Outline of Final Research Achievements

The study objective was to elucidate the effect of Vascular Endothelial Growth Factor (VEGF) on bone. The subjects were community-dwelling men (n=611) and women (n=1,111), whose VEGF gene SNP (-583C/T), bone mass, bone metabolism markers, and confounding factors were measured. After adjusting for confounding factors, VEGF SNP was not associated with bone mass or bone metabolism markers in women. However, in men of age <70, TT type showed a borderline association with higher bone turnover, whereas in men of age >=70, CC type showed a borderline association with higher bone mass.

Academic Significance and Societal Importance of the Research Achievements

VEGF遺伝子多型は、女性では骨との関連は見られなかったが、男性において、Tアレルが骨に不利な影響を及ぼす可能性が示唆された。不明な点も多い男性の骨粗鬆症の病態生理の理解に寄与するものと考えられた。VEGF遺伝子多型と骨の関連をみた研究は、数少なく、日本ではまだない中、本研究はVEGF遺伝子多型と骨の関連の生理的多型性を、関連因子を考慮して検討したものであり、人類学的に意義がある。
