This book provides a comprehensive overview of the development of therapeutic oligonucleotides for therapeutic applications, touching on a number of additional oligonucleotides including a number of small interfering RNAs currently in various phases of clinical development. Written by leading expert scientists from both academia and leading biotechnical companies, the authors provide a compelling update on current status of RNA interference with emphasis on fascinating topics including oligonucleotides: antisense oligonucleotides, ribozymes, siRNAs, decoy oligonucleotides and aptamers. This exceptional work will be a valid resource for researchers and students as well as academia, consultants and scientists.
