This book evaluates trends arising in “-Omics” sciences in terms of their current and potential future application to therapeutic design and understanding of disease. Chapters consider the impact of pharmacogenomics and bioinformatics on drug development, as well as trends in genomics, as applied to understanding of neurodegenerative and lung disease, psychiatry and oncology.Following the genome studies released in early part of this century, the advent of the -Omics sciences (genomics and pharmacogenomics, proteomics, metabolomics, transcriptomics) has seen the expansion of a vast knowledgebase with utility in preventing and treating disease, and improving health for all. Bioinformatics and improved pharmacogenetic understanding forge a path for improved drug discovery and design methods accounting for differences in delivery and disposition across populations.
