MiRNA expression data from lean PCOS adipose vs BMI matched control women

ABSTRACT: Why ~70% of women with polycystic ovary syndrome (PCOS) have intrinsic insulin resistance (IR), above and beyond that associated with body mass, including dysfunctional glucose metabolism in adipose tissue (AT), remains a fundamental question. In these experiments, we sought to explore the role of miRNAs in the AT of PCOS and matched controls. Analysis determined that PCOS AT has a differentially expressed miRNA profile, including upregulated miR-93. We observed a significant association between HOMA-IR, and GLUT4 and miR-93 expression in human AT. Our results point to a novel mechanism for regulating insulin-stimulated glucose uptake via miR-93, and demonstrate upregulated miR-93 expression in PCOS, possibly accounting for the IR of the syndrome, and also in non-PCOS women with IR.
