This 2018 UK paper reviewed genomic imprinting:
“Since their discovery nearly 30 years ago, imprinted genes have been a paradigm for exploring the epigenetic control of gene expression. Moreover, their roles in early life growth and placentation are undisputed.
However, it is becoming increasingly clear that imprinted gene function has a wider role in maternal physiology during reproduction – both by modulating fetal and placental endocrine products that signal to alter maternal energy homeostasis, and by altering maternal energetic set points, thus producing downstream actions on nutrient provisioning.”
“Imprinted genes in the conceptus produce products that alter maternal resource allocation by:
- altering the transport capacity of the placenta;
- increasing fetal demand for resources by their action on the intrinsic growth rate; and
- signalling to the mother by the production of fetal/placental hormones that modify maternal metabolism.”
Other studies/reviews I’ve curated that covered genomic imprinting are:
- Epigenetic DNA methylation and demethylation with the developing fetus
- Genetic imprinting, sleep, and parent-offspring conflict
- A study of genetic imprinting and neurodevelopmental disorders
- Contending with epigenetic consequences of violence to women
