AbstractGenetic manipulation techniques are widely used in mice to study the functions of genes. The most common strategy for assessing in vivo function involves making irreversible changes in the genome by homologous recombination. To complement this approach, a number of systems have been developed that allow specific and controlled expression of a gene. One of the more versatile and promising systems is based on the tetracycline (tet) responsive bacterial tetracycline repressor (TetR). In recent years, the tet system has proven to be a valuable method for understanding the function of genes involved in a number of physiological processes, including mouse models for human diseases such as cancer and neurological and pigment disorders. This review will highlight the power and elegance of the tet system by focusing on its utility in the study of two pigment cell-related biological problems, the pathogenesis of melanomas and melanocyte development in the embryo.
