Beskrivelse
The field of toxicogenomics is moving rapidly, so it is impossible at the timeofthiswritingtocompileaclassicmethodstextbook.Instead,wechose to identify experts in all aspects of this field and challenged them to write reviews, opinion pieces, and case studies. This book covers the main areas important to the study and use of toxicogenomics. Chapter 1 speaks to the convergenceofclassicapproachesalongsidetoxicogenomics.Chapter2deals withtheusefulnessoftoxicogenomicstoidentifythemechanismoftoxicity. Chapter3callsattentiontotheissuesthataffectthequalityoftoxicogenomics experiments, as well as the implications of using microarrays as diagnostic devices. The need for appropriate statistical approaches to genomic data is discussed in Chapter 4, and Chapters 5 and 6 describe the use of genomic datatobuildtoxicogenomicmodelsandprovideinsightsfromtheapproaches oftwocompanies.Theimportanttopicofstoringthedatageneratedinsuch experiments and the correct annotation that must accompany such data is considered in Chapter 7.
