Book Description
This book provides an overview of the role and function of regulatory RNAs that lack protein-coding potential in key reproductive tissues. This includes the role of small interfering RNAs (siRNAs), microRNAs (miRNAs), PIWI-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs) and long non-coding RNAs (lncRNAs). Through clear, detailed and comprehensive debate, international leading experts discuss the role these novel regulators in normal development of sexual dimorphisms, including the differentiation of ovaries and testes, the genital tract including prostate, epididymis and uterus, as well as mammary glands. In addition, particular attention is paid on their role in pathophysiological processes within the reproductive tract. The power of next generation sequencing has proved to be an invaluable tool to discover new non-coding RNAs. While the identification of non-coding RNA is relatively easy, analysing their function represents still a challenge today. In this book, authors present historical and conceptual background information, highlight the ways in which non-coding RNAs function is analysed and present their vision of the future research in their key research area.

Book Description
Over 98% of the human genome contains non-coding DNA sequences. For many years molecular biologists referred to this component of the genome as the “junk” DNA since it does not code for any “useful” protein product. Over the last years this notion changed significantly as scientists discovered that a large part of this DNA contains various genomic elements that have important roles in cell physiology. Genomic elements such as non-coding RNAs, transposons, splicing RNAs, DNA repeats and others were shown to play a significant role in regulating gene expression. In addition, all these elements were implicated to contribute in the pathogenesis or progression of various human diseases. In this book, the editor will attempt to describe all these genomic elements that constitute the junk DNA of the genome. For every genomic element, the physiologic role in the organism, its role in evolution and any possible involvement in human diseases will be discussed. Additionally, interaction between these elements in normal or pathologic condition will be discussed. Since a large amount of new knowledge is generated daily in regards to these genomic elements, this book will attempt to combine all the information in a single publication that can serve as a reference for future studies. The first part will discuss RNA elements such as microRNAs, long non-coding RNAs, piRNAs and splicing RNAs. The second part of the book will deal with transposons, retrotransposons and DNA transposons. Finally the third part of the book will discuss DNA elements that include DNA repeats, conserved non-coding sequences, distal genomic elements, introns, pseudogenes, CpG islands and telomeres. For miRNAs and CNVs a separate chapter will be dedicated to their role in human diseases since an extensive amount of information exists about these two elements.

Book Description
After transcription in the nucleus, RNA binding proteins (RBPs) recognize cis-regulatory RNA elements within pre-mRNA sequence to form mRNA-protein (mRNP) complexes. Similarly to DNA binding proteins such as transcription factors that regulate gene expression by binding to DNA elements in the promoters of genes, RBPs regulate the fate of target RNAs by interacting with specific sequences or RNA secondary structural features within the transcribed RNA molecule. The set of functional RNA elements recognized by RBPs within target RNAs and which control the temporal, functional and spatial dynamics of the target RNA define a putative “mRNP code”. These cis-regulatory RNA elements can be found in the 5’ and 3’ untranslated regions (UTRs), introns, and exons of all protein-coding genes. RNA elements in 5’ and 3’ UTRs are frequently involved in targeting RNA to specific cellular compartments, affecting 3’ end formation, controlling RNA stability and regulating mRNA translation. RNA elements in introns and exons are known to function as splicing enhancers or silencers during the splicing process from pre-mRNA to mature mRNA. This book provides case studies of RNA binding proteins that regulate aspects of RNA processing that are important for fundamental understanding of diseases and development. Chapters include systems-level perspectives, mechanistic insights into RNA processing and RNA Binding proteins in genetic variation, development and disease. The content focuses on systems biology and genomics of RNA Binding proteins and their relation to human diseases.

Book Description
The 'RNA world' hypothesis that proposed RNA molecules as the first form of genetic material was put forwarded in the late 1980s but got impetus only recently when high-throughput sequencing technologies began unearthing new types of non-coding RNA (ncRNA) transcripts in higher eukaryotes. Till then, research on ncRNAs were primarily confined to transfer RNAs and, ribosomal RNAs, which act as the messengers of the protein synthesis and allow translation of genetic information encoded by DNA into proteins. In recent years, the integration of high-throughput genomic technologies with molecular biology and omics sciences have revolutionized the fields of ncRNA research by identifying the hidden treasures of several new types of ncRNAs encoded in the genomes of several organisms and decrypting their versatile roles in gene expression and epigenetics. Among these, two small endogenous ncRNAs, namely microRNAs (miRNAs) and piwi-interacting RNAs (piRNAs) that drive argonaute (AGO) family of proteins namely Ago and Piwi respectively and silence the expression of genes have geared up molecular and disease biology research in recent years. Both miRNAs and piRNAs are expressed in higher eukaryotes, including human and act as cellular rheostats by regulating the expression of significant fraction of genes encoded in the genomes. The aberrant expressions of these small ncRNAs within the cells cause various abnormalities and diseases including cancer. Manipulating their aberrant expression or function can serve as potential novel diagnostic/prognostic biomarkers and bring in new therapeutic strategies for multiple human diseases. This can be further translated from bench-side to clinic for improving human health. This book captures the essence of the pioneering work of some of the world's leading researchers showcasing the scientific excitements surrounding the evolving regulatory roles of miRNAs and piRNAs highlighting their potential towards the diagnosis and therapeutics of various diseases. The book is geared towards scientists, students, and will particularly appeal to active investigators in RNA biology, molecular biology, cancer research as well as clinicians and will provide them a comprehensive view of recent discoveries and research progresses to utilize miRNAs, piRNAs and their interacting proteins, Ago and Piwi for diagnosis, prognosis and therapeutics of diseases. - Provides a unified cutting-edge resource for both miRNAs and piRNAs, two promising AGO-clade small ncRNAs, their functions and potential applications - Showcase high-throughput technologies and other approaches for discovery of these small ncRNAs and their targets - Unveils the diverse molecular mechanisms by which miRNAs and piRNAs regulate gene expression in animal cells - Showcase recent discoveries on involvement of Argonaute and Piwi proteins in different biological processes and diseases as well as their possible use in diagnosis - Report breakthroughs in the use of small ncRNAs for diagnosis and personalized therapy

Book Description
Repetitive DNA is ubiquitous in eukaryotic genomes, and, in many species, comprises the bulk of the genome. Repeats include transposable elements that can self-mobilize and disperse around the genome, and tandemly-repeated satellite DNAs that increase in copy number due to replication slippage and unequal crossing over. Despite their abundance, repetitive DNA is often ignored in genomic studies due to technical challenges in their identification, assembly, and quantification. New technologies and methods are now providing the unprecedented power to analyze repetitive DNAs across diverse taxa. Repetitive DNA is of particular interest because it can represent distinct modes of genome evolution. Some repetitive DNA forms essential genome structures, such as telomeres and centromeres, which are required for proper chromosome maintenance and segregation, whereas others form piRNA clusters that regulate transposable elements; thus, these elements are expected to evolve under purifying selection. In contrast, other repeats evolve selfishly and produce genetic conflicts with their host species that drive adaptive evolution of host defense systems. However, the majority of repeats likely accumulate in eukaryotes in the absence of selection due to mechanisms of transposition and unequal crossing over. Even these neutral repeats may indirectly influence genome evolution as they reach high abundance. In this Special Issue, the contributing authors explore these questions from a range of perspectives.
