Northern blot analysis of pig AKR1C1 mRNA expression in the ovary during the estrous cycle and pregnancy. A. Ovarian tissues were obtained by laparotomy under general anesthesia on days 5, 10, and 15 of the estrous cycle. B. Ovaries were collected by the same method on days 0, 30, and 60 of pregnancy, and before parturition. Blots shown are the results of a representative experiment; graphs show the average ± SEM of 3 independent experiments. P-part: before parturition.
