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.

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.

This doctorate thesis provides an insight into the biology and dynamics of circulating microRNAs, demonstrating their potential to become crucial biomarkers for a better surveillance and prognosis of cancer. MicroRNAs (miRNAs) are small, single-stranded non-coding RNAs, 19-25 nt long, with a key role in the post-transcriptional regulation of gene expression, repressing the translation of target mRNAs through partial base-pair complementarity with their 3'-UTR. They can be released in the extracellular medium, being protected from RNases by association with various transporters and reach body fluids and circulation, participating in intercellular communication. Their remarkable stability and manageable diversity in circulation, as well as the fact that they derive from both malignant and normal cells make them very attractive biomarker candidates, potentially reflecting tumor state and dynamics. We have been focusing on ovarian (OvCa) and nasopharyngeal (NPC) carcinomas, attempting to elucidate the relation between plasma miRNAs and the prognosis of OvCa after first-line treatment, as well as to evaluate their use in the detection of early response of NPC tumors to treatment. Serous epithelial ovarian carcinoma is the most frequent ovarian and the most aggressive gynecologic malignancy. The absence of early symptoms and the insufficiency of modern means to accurately map residual disease and assess treatment outcome highlight the need for new diagnostic and prognostic biomarkers. Using sequential plasma samples from OvCa patients before and after first-line treatment, we studied a pre-selection of miRNAs, comparing them to samples from benign pelvic lesions and healthy women. MiR-200b exhibited a distinct higher concentration in malignant samples before treatment compared to both non-cancerous groups. Pre- and post-treatment assessment of miR-200b in parallel with the standard biomarker CA125 revealed distinct variations and a significant correlation of miR-200b variation with the progression-free survival (PFS) of the patient. We suggest that miR-200b could eventually be used as a supplementary biomarker for estimation of the remission upon treatment completion. Nasopharyngeal carcinoma (NPC) on the other hand is a tumor consistently associated to latent Epstein-Barr virus (EBV) infection of the malignant cells, presenting a unique geographical incidence pattern. The deep position of the tumor makes it tough to access surgically, with biomarkers assessing different therapeutic approaches being greatly needed. Studying a new oral form of the demethylating agent 5-azacytidine, proven to be promising for one third of NPC patients receiving it as a monodrug, we attempted to identify impact of the drug on the expression of viral miRNAs and proteins. Despite the latent viral infection, viral miRNAs are abundantly expressed, attracting interest in EBV-associated malignancies. Treating four in vivo developed NPC tumor models for two weeks, we observed clear response in two of them, in a dose-dependent manner. Protein analysis showed an induction of the immediate-early lytic protein BZLF1, solidifying previous evidence of partial activation of the viral lytic cycle by 5-azacytidine. MiRNA analysis confirmed robust expression of BART and absence of BHRF1 miRNAs at baseline status of NPC. Upon treatment, we observed an induction of BHRF1 miRNAs in both tumor and plasma of treated mice. This induction was successfully validated in a following one-week treatment and completed by a recorder de novo expression of the BHRF1 mRNA, transcribed within the BHRF1 miRNA loci. A weaker induction of BHRF1 miRNAs was also recorded after treatment with standard chemotherapeutic agents, suggesting a potential clinical utility of these miRNAs as circulating biomarkers for detection of early response to treatment. We are further working to confirm this induction by chemotherapy and extend our study to plasma samples derived from treated patients.

MicroRNAs (miRNAs), endogenous noncoding regulatory mRNAs of - nucleotides, have rapidly emerged as the central players in gene expression regulation. Owing to their ever-increasing implications in the control of various biological and pathological processes, miRNAs have now been considered novel biomarkers of various human diseases including, cancer, viral disease, cardiov- cular disorders, metabolic disturbances, etc. Particular expression pro?les have been associated with particular pathological states. Expression pro?ling of miR- NAs have therefore become extremely important not only for fundamentalists but also for clinicians. However, the methodologies used for detecting protein-coding mRNAs cannot be directly applied to miRNAs because of their small size. Over the past years, researchers have made great efforts to developing techniques suitable for miRNA detection and quanti?cation; a wide spectrum of creative and inno- tive techniques (more than 30 different methods) have been invented and validated. It has come to the time now to summarize these methods and present them in an orderly manner for better understanding and utilization of these methods to miRNA research and applications. In particular, the development of methods for quantifying circulating miRNAs opens up a fascinating opportunity for realizing miRNA as diagnostic and prognostic biomarkers of human disease. A book on this subject may help boosting up the passion of researchers to further improve the existing techniques and develop more new methods to ?t to new application needs. These considerations prompted us and urged us to undertake the work: writing a book focusing on miRNA expression detection methods.

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.
