Outline of Final Research Achievements |
trophoblast cells isolated and cultured from uncomplicated human placental chorionic tissue and immortalized human villous trophoblast cells were subjected to oxidative stress using a hypoxic environment. Measurement of primary metabolites was performed using a gas chromatography mass spectrometer. Multivariate analysis of the results suggest that changes in metabolic pathways such as glycolysis, gluconeogenesis, and TCA circuits are activated in a hypoxic environment.

Academic Significance and Societal Importance of the Research Achievements |
近年、晩婚、晩産が増加しており、妊娠高血圧症候群の発症リスクは高まっている。妊娠高血圧症候群の発症には種々の要因が関わっているが、その病態は胎盤虚血による低酸素が影響していると考えられている。この研究はヒト胎盤絨毛を構成する栄養膜細胞を用いて、虚血に陥った栄養膜細胞ではどのような代謝経路の変化が起こっているのかを明らかにすることで病態の更なる解明につながると考えられた。
