The protein microarray detection results showed that the expression levels of CCL5/RANTES, CD40 ligand/TNFSF5, complement component C5/C5a, CXCL1/GROα, CXCL12/SDF-1, IL-1ra/IL-1F3, IL-8, IL-13, IL-16, IL-18/IL-1F4, MIF, and serpin E1/PAI-1 were obviously increased in PCOS compared with the healthy women (P < 0.05) (Table 9). This evidence concerns the gene CXCL8 and polycystic ovary syndrome.
