Abstract

Background: Primary ovarian insuff iciency (POI) is a reproductive disorder occurs to women before 40 years old, which affects their fertility and life quality. However, the mechanisms of POI remain largely unknown, approximately 50% accordingly. Circular RNAs (circRNAs) have recently been implicated in ovarian aging, but their potential as biomarkers was never investigated in POI. Herein, this study aimed to identify the role of circRNAs as a potential biomarker in POI patients.

Methods: CircRNA expression screening was performed in plasma RNA from f ive pairs of POI patients and age- and sex-matched controls using circRNA microarray. In the validation phase, 18 circRNA candidates were validated by quantitative reverse transcription polymerase chain reaction (qRT-PCR) in a cohort of 25 patients diagnosed with POI and 25 age- and sample storage timematched controls.

Results: Of 6644 differentially expressed circRNAs, 12 signif icantly upregulated and 23 signif icantly down-regulated circRNAs were identif ied in the POI patients compared with the control group, which showed as red points in the volcano plot analysis (p<0.05, fold change>1.5). Based on the evaluation of initial expression quantity and fold change values, 18 circRNAs candidates were selected for the validation phase. Hsa_circ_0000376 was significantly downregulated in POI patients compared with the control group in qRT-PCR (P <0.05). The area under the ROC curve (AUC) of hsa_circ_0000376 was 0.698 (95% CI 0.499-0.897). The sensitivity and specificity at the cutoff value of 0.685 were 73.3% and 60%, respectively.

Conclusion: Taken together, our study indicates that hsa_circ_0000376 may play potential roles in predicting POI.
