LINC-ROR and polycystic ovary syndrome: Additionally, the expression of LncRNA H19 (P0.05), Lnc ROR (P0.001), and Lnc MALAT1 (P0.01) was significantly higher in the PCOS group compared to the Vit D group.<h4>Conclusion</h4>These findings suggest that Vit-D plays a regulatory role in the expression of exosomal miRNAs and lncRNAs involved in PCOS pathogenesis.
