The study suggests that finasteride prevents the symptoms associated with BPH by regulating angiogenesis, reactive oxygen species, ER stress responses, and inflammation.
Purpose: Benign prostate hyperplasia (BPH) is a common age-related chronic condition. Its pathogenesis involves androgen imbalance, inflammation, oxidative stress, and endoplasmic reticulum (ER) stress. This study aims to assess the protective effect of finasteride, a 5 alpha-reductase inhibitor, against testosterone propionate (TP)-induced BPH in rats and explore its potential mechanism of action.Materials and Methods: TP-induced BPH rats received either saline or finasteride (1 mg/kg) orally once a day for 7 weeks. Prior to sacrificing the animals, blood samples were collected. After sacrifice, prostate and tissue around the prostate were dissected from seminal vesical for further analysis. Body weight, prostate weight, dihydrotestosterone (DHT), 5 alpha-reductase type 2 (5-AR2), and prostate-specific antigen (PSA) levels were measured. In addition, HIF-1 alpha, VEGF, MMP-2 expressions in prostate, oxidative stress, inflammation, and ER stress responses were analyzed to understand the mechanism of action of finasteride.Results: Finasteride administration inhibited prostate enlargement, DHT, 5-AR2, and PSA levels in BPH rats. Additionally, finasteride inhibited angiogenesis markers such as HIF-1 alpha, VEGF, and MMP-2. Moreover, components of oxidative stress, inflammation, and ER stress responses were significantly regulated by finasteride treatment.Conclusions: This study suggests that finasteride prevents BPH-associated symptoms by regulating angiogenesis, reactive oxygen species, ER stress responses, and inflammation, another mechanism to explain the effect of the 5 alpha-reductase against BPH.
