Outline of Final Research Achievements

In a study using benign prostatic hyperplasia (BPH) rat model reflecting human stromal hyperplasia, we found that the expression of EMT markers in rat BPH tissues.
Next, in the examination using human BPH tissues, the expression of thrombospondin 1(TSP-1), which is known as an activator of transforming growth factor beta related with epithelial-mesenchymal transition, positively correlated with prostate volume and the increased prostate volume per month, and negatively correlated with BPH symptoms. These results suggested that TSP-1 may not only be a new therapeutic target for BPH, but also be a potential biomarker for predicting the development of BPH.

Academic Significance and Societal Importance of the Research Achievements

現在、前立腺肥大症に対する治療として、薬物療法がおこなわれている。薬物療法は、前立腺の弛緩と腺腫の縮小、血流改善によって症状を改善するが、必ずしもその効果は十分でない。前立腺肥大症の病理組織において間質成分が約70%を占めており、間質をターゲットとした治療薬の開発が求められている。また適切なタイミングで薬物療法から手術療法へと切り替える指標があれば、医療経済への負担を軽減することができる。本研究成果によって、TSP-1が新たな治療標的となる可能性、前立腺肥大症の進行を予測するマーカーの候補となる可能性が示された。
