A number of pathologies of pregnancy, including up to 50% of miscarriages, preeclampsia (hypertension and proteinuria in pregnancy), intrauterine growth restriction (IUGR), preterm labour, unexplained stillbirth and placental abruption are characterised by impaired cytotrophoblast invasion and inadequate response of the uterine spiral arteries to undergo physiological transformation. Together these conditions affect more than one quarter of pregnant women in developed societies. Our laboratory takes a "bench to bedside" approach to discovery and solving clinical problems in pregnancy that have their origins in placental development and maternal adaptation to pregnancy. We undertake basic cellular and molecular experiments to elucidate mechanisms that govern normal and abnormal placental development. We also have a strong focus on identifying genetic, nutritional, lifestyle and clinical factors that associate with pregnancy outcome in the SCOPE and PAPO pregnancy cohorts. Current projects include single nucleotide polymorphisms in mother, father, baby trios in prediction of pregnancy complications, the role of vitamin D in placentation (in human and knockout mice), the role of hypoxia in early placental differentiation, and sex differences in the human placental transcriptome.
1. Diagnosing risk for pregnancy complications and applying results of basic research to clinical problems
We were funded by Government of South Australia to develop predictive tests for couples' risks for complications of late pregnancy, specifically preeclampsia, IUGR and pre-term birth. This is the Adelaide arm of the SCOPE (SCreening fOr Pregnancy Endpoints) project. SCOPE is an international consortium of clinicians and scientists who by the end of 2011 had assembled a biobank and detailed clinical and lifestyle database for nearly 6,000 women pregnant for the first time and their partners. Recruiting has ceased in all SCOPE centres. In Adelaide we are undertaking a targeted gene approach and aim to identify genes that determine a couple's risk prior to the development of symptoms. These genes have already been shown to be important in the control of placental development. We have a particular interest in how the father imparts risk for pregnancy complications in the mother and baby. We have recently developed algorithms to predict risk in early pregnancy for subsequent preeclampsia, preterm birth, IUGR and gestational diabetes using combinations of genetic, clinical and lifestyle factors.
We have another cohort Predicting Adverse Pregnancy Outcomes (PAPO) in whom women suffer recurrent pregnancy complications but primarily recurrent spontaneous miscarriage (RSM). It appears that RSM is in the continuum of pregnancy complications associated with poor placentation. We aim to elucidate molecular mediators in RSM and identify potential therapeutic targets for subsequent development and testing.
We will begin recruiting women to our new cohort study, Screening Tests to Predict poor Outcomes in Pregnancy (STOP Study) in early 2015. We aim to validate our early pregnancy screening tools based on our predictive algorithms for risk of pregnancy complications. We will utilise our new software designed to provide an individualised probability of risk for each couple in the STOP Study. We will also continue to collect important clinical and lifestyle data about each pregnancy and health of both mother and child.
2. The role of Vitamin D in the placenta and pregnancy success
Recently, vitamin D has emerged as a micronutrient critical to optimal pregnancy outcome. In women, vitamin D deficiency has been associated with complications of pregnancy including preeclampsia, intrauterine growth restriction, gestational diabetes, preterm birth and a greater need for caesarean section. Although our understanding of the specific functions of vitamin D in pregnancy is scant, it seems likely that vitamin D deficiency may play a role in complicated pregnancies because robust regulation of vitamin D activation and degradation occurs in the placenta. The placenta contains enzymes responsible for localized vitamin D activation and degradation, as well as the vitamin D receptor, which is responsible for mediating vitamin D-dependent gene expression. In addition, vitamin D is known to interact with the IGFs and with members of the renin angiotensin system that are also important in pregnancy success (see below).
Perhaps the best known function of vitamin D is in the maintenance of calcium balance. Indeed, calcium supplementation in women with low dietary calcium has been shown to prevent preeclampsia. However, little is known of the mechanisms by which vitamin D and calcium act in the placenta and in maternal adaptation to pregnancy. Vitamin D is likely to interact with a number of other systems in a calcium-dependent and -independent manner, thus providing potential mechanisms for complications of pregnancy associated with vitamin D deficiency. We will elucidate the molecular mechanisms by which vitamin D deficiency affects placentation and pregnancy outcome to provide the breakthrough in vitamin D and pregnancy research that has been elusive to date.
3. Epigenetic programming of placental and fetal development
IGF2 and its specific membrane receptor, IGF2R, are imprinted genes which means that only one copy of the gene is expressed, the other having been silenced by DNA methylation. IGF2 is expressed from the paternal allele, while IGF2R is expressed only from the maternal allele in most species. We have recently shown that both genes are important in controlling placental invasion. A number of factors can alter the methylation status of imprinted genes including maternal nutrition, ex vivo embryo culture and cloning. Previously, we examined the effect of cloning, ex vivo embryo culture and periconceptional undernutrition on placental development and methylation of imprinted genes in the sheep. Currently we are determining whether imprinting may play a role in human pregnancy complications and particularly in placental development. We have recently quantified allele specific expression of IGF2, IGF2R and H19 across gestation in human placenta. Of most intrerest is our finding that H19 imprinting in placenta is plastic across first trimester. Biallelic expression of H19 has previously been shown in term placenta from preeclamptic pregnancies and was associated with hypertensive crisis. Could it be that aberrant H19 imprinting in first trimester is an important epigenetic link to preeclampsia? We are also currently exploring patterns of DNA methylation in non-imprinted genes and their relationship with placental development and pregnancy success.
4. Placental invasion and the blood supply to the placenta
A current focus in basic research in our group is on the development of the placenta and the vessels which supply it. A number of pathologies of pregnancy, including up to 50% of miscarriages, preeclampsia, intrauterine growth restriction (IUGR), preterm labour, unexplained stillbirth and placental abruption are characterised by an impaired cytotrophoblast invasion and inadequate response of the uterine spiral arteries to undergo physiological transformation. Together these conditions affect more than one quarter of pregnant women in developed societies. We aim to understand the factors that impair placental invasion and function and apply this understanding to determining which couples are at risk of developing serious pregnancy complications.
We are investigating the cellular and molecular mechanisms underlying the formation of vascular connections between the mother and fetus. The uterine arterioles which supply the placenta are invaded by placental cytotrophoblast cells and are dramatically remodelled to produce dilated compliant vessels which allow the 12 fold increase in blood flow to the uterus which is essential for normal placental, and hence fetal, growth. However, the mechanisms by which physiological transformation of these vessels occurs are poorly understood. We are currently delineating the cellular and molecular interactions between maternal decidua and fetal trophoblast during the normal transformation of the arterioles which supply the placenta using both human placental tissue and that in mice.
5. The role of the renin angiotensin system in the placenta and pregnancy outcome
The renin angiotensin system is best known for its actions in regulating blood pressure and water/salt homeostasis. During pregnancy this system is an important mediator of the dramatic changes in plasma volume and peripheral resistance. Pregnant women are less sensitive to the pressor effects of angiotensin II than non-pregnant women and are able to maintain blood pressure at normal levels in this highly haemodynamic state. However, the placenta also has its own local RAS which appears to be important for local angiogenesis and affects trophoblast invasion. We are identifying associations of this system with pregnancy complications and are undertaking in vitro studies to determine functional effects and interactions.
6. The Influence of Fetal Sex on the Placental Transcriptome
It has been known for sometime that there are sex differences in fetal growth, survival and long term health with boys at greater risk than girls for adverse outcomes. We have NHMRC funding to investigate sex differences in the placental transcriptome in normal pregnancy in order to elucidate the normal differences in placental function between females and males. We are utilising RNA sequencing, meta-analysis of microarray data and other high throughput genomics and bioinformatics approaches to understand placental sex differences.
