Melatonin Reduces Androgen Production and Upregulates Heme Oxygenase-1 Expression in Granulosa Cells from PCOS Patients with Hypoestrogenia and Hyperandrogenia

Figure 8

Melatonin promoted HO-1 expression, reducing IL-18 levels in human ovarian GCs from the PCOS patient. PCOS GCs supplied with melatonin or its inhibitor luzindole. Transcription and translation of inflammation and oxidative stress-related genes were examined: IL-18 (a), iNOS (b), NOX2 (c), and HO-1 (d). in each experiment. Data are shown as . Different superscript letters (A, B) in each column represent statistically significant differences between different groups (). (e) Schematic illustration of the proposed mechanism through which melatonin promotes CYP19A1 and HO-1 expression and reduces IL-18 expression in human PCOS ovarian GCs.
