miR-423 is strongly involved in sow follicular atresia. A and B miR-423 was markedly decreased in sow atretic follicles. A RNA-seq data. B qPCR. HF, healthy follicles; AF, atretic follicles. C–F Correlation analysis. Sow follicles and follicular fluid were collected, and the GC density in follicular fluid was detected using a cell counting plate, E2 and P4 concentration were measured by ELISA, and correlation analysis between miR-423 levels and the GC density (C), the P4/E2 ratio (D), E2 concentration (E), or P4 concentration (F) were carried out, respectively. Data represented are mean ± SEM for at last three independent experiments. ^**P < 0.01
