Adipose Tissue Gene Expression Profiles in Women With Polycystic Ovary Syndrome (PCOS) Versus Controls

Adipose Tissue Gene Expression Profiles in Women With PCOS Versus Controls Matched for BMI

Adipose tissue is a central organ in mediating metabolic health. There is some evidence that women with polycystic ovary syndrome (PCOS) have a degree of adipose tissue dysfunction which may negatively affect their metabolic health. The aim of this study was to assess transcriptomic profiles of subcutaneous adipose tissue of women with PCOS in comparison with a control population matched on the basis of age and body mass index (BMI). A secondary aim was to then relate these gene expression profiles to the biochemical environment.
