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。
