Fig. 2. Fkbp5-genotype × ELA influence the unstimulated HPA axis activity in a sex-dependent manner.
Individual animal data is shown alongside with the mean (black diamond) ± 95% confidence intervals to indicate statistical differences among the subgroups. Selected results of the ANOVA at group level are indicated. All descriptive statistics, model summaries, and ANOVA results are provided in Supplementary Table 1–6. Diurnal rhythmicity of corticosterone plasma levels in female (a) and male (c) Fkbp5-humanised controls or ELA-exposed mice. A different scale for males than females was used to make the pattern better visible. Significant diurnal rhythm was seen in CG-allele carrying female and male controls () and ELA-exposed mice (
), as well as in AT-allele carrying control (
) and ELA-exposed males (
). Morning corticosterone was higher in AT- vs. CG-allele carrying females (p = 0.03, $). Comparison of adrenal weights in females (b) and males (d). Female CG-allele carrying controls differ from most other subgroups (SNP × ELA × sex p = 0.04, #).
