Perinatal Research Group
- Group summary: The group's work covers a range of themes ranging from understanding disease aetiology through to the application of our findings in translational clinical trials.
What we do
Prediction/prevention of adverse pregnancy outcome
Much of our work in this area aims to integrate complementary research themes so as to integrate clinical, metabolomic, proteomic and genetic biomarkers in the pre-symptomatic detection of obstetric complications.
We cover two principal themes in oncology research. The bulk of our work revolves around the pathophysiology of endometrial cancer using genomic, transcriptomic, proteomic and lipidomic approaches. Much of our emphasis is placed on understanding the role of the tumour microenvironment in carcinogenesis. We are also interested in the role of microRNAs, predictive markers for response to novel targeted therapies, and the process of epithelial-mesenchymal transition in ovarian cancer.
Modelling immune networks
This area of work focuses on using Bayesian theory-based machine learning as a strategy to model the interactions of, and clarify the mechanisms controlling, inflammatory mediators.
Imaging of placental/cervical disorders
We use 3D reconstruction of various tissues particularly placenta, in order to appreciate the microstructural anomalies associated with the development of specific pathologies. We are particularly focusing on villous structure in the context of intrauterine growth restriction and pre-eclampsia, and the microarchitecture of the cervix. We are also developing the use of small-bore DT-MRI and lightsheet microscopy in these contexts.
Interaction between nutrition and pregnancy outcome
We work closely with the epidemiology unit in order to better understand the impact of nutrition on the incidence of pregnancy complications. Much of our research in this area has focussed on maternal caffeine and anti-oxidant intake.
Our work is collaborative and links in with other leading national and international groups. We particularly value the practical contribution of our research in driving our teaching and clinical practice in order to improve women’s healthcare.
