The Bovine leukemia virus (BLV) is an oncogenic deltaretrovirus that induces enzootic bovine leukosis. Most of the infected bovines are asymptomatic, but after a long latency period, approximately 5% of them end up developing a leukemia/lymphoma. How the virus promotes the evolution of the disease is still not fully understood. Nevertheless, recently discovered antisense RNAs (AS1-S/L and AS2) are likely to have an important role in viral propagation and malignancy. The aim of work is to assess the involvement of antisense transcription in viral infectivity, replication and B cell homeostasis. Based on a reverse genetics approach, results show that a two base pair mutation in the promoter sequence affects negatively viral antisense transcripts levels in vitro, and that viral replication, in contrast to infectivity, requires expression of antisense RNAs in vivo.

MicroRNAs (miRNAs), endogenous noncoding regulatory mRNAs of around 22-nucleotides long, have rapidly emerged as one of the key governors of the gene expression regulatory program in cells of varying species, with ever-increasing implications in the control of the fundamental biological processes and in the pathogenesis of adult humans. The exciting findings in this field have inspired us with a premise and a promise that miRNAs will ultimately be taken to the heart for therapy of human disease. While miRNAs have been considered potential therapeutic targets for disease treatment, it remains obscured what strategies we can use to achieve the goal. In the past years, we have witnessed a rapid evolving of many creative, innovative, inventive strategies and methodologies pertinent to miRNA research and applications. These technologies have convincingly demonstrated their efficacy and reliability in producing gain-of-function or loss-of-function of miRNAs through targeting miRNA expression/biogenesis/function, providing new tools for elucidating miRNA functions and opening up a new avenue for the development of new agents targeting miRNAs for therapeutic aims. The present book provides comprehensive descriptions of these technologies and their applications to miRNA research and to new drug design for miRNA-related diseases. It starts with an overview of up-to-date knowledge of miRNA biology and the potential of miRNAs as therapeutic targets for human disease, followed by an introduction of the new concept of miRNA interference (miRNAi) and the perspectives of miRNAi technologies in general terms. In the following, each chapter introduces one of the miRNAi technologies with detailed descriptions of state-of-the-art design, procedures, principles and applications to basic research, R&D and clinical therapy.

Aberrant expression and function of microRNAs (miRNAs) in cancer have added a new layer of complexity to the understanding of development and progression of the disease state. It has been demonstrated that miRNAs play a momentous role in oncogenesis via regulating cell proliferation and apoptosis as oncogenes or tumour suppressors. Expression signatures of miRNAs offer exciting opportunities for crafting cutting edge strategies in the diagnosis, prognosis, and therapy of cancer. Since miRNAs can function as either oncogenes or tumor suppressor genes in the tortuous route of oncogenesis, the promise represented by using these small RNAs as therapeutic targets presents new perspectives to the landscape of cancer therapy by either inhibiting or augmenting their activity. This book devotes efforts to provide a broad framework for obtaining an in depth understanding of the state-of-the-art knowledge on abnormalities of miRNAs found to be associated with cancer pathogenesis and possible mechanisms underlying the substantial roles played by miRNAs in cancer development and progression. Also, it intends to pave the way for readers to gain novel insights into using miRNAs as cancer biomarkers and therapeutic platforms.
