in diagnosis and clinical approaches.
