Regulating gene expression in transgenic animals.
Regardless of the field of application, the raison d'etre of transgenic animals is to study gene regulation and function. With increasing frequency, mammalian genes are being isolated with no concomitant knowledge of their function. The human genome mapping initiative will undoubtedly produce a cornucopia of such genes. While the merit of taking a transgenic route to study genes of unknown function is axiomatic, the choices of strategies for gene regulation in vivo may not be fully appreciated. This review will address two main points: first, the targeted and regulated expression of genes, and second, the structural and functional ablation of genes.
