Research issues

PCOS is the commonest cause of anovulatory infertility in women. Women may also suffer from cancer of the womb, obesity, cardiovascular disease, diabetes and hirsutism. It affects 5-18% of women in the population and the current estimated annual costs of diagnosing and treating infertility secondary to PCOS in the UK range from £16 million to £22 million.

The health economic impact of PCOS in the USA has been estimated as ranging from $93 million to $1.77 billion. Although significant progress has been made in our understanding of PCOS, there are still challenges in unravelling its complexity. The diagnosis of PCOS is based on a combination of clinical, ultrasound and biochemical features, none of which on its own is diagnostic.

A single unifying mechanism has yet to be found which explains PCOS, and accurate prediction of response to treatment for obesity, infertility and hirsutism (which women with PCOS often present to the clinician with) remains a challenge.

New experimental approaches are therefore required in women with PCOS to help address some of these scientific and clinical challenges. Recent advances in the area of molecular systems biology which allow high throughput investigations of genetic, protein and metabolite expression in human tissue however, offer significant promise in the identification of new pathways and targets for previously incompletely understood diseases such as PCOS.

What we are doing about...

1. Diagnosis and risk stratification of PCOS

Our research group is undertaking clinical studies to identify new genomic, proteomic and metabolomic biomarkers and pathways to improve the diagnosis and risk stratification of women with PCOS.

2. Investigating the molecular links between PCOS and endometrial (womb) cancer including the insulin pathway and metabolomics

Studies are ongoing investigating the insulin pathway, fatty acid metabolism and meabolomics biomarkers in women with PCOS and endometrial cancer.

Current projects

  1. Nasir Shafiee-PhD, Nottingham. (University of Malaysia Scholarship). Investigating the molecular links between PCOS and endometrial cancer.
  2. Gulshafana Khan- MD, Nottingham Biochemical and ultrasound studies into the aetiology and characterization of Polycystic Ovary Syndrome.
 

Outcomes

  • Novel biomarkers have been identified and are being validated.
  • Patents have also been filed.
  • A novel database of the identities, function and pathways of the in-house and external proteomic biomarkers identified in the literature in women with PCOS has been developed to provide a framework for scientists globally to facilitate a systems approach to profiling future biomarkers in PCOS.
