enzyme overexpression in transgenic mice under control of a composite CMV-IE enhancer-chicken beta-actin promotor, 4 separate founder CAG/SpmS mice are analysed: enzyme expression in all tissues, mostly highly increased compared to the wild-type mice, overview | Homo sapiens |

additional information | enzyme overexpression in transgenic mice under control of a composite CMV-IE enhancer-chicken beta-actin promotor causes no deleterious effects, the mice show normal growth, fertility, and behaviour, the content of S-adenosylmethionine in transgenic mice is important for viability, overview | Homo sapiens |
