Effect of chronic CORT exposure on the circadian rhythm parameters of feeding related genes in chicken hypothalamus. The circadian rhythms of feeding related gene mRNA expression in chicken pituitary. (A) NPY gene; (B) AGRP gene; (C) POMC gene; (D) CART gene. The relative mRNA levels of feeding related gene are normalized to PPIA. The data markers in the graphs indicate the feeding related gene mRNA expression levels, and the results are expressed as the mean ± SEM. The curves represent the 24-h period determined by cosinor analysis. n = 6 chickens per time point. Data from CT2 are double-plotted. R2 values represent the degree of fitting
