Dioscin protects against chronic prostatitis through the TLR4/NF-κB pathway.

Area of Science:

• Pharmacology
• Urology
• Cell Biology

Background:

• Chronic prostatitis (CP) is an inflammatory condition with limited therapeutic options.
• Understanding the molecular mechanisms underlying CP is crucial for developing effective treatments.

Purpose of the Study:

• To investigate the therapeutic effects and mechanisms of dioscin in chronic prostatitis (CP) models.
• To evaluate dioscin's impact on inflammation, oxidative stress, and the TLR4/NF-κB pathway in CP.

Main Methods:

• CP models were established both in vivo (rats) and in vitro (P69 cells).
• Dioscin treatment effects were assessed using histopathology, ELISA, enzyme activity assays, and cell proliferation assays.
• The TLR4/NF-κB pathway activation was analyzed via qPCR and Western blot.

Main Results:

• Dioscin treatment improved prostate tissue morphology and reduced inflammatory markers in CP models.
• Dioscin significantly decreased oxidative stress markers and inhibited the TLR4/NF-κB signaling pathway activation.
• In vitro, dioscin dose-dependently reduced lipopolysaccharide-induced inflammation, oxidative stress, and pathway activation in P69 cells.

Conclusions:

• Dioscin exhibits significant protective effects in chronic prostatitis.
• The mechanism involves the suppression of inflammatory responses and oxidative stress via the TLR4/NF-κB pathway.
• Dioscin represents a promising therapeutic agent for the treatment and prevention of CP.
