Expression profiles of circular RNA in granulosa cells from women with biochemical premature ovarian insufficiency.

To identify the expression profiles and potential functions of circular RNAs (circRNAs) in granulosa cells (GCs) from women with biochemical premature ovarian insufficiency (bPOI). CircRNAs microarray analysis was performed to GCs from 8 patients with bPOI and 8 control women, followed by qRT-PCR in 15 paired samples. CircRNA-miRNA networks and the prediction of their enriched signaling pathways were conducted by bioinformatics analysis. A total of 133 upregulated and 424 downregulated circRNAs was identified in women with bPOI. We constructed circRNA-miRNA networks and found that the most predominantly enriched signaling pathways were the FoxO signaling pathway and cellular senescence. CircRNAs are differentially expressed in bPOI, which might contribute to the pathogenesis of bPOI.
