Keywords前立腺癌 / 脂質 / 腸内細菌 / 高脂肪食 / 制御性T細胞
Outline of Research at the Start

前立腺癌マウスモデルを用いて動物性脂肪摂取による癌増悪・進展に腸内細菌叢、脂肪組織炎症、血清サイトカイン変化、癌周囲免疫担当細胞浸潤が関連するかを検討し、得られた知見をマウスモデル、細胞実験およびヒト検体を用いvalidationする。癌増殖に対する腸内細菌の関与や、有望な関連分子が同定できたら再びマウスモデルを用いて、癌治療効果を検討する。①動物モデルによる仮説検討②動物モデル、細胞実験、臨床検体による検証③動物モデルによる治療効果確認の3部構成である。

Outline of Final Research Achievements

We assess the relationship among diet, gut microbiota, lipid metabolism and immune microenvironment during diet induced prostate cancer progression. We found that saturated and/or mono-unsaturated fatty acid promotes prostate cancer progression with alteration of orders Clostridales and Lactobacillales and modulation of cholesterol/lipid metabolism in prostate tumors.

Academic Significance and Societal Importance of the Research Achievements

特定の脂質摂取の前立腺癌増悪・進展への分子生物学的関係性が明らかになると、これまで同定されていなかった新規の前立腺癌治療標的発見の足掛かりになるのみならず、食事や肥満といった生活因子や腸内細菌変動による癌治療や癌予防戦略につながる可能性があると考えている。
