Research Abstract |
1. Adrenal androgen, DHEA, is important for recurrence of prostate cancer. Prostate cancer stromal cells and prostate cancer cells coordinately activate the androgen receptor through synthesis of T and DHT from DHEA. 2. Tranilast inhibits hormone refractory prostate cancer cell proliferation and suppresses TGF-β-associated osteoblastic changes. 3. We identified CTEN, one of important genes that is associated with paclitaxel resistance. Expression of CTEN recovered paclitacel-resistance.
