Expression profiles of circular RNA in granulosa cells from women with biochemical premature ovarian insufficiency
2020
Aim: To identify the expression profiles and potential functions of circular RNAs (circRNAs) in granulosa cells (GCs) from women with biochemical premature ovarian insufficiency (bPOI). Patients & methods: 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. Results: 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. Conclusion: CircRNAs are differentially expressed in bPOI, which might contribute to the pathogenesis of bPOI.
