Body weight. Body weight was measured before irradiation (pre irrad.), and then every 4 months post-irradiation. There was no statistically significant difference between wild types and heterozygotes (p = 0.426), the development of body weight over the lifespan is shown for a wild-type males and b females as well as c heterozygous mutant (het mut) males and d females after different irradiation doses (color coded). Bars represent 10–20 mice, dependent on the survival (see Fig. 2). Error bars represent SEM
