In addition, in order to supplement the genetic research on the internal mechanism of polycystic ovary syndrome, the author identified the core genes involved in the pathogenesis of PCOS through bioinformatics analysis, identified four central genes (RARA, KPNB1, REL, and MAP1B) from the PPI network, and revealed important drug characteristics and potential therapeutic targets of PCOS [11]. The gene discussed is RARA; the disease is polycystic ovary syndrome.
