Abstract
Background/aim: The aim of this study was to determine the effects of resveratrol on the alterations of cavernosal eNOS and LOX-1 mRNA expression in the hypercholesterolemic condition. Materials and methods: Twenty-one New Zealand white male rabbits were separated into three groups. Rabbits were fed with a normal dietary intake for the control group and a 2% cholesterol diet for the hypercholesterolemia and resveratrol groups for 6 weeks. Resveratrol 4 mg/kg daily was administered for the resveratrol group. Cavernosal LOX-1 and eNOS mRNA expressions were determined with realtime RT-PCR in all groups. The statistical analysis was performed with the Kruskal Wallis and Mann Whitney U tests. Results: We found no difference between mean LOX-1 mRNA expression levels in the three groups. Lower mean eNOS mRNA expression level was determined in the hypercholesterolemia group when compared with the control group (P = 0.011). Mean eNOS mRNA expression level in the resveratrol group was similar to that in the control group but significantly higher than that in the hypercholesterolemia group (P < 0.001). Conclusion: This preliminary study demonstrates the beneficial effects of resveratrol on cavernosal eNOS expression. The presence of cavernosal LOX-1 expression was also shown for the first time. Resveratrol may be an alternative option in hypercholesterolemic erectile dysfunction with further studies supporting its beneficial effects on the corpus cavernosum.
