|dc.description.abstract||Prostaglandins are integral mediators in reproductive processes but their exact role in uterine function is still not clear. In addition, ethical restraints have limited the availability of human tissue to investigate uterine prostanoid receptor populations. The aim of this thesis was to characterise the prostanoid receptors on the human and rat myometrium in order to evaluate the potential of the rat as an animal model of human uterine function and disease. For functional analysis of myometrial prostanoid receptors the immersion technique was utilised. LC-ESI-MS/MS was also used to measure the ex vivo myometrial release of prostanoid metabolites. The results show that both the rat and human uterus displays cyclical changes in uterine motility, with myogenicity greatest in the follicular and oestrus stages. The data also indicate that whilst the human uterus is responsive to EP3, EP2, TP, FP and IP receptor agonists, a functional population of only EP3, EP2 and FP receptors is present on the rat uterus, although the TP receptor appears to be upregulated at gestation and post-partum. The results also show that myometrial prostanoid release in the human uterus is cyclically regulated, with the greatest amount of prostaglandins being released during the late follicular stage. In conclusion, although similarities do exist with regard to the ovarian regulation of uterine motility in both the rat and human uterus, the differences in the apparent functional prostaglandin receptor populations between the two species suggest further work is required before the rat can be used as a model of human uterine function.||en_US|
