Outline of Final Research Achievements |
A study using Tissue Microarray suggested that the association between prostatic stromal estrogen receptor expression and advanced prostate cancer chemoendocrine resistance was mild. It was suggested that normal prostate stromal cells may regulate the secretion of cytokines such as IL-6 and IL-8 through the elevation of MIC-1 in prostate cancer cells. It was suggested that cytokine secretion was increased in prostate stromal cells by interaction with periprostate fat and prostate cancer, and that this mechanism may be regulated by the expression of MIC-1 in prostate cancer.

Academic Significance and Societal Importance of the Research Achievements |
近年日本人において前立腺癌は著しい増加を示している。進行性前立腺癌には内分泌治療が有効であるが、いずれ内分泌抵抗性前立腺癌となり死に至る。我々はpilot 研究で,術前無治療や術前内分泌療法に比べ化学内分泌療法施行後の前立腺癌組織では間質エストロゲン受容体が高発現していることを見出している。前立腺間質エストロゲン受容体およびその下流シグナルであるサイトカインの関連を調べることにより化学内分泌抵抗性前立腺癌の発生機序解明および治療法発明につながる。
