To explore this idea, we bred the MMTV-PyMT transgenic mouse strain (which spontaneously develops breast tumours) 26 with an uninduced Gclc f/f Rosa26 creERT2 mouse 27 in which the rate-limiting step in GSH synthesis, the glutamatecysteine ligase catalytic subunit (GCLC), can be knocked out throughout the body after induction with tamoxifen
