Both an introduction and a fundamental reference, this book explores how to apply genomic, proteomic, and metabolomic technologies to surrogate tissue analysis. It reviews fundamental analytical issues and actual initial results generated using these technologies. The book covers transcriptional profiling (genomics), protein profiling (proteomics), methylation profiling (epigenomics), metabolite profiling (metabolomics) and additional biomarker identification methods that can be applied to surrogate tissues. This book is useful to researchers and scientists interested in applying novel methodologies for identifying biomarkers in the fields of pharmacology, toxicology, and medicine.
