Introduction and objectives: Imprinted genes have been broadly related to prenatal growth regulation. PEG10 is a maternally imprinted gene involved in cellular proliferation that is mainly expressed in the placenta and in some adult tissues. In mice, mutations in this gene have been related to growth restriction of both the embryo and the placenta. Nevertheless, its role in postnatal growth has not yet been established. We aimed to study prospectively the rela...

Introduction: Imprinted genes are critical for placental function and normal fetal growth and development. Very little is known about the impact of maternal obesity on imprinted genes and their role in postnatal growth and metabolism.Objectives: 1) To identify umbilical cord DNA methylation sites (CpG) associated with gestational weight gain (GWG); 2) to identify which of these CpGs lie within imprinting control regions ...

Introduction and aims: MEST (Mesoderm-specific transcript), a candidate gene for Silver-Russell syndrome, is a paternally expressed imprinted gene that positively regulates foetal growth. MEST has also been shown to promote adipose tissue expansion in conditions of positive energy balance. In this context, our objective was to study the possible relationship between placental MEST gene expression and postnatal growth and obesity para...
