Volume 2 collects all the practical details required for efficient translation of discovered targets into real pharmaceutical drugs. Specific targets in cancers and autoimmunity are described and the potential of using siRNAs, antisense oligonucleotides and RNA aptamers in patients is reviewed. This volume explores the tremendous impact of the application of genotyping and gene expression profiling on the future of healthcare, and presents cutting-edge protocols to aid in bringing agents against specific targets closer to application in the clinic.
