Outline of Annual Research Achievements

(1)選択的アンドロゲン受容体修飾剤(SARM)S42の抗前立腺癌作用の検討:2017年からの継続課題として、追加研究も含め、以下の研究がEndocrinology 2018に最終成果として掲載された。S42は去勢感受性のヒト前立腺癌細胞株であるLNCaP細胞と22RV1細胞の増殖を抑制した。機序として、ARの転写活性の抑制、AR, IGF-1R, IRの発現抑制及びErk-MAPKのリン酸化の抑制機序を認め、S42はDHT-ARのクロマチンへの結合抑制を介して作用することも明らかにした。CAG-LucLNCaP細胞をヌードマウスに播種しS42を投与すると、腫瘍形成抑制効果が観察された。(2)S42の培養筋管細胞(C2C12)における効果:S42は骨格筋ユビキチンリガーゼ(筋萎縮関連遺伝子)のAtrogin1の有意な発現低下とMuRF1の低下傾向をもたらし、骨格筋のタンパク合成促進に重要であるP70S6Kのリン酸化レベルを亢進させた。S42は筋の蛋白異化に抑制的に、蛋白合成に促進的に作用する可能性が示唆された。(3) Late-onset hypogonadism(LOH)診療におけるAMS、血中テストステロン(T)値の臨床的意義:総T値は男性のメタボ診断の優れた指標となることを明らかにしたが(EJ 2015)、長期観察によるメタボ発症予測値としての血中TTのカットオフ値は現在、検討中である。また、AMSの総スコア自体は、種々の血中T値との関連性が乏しい (Endocrine J 2017)。そのため、本年度は、AMSの各質問項目の中から真にT値を反映する項目を選出し検討した結果、AMS10、15、16、17の4項目による簡易問診票が、生物活性のある遊離Tの値をより反映し、LOH診療により有用な簡易問診票になり得ることを明らかにした(未発表)。
