Abstract

© 2015 Cold Spring Harbor Laboratory Press. Reversible regulatory mouse models have significantly contributed to our understanding of normal tissue and cancer biology, providing the opportunity to temporally control initiation, progression, and evolution of physiological and pathological events. The tamoxifen inducible system, one of the best-characterized "reversible switch" models, has a number of beneficial features. In this system, the hormone-binding domain of the mammalian estrogen receptor is used as a heterologous regulatory domain. Upon ligand binding, the receptor is released from its inhibitory complex and the fusion protein becomes functional. We summarize the advantages and drawbacks of the system, describe several mouse models that rely on it, and discuss potential improvements that could render it even more useful and versatile.
