October 2025 in “Molecular Genetics and Genomics” June 2026 in “Biomolecules and Biomedicine” This study examined serum phoenixin isoforms, PNX-14 and PNX-20, in 90 women with polycystic ovary syndrome (PCOS) and 60 healthy controls, finding that both isoforms were significantly elevated in women with PCOS. They correlated positively with anti-Müllerian hormone (AMH), insulin, and luteinizing hormone (LH), and negatively with sex hormone-binding globulin (SHBG) and HDL cholesterol. The study used various statistical analyses, including ROC analysis, which showed moderate discriminatory performance for PNX isoforms. Although PNX isoforms were associated with key reproductive and metabolic parameters, their diagnostic utility is limited, and further research is needed to confirm these findings.
