Trosolwg ymchwil

Mae fy ymchwil yn ceisio mynd i'r afael ag un o'r cwestiynau mwyaf heriol a sylfaenol bwysig ym maes iechyd pobl, sef sut i fanteisio i'r eithaf ar y siawns o feichiogrwydd iach a llwyddiannus. Mae gofal sy'n gysylltiedig â beichiogrwydd yn costio tua £5.8 biliwn y flwyddyn i'r GIG, ond dim ond 2.4% o'r holl gyllid ymchwil iechyd uniongyrchol, nad yw'n ddiwydiant sy'n cael ei wario ar ymchwil sy'n gysylltiedig â beichiogrwydd (adroddiad RAND, 2020). Mae hyn yn nodi mai ymchwil beichiogrwydd yw un o'r meysydd ymchwil sydd wedi'u tanariannu fwyaf yn y DU. Ac eto, dyma lle mae iechyd pobl yn dechrau a lle gallwn wneud y newidiadau mwyaf effeithiol i wella iechyd nid yn unig y fam ond hefyd ar gyfer cenedlaethau'r dyfodol. Mae fy ngrwpiau ymchwil yn defnyddio data carfan ddynol (The Grown in Wales Study) a systemau arbrofol i archwilio sut mae adfyd cynenedigol, yr amcangyfrifir ei fod yn effeithio ar fwy na hanner holl feichiogrwydd y DU, yn peryglu twf ffetws ac iechyd meddwl mamol, ac yn rhaglennu rhai o'r clefydau mwyaf cyffredin a threiddiol sy'n effeithio ar boblogaethau dynol.

Summary

The principal interest of my laboratory lies in understanding how epigenetic marks direct mammalian development with a particular focus on in utero processes, and how exposure during critically sensitive windows in development can alter outcomes for both mother and child.

Genomic Imprinting

Genomic imprinting is an epigenetic system, first initiated in the germ line, that directs the allele-specific expression of a small set of developmentally important genes (Figure 1). Imprinted genes function within a myriad of networks to regulate fetal growth, placental development, metabolism and behaviour. The aberrant expression of imprinted genes has been reported in relation to low birth weight, placental dysfunction, metabolic and psychiatric diseases. A goal of our research is to further understand the dosage-related function of imprinted genes in development and disease. We are also investigating factors and lifestyles which may influence the expression of imprinted genes early in life resulting in pregnancy complications, mood disorders and poorer behavioural outcomes for children both in the short term and across the life course.

The placenta

We have demonstrated that certain imprinted genes regulate the size of the endocrine compartment of the placenta and consequently modulate the production of placental hormones (Figure 2). During pregnancy placental hormones flood the maternal circulation to induce the physiological changes required for a successful pregnancy. Placental hormones ensure nutrient availability to ensure appropriate fetal growth. Placental hormones also prime the maternal brain in preparation for mothering the newborn infant. Funded by BBSRC, we are using unique experimental models based on the genetically modified expression of imprinted genes to experimentally show that imprinted genes influence fetal growth and maternal caregiving through the regulation of placental endocrine lineages (Figure 3).

Environmental programming

Imprinted genes are regulated by epigenetic marks that can respond to environmental factors. In addition to exploring the consequences of aberrant imprinted gene expression, funded by BBSRC we are investigating whether specific maternal diets or conditions can influence gene expression in the placenta causing placental endocrine dysfunction (Figure 4) and in the fetus directly influencing development, both of which may be linked to the poorer outcomes for children.

Lifelong health

It is well known that prenatal adversity is associated with poorer outcomes for children including behavioural difficulties and metabolic disorders. Funded by BBSRC and Wellcome Trust, we are exploring the consequences of placental endocrine dysfunction on offspring outcomes focusing on offspring behaviour (Figure 4).

Clinical engagement

The imprinted genes we are studying regulate placental development, fetal growth and maternal adaptations to pregnancy via the regulation of placental signalling. The aberrant expression of imprinted genes is common in a number of human disorders of pregnancy including low birth weight, gestational diabetes and preeclampsia. Our recent work suggests that aberrant imprinting may also have relevance to maternal mood disorders programmed by placental dysfunction. Funded by MRC, we initiated “The Grown in Wales” Study (Figure 5) to collect of data and biological samples including placenta from women delivering locally at University Hospital Wales to integrate the knowledge gained from our experimental models with studies on human samples. We are also assessing the development and behaviour of the children from this study in “The Grown in Wales Infant Study” funded by The Waterloo Foundation. Our work will promote the optimal interpretation of clinical data with a longer-term goal of improving diagnostic performance and the identification of possible therapeutic targets for treatment.
