Figure 6. Transcriptional dysregulation of circLDLR-miR-1294-CYP19A1 ceRNA network in granulosa cells of PCOS. The abundance of circLDLR (A), miR-1294 (B) and CYP19A1 (C) were compared between PCOS and non-PCOS control by qRT-PCR. (D) Expression correlation between circLDLR and CYP19A1. GAPDH was used as the internal control for circLDLR and CYP19A1, while U6 was used as the internal control for miR-1294. N=25 vs 25. The results were presented as mean ± SEM.
