Corticosteroid receptor mRNA expression in the saccule of male and female Astatotilapia burtoni. (A) GR2 mRNA levels differed among all three female groups, and subordinate males had higher mRNA levels compared to dominant males. Inset: Brooding females had higher GR2 mRNA levels in the brain compared to both recovering and gravid animals. (B) GR1a mRNA levels were higher in recovering females compared to brooding and gravid individuals, and subordinate males had higher GR1a mRNA levels than dominant males. (C) Similar to GR1a, mRNA levels of GR1b were higher in recovering females compared to brooding and gravid individuals, and subordinate males had higher GR1b mRNA levels than dominant males. (D) MR mRNA levels were lower in gravid females compared to both brooding and recovering animals, and subordinate males had higher MR mRNA levels compared to dominant males. Inset: Brooding females had higher brain MR mRNA levels compared to both recovering and gravid animals. Data are plotted as relative mRNA levels (mean ± SE) referenced to the geometric mean of two housekeeping genes (18s and G3PDH). Bars with different letters represent significant differences (p < 0.05) and sample sizes are indicated within each bar on the bottom graphs.
