GLIPR1 and polycystic ovary syndrome: Figure 4A showed an overlap between the DEGs of PCOS and RIF as a total of 11 genes (CHST11, FAM150B, GLIPR1, SLC16A6, MAMLD1, SLC46A2, ENPP3, HAPLN1, PLCXD3, FAM110C, GAS1). There was only one gene that overlapped the genes of WGCNA analysis (CCND2, Figure 4B). We speculated that these 12 genes might be related to the pathogenesis of PCOS and RIF and had a shared relationship (Figure 4C). Analyzing these genes for functional annotation and enrichment (Figures 4D, E), we sought to investigate the potential biological changes between PCOS and RIF.
