ALAN effects on BMAL1 expression were comparable in different tissues. Correlation of expression patterns of BMAL1 in different tissues. Shown are log-transformed mRNA levels, separated by sampling time (day vs night) and ALAN treatments (blue colour gradient). Points represent individual birds. Lines and shaded areas depict model estimated means ± 95% confidence intervals. Panels show expression levels of BMAL1 in hypothalamus in relation to (A) hippocampus, (B) liver and (C) spleen, as well as spleen in relation to liver (D).
