Figure 6From: Binding characteristics of the ovine membrane progesterone receptor alpha and expression of the receptor during the estrous cycleComparison of mean relative expression of mRNA encoding mPRα versus mRNA encoding actin in ovine A) hypothalamus, B) non-luteal components of the ovary, C) pituitary, D) corpus luteum, or E) uterus throughout the estrous cycle (3 h and 24 h post estrus and days 4, 10, 15). Values on the y-axis (actin Ct/mPRα Ct) represent means ± SE of a minimum of three sheep. Significant differences (P < 0.05) between groups are indicated by different letters above the bars.Back to article page
