Small-molecule regulation of zebrafish gene expression

Hanife Esengil , Vicky Chang , John K Mich & James K Chen

The zebrafish has emerged as a versatile model organism for biomedical research, yet its potential has been limited by a lack of conditional reverse-genetic tools. Here we report a chemically inducible gene expression technology that has orthogonality to vertebrate signaling processes, high induction levels, and rapid kinetics.
