Figure 5From: 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 content of total caspase-1 protein (pg) in uterine flushings from gilts (n = 4/day/status) on days 10, 12, 15 and 18 of the estrous cycle (open bars) and pregnancy (black bars). Content of caspase-1 in the uterine luminal flushings of cyclic and pregnant gilts exhibited a day by status interaction (P < 0.05). Bars without a common superscript represent a statistical difference.Back to article page
