Pregnancy is accompanied by dramatic uterine adaptations to allow for development of a healthy placenta and to provide a safe environment in which to grow. This changes abruptly at the end of pregnancy when the uterus becomes activated and begins contracting to deliver the baby. Current research on the regulation of all these uterine changes focus primarily on the roles of proteins, hormones and prostaglandins. A well-known phospholipid which has recently been identified as an important factor within the reproductive field is sphingosine 1-phosphate (S1P). However, little is known about the role of S1P in uterine adaptations to pregnancy. The long-term objectives of my program of research are to define the role of S1P in pregnancy-induced events such as 1) implantation and control of trophoblast invasion; 2) uterine activation prior to labour and 3) stimulation of myometrial contractions.

怀孕伴随着子宫的剧烈适应，以促进健康胎盘的发育并提供安全的生长环境。这种情况在怀孕末期突然发生变化，此时子宫被激活并开始收缩以分娩婴儿。目前对所有这些子宫变化调节的研究主要集中在蛋白质、激素和前列腺素的作用上。 1-磷酸鞘氨醇 (S1P) 是一种著名的磷脂，最近被认为是生殖领域的重要因素。然而，人们对 S1P 在子宫适应妊娠过程中的作用知之甚少。我的研究计划的长期目标是确定 S1P 在妊娠诱发事件中的作用，例如 1) 滋养层侵袭的着床和控制； 2) 临产前激活子宫；3) 刺激子宫肌层收缩。
