- Overview
-
Development from conception to birth is the result of a complex interplay of signals from mother and fetus. The placenta plays a key role in interpreting these signals and regulating fetal growth. Many complications of pregnancy, including miscarriage, maternal preeclampsia, preterm birth, fetal growth restriction and birth defects can result from abnormalities affecting the placenta. Some goals of our research include:
Understanding how genetic and epigenetic changes arise in development;
Identifying genetic and epigenetic changes in the placenta in association with pregnancy complication; and
Developing DNA and miRNA based clinical tools

Genomics and epigenomics of development
The maternal environment (stress, inflammation, diet, etc.) can lead to both short- and long-term effects on fetal development and susceptibility to disease in the newborn. For example low maternal folate is associated with neural tube defects, but also may have more variety of other effects on health programming in the offspring. The placenta may be a source of information about the health of the fetus/newborn. We are using genomic approaches to understand causes of birth defects and inflammatory conditions of the newborn and to use these to better predict newborn health at birth.Placental complications of pregnancy
Every year in Canada, thousands of pregnancies experience obstetrical complications, including preeclampsia, low birth weight, and pre-term delivery. These conditions put the newborn baby at higher risk of adverse health consequences, the mosty immediate of which is an increased risk of early infection. To improve the health of babies and children we want to better understand the causes of such conditions and provide tools to improve early screening of pregnant women and newborn babies to identify those most at risk. We are currently investigating the role of genetic and epigenetic changes in such outcomes. In particular, we are utilizing genomic approaches to study global alterations in DNA methylation and gene expression, and to identify DNA and non-coding RNAs that can be exchanged between mother, placenta and fetus. This research will serve as an important step to improve diagnosis and identify potential treatments that may assist in the management of such pregnancies.The genetics of sex differences related to perinatal health
Our goal is to understand why pregnancies with a female fetus are less vulnerable to infection, preterm birth and other adverse outcomes, than those with a male fetus. At the most basic level, the only difference between males and females is that males generally have one X and one Y chromosome, while females have two X chromosomes. In females, most of the genes on of the two X's in are typically turned off in each cell to equalize gene dosage between the sexes; However, this process appears to be relatively sloppy in the placenta, the organ upon which the fetus depends on for normal growth and development. We expect that sex-differences in placental biology likely drive a wide-range of downstream effects on fetal health including susceptibility to infection and preterm birth. Our goal is to understand the basis for these sex-differences in the placenta and how this might account for the increased risks to male fetuses. We also hope to bring attention to some of the fundamental biological differences between the sexes that influence how different early in utero exposures might affect infant development.Honours & AwardsMedical Genetics Departmental Teaching Award 2005
