This volume presents new research on messenger RNA (mRNA), the crucial mediating template between DNA and protein synthesis. In five chapters and several expert commentaries, international scientists examine major proteins involved in this transcription process, e.g., p38, a key proinflammatory-signaling molecule whose activity is being studied in order to develop inhibitors to treat rheumatoid arthritis and other chronic inflammatory diseases. Experimental methods and findings are presented relating to the role of mRNA in other clinical applications and to its basic role in gene expression. Illustrations include mRNA pathways for specific genes, mRNA encoding of proteins, and phylogenetic analysis diagrams. The editor's credentials are not given.
