Relative mRNA abundance in endometrial IL18 mRNA expression from gilts (n = 4/day/status) on days 0, 5, 10, 12, 15, and 18 of the estrous cycle (open bars) and days 10, 12, 15 and 18 of pregnancy (black bars). Abundance of mRNA was calculated from the real-time PCR analysis as described in Methods and Materials. A significant day effect on relative mRNA units (mean ± SEM) was identified for endometrial IL18 (P < 0.05). Days without a common superscript represent a statistical difference.
