Low-dose spironolactone abates cardio-renal disorder by reduction of BAX/inflammasome expression in experimentally induced polycystic ovarian syndrome rat model.

| Abstract |
The impact of low-dose spironolactone (LSPL) on polycystic ovarian syndrome (PCOS)-associated cardio-renal disorder is unknown. Therefore, the present study hypothesized that LSPL would ameliorate cardio-renal disorders in experimental PCOS animals. Eight-week-old female Wistar rats were allotted into three groups. The control group received vehicle (distilled water; per os (p.o.)), the letrozole (LET)-treated group designated as PCOS group received LET (1 mg/kg; p.o.), and PCOS+LSPL received LET and LSPL (0.25 mg/kg, p.o.). The treatment was done once daily for 21 days uninterrupted. The experimental PCOS rats were characterized with insulin resistance, as well as elevated testosterone and luteinizing hormone/follicle-stimulating hormone, with a significant increase in cardiac and renal lipid profile, oxidative stress, inflammatory biomarkers (nuclear factor-κB and tumor necrosis factor-α), lactate dehydrogenase and lactate content and decrease in cardiac and renal antioxidant system (glutathione peroxidase and reduced glutathione) compared with the control rats. In addition, immunohistochemical assessment of cardiac and renal tissue showed significant expression of inflammasome and B-cell lymphoma-2 associated X-protein (BAX) in animals with PCOS. Nevertheless, these perturbations were attenuated following the administration of LSPL. Collectively, the present results suggest that LSPL attenuates PCOS-associated cardio-renal disorders by reduction of oxidative stress and BAX/inflammasome expression.
