GLIPR1 and polycystic ovary syndrome: This confirmed the gene expression levels of the two diagnostic biomarkers, GLIPR1 and MAMLD1. Consistent with the data analysis, our results showed that GLIPR1 expression was upregulated and MAMLD1 expression was decreased in the granulosa cells of PCOS patients, (Figure 9A) while both GLIPR1 and MAMLD1 expression was reduced in endometrial tissues of RIF patients (Figure 9B).
