Women with PCOS exhibit significantly higher basal levels of circulating miRNA-27b compared to BMI-matched healthy controls, independent of adipose tissue expression levels.
Women with PCOS have distinct molecular markers in their blood (specifically miRNA-27b) compared to healthy women of the same weight. This suggests PCOS involves specific metabolic dysregulation that is not solely explained by body fat levels.
GoodSupportsHIGH confidence
Basal expression of circulating miRNA-27b (c-miR-27b)... was 1.8-fold higher in women with compared to without PCOS (P = 0.006) despite no difference in gluteal or abdominal AT miR-27b expression.
Why this rating
Case-control study with matching for age and BMI, providing strong evidence for the association.
