Resveratrol Improves Cell Cycle Arrest in Chronic Prostatitis Rats, by C-kit/SCF Suppression

Area of Science:

• Urology
• Cell Biology
• Pharmacology

Background:

• Chronic prostatitis (CP) presents complex pathogenesis and treatment challenges.
• The c-kit proto-oncogene is implicated in prostate cell proliferation.
• Resveratrol, a Sirtuin 1 (Sirt1) activator, may influence CP progression.

Purpose of the Study:

• To investigate resveratrol's role in regulating c-kit expression in a rat model of CP.
• To assess the impact of resveratrol on cell cycle regulation in CP.
• To elucidate the mechanism involving Sirt1 activation.

Main Methods:

• A rat model of CP was induced using diphtheria-pertussis-tetanus vaccine.
• Histopathological changes were assessed via Hematoxylin and eosin staining.
• Expression of c-kit, stem cell factor (SCF), Sirt1, and cell cycle proteins was quantified using Western blotting and immunohistochemistry.

Main Results:

• CP model rats showed severe inflammation, increased prostatic epithelial height, and reduced gland lumen diameter.
• Elevated c-kit/SCF activity and dysregulated cell cycle proteins were observed in CP rats.
• Resveratrol treatment significantly ameliorated these pathological changes by activating Sirt1 and downregulating c-kit/SCF.

Conclusions:

• Cell cycle dysregulation is a key pathological process in CP.
• Resveratrol treatment improves CP by activating Sirt1, leading to downregulation of c-kit/SCF.
• Resveratrol shows therapeutic potential for managing chronic prostatitis.
