In this study we used the cre-loxP recombinase system. All mice were genetically modified in as much as all mice had exon 4 of the IGF-I gene flanked by loxP sites. In the knockouts, Mx-Cre had also been introduced, which results in inactivation of the IGF-I gene specifically in the liver. RNA from ...
