Perspectives on molecular assays for measuring mutation in humans and rodents.
The original idea for this article was to examine the new molecular techniques for detection of mutation directly at the DNA level in exposed individuals or their offspring and to assess their relative advantages and disadvantages for mutation monitoring in humans and rodents. However, an examination of the articles and a comparison of the technology indicated that our constant quests for methods improvement were leading to some loss of insight into the important health-related questions that should be guiding these endeavors. As a result, individual methods are not covered here in great technical detail. Instead, a few molecular methods are presented in a general overview, along with some of the biological issues related to the detection of induced mutations within individuals and populations. Some hypothetical scenarios are also presented because molecular approaches will continue to change rapidly, and we must continually adjust our thinking to combine the useful attributes of each current and future technical approach with the most appropriate biological questions.
