Figure 3From: Endometrial caspase 1 and interleukin-18 expression during the estrous cycle and peri-implantation period of porcine pregnancy and response to early exogenous estrogen administrationRelative mRNA adundance in endometrial caspase-1 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 × status interaction on relative mRNA units (mean ± SEM) was identified for endometrial caspase-1 (P < 0.05). Bars without a common superscript represent a statistical difference.Back to article page
