Expression of AdipoR1 mRNA in the anterior and posterior pituitary. Comparison of adiponectin receptor 1 (AdipoR1) mRNA expression determined by quantitative real-time PCR in porcine anterior (A) and posterior (B) pituitary glands between days 2–3, 10–12, 14–16 and 17–19 of the oestrous cycle, and (C) between anterior and posterior pituitary glands on days 2–3, 10–12, 14–16 and 17–19 of the cycle. Results are means ± S.E.M. (n = 5). Bars with different superscripts are significantly different. Capital letters indicate p < 0.05; **p < 0.01; ***p < 0.001.
