This fully revised book includes new and improved protocols to analyze toxicity at the DNA, RNA, and protein levels using genomic, epigenomic, transcriptomic, and proteomic approaches. Sections of the book address key subjects such as bioinformatics and biostatistics, toxicant-induced lung inflammation and tumors, analysis of protein and gene expression and silencing, gene promoter methylation, detection of chromosomal and genome-wide damage, analysis of DNA-adducts and surrogate gene mutations, detection and characterization of cancer gene mutation, and many other areas of study. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.  Comprehensive and up-to-date, Molecular Toxicology Protocols, Third Edition will prove to play an important role in generating a better understanding of the field of toxicology and its sub-disciplines.
