Body weight kinetics of Grsf1^−/− mice and corresponding C57Bl/6J wildtype controls. From our colony of Grsf1^−/− mice and from wildtype control animals (C57Bl/6J) 10 male and 10 female individuals with similar body weights were selected. Of each genotype the males and the females were housed in separate cages. The animals were allowed to age for up to 50 weeks with standard chow diet and water at libitum. Each week the individual body weights were measured once and the animals were inspected for phenotypic peculiarities. The body weight of each individual at the beginning of the experiment was set 100% and the relative bodyweight increase was quantified. A Female individuals, B Male individuals
