Abstract
Background Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is identified as a urinary andrological diseases that afflict men due to various discomforts. It is urgent and meaningful to develop the novel and effective treatments as a result of the unclear etiology and dismal therapeutic effect of CP/CPPS. Lycopene exerts a crucial role in numerous chronic inflammatory diseases owing to its potent antioxidant capacity. Objective This study aimed to observe the effect of lycopene on CP/CPPS and to explore the underlying mechanisms. Materials and Methods A CP/CPPS model with complete Freund's adjuvant was established in this study. Afterward, intragastric lycopene or corn oil was administered daily for 4 consecutive weeks. Finally, the cardiac blood and prostate tissue samples were collected from rats to carry out related evaluation and testing. Results It was found in this study that lycopene alleviated changes in prostate histopathology compared with those in the complete Freund's adjuvant‐induced CP/CPPS model rats without lycopene treatment. Furthermore, lycopene was suggested to reduce the levels of chemokines MCP1 and MIP‐1α, down‐regulate the expression levels of cytokines (such as TNFα, IL‐1β, IL‐2, and IL‐6), and up‐regulate those of CAT, GSH‐PX, and T‐SOD, decrease that of malondialdehyde. Moreover, it also inhibited the phosphorylation of MAPKs, NF‐κB, and enhanced phosphorylation of the Nrf2 in the CP/CPPS rat model. Discussion and Conclusions The findings in this study suggest that lycopene exerts potent anti‐ CP/CPPS Seffects through alleviating inflammatory response and oxidative stress, which is probably attributed to the interaction of NF‐κB, MAPKs, and Nrf2 signaling pathways in rats. As a natural antioxidant, lycopene may serve as a promising pharmaceutical preparation for treating CP/CPPS.
